Well the project is about to begin here in a couple hours. My buddy, who is a mechanic for Altorfer Cat, advised me to just change the intake gasket and not to mess with the head gasket since we do plan on getting rid of it in a couple months and that seems to be the only thing causing the overheating. He pretty much said the exact same thing you all said. I guess if for some reason the head gasket also ends up being faulty then I'll just have to tear into it again. I'm sure it will be much easier the second time around.
It's nice knowing that I have all of you guy's knowledge if I run into some issues along the way. I enjoy posting and getting advice but hopefully I won't have to chat with you guys for a few days although I have my doubts!
Thanks again and I'll let you all know how it goes.

I didn't end up starting until today but just finished pulling the old intake gasket off. It went quite well but I guess disassembly is the easy part.
Most of the manifold bolts didn't even seem tight. The manual said that you'd probably have to somewhat pry the manifold apart but it was as loose as can be. Could this be why the van leaked so much oil? I had to add a quart of oil about every 1500 miles and the engine is saturated in oil and grime.
You could easily tell where the gasket failed.
Just curious but what do you all use to cover up the engine to keep foreign matter from falling in while cleaning it? I just stuffed shop towels all over but didn't know if there is anything else that works better. I wanna give it a good cleaning.

If you have an old shop vacuum and scraper, that works pretty good, so you don't get crap down in the holes and valley. Use a wire brush (not a outdoor grill brush) and brake cleaner to clean around the ports. After you get it back together, change the oil before you start it.
It's not unusual to have loose bolts on those when you go to take it apart. I don't think I have had one where I needed a crow bar to get the intake to separate. Just make sure that when you put it back together that you torque those lower intake bolts to the specs noted on the paper that comes with your gasket kit. The order of tightening the bolts won't be on the paper, so refer to your service information.
Very important to make sure that your bolt holes are blown out and don't have anything in them. If you have oil or junk in there it will hydro-lock the bolt.
Oh wait...here is the sequence:

Thanks Discretsignals...I always appreciate the help and advice. Are stainless steel brushes okay to use or is a regular wire brush okay?
Some of the bolts were very loose. I bet if I would've tried I could've taken a couple off by hand. Guess it doesn't really matter now though.
It seems like I remember reading that new manifold bolts should be used or is that only recommended for head bolts if replacing a head gaset?
I'm kind of curious if the intake gasket has ever been changed. Is there a way to tell by the old gasket? Why is it that some of these Ventures have had the intake changed 3 times before they hit 100,000 and some don't ever need it at all or just at very high miles? Does it just come down to how you drive it, possibly the climate and just how well you have taken care of it?

Stainless steel wire tooth brush (small) works good when I do them. I just pay attention and make sure a bristle doesn't fall off down into the motor. Keeping the shop vac running next to the brush is a good idea. Don't use the ones you attach to a drill...lol.
The head bolts are stretch and have to be replaced. The intakes are reused. Make sure the rocker bolts are torqued to 31 ft/lbs after the holes are blown out. Last thing you want to do is strip out rocker hole threads or hydro-lock.
Have no clue as to why some nylon intake gaskets last longer than others. I am sure the engineer(s) that designed them are sitting at their beach house sipping on umbrella drinks. The permadry gasket should eliminate that problem.

I wonder how many have actually taken a wire wheel to it??!!
31 foot pounds....gotcha....I didn't take the rocker bolts out I just loosened them. Maybe I should to make things easier to clean?
Since we are going to be getting rid of it in a few months I'm going to take my time and clean the engine and components up real good. I probably won't start putting everything back together until tomorrow afternoon. I already know I have a couple of basic questions but will wait until I'm at that point so I don't jump all around. Figure it may help someone in the future who is searching for info if my questions are in order of reassembly.
I'm in the wrong profession....I wanna be sitting on a beach sipping umbrella drinks! Instead, I'm too tight to take my vehicles to a real mechanic! Nah....it's more of that I enjoy it and it feels good when it's up and running knowing I did it. I should say knowing "we" did it because I'm not sure what would happen without you all to help out. It also helps having my "insurance policy" That "insurance policy" is my buddy who's a mechanic for Altorfer Cat. He also works on cars on the side. The part I like about that is the discount and no tax on parts!

I know I was already told I don't need to get new manifold bolts but do have a another question about the bolts. Alldata dyi says this.....
"Important: The gasket kit part number listed below now includes the new bolts (4 long bolts and 4 short bolts) with the pre-applied threadlocker on them. It is no longer necessary to order the bolts separately when ordering gaskets."
Do I need to put any kind of loctite on the original bolts before installing or should I go ahead and get new bolts that already have it on there?
Also, if I have a cracked wheel can drill a new pattern in a Ford rim in order to make it fit the Venture? I just want to be able to drive it down the road. ha ha....Was hoping maybe that question would get my post locked at the top of the page for all to see! I'm guessing that probably isn't a good thing though!

Definitely a joke.... It was either gonna be the wheel question or whether or not I could grind down an electrical plug from a battery charger made in the UK in order to plug it into my American wall outlet.
You guys are great! I love how you tell it exactly how it is. Nowadays most seem to sugarcoat everything and it's one of the many reasons why things in our country have went down the crapper.
Maybe you guys should run for office? You've got my vote.

Hahaha......... I tell it like it is and many don't like me for it but all I can say is "who cares".
Nobody wants to spend money and that is the reason we are here in the first place but repairing today's cars is more than just waiving a magic wand or fixing anything for a couple dollars with knowledge that we are supposedly holding back from the public. Many things are difficult for us to even figure out with thousands of dollars worth of equipment and years of experience but some fool will come on here and get pissed when we can't just tell them what part has to be changed to fix the issue they have been ignoring for 3 years and 4 shops have told him it will cost $1,000 to fix..

I here you Hammer Time.....I'd much rather be told the truth and especially if my family's safety, my safety or anybody elses safety has even the slightest chance of being at risk. There are enough accidents on the road everyday with perfectly safe cars. I can't imagine how many more there would be if everyone thought they could hold a car together with duct tape and bubble gum.
I've only been a member here for a week or so but highly value the opinions. It's not like it's making your wallet fatter by telling us to fix it the right way or take it to a mechanic. Some people just can't handle hearing the truth and it can be dangerous. They often end up finding it out the hard way no matter how many times they were advised or warned.

Yep....I can see it now....despite all the warnings if someone would've finally said, "fine, just weld the sob on there", the forum would be shut down and someone would have a lawsuit on their hands. Not to mention the blood of some innocent victim on their hands. Lord knows I couldn't live with that guilt.

Quick question....when I purchased my thermostat last week they asked me if I wanted the thermostat gasket and of course I got one. The thermostat already has a gasket attached to it. The one they sold me and the one that came with the intake gasket set (I assume it's the same) looks like an o-ring about the size of a quarter. Does this o-ring just not apply to my vehicle? I can't see anywhere that it could possibly go.

It's probably the o ring either for the heater pipe that plugs into the top of the water pump housing or the o ring for the heater pipe that plugs into the lower intake manifold.

I may possibly be the one for the heater pipe above the water pump but the one that's currently on there is kind of a round flat one that fits in a groove on the pipe. The new one would fit tight but could wiggle back in forth within that groove. I may just leave the old one on for now since it's easy to get to if it does ever need changed. A gasket for the heater pipe that goes in the lower intake didn't come in the gasket set. Is that something I should really change? I hate to spend $10 in gas to get a $1.00 gasket but definitely will if it's advisable to replace. It looks to be okay with no cracks and I can feel it "hugging" as I slide the heater pipe in.

The old one is actually an o ring. It's not round anymore because it was sitting inside a hole. Lubricate the o ring and the hole it slides into with vasoline before putting it together.
Your call. If the o ring looks in good condition, you might be able to reuse it.

Okay....need a little help. I put all bolts in separate baggies and labeled everything. I finished everything up and then noticed one bolt that I forgot to put back on. I ended up taking off the alternator bracket and for some reason the tensioner pulley. I guess I kinda got carried away tearing crap out. I'm pretty sure it has to be a bolt for either the alternator bracket or possibly the alternator but I doubt it. I have 3 bolts holding the alternator in. Two in the back and the one longer one in the front. I know the alternator bracket takes 3 bolts but does the tensioner pulley bolt count as the third bolt? If not, I'm guessing there's a bolt hole behind the tensioner pulley that holds the alternator bracket on there or right around there and I'm just not seeing it.
This bolt is 3 inches long and has a 15mm head.
Any idea?
Thanks!

Reach around the back of the alternator and see if there is one missing down low.

Ya know what Hammer...I think you're right. It does seem like there was a long one that was towards the back rear of the alternator. Seems like 3 bolts would be plenty but what do I know. Obviously not much if I had a 3 inch bolt leftover!
The realtor is gonna be here in a half hour for a showing so will check later on this evening.
I sure appreciate all the help. I'll be sure to let you all know how everything turns out with it.

Since Hammer Time directed me in the location of the bolt I was able to bring it up a diagram on Alldata DYI and that's definitely the one. Two go in from the side of the alternator bracket and one goes in from the back in between and under the alternator and it's two rear bolts. I'll have to rotate the engine forward again and possibly have to pull the alternator to get it in. I wish I would've noticed the bolt before I put everythig back together but at least it's not one that's buried. I labeled and bagged all the bolts for each individual component as I took everything apart. When I went to put the alternator bracket on I took the bolts out of the bag and set them on the windshield above the wiper blade and that one fell off. I remember there being 3 but mistaked the tensioner pulley bolt for the 3rd bolt. Oh well, I knew someone here would save my @ss once again!
Going to put it in tomorrow and take her for a test drive. Keep your fingers crossed! I'll let you know how it runs.
Thanks again!

If I remember right (which is rare these days) there is a bracket or brace on the back of the alternator that can be removed to gain access over the top using a swivel socket and extension.

We had to go into town today so I was just now able to get the rear alternator bracket bolt back in there. I then attempted to start her up. It started! Being a dyi guy it feels so good to hear it start. Whenever I put stuff back together, and nearing the end, I always have that thought in the back of my mind wondering if I put everything back together right or if I forgot to plug in some electrical connector. Everything went very well. I know that's because I had everyone here to fall back on if I had some questions. I'm so thankful for your guy's time. If I'm every in your area when we are on vacation or something I'll be sure to stop by with a case of beer!
I'm going to finish bleeding off the air in the cooling system and take it for a drive. I'll report back soon.

Thanks Hammer Time.....Everything seems to be okay with it. The heater wasn't blowing hot air at first but once I bled off the air in the cooling system it worked just fine. Before I got started on it earlier this week I mentioned how it would sometimes crank over a few times before starting. I've started it off and on throughout the day and so far it's been starting right up and quicker than it has in a long time. I'm anxious to start it up in the morning so I can see if that part is also cured.
The engine had oil and grime all over for a long time. I'm thinking the intake and possibly the valve covers had been slowly seeping for a long time and that's why I had to add oil as much as I did. It will be interesting to see if this takes care of it. I also picked up an oil pan gasket but may hold off on that just to see what was actually leaking.
So, the van is running and we just received an offer on our house. It has only been on the market for 2 weeks so it has been a great day!
I can't thank all of you enough for all of the help and advice. Just the peace of mind knowing that you all had my back during all of this made it a very enjoyable project.
Thank you for a wonderful forum! I've been on a handful of automotive repair forums over the years and this is by far the best one!
