Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

Hey HT. Do you happen to have the rocker arm torque specs for a 98 Cutlass? I'm doing the intake for my sister's friend. Do you also have the torque specs for the intake? My Venture has the 3.4. If the torque specs are all the same as it I have access to alldata for the van so can just look there.

Also, how clean do you normally try and get everything? When I do my vehicles I get them spotless but realize it's probably not cost effective for a shop. I'm not charging her to do this cause she's a single mom and money is tight for her. I just don't know if I should spend hours trying to get everything spotless. I'm just wondering how clean you would normally get everything when doing an intake at one of your shops? I know you don't want to leave it filthy but I also know you probably don't want to spend a crazy amount of time cleaning everything.

Thanks!

Just blow it off with an air gun. Then slap it back on...LOL



124 in/lbs then 30 degrees (rocker bolts).

You should get the pushrod removal tool. Then you don't have to screw around with the rocker bolts.



If you get the Felpro permadryplus intake gasket kit ( MS98004T), it will have a paper in there telling you what the torque specs are.

Lol...well, it's not quite that dirty!

Not use to seeing you around in the morning during the week DS. Glad you are here today.

How does that tool work? I assume it compresses and you're able to get the pushrods out? That would be handy.

I didn't even think about the torque specs being in the kit. I'm not sure if I've ever picked up the directions on any of them. Guess I should though.

Thanks for the info and the help. I always appreciate it.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

You warm weather folks are an hour ahead so lunch break is a little later there. Sure wish I was in Florida right now. Cold and snowy here. Didn't get too much last night but had some ice to go with it.

That's a pretty slick tool and would come in handy. I'm gonna have to look into one. Probably costs like $200 though, huh?!!

There's quite a bit of grime on top of the heads. Is it okay to spray parts cleaner in there as long as I'm easy on it and as long as I change the oil afterwards? I scraped off what I could but can't get to all of it. I'm tempted to pull the springs so I can clean it real good. I can definitely tell this car hasn't had scheduled oil changes.

You don't want to be here. It's breezy and only like 80 degrees.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

I usually take a blow gun and blow the top of the intake off. Then take the thing apart and use a shop vac to suck out the sand, grit, old silicone and grime. The use brake cleaner, gasket scraper, and rags to clean everything up.

The valve covers, lower intake, and pushrods go into the parts cleaner. Also remove the throttle body and take the IAC, TPS off. Then clean that out with carb cleaner.

If there is a lot of sludge, be careful cleaning that out. You don't want that stuff to break off in big chucks and end up in the oil pan or you'll be ripping the oil pan off. Try to get the big crusties off, but don't get too carried away. If she switches to a synthetic or shortens her oil change intervals, the detergents should slowly eat away at it.

You can get that tool pretty cheap. Scored a Snapon one at a pawn shop for $20. Most parts stores can order one in for you. A few different companies out there are making them.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

That's not a bad price at all. Seems like most specialty tools are usually expensive.

Anyone have the torque specs for the intake bolts? I assume the sequence is the same as my 2002 3.4L. Middle, right side, and then left side.

Thanks

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

The torque is 13 Nm (115 inch lbs.) .

The sequence is the same for most any component. You start in the middle and work toward the ends while alternating sides.

In this case you have to tighten all the vertical bolts first and then the angled bolts always using the same pattern.


Here is the sequence

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

a 12mm/1/2" crowsfoot & 3/8s ratchet works really well as a pushrod removal tool....

Thanks HT.

Sidom...I have a 3/8 12mm crows foot. Is there anyway that will work?

Can someone please let me know what this gasket is for?

That's an old throttle body gasket for a 3.8L L engine.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

I think the 3/8s cf will be a little bit too small MG....You can try it... As long as it will fit over the frt of the rocker arm, then it would work....

In the past I tried a 7/16 cf and it wouldn't quite get on the rocker arm, a 1/2 would fit but was a tad loose but would work.......My s/o 12mm fits snug & works real well in tight spots. The nice thing about using a ratchet, is if you're in a spot where a straight on shot won't work, you can move the ratchet to get a better shot.... Now I'm talking about the "line wrench" style of cf not the open end regular style....I haven't tried that style but am guessing it might slip...



Personally when I go that route, I pull all the push rods out on the rockers that aren't up on the cam & then rotate the engine until the ones that are up on the cam come down & then remove the other push rods.. I found out that isn't required when I showed a cornfed okie that method & lent him my crowsfoot. When I saw him trying to pull a pushrod that was up on the cam, I told him to rotate the engine & he said "naw,,,,they'll come out".....He did get them all out without rotating the engine but I don't know if I would want to put that kind of force on the rocker bolts....Just slightly overtorquing them can cause the threads to pull out.......

I wouldn't recommend using to key to do that with the fuel line disconnected.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

Thanks DS. I didn't see anywhere it could go but thought I'd check with the pros.

Sidom...Thanks for the great explanation. I'm definitely leaving the rocker bolts next time I do an intake.

You lost me HT. Not quite sure what you meant.

If you turn the key on after disconnecting the fuel line, it will spray fuel everywhere.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

It works really well for me.....and in cases of warranty or "lets make a deal", you don't even have to remove the back valve cover, coil pack, alternator or alt bracket. You can get the pushrods out with everything in place.....

Thats a good tip HT posted since we don't know who will be searching this thread...Usually with an engine torn down to this point, you would want the battery to be disconnected and turn it over by hand...Since I'm familar with your level of experience I sometimes leave out some of the basics... I know you're not going to check your test light in a wall socket....Tongue

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

Thanks for all of the tips. It's always nice learning new tips and also knowing what I need to watch out for.

HT. I remember one time you mentioned there's a way to clean the carbon deposits out of an engine using ATF. There was quite a bit of sludge around the valve springs. I cleaned it all up real good but I'm sure the stems and pistons are filthy. Do you mind explaining to me how to do this? I think you slowly pour it into a vacuum line but I don't want to be guessing and hydro locking the engine. I think a good cleaning would really benefit this car.

Also, she just had the plugs replaced about 10 months ago but they looked like crap so I replaced them. What would cause this?

She's a single mom with 3 kids and I know she's barely getting by. I did this job for free and would also like to make sure she has a dependable car when hauling her kids around.

I think there might also be a problem with the battery draining. She replaced the battery before talking it to a quick lube place. They said her alternator was bad. I replaced it last night and also did a quick charge of the battery in order to start it to add coolant. The battery was dead this morning. I'm not sure if I just didn't charge it enough or if there is a draw. The charger said the battery was at 15.4 last night. It's a new charger so I would think it would be accurate.

Thanks guys.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

There are a lot of carbon cleaners that work a lot better than ATF. Plain water will clean the piston but doesn't do much for any other areas.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

The real worry when using cleaners is that with the heavy amount of crap there, if it does a good job it breaks it loose fast. That sends it down into the oil pump. Not a good thing. I've seen Seafoam clean sludge when added to oil, but again we have the worry of the oil getting contaminated. If you're gung ho on getting this stuff gone, check out the Youtube vid from Cooper Lake Automotive called what happens when you don't change your oil. I think I sent it to you once to show your sister to try to get her to take better care of her car. You see in that vid how they go about cleaning that engine up. Realize you will be pulling the oil pan if you go that route. There is no way to get all that junk out without doing so. The other way is to get some good oil in there and change it every 1500 instead of every 3000 for a while to knock the stuff out slowly.

Its nice of you to be willing to help her out. I'd impress upon her that your charity should be shown the respect of following your advice on her oil change intervals in the future.

Can you snap a pic or two of the valve and lifter valley areas so we can see just how badly gummed up this thing is?

Be careful cleaning the carbon out of the engine using ATF. It can wreck the O2 sensors and catalyst.

Re: Rocker Arm Torque Specs 98 Olds Cutlass 3.1 Sign In

Thanks for the tips.

Nick...I had everything put back together last night so don't have any pictures. I'm not sure if it's a good or a bad thing but I've finally done enough work on these 3.1 and 3.4 I no longer need to snap pictures or bag any bolts! I do remember seeing that video and showing it to my sister. Being that she's a woman I doubt it taught her anything and she'll continue putting it off! I've yet to meet a woman with any common sense! I told her if she's gonna put it off she ought to use Mobile 1 Extended Performance and still shoot for 3000 miles. Then again, if she used it, she'd probably end up going 30,000 between changes.

I think I might just leave the engine cleaning be and tell her to do what you recommended by changing the oil every 1500 over the next few changes. I don't want to be responsible for screwing anything up. It seems to be running okay anyway.

Like always, thanks for all of the help. I'll know in the morning if I need to chase down an electrical issue. I sure hope not.

Nick, he wanted to clean the valves and combustion chamber, not the crankcase.

He had mentioned a lot of sludge around the valvesprings too, thought he might be also looking to get that out of there.
