Can you replace the front crankshaft seal on a Plymouth 1990 3.3 liter engine without pulling the cover using a seal puller after removing the crank pulley?
Thanks, Terry

Yes the seal can be changed without removing the timing cover. You may need a puller to remove the crank pulley. Some will slide off by hand after the bolt is removed; the next one will feel like its welded in place.
If you can get your hands on the proper seal removing tool that’s a bonus, but you really don’t need one. What I have done in the past is too drill a couple of small holes in the face of the seal. Then take a couple of self-tapping screws and thread them into the holes. Once the screw bottoms out; the screw will then push the seal out as you keep tightening the screw.
You just have to be very careful not to mar the crankshaft’s seal area, while you’re removing the old seal.
A couple of other notes while doing this; first off, you may need to polish the crankshaft’s seal area with a fine emery cloth, removing the old seal line. What I mean is the wear line, where the old seal has been rubbing on the crankshaft.
Many of the aftermarket seal manufacturers have taken this wear line into consideration when designing their replacement seals and change the position of where the seal rubs the crankshaft.
Secondly; lubricate the new seal lip where it rubs the crankshaft, with a light coat of grease or some form of petroleum based paste lubricant; a dry seal will fail within a few minutes.

Dear Dan,
Thanks a bunch. I have been to Canada a couple of times. Once my wife and I toured from Niagra Falls down to Windsor and visited Quebec, Ontario and some other places. Got robbed in Quebec visiting "Mont Real" in the evening. Ended our trip early. I was in this same 1990 van back in 1995. They broke the passenger window and got in, left our cameras but took our money and cards. Had to go back to Vermont with no money and no credit cards with a fabricated window of a pizza box and duct tape. Got a new window and cards and skulked back to Florida. That is when I learned you never want to buy a used window in the north, scratches from ice scrapers on every one I pulled. But we very much enjoyed visiting and want to come again sometime when we can. You were very helpful.
Sincerely,
Terry "Loonies" W.

That would bugger up a trip for sure; your story does remind us not to leave valuables in your vehicle. On the bright side (if there is one) this was a break-in, not a robbery with some A-hole threatening your safety.
I do know what you mean about used parts up here; vehicles take a real beating from Mother Nature.
I had one customer tell me that when he went into a Florida quick lube place for an oil change, before his trip back home. The kid doing the service went and got this camera too take a couple of pictures, of the underside of the car. He said he had never seen so much rust on a vehicle that was still on the road. LOL
To us up here, if there aren’t any holes it aint rusted. LOL
