Easy valve stem seal R&R
Maybe I'm a little behind the times but I just found out theres a tool set to replace the factory junk valve seals on your car. You pull the valve covers off, and remove the spark plugs. Then put compressed air into the cylinders one at a time. And use a special valve spring compressor. Then do the seals one at a time. just did it and it took 4 hours.. just thought I'd share

Everyone learns about it eventually. I've used one for years. The only drawback is that you need an air compressor which not everyone has access to.

Re: Easy valve stem seal R&R
Colincamaro/Stephen 87,
I bought the spring compressor tool and have all the seals to do the job. After starting the job on the #1 cylinder (front/drivers), that one went fairly well; however, looking at all the air pump hardware (brass lines going into the exhaust manifold) it is going to be a nightmare to get compressed air to the remaining cylinders. Did you do anything in particular to get around all the junk to go so fast? Also, any hints as to how to tackle the passenger's side? And finally, did you actually make sure each cylidner was at TDC prior to pumping full of air and proceeding with the replacements? I had a hard time judging TDC doing the work by myself. Any help is greatly appreciated!

Don't worry about where the piston is, it doesn't matter.

Don't worry about the crank moving either.

Re: Easy valve stem seal R&R
As long as your timing stays still, you're golden. Oh, and as long as that valve doesn't drop into your cylinder. I need to friggen do this, but I alas don't have a compressor. Rope trick time.

Re: Easy valve stem seal R&R
Use as much air pressure as you can lay your hands on. Let the crank rotate when you air it up, without chopping off any fingers.

Re: Easy valve stem seal R&R
Or, you can do it the way us lazy people do...
Put the piston at TDC; stuff about 2' of 5/16" nylon rope in the cyl; do it to it; pull the rope back out.
That way, there's ABSOLUTELY NO POSSIBILITY of ever dropping a valve in.
