Valve Stem Seals

First....Yes, I've searched. Now that we're friends again...

Does anyone have a link to a Valve Stem Seal DIY? I know it's a difficult(ish) job, but I'm doing the VANOS and valve cover gasket soon. Since I'll already be in there, I was wondering if I can do the valve stem seals as well.

All I know from the posts I've read is that some people suggest taking it to a shop (because it's easier to remove the head, etc.), while others mention putting compressed air into the cylinder while replacing the seals (beyond my knowledge).

Any help is appreciated.

Replacing the valve stem seal requires removing the camshaft and valves. You will need to re-time your engine again. If you need to ask for a DIY, then you are definitely not fit for attempting this job.

That was maybe a little blunt BUT, if you put a value of 10 on the VANOS/VCG job, with regards total time/difficulty then the valve stem seals would likely come in right around 108. You will also need to beg, borrow, steal or make/fabricate a couple of "special" tools/jigs.

I say give it a shot if you feel confident, you'll always get good advice/help here. BUT, do not think you'll get this knocked out in a day.

Picture (1) WITHOUT the springs OR

Picture (2) WITHOUT the sludge/springs

Thats how far you're going in.....put your boots on.

Good luck.

Don't buy spring removal tool from napa/autozone or any other alike store. They are useless.

We ended up using custom made spring removal for trucks (might have pics somewhere).

But either way, it's a pretty fun thing to replace.
