So, my 993 is having bad days. There is clank click sounds coming from the left side of the engine. Today a friend, vw tech looked at the car and and listened with a stethoscope and thinks the lifters are the reason for the awful knocking noise.
ordered the gaskets and lifters from pelican today and looking for diy write up but have not been able to find it yet.
I called a few places today they quoted me like $10k. Sounded a bit outrageous to me.
please let me know if you have any write up on this.
$10,000 to replace lifters? Good Lord. I've done this job to at least a half dozen 993s over the years. No need to remove the engine, and certainly no need to charge that kind of money.
If you were on the East Coast, I'd be happy to handle this for you.
I’m in Atlanta. Called two places today supposedly they work on aircooled Porsches both said the same thing. $10-15k depending...
I wish some of you were in Atlanta.

Have you tried Graham Everett Motorsport in Braselton?
My lifters were also making a ticking noise that didn't go away after warming up. Called around for quotes and heard ~$3-4k with full engine out. Well I decided to hold off as it wasn't getting any worse and lo and behold, roughly 9 mos and a few thousand miles later the noise magically went away after a long freeway drive. I still hear the occasional ticking that comes upon start up but then it goes away quickly. Anyways, that was almost 8 years ago so I'm still on my original lifters at 83k miles. Just some food for thought that it might just be a stuck lifter or something and might work itself out.

What I did, and suggest you do, is change the lower six yourself, or any trustworthy mechanic if you don't have time/tools. These are really easy.
Do the LHS first, of course!
From following many threads on the subject, and asking real people IME it seems that the lower cam covers and tappets are the ones that fail first.
Once you have the mufflers off, access to the lower banks is good.
Obviously you'll need new lower gaskets, you can change the lower plugs as well if they are worn, or just put them back if not.
All you have to be careful of is make sure each tappet is 'off cam' and so not under tension when you remove/replace - just rotate the engine when you need to - it's obvious by feel when the rocker has no tension on it
Then once out, just be sure when you remove the tappet from the rocker that all debris is removed as well.
I found that one tappet was clearly all over the place, with the seal missing, and the other 5 were fine - until I removed them and each seal disintigrated.
My noise has gone. If yours does not, then changing the top six is more difficult....
Note any damage to this one was done by me pulling it out!

Really great info guys. I truly appreciate all of it. I’m going to attempt this. Waiting for the new seals. The google doc with the pictures. Is no longer available unfortunately.
Some of this worries me but we’ll see how it goes.
