hookay. So. I need to buy a lifter, because after reasembly of the top end of my motor, 1 lifter is sticking and going clack-clack-clack. Not so good. I would rather buy a used one for 20 bucks than a new one for 62.

Do any part-out guys in So-cal have a lifter they know worked upon removal that I can pick up this weekend for 20 bucks?

I have lots of good ones. Bring a few 2 liter bottles of coke and I will give you one.

Cool. You have a PM.

Try www.928intl.com . They are in SoCal and sell used parts with a warranty. The part number will be U92810531106.

I've got a bunch also but they're all used. I'd personally recommend just getting a new one; you can order 'em from Pelican UPS ground and generally still get it next-day. If you're getting used ones, I'd also recommend letting them soak in some ATF (to loosen any crud in there) and then pre-load them with oil before installation to lube it up and help pump-up. Just what I've been told.

I would stay away from the new ones for now, even dealer supplied. There have been many well documented lifter failures from the only remaining company (INA) that still makes them for the 944. Try and find a used one until the QC issues on the new ones are worked out.

The abnormal wear problems were on engines with higher cam profiles and higher spring tension rates. For stock cam/valve and spring usage the new lifters/followers should be OK.

It is possible the old lifter can be cleaned. Some problems have been cleared up by running a product like Risolone for a short period. It is also possible to dissasemble the old lifter and clean the internals.

Hm. All good advice, thanks. I will pick up a couple used ones, and try cleaning and then soaking all of them as recomended to me by many people.

Dennis - How do you dissasemble them?

I would be interested in any info or links you have to doing this on removed lifters. I have about 30 spare used lifters that have sat for way too long. I'm picky about running cleaners 'in service' and this would be valueable information. Thanks

Did it work before you took it out? Are you sure it is a lifter making the noise?

Sometimes it takes a little while for them to pump up again after removal, how long did you give it?

Did you rev it up a little?

IIRC it was on the 924/944/968 e mail list that I saw the instructions by Markus. The technique described was to compress then quickly release. If that didn't work a plastic hammer or the drop method was used. There are no fasteners per say, just a friction fit and nothing to really wear out.

Yes, it did work before removal... I'll admit I haven't seen hydrolic lifters first hand before, so I was a little confused as to why I would be unable to remove the "shim" (it's been a good learning experience...). So, I think the one that doesn't work now is the one I was screwing with.

I ran the car for at least 5 or 10 minutes, and also revved it up a few times, but it still clacked.

I've got two now from Legoland, so hopefully my lifters will all be clack free. I intend to try my hand at cleaning all of them and filling with oil before hand this time around.

Sorry, I may not completely understand how that would work on a lifter, but it sounds like instructions for removing spring caps and collets? Excuse my ignorance

Dennis Wilson

Trevor,

That is about it except for a small disc. Oil pressure feeds in from the side and compresses the discs toward the valve. If shellac forms on the cylinder of a compressed valve, running the engine a short period will clean it up. If the inlet hole is plugged, removal and mechanical cleaning or replacement will probably be required.

I've yet to meet a lifter that wouldn't shut up. Most of them after 50 miles at most. Had one in dad's 951 that refused to quiet even after about 150 miles. I put a half bottle of Marvel Mystrey oil in the oil and it was quiet apon operating temp. Been quiet since. Good luck
