There is a reason why the pads are not easy to find - Porsche does not even list the pads or the tensioner as a wear item. I tried to get a dealership to replace my tensioner years ago, I was told it's not a wear item. 4 months later it blew. Most 32V 928 owners do nothing with the tensioner.

I was reading through the 86 service bulletin last night, and it shows an updated chain tensioner (different valve plate), but it must not be the same as the 87 tensioner.

PorKen

I'm thinkin' adapter to bolt on the S4 pad?

Flormat

Well, you're the inventor... What kind of adapter? Like a peice of steel to increase thickness of the block?

PorKen

I'd have to see it all for myself, but it looks like you could use a machined block of steel/aluminum to bolt onto the tensioner, which the S4 pad could then slide on to?

What are the measurements of the two pads?

If you're gonna do that AND pay 600 bucks why not just make new pads

I just heard this morning from a person who knows about 928 rebuilds and he says that they original tensioner should not be reused.... the superceded parts should be bought i.e the whole tensioner and oil line

In an earleir thread on the subject someone way saying that some of the thread holes for the oiline did not match up when he tried to supercede... I will look for the thread.

I just compared the old 928S tensioner with the one I replaced in my 944S a year ago and the spring tension on the S4 and 944S tensioner is about twice that of the old 928S tensioner. Are the newer style S4 and 944S tensioners pretty durable? I'm wondering about just using my old 944S tensioner with the new pad? I have access to another used 944S tensioner for the other bank on the 928. Or is that a bad idea... Any thoughts?

Like I said before - the only reason I know of for changing the entire tensioner on a 944S / 928S4 is due to the lower pad not being available. So if you found a source for the both pads:
1. Sounds like a plan
2. Care to share the source?

Flormat

No, I have not found a source. But my parts guy wants me to bring everything I have in see what he can do. Don't know what he has in mind but I'll find out and let you all know.

LO, I posted the thread about the oil line not fitting the updated tensioner! Im still waiting for oil line and its been over 6 weeks back ordered from Germany. As you can see in this picture the bolts for the J- tube superceded!

The one on the right is the updated Tensioner

Its possible to make those lines like its possible to make brake lines as well.

I was told that the lower pads for the 968 also were not available but that the upper pad would work equally well and that this is how Sunset Sports sells them. I asked Sunset and they only would say that "some people do that and we sell a lot." Perhaps it's a liability thing. I'd ordered a 928 pad out of curiosity since I'd heard that it was the same as the 968 lower pad and would work on the lower side of the tensioner...but it's much smaller and would never work on the 968. It's like the white one in the picture above. Then again, remember that I have variocam in the 968 and that for the 944/944S maybe they will interchange? I don't know. When my pads get worn, I'll probably replace the whole tensioner. At 72K miles everything under the cam cover looks pristine, making me think they may have already been replaced. It's not an easy job to replace all this stuff since you may have to pull the cams...and they don't come out if you don't take of the front off your engine...and while you're at it you might as well do the x, y, and z.

On 944s/968s the tensioner pads and cam chains ARE wear items. I don't understand why the 928 would be any different? When your chain starts wearing, it does damage to the cam teeth. While you have it apart, look very carefully at how well the cam chain fits into the cam teeth and look for wear. Cams are not cheap. I've seen fotos of running cars that were missing the tops of several cam teeth.
