Hopefully you putting on new Chain pads, I would as that plastic is old hard and brittle, also look/see how deep the groves are.

They do not make new pads for the S3, so you will need to upgrade to the S4 chain tensioners, Mark at 928 international and or Roger at 928srus should be able to hook you up w/ needed new & used parts.

Covers looking good !

I cked them and the cam lobes they look almost new. I was told by prev owner this is a replacement Low millage engine.. After looking a the timing belt Cam gears and alike i am inclined to believe it..

I took the recomendation of a fellow lister and bought some Vapo-rust rust remover and soaked all bolts nuts and hardware in it it Works Super.. cannot believe the difference it even makes most of the Anodizing come back.

Ugh, I didn't do chain pads during my refresh they looked good even at 120k but would have done them WIWIT if I had known that switching out to the S4 setup was possible. Hopefully this doesn't bite me.

I didn't know either , I already installed both cam covers , so it not going to get done.. I thought Jaguars were expensive to build but this Porsche sheds a whole new light on things.

I hear you Mark. I will have to refresh mine at one point, not looking forward to it, fuel injectors, O-rings, new plug cables and plugs, hoses and more. Also looking at my chains in the cam covers ! Oh well it has to be done at one point or another.

Nice work so far.
PS* Take lots of pictures and document as much as you can, so people with 85's will be able to use your docs to make our lives a little easier. .
But I am partial to that year !

there is one PIA bolt right lower rear cam cover , the AC line is almost on top of it and very difficult to get our and in..

Tape those intake ports up with something. Don't want to go through what Kosmo Kramer is going through right now.

I have them stuffed with plastic bubble wrap and plan to vac them out before fitting ..and scope them too

Here is a great write-up on what you need to do the S4 tensioners and even a fix for the non-skirted '85 part.
The updated S4 unit is the way to go, even if the pads are not grooved they are brittle from 30 years of heat cycling. If they break, no joy will follow
