Ok I'been reading all night , about proper maintenance of the s2 16v engines
-So will be best to buy brand new chain tensioner or just the pads?
I never work in any major mechanic repair is this something you can do , or need to get Porsche shop?? how much they usually chareg for tensioner for it will need a new gaskest set or seal???
IF I take this task myself my car close to 100k should i replace the chain? or just pads will be enough? what others parts need to be replace ofcoures haveing new pads or new tensioners? whats gaskets wahst seal screws not sure? what parts I will be need?

Any one has a good write out about how do your belts and water pump in the s2 with pictures and easy steps

At the very least, change the pads - it's cheap (relatively speaking) insurance to prevent blowing your engine. There is some debate as to when the chain tensioner should be replaced. Some say that it should be replaced at 100K miles - it certainly couldn't hurt.

I just replaced my pads at 60K miles and have yet to button things up. However, I stripped out threads, due to excessive torque on one of the bolts that secures the tensioner - I dialed in the improper amount on a torque wrench. It was a foolish mistake. In all my years of wrenching, I have never damaged a thread. Anyhow, I now have the correct factory torque spec. With any luck, I will get her up any running this weekend or the next.

That said, I intend to put together a do-it-yourself (DIY) and post it up with photos that I hope will illustrate the steps required to complete the install. Besides the pads, I also replaced the valve/cam cover gasket (mine was split and torn) and the thick rubber rings that fit over the valve/cam cover bolts.

If you haven't turned a wrench much, may I suggest that you have someone that can assist you with the job. Obviously, we'll need the tools as well. Otherwise, you may want to a mechanic to do the job.

Replacing the belts is a tad more involved and a couple of specialized tools might prove helpful. Try Clark's Garage for some useful info.

thanks you so much , my idea is that , maybe invest 500$ in nice set of allen and socket metric tool kit couple nice ramps and nice jack and try to do it slowly and right after winter , I have car park not plan use in it all winter so was thinking get all info possible during this coming months and buy tools here and there (cuase now I have just screw drivers set) but that will make me more passionated of this new car, and sure will put the right new parts and do it with care , I know that sometimes even dealers do bad jobs may not replace the few parts that charge you and that kind of things so ,, still thinking about it cause there is not such diy for s2
WILL BE GREAT IN CASE YOU CAN POST YOUR PICTURES AND YOUR STEEPS THANKS AGAIN.

Hello, If you go to the link below and look at all his videos on DIY for the Porsche 951 you will have a good idea of how to fix your car yourself.

Another S2 owner with 230k miles.
We replaced just the pads on the original tensioner 3 times already with no issues. As far as the chain, 100k miles on the first one and the second at 200k miles and the third during the headgasket change. It is still cheaper to replace the chain than replace camshafts and cyliinder head assembly.
The tensioner assembly is fastened to the aluminum head so be careful not to strip the threaded holes in the head. If it strips it can still be fixed though.
It is still a fun car to drive.

911 ballin ______Just google this ___Rennlist DIY camshaft chaine tensioner 968___or since I'm no good at linking can somebody get this link over here for me (please John) .

[911ballin]

Ok I understand the pads are easy to replace.. but how long the chain last??? if i leave original chain in 100k how many more miles will it last?
then If i repalce the chain that is other job casue the cams will need to come out and also belts and also retiming is a pain in butt is that right???
my idea is repalce the pads myself really carefull, and take car to porsche shop to repalce belt and pulleys and water pump will cost me 1k I'm too scare to do belts and water pump myselft seems really complacated not that maney easy write ups about s2 ,, SHOWING DIY

It's not so much a matter of when will the chain break, but a matter of excessive chain stretch that will wear away the cam sprocket teeth. The chain isn't that much $$ anyway, but cams are if you can even find some. You have to remove the cams, which I've heard is a project, unless both the old and the new chain has a master link that can be undone. I would be safe and replace it now.

When you change the pads on the tensioner, you should be able to have a feel on the chain stretch. See how much play the chain has between the links.
When I changed my chain at 100k , it did not have lot of stretch and I felt that it could have lasted another 40-50k miles. The only reason the chain breaks is when the tensioner pads break up due to very deep grooves from riding on the chain too long and gets wedged between the chain and sprocket.
At least change the tensioner pads and decide on the chain replacement later. Drive the car and see if you decide to keep the car. If you decide to keep the car, then plan on changing the chain at 130k miles so you will enjoy it for a long time.

thanks so much thats what I was thinking about , I doubt taht Porsche will put cheap chain inthere will break or stretch in 100k, I was talking to my mechanic he said he has seem toyota with similar es chain going 200k not play in chain!
Ok where is best source for CHAIN PADS?

[desertt5]

[bazar01]

Yes but you will need the kit , one of best source for your S2 parts as far as I'm will be (Paragon Products.com) very trusty & reliable peoples with competetive price witch will send you quality parts & the rigth one. Why take a chance on god know where they are made parts .(DO NOT TAKE A CHANCE ON CHEAP PARTS FOR YOUR S2) exp---timing chain-$20.60 to $32.55___Camshafts chain tensioner pad kit -$127.30

[rickharrison]

NO!

The upper and lower pad are not the same. The lower is attached with 2 screws through the pad, the upper is not.

I was not replying to is question as will the pads be the same upper & lower. What I'm trying to tell him is that he will need both,and as far as the price is concern I did several check since I'm planning to buy some for my 968 & running price is in the 120s-130s for the kit all at the sources I look at.

[rickharrison]

The OP commented with only 1 part number and asked if they are the same, but they are not as we know.

The top kinda slides on. The bottom is screwed on.

Buy the kit if the tensioner moves up/down as it should...check the j-tube oil feed line to make sure its OK and not cracked/broken/leaky.

The chain will likely be fine, but as stated check the links for play. As the chain gets older the tensioner will allow for some stretch...mine looks brand new @ 158,000 KMS (nearly 100K miles).

What I'd really like to see is a new chain with a master link...the 911's had them for an important chain driven internal, so I think it would work here too. It would sure save you the headache of keeping the cams timed correctly. ( a project for spring if I do my lifters...but that is another thread )

The 911 chain is located in a housing outside the valve train and the S2 chain is located right in the middle of the valve train and camshafts. You don't want the chain master link clip to fall out and ruin the rotating and moving parts. That is why the chain is endless. It is not really hard to replace the chain and maintain the timing.

Ok thanks wondering is both pad soffer equal tear or is the top one the one gets more wear out of the two , cause in this case i will just replace the top pad! only 25 dollres, plus valve cover gsket set about 85$ and I will take challence to do it myself , will be the major mecahical work I have done !
