Does this qualify?

Off to a ripping start.

The 968 family could have stretched a little longer in time........Modern Porsche Lovers should be thankful that the 924, 944, 928 & 968 paved the way for water cooled acceptance

Love that color

Does this qualify?

It still has 968 taillights so yes I think that fits the criteria.

And the engine! Well not anymore. Now it's a twin turbo 4L billet block but still based on the 968 block.

I was waiting for you to post a pic ?

[TINGY]

Just some random 968

[jakroo]

Very funny Tingy.......It looks just like my one but it doesn't have the same licence plate .

I've just uploaded some photos of the car.  I washed it and drove it the 160 metres up my drive to the road and parked it on the greenest grass I could find (it's sooooooo dry around here)

yeah, I know you have all been waiting patiently. I've wanted to do it but only found the time today to get it right - a clean car and some decent photos.  I had literally just created my Instagram account and uploaded some photos and went in to this thread to load my images and saw you'd beaten me to it!

Have had a 1994 968 manual for a couple of years and keep enjoying it more the longer with every drive. Have done waterpump cambelt etc. Should I worry about vario cam chain and pads in a car with 200ks with no mention of them being done before. I and previous owner use Penrite HPR 30 20W-60 and motor goes and sounds perfect.

Good to see thread on 968s as these are such a great car that don't get mentioned a lot.

Just from previous experience & seeing photos of ones that have let go ( big very very expensive mess ) we replace the tiny inexpensive timing chain ( between the cams ) & the 968 only timing chain nylon tensioner guide pads in the following categories }

968 that has been ONLY a road car but unknown previous driver habits / driving styles  , replace every 120,000 Kms  to 140,000 Kms

968 that has done some track ( club days ) but now one knows how many track days , replace as soon as possible & then every 120,000Kms to 140,000 Kms

968 that does mainly track "club days " with very little road kms , then replace every pre emptive head gasket change which all depends on how many track kms are covered & how its treated on the track , meaning how badly its flogged on the track ( all depends on the track driver ) & naturally the track  flogged  968 or any 944 for that matter only gets full metal head gasket

Thanks for that Bruce. My car fits in first category and looks like this will be next job on the car.

When you say 968 only nylon tensioner pads are there special pads for 968s

Thanks Murray

[Buchanan Automotive]

Yes , they are different to the 944S or 944S2 pads & like the 944S2 etc they are Porsche supplied only

Regards

Bruce Buchanan

[Cam Arnott]

What brand of metal gasket do you use Bruce?

Cheers

[Buchanan Automotive]

You will not need a head gasket to remove the cams , you just need the twin cam ( cam cover) perimeter seal / gasket + the spark plug hole seals & the 13 retaining bolt seals & probably the end cap seals etc

The head gasket thing I mentioned is just for track cars , not road cars

Hi Bruce

When would you normally change the tensioner on a 968 or S2? The pads come pre-installed on a new tensioner don't they?

[Buchanan Automotive]

The word "normally " does not mean much when we very very very rarely replace the timing chain tensioner with a new one , never need to unless its completely destroyed by neglect of the chain & plastic guides , so very rare to replace with a new one 

Are you confusing the chain tensioner with the 968 only cam belt tensioner ?

Thanks Bruce. No not confused. Was just curious whether the chain tensioner has a common wear-related lifespan e.g 300,000km. I know of one or two other shops that recommend replacing the whole tensioner rather than just the plastic guides.

It sounds like the chain and plastic guides are sufficient if the tensioner is still performing satisfactorily.
