77 911S

[turtle944]

Hey everyone. I have owned an '84 944 for many years and I reciently test drove a 77 911S. It was great! It has 110,000 miles and the interior and exterior are SUPURB! Its a targa top, but has new seals and doesn't leak (I got in it right after a huge downpore and no leak evident in the top. It has a worn clutch (makes a slight noise on the clutch engage and disengage).

I have a few questions though:
1.) How can I tell if its had the chain tensioner upgrade (if you can at all)?
2.) What type of performance mods are available?
3.) What are some common problems to look for?
4.) What can I expect for difficulty / cost of replacing the clutch (I have done this on my 944, which is supposed to be really hard)?
5.) Any other input would be great.

Thanks!
Brian

If you see the additional oil lines going to the chain covers as in this photo, then you have the tensioner update. It's hard to miss

The 2.7 motor has a reputation for pulling headstuds. There have been lots of threads discussing that issue.

Some other points:

3) Common problems are pulled head studs, oil leaks due to old seals, oil consumption due to excessive wear, various CIS problems (search for it in this board!), worn tie-rods , rusted heat exchangers, frozen brake calipers.
Do a decent PPI to be on the safer side.

4) Clutch repair involves removing and separating engine & tranny.
A P-car-familiar will do the job it in about 4-6 h, assuming no major problems with oil lines, frozen bolts etc.
Clutch kits are widely available. Check Pelican.

If there is a noise at engaging the clutch, I suspect that also the release bearing may be shot. If the noise is minor and shifting is still OK, there should be no further damage.

Hope this helps.

I have a 77 911. I used light weight presure plate. Also, new trans shaft seal, rebuild throw out brg. shaft controler, new flywheel and pres. plate bolts, check out crankshaft seal. Now is a good time to change oil pres. sender, engine oil thermostat O ring, engine breather seal, and anything else you might suspect needs attention. Do research first. I do mean do all your research because now is the perfect time to put in those extra hours that a mechanic doesn't get paid to do. You have tapped into one of the best sources of 911 information in the US, there is no longer an excuse for not having a perfect job.........Ron

Don't be too quick to discount the 2.7 as a problem child. They are among the most reliable forms of 911 transport. If you've sourced a car with thermal reactors and no oil cooler, then you'll be needing to spend a few dollars getting it right before you could call it truly dependable.

We have a hot climate here in Australia and I run an 11-blade fan, external "trombone" oil cooler and regular heat exchangers. My car has NEVER been over 100 degC, even in the red-hot temperatures that we can get from time to time.

2.7s are fast, fun and frugal. I couldn't be happier with mine.

Best of luck!
