1975 911s targa


1975 911s

Recommended Posts

I recently bought a 1975 911s targa. This is my first one and advice on what I should do to check it out would be helpful. It runs and I drive it weekly. I has been having hard cold starts. I have changed oil and air filter. Any suggestions after that. It does leak a little oil and clutch is real stiff. Help me relaim this beauty.

I have the complete collection of Porsche workshop manuals on CD from the 356 up to the 997, 987 and Carrera GT. Ofcourse that includes the 72-83 911 manuals, about 200 TSBs for the same model, and more..

Be very careful of the cold starts problem. That vintage (including my 76 S) were notorious for blowing the (CIS) air box because of the cold start valve leaking. Later cars and some cars were retrofit with a "pop-off" valve (flapper) to try and stop the problem. If you have to change the CIS air box the engine has to come out.

Make sure your car has the 11 blade cooling fan on the engine as some of the 75 and 76 cars were shipped with a 5 blade fan that just plain did not do the job.

Inspect or have some one inspect the head studs - as the engine aged these tended to snap or pull the threads out of the case. If you catch them early these are not to hard to replace with the reinforced studs.

If the car has a lot of miles the chain ramps should be inspected/replaced. While you are there you can upgrade to the later chain covers that had a built in oiler and then that problem will go away too.

Now with all that said these were great running cars and mine had 187,000 miles on it when I sold it. And a good deal of that was track time... :D
