72 911 T now running after 10 years! Ignition and chain tensioner questions.

Hi all,

Some of you may recall my household recently bought a tangerine, rust-free 72 T coupe.

Anyway, it sat for a long time, better than 10 years. After a lot of fuel system work, it fired up last night on the first shot. No kidding.

Here's a rough list of what it needed:

1. rebuilt injection pump (included in cost of car)
2. new fuel pump and related mounts
3. various fuel lines
4. new fuel filter
5. Optima battery conversion
6. oil/filter/etc.
7. plugs
8. injectors tested and cleaned
9. gas tank pulled, cleaned, sealed and reinstalled

We flushed all the fuel lines of the varnish like gasoline (it gummed up the old injection pump pretty tight).

Last night, at about 11:30 PM the little sucker fired up for the first time this century.

A few questions:

1. The coil tower is cracked. Getting a new coil is obviously no problem. However, I do have a brand new MSD Blaster 2 coil I was going to use in another car a while back and never installed. Is there any reason why this can't be used on this "T" with the Bosch CDI?

2. Upon initial startup, the car sounded great. Smoked a bit, but what can you expect? I would say it ran for about 15-30 seconds before we realized the injection lines were leaking at the injector/line juncture-not tight enough. After re-tightening, the car was started again. This time, a noise developed in the pass side chain cover. I know, I know... I shut it down right away. What's the inspection process for ascertaining the problem? The car has original tensioners, no Carrera update as yet. It did not stall or cough or anything when this ocurred. It probably ran for no more than a few seconds after the noise was first heard.

Thanks all,

David

I would open up the chain covers for sure and inspect. after that problem is identifed, and corrected I would change the oil for sure before startup. As far as the pump go's,it might be OK. Fuel pump should be OK fuel filter should go in the trash. The coil needs the correct Bosch one others will not work.It will kill the Bosch CD

Actually, the fuel pump and injection pump were both seized. That list is stuff we already did to the car. Anyway, we're going to take off the muffler, take off the chain cover and see what is up. Suspicion is that the old tensioner has collapsed at least partially. Looks like a good time to go with the late-style tensioner update.

It's probably a chain ramp. Yours will be brittle by now anyway. Pop off the chain covers and replace, even if they look fine.
