Porsche 996TT Project

This car came in under pretty bad shape. It has been bought and sold and bought and sold we think because it has had a major running issue. It would not move under it’s own power. Cam codes and misfires on 1 bank. After further investigation we are pretty sure this car was highly modified, then put back to stock after something bad happened with the engine. A few owners have tried to get it running, but nothing has come of it. After a more in depth look, the intake manifold was blown off of one side, so we decided to pull the motor and get a better look.

As I started to pull the motor, I realized a lot more was wrong than met the eye! Simple things like broken brackets….

Missing turbo heat shields which melted the intercooler ducting.

Blown off intake manifold.

Broken quick disconnects.

Homemade vacuum canisters.

Broken intake manifolds

And homemade muffler straps. Quite the collection! Since the intake was blown off on the opposite side as our codes, I decided to do a leakdown test which was not good. Looks like this motor will be getting pulled apart as we have something major going on internally.

Interesting. I also had the broken bracket for the cooling lines near the transmission and I also had to fix the intake manifold intake bolt attachment. probably broken by someone who forgot to disconnecting it while lowering the engine….The rest of the repairs you are mentioning are really badly done…Poor car….Anxious to see what you will found! Professor, If you are planning an instruction session from the crankcase build-up to the cams adjustment I would like to be part of the course LOL!!!! OMG that would be interesting!!!

    I can’t remember where I left off, but we ended up doing a leakdown test to make sure and got horrible results on bank 1. Had to tear the engine down, and found some serious issues with the cams, valves, and rods. Someone had been in there before and really messed things up. Engine is currently undergoing a full rebuild.
