944T engine work continued

I got the 951 up in the air today and started poking around a little more. Always exciting to see what you will run into next. My plan was to retension the belts to the correct spec, then start on the headers. Ummmm not so much.

ROFL. Some people shouldn’t work on cars they aren’t familiar with, lol. We all have our moments, but this is AWESOME! Some things put a big smile on my face. Needless to say, this car is now tinfoil free.

I guess the heat shield must have rattled at some point….a bolt fixes that 😉 I think a few tacks with a welder might be a better solution.

Then I looked up and….argh. Waterpump leak. When the belts were done, the 25 year old original pump should have been replaced and updated with the newer style. That turned out to be the bulk of my day.

Removing the belts. The balance shaft belt was really tight, and the timing belt was really loose. We’ll get that fixed shortly.

And the belts coming off

You can just barely see my red dot near the water pump pulley, but it is wet around the bearing.

And the old pump coming off.

Now here is why you flush your coolant every couple of years and use a phosphate free coolant. The reason is phosphate eats aluminum over the long term. Here we see a prime example of it. Notice the sealing surface of the pump has eroded away. Not good. Keep your fingers crossed that some aircraft permatex will catch enough of the sealing surface to keep the pump leak free. Otherwise out comes the motor and it will have to be tig welded and resurfaced. Not good.

And the new pump on and belts going on. I would have liked to coolant test it first, but my radiator hoses won’t be in until tomorrow, so here is to positive thinking!

And the belts back in place.

It is truly scary to see what some mechanics do to “repair” a car.

Might I ask what the tin foil was supposed to be for or do?

    Well they were worried about the government taking control of the car, so they covered it in tin foil 😉

    Actually they were trying to solve a starter kickback issue. Unfortunately, they created an electrical fire hazard as the positive cables were wrapped in this stuff. Likely the issue was the DME going bad and causing a misfire/backfire on startup, causing the kickback.
