Race Car
Anyways, the car has started 4x out of about 12 attempts. If it starts, it dies within 5 seconds even with throttle plate open. THE ONLY way it will start is if about 2-3 capefulls of oil is put into the plug holes. This is the only way to get compression high enough. Then we have to pull the plugs, dry it/them out, pull fuses and start the process over.
The Timing was spot on, checked in two places.
The car is reading right at 45-46 psi Fuel Pressure when starting. This is with the stock FPR. We pulled the 3 bar one that was in. That seems high and why the car is flooding out?
Car has had an oil change. Mechanic figured about 1 probably 2 quarts of gas was in the oil.

In addition to diluting your oil drastically, that much fuel will certainly be washing all signs of oil off of your bores, which is likely a large factor in your "low" compression diagnosis. The fact that all cylinders are the same is a strong indication to me that your rings are fine.

Although it sounds as if the car is destined for the scrap pile... Would be a shame if either the tps or harness were causing a wot indication to the dme...

Seriously... larger injectors, running full tilt (WOT) at anything other then WOT WILL cause liquid fuel to be entered to the oil.. its just a matter of time!
Also causes many other bad things to happen...

Hey everyone, just got off the phone with one of the 944 racing shops here in SD.
Rings are bad.
Car had a leakdown test done and it will not hold compression basically at all. The seafoam simply unveiled an engine that is tired and what not. If anyone wonders, I am new to 951's, but not sports cars. I have had several American cars that were several hundred horsepower plus. This car I have had for a year now and driven it a total of maybe 50 miles. I have spent the year putting new and better equipment to run the car and sort it out.
Tomorrow the head is being taken off, and I am hoping the rings need to be replaced and then put back together with a quality head gasket. I hope the pistons are not toast. Wish me luck.
I poured 1 ounce of seafoam in and let it run for 2-3 minutes. Then poured in one more ounce after that. Then the car choked on the second ounce. The spraying was starting fluid trying to restart the car. I should have been more clear about that.
Oh well, it sucks but not the end of the world I guess.
I have an old huntley led wideband. Night Rider style. If this had not happened my next plan was to install a Zietronix after I passed smog.
I may need a new head, so if anyone has a good price on a Turbo head PM me.
I do really appreciate evreyone's interest and input.

Do you need a rebuilt head or just a good base head?

Hey Lart thanks for asking, because I will surely need something. If I don't contact you the place the car is at will. You have done alot of business with them.
The head will be off in the morning and we will have a much better idea of what needs to be replaced.

Taking the head off wont tell much about the rings. It will tell much about the cylinders, though.
I wouldn't have them waste the labor pulling the head if the rings are bad, though. It'll be easier on the stand.
Did they tell you they were going to pull the head, replace the rings, and install a quality head gasket? THAT would be a great thread.
