Re: Compression test results
I only have three words for you....
LEAK DOWN TEST.
Do a leak down test to tell if anything is getting out of the chamber, and where it's going....
Your head is not cracked unless you are getting WATER DISAPPEARING from the radiator, or water in the oil.
The easiest way to check for even traces of antifreeze in the oil is with a freon sniffer.
Modern antifreeze contains halogens, and the sniffer will find them, just sniff the dipstick tube.
If you are loosing water, but it's not showing up in the oil, then do a block pressure test.
If you are still loosing pressure, you may try one of the fancy dye tracers to find the leak, or you may take the head off, use a block off plate, and pressure test again.
That will rule out the engine block it's self, and leave you with just the head.
Use a magniflux around the valve seats, (especially in between the seats) to look for the leak....
It' may be just a seeping plug, or leaking head gasket, so don't just assume it's a cracked head.
Look the head gasket over carefully for signs of a leak, or water tracking.
The crap in the combustion chamber may be just crap from a worn valve guide, or bad valve guide seal.
If it's guides, you will have to remove the head to fix, but it's not real expensive.
If it's a leaking valve guide seal, they can be fixed with out removing the head....
So good diagnosis is a must for your problem...
Try not to jump the gun too much, it may be a little bit of nothing (and often is).
