Given that my cooling system is getting over pressurized once again and the numbers are all over the charts, I ran the compression test with spark plugs in the 1st time then again with them all removed and the numbers still come back the same.
I'm noticing dirt like deposits (not rust) in the radiator, I keep getting this sudsy looking bubbles in my radiator as well. The insulators on the spark plugs for cylinders #1 - #3 have red spots on them where #4 - #6 look fine. Performance has been complete crap here of late, and the engine feels like its about to rattle itself to death. Also noticed here lately that Im losing coolant with no leaks once again.
Sounds like head gasket(s) to me. what do you guys think?
