So this is what 5 of my exhaust pipes look like.
Then we have this one. No sighs of a blown head gasket. No coolant in oil, no smell or steam out the pipes, no over pressurizing of coolant system. Piston looks the same as all the others and plug looks a little leaner then others. I did do a cold compression test and all looks good (about 165 on all) i do not own a leak down tester but have been looking for an excuse to buy one. Exhaust valve is very white with light lumpy build up, looks a tad worse then the last two cylinders. I know my last two cylinders run leaner then the others, probably poor choice of mods to lower intake.
The injectors are new 80lbs with maybe 3k miles on them. Car is not in running state right now so not allot i can test. I would love to do just a heat test on all 6 primaries to see if its a fuel issue.
I'm leaning towards a bad injector but would like to know what others think. Also any other test i should perform to help narrow the search.
