Some might have read about the problems I've been having recently after my turbo install, and well today after playing around with the tune for days and days I finally decided to start taking apart the car. Did a compression check on the two cylinders where the plugs were different, 0psi of compression on both, went further and did a leakdown test, put the tester on #6 and could hear air rushing out form #7... BLOWN HEAD GASKET Looks like the turbo might stay off until summer or until I get another daily driver I might sell the hotside and cold side piping and make a new kit positioning the turbo on the drivers side. I just want to know what caused it... ran fine when it made 10psi, it was running a little rich, but I didnt hear any detonation Looks like the car might be going back NA this weekend.
