Steveuk260.Esq Posted January 9, 2015 Posted January 9, 2015 Most common sign of head gasket gone is air bubbles in expansion tank. And overheating engine.

savage bulldogs Posted January 9, 2015 Posted January 9, 2015 Unfortunately head gasket is a possibility as pushing excessive boost into a engine can cause the heads to "lift". Especially without adjusting the fuelling/timing and monitoring the afr . Scoobs do normally blow combustion into coolant somtimes causing over heating , so a coolant sniff test would probably show hydrocarbons in the water. When you said it boosted ok if you've got a boost gauge what did it peak at ? As If it went over 1.2 bar it might have been fuel cut , which might indicate it's not blown the head gasket due to it holding boost 1
bambam Posted January 9, 2015 Author Posted January 9, 2015 Unfortunately mate that i cant tell you when i first got it i was too scared to look away feom the road lol and now its not connected as i snapped the t peice tryin to get it off when i thort that was the boost issue, but when i noticed i had lost boost it was showing about 7 psi
