Sparky Posted September 19, 2009 Share Posted September 19, 2009 Seems like a break in teh gasket between one and two.Any other headgasket symptons? Loss of coolant, overheating, oil in the water? etc Quote Link to post Share on other sites
Steve GT Posted September 19, 2009 Share Posted September 19, 2009 agreednew gasket would be my first thought lol if not then you might have to go down the engine a bit but id put money on head mate Quote Link to post Share on other sites

Steve GT Posted September 19, 2009 Share Posted September 19, 2009 well lets hope its head bud cause its easily replaced lol if not were looking at pistons possibly matey Quote Link to post Share on other sites
JackStar Posted September 20, 2009 Author Share Posted September 20, 2009 I dont think its that bad, just sounds like a slight mifire. still its an excuse for more upgrades, getting a bit of porting and polish done whilst its off.I wanted to get the head off today but its raining again, ive got the turbo side of things off, just got to wait till it stops raining.Jack Quote Link to post Share on other sites
