charlie_pank Posted March 3, 2003 Share Posted March 3, 2003 Apologies for using this forum for general head gasket info. I have found blatchat to be an invaluable source of knowledge on cars generally so thought I'd see if anyone had any advice on a problem my housemate's having with his track-car currently. Although he doesn't have a 7, there's no reason why the questions and answers couldn't be directly applicable to an X-flow, VX or K... At brands on Thursday 4 laps in (probably the most expensive 4 laps of his life!) Dan's golf started churning out white smoke. Back in the pits we all reckoned it was the head-gasket, he'd had a coolant leak a few days earlier so some localised overheating is possible. However, the usual tests on the expansion tank revealed no exhaust gasses in the water. When the engine is un-stressed there is no white smoke in the exhaust. The possiblities we have come up with (in order of expense): 1. Head gasket - we're replacing it next Sunday 2. Warped head - time for a skim 3. Cracked head - time for a skip! 4. Cracked block - time for a new car However, given the possiblities above, I can't see how coolant would get into the cylinders without exhaust gasses getting into the water. Does anyone have any ideas? Charlie'n'Kermit The plan is: there is no plan S5EVN Link to comment Share on other sites More sharing options...
Mr Locust Posted March 3, 2003 Share Posted March 3, 2003 Porous casting around the inlet ports?????? Best to get the head pressure tested/skimmed while it's off any way. Edited by - Mr Locust on 3 Mar 2003 17:59:18 Link to comment Share on other sites More sharing options...
