daz gt turbz Posted July 16, 2011 Share Posted July 16, 2011 right guys, as some of you know my track time a japfest2 wernt kind to the car, did about 2 laps and the temp needle started bouncing around all over the spot so took it steady and it went back to normal, did another fast lap and boom above red so got it off track and pushed it back to the stand. opened the bonnet and coolent all around the expansion bottle and nothing left in it. so left it to cool for a few hours, filled it up with water and its started 1st time without a problem and drove the 150mile home without issue.took it to work monday with no problems but used the van all week to avoid the hassle, brought it home last night and when i started it up it had a missfire so thoiught it was hg for sure, but the missfire stopped within a few seconds. had some spare new plugs at home so popped them in last night just to try. took it to work this morning with no issue, so on the way home i kicked its teeth in and it was fine, boosting as normal.just done a compression test now,piston 1234all roughly the same. only thing i did notice is that piston number 3 spark plug was abit wetshined a light in and the top of piston 3 looks very slightly damp but got the best result from the compression test!?sorry for the long thread, any help off you guys is always appreciated!tar muchly!

ktl Posted July 16, 2011 Share Posted July 16, 2011 Get a combustion tester on the radiator or expansion tank after a good blast. Or another quick easier check is to go for a raz, take the dipstick out of the expansion leaving the nozzle inside the water and rev the engine high to see if any bubbles... this is all goto be done after a good blast.Is the spark plugs pinky (coolant colour) Quote Link to post Share on other sites
GT Phayer Posted July 16, 2011 Share Posted July 16, 2011 might it be unburnt fuel from the missfire ? Quote Link to post Share on other sites
james@cjperformance Posted July 16, 2011 Share Posted July 16, 2011 What rad are you running, are you sure it was topped up to full before your track session, overheating doesnt allways mean the head gasket is screwed. I would use and abuse it next week for work and let it sit in traffic etc. Quote Link to post Share on other sites

ktl Posted July 17, 2011 Share Posted July 17, 2011 goto your local garage ask if they got a tester, if they do ask them nicely that youll be back after a booted drive and if they can just stick it inside the expansion or just quickly pop off the rad cap. just watch your hands/eyes lol Quote Link to post Share on other sites

sam starlet Posted July 17, 2011 Share Posted July 17, 2011 Hey daz, i had this problem and managed to trace it back to a hair line crack in the rad, right at the top too. Only ever lost coolant when on track after a few laps giving it large.Might be worth a check.Sam Quote Link to post Share on other sites

daz gt turbz Posted July 17, 2011 Author Share Posted July 17, 2011 right guys flushed the rad, overflow bottle and pipes today. it took ages to get clear water out the rad, just red dirty old coolant. but finally it is all clear . all so changed the thermo and resealed all the housing. took it for a blast this morning so the rad flush could circulate the system, then flushed it all, filled it all back up and took it for another good booting and all is well guna use it for work all week and see what happens with it.
