shaneo_1 Member 108 Member For: 17y 8m 17d Posted 05/01/12 01:59 PM Share Posted 05/01/12 01:59 PM Was going to do a comp test on my ute this weekend as I suspect I have a blown head gasket , getting pressure in the radiator, just wondering if its like older cars, disconnect coil coils in thus case, stop the fuel? Maybe by removing fuse for fuel pump. is this how u do it? I have been told to watch as ecu may play up if coil packs art connected.Can anyone explain the steps to comp test on ba bf thanks Link to comment Share on other sites More sharing options...

You will need a good compression tester which will reach the plug threads, as they are quite deep in the head.I have never had any problems cranking without the coil packs.

Are you trying to say that there is excess pressure in cooling system and its blowing hoses off or?? Link to comment Share on other sites More sharing options...

Only one good thing about this is when you pull the head off it will be sparkling clean, Cheers Edited 15/01/12 01:31 AM by Impellor Link to comment Share on other sites More sharing options...
