JamesK Posted October 14, 2008 Share Posted October 14, 2008 Did you find it hard doing the compression test since you have to remove so many parts to get to the cylinders? What method did you use to disable the EFI? Link to comment https://www.sau.com.au/forums/topic/240095-how-good-are-these-results/#findComment-4195026 Share on other sites More sharing options...

trel Posted October 14, 2008 Share Posted October 14, 2008 thats very good compression. as long as they are even across all cylinders (as those results are) the motor is healthy.

There aren't that many parts. You can pull the fuel pump blade fuse from the row in the boot to disable the pump if you like but I've never bothered.
