I sent it to a 4x4 workshop and was told they think it may have blown a hole in a piston.
I would like to do a compression test but I don't have a modern kit.
I have an older type compression tester that you just push against the hole and get a reading with motor turning over.
Would that be good enough to do the job? I was going to do this by removing the glow plugs.
Also the primer bulb doesn't get hard when I pump fuel up.
I removed it and tested it and the non-return valve works but once installed it won't get hard.
Is this normal?
