Compression test on a FSM

Bairdfamily6 · May 2, 2020

How do I do a compression test on this Super Major Diesel. I have excessive crankcase pressure and now it doesnt want to start without ether. any help would be appreciated. Thanks

Excessive breathing in crankcase points to broken or stuck rings as been said but could be head gasket
I know parts are cheap in uk but I don't know shipping
costs

Yeah thats what Im afraid of. Either way to fix it would have to take it down and a test wouldnt matter. IDK

Is there any coolant blowing out?
What condition is machine overall ?

There was no coolant blowing out and the oil is clean I'm checking the timing of the injector pump today hopefully it just got out of time. The machine is in good condition and it was running fine

Major man is the guy to ask for advice
I am surprised he has not replied

No need for me. you have answered the questions. Engine requires a strip down and new rings and liners if it is getting that much blow-by.
