Hi there
I would like to test the compression on my 3b engine. It has 306.500 km on it.
It fires up and runs really nice, though, although it has quite significant blow-by, think. (I however lack any comparison and experience to really tell).
But I'm a bit concerned as my engine oil appears to get thinner only after 2000km from last change. Can't really tell whether it's getting more.
No issues with withe smoke, oil in coolant or cappuccino cream on oil, so rather not a head gasket issue..
Did a chromatography on the oil and it appears to have diesel in it..
Did an oil change (now with level exactly known to monitor whether it's getting more).
I'm thinking of worn piston rings or bore. That's why the compression test...
Manual says: Compression test trough glowplug seats. Well... Ok. Meter can be borrowed.
For testing, fuel injection has to be cut. Engine must not fire...
But my Question:
- How to best cut fuel in an easy and secure way?
There is no fuel cutoff solenoid but this witchcraft EDIC. Cutting power to this leaves it in default RUN-position, I believe, where engine can fire, still. Same with cutting the oil sensor. Can I force it's position to Stop by any means, and would that be sufficient?
- Any other suggestions how to cut fuel injection for compression test the easy way?
Thanks for advise
Best regards
