Want this question answered?
typical compression test reading fora diesel engine
pounds of compression per cylinder
3 - 4 per cylinder.
compression test or leak-down test.
It should be a high of 185 and a low of 140
Just did compression test on mine and the normal seems to be 160 -180
Cylinder bleed down.
Oil burning or loss of compression on any one cylinder. It may also be missing on one cylinder. A compression test will verify this.
Do a compression test on each cylinder looking for one that is significantly lower than the others.
A compression test will determine which cylinder(s) are at fault.
yes
It just means that the railway is not compressed. Say that the railway was compressed, then you'd make a compression check and the answer would be positive, but if it isn't it means it's not compressed. When something is compressed, it means that the temperature was too cold for the railway so it compressed. Hope it helped! :P WHAT???? this person is lost. Ok, when you do a compression test and you receive no compression, make sure your test gage is a working gage. with no compression this indicates that exhaust / intake valves are in the open position which stops the cylinder from sealing for compression, possible bent or broken valve,valve spring,or lobe on cam may be worn. Now if you have a low compression reading on a cylinder i recommend you spray WD 40 into cylinder sparingly and test again,called a (wet test ) if compression raises you have bad piston rings, if it stays the same, its a valve issue, possible piston failure
