Compression test

[jibcl500]

All

Ive just done a compression test on this 95 CL500, the right hand bank of 4 cylinders are showing 200 psi on the test, the left bank are showing from front to back 230, 230, 240, 220 psi.

Can I assume anything is wrong with the right bank, cylinder head or valves etc.

Are all the Throttle Valves open? fully, that is can you remove the Electronic Throttle Mechanisms ? you know about oiling the bore's I assume?

So its still got that massive flat spot then jib ?

All plugs removed and engine cranked for 5 revs of engine, oil the bores??? to increase compression or otehrwise.

When you squirt some oil in the bores when doing this test, if the compression comes up, this would indicate worn rings or bores, if nothing happens its valves.
