Post by bullstar »

Having a few problems with a rover 45 diesel L series engine, The problem is hard to start hot or cold lots of smoke looks like pump timing but checked and all looks ok.
done a compression test via pico and the results are below, does not look like the reference pics , could someone shed some light if the wave form looks ok, thanks colin.

On this one I cannot see any issue as all the humps look uniform, so why don't you try with a exhaust cold crank test with FLS?

This test is very helpful with this issues

Kind regards
