617 strange black smoke issue.
617 strange black smoke issue.
so far I have done the following:
changed the oil-
Valve adjustment-
Checked timing chain stretch (has some but within tolerance) and timing looked good
compression was between 405-420 across the cylinders.
Swapped all the injectors with a rebuilt and tested set.
changed the air filter
Anyone have an idea what else I should look for? Other than the big puff of black this thing runs really well, starts within one engine revolution every time even this morning at 16F. Turbo spools fast and it pulls well, just blots out the sun behind me
I picked up a fairly clean 82 300td over the weekend. 162k miles but fairly neglected. It has a strange black smoke issue under heavy throttle or revving, and I say strange because I've come across this several times and none of the usual culprits seem to be it-
