Could it be Valve clearances....?
I have ordered a VE injection pump dial gauge timing kit as well as a diesel compression test kit.... But could my crappy running and tail pipe vape chuff be a sign of over tight valve clearances?
Mitsubishi Manual suggests 0.2mm intakes and 0.3mm exhaust... I can report that only the 2nd cylinder is close to specification with a 0.18mm intake and 0.3mm exhaust valve clearance.
Cylinder 1 and 3 intakes are very tight 0.09mm and 0.1mm respectively. With the rest all being tighter than recommended in general. It appears the valve lash from the manufacturer was overtight and passed QC...I have contacted the ebay seller but I don't like my chances as they are requesting a licensed mechanics ID# as part of the warranty process... I did salvage the shims from the old head so I might be removing the SOHC and swapping shims over the weekend....
