k my d15's burning oil i took the plugs out to check compression..i have oil in cylinders 1,3,4 and cyl 1=200psi, 2=200 3=210 4=210psi , but i have no blow by so i dont think the rings are shot could it be the valve seals or something....not really concerned bout the engine its gettin swapped just wondering tho..

thanks

 

head gasket possibly?? i have a bit of oil in mine too..just changed plugs and..doing a swap soon so..buying plugs and adding oil is cheaper right now ..big props too slapping a band-aid on it and..getting yourself to work and back

 

Its possible for the valve Seals. do a leak down test.
