Well I do notice that I have some crankcase pressure. When the engine is running, and the oil cap is off, smoke/pressure will eminate instead of there being a vacuum. However, I done the glove test at idle, and not while revving the engine. So a piston ring may be wearing down.vtl wrote: ↑Fri May 31, 2019 8:18 am Hard start ups can be caused by worn/stuck piston compression rings. Engine builds compression for longer than it should, thus it rejects to fire for a bit until the compression reaches its level. Try to soak rings overnight in Seafoam or similar fluids. I recall now I did this 2 or 3 times in the first years after I purchased the car. I helps to remove the passenger side wheel and turn the crankshaft +/- 15 degrees from time to time to agitate the rings. Don't forget to change oil afterwards.
Switching to a thicker quality oil will also help. I use Red Line 10w40 for a few years, very happy with it. It does not turn to sludge, does not lacquer the inner surfaces and washes the engine.
Keep in mind, I am not a mechanic, anything too complex I would bring it to a shop for. But how would I have the piston rings soak in seafoam overnight?
