I bought this allegedly running-when-it-was-pulled 2L engine last year to upgrade to 2.056L just to find out it already had 96mm P&C.
Internals turns smoothly so I thought I'd do the flame test and clean the engine and put it back together. The engine runs strong and smooth. As I started driving it harder I noticed on fast deceleration the oil light would come on. If I let the engine speed come down naturally from about 2k, the oil light doesn't come on. Last night coming off the highway running about 3.2k, I immediately shifted into neutral to let the engine slow on its own, the oil light came on for a few seconds as the engine was now idling. I don't have an oil pressure gauge on it to see where the oil pressure is during operation. Any ideas of what to look at? Attached thumbnail(s)

QUOTE('73-914kid @ Sep 12 2016, 05:01 PM)  Also, what oil and weight? Valvoline VR1 20W-50. When this happens, I thought it may have been from oil sloshing forward but it happens when I exit a highway going from 3K+ to idle and before I start braking. I do need a gauge. Would this be an oil pump issue or pressure valve? |
