Next issue: Oil pressure light flickers and is sometimes steady at idle
So, I think I finally solved the EGR port problem and I am trying to make sure this van runs for another 30-80K miles.
When the engine idles and the oil is pretty hot, the oil lamp (idiot light) on the dash flickers and is sometimes steady, but you can feel the engine doing it's thing while the oil light flickers.
I notice this mostly in gear at idle with the A/C on. The compressor shifts on and the idle will go down a tad bit and the oil lamp will be steady.
Also, I have noticed that the engine has a rough sounding idle at that point and think that the oil is just not getting to where it needs to go fast enough.
So, with all this being said, do you think it's time for a new oil pump?
Or, should I check the return in the oil pan?
By the way:
Compression tests all revealed the cylinders between 150-160 PSI
