Thread: Sr20de no oil pressure.

Hello, I was on a drive while my b13 SER started to get a little hot. Then on the highway it started to die down and the oil pressure light flickered on and off and when I stopped, the light stayed on and I turned the key off, the car did die. I did change the valves about a month before this happened and just now started driving it. I checked the antifreeze and there was no milky substance same as the oil. I'm not sure what it could be?!

Oil on dipstick?

Yes, after the car Sat overnight I started it and it ran great besides a knock has now developed...

Not to be the devils advocate, but overheating->loss of oil pressure->knocking does not sound good at all...

I would be tearing down that motor while it still runs. If you don't have time, maybe someone else can make an educated guess?

Time for a VE.

Don't be too upset it happens

You did not say how much oil was on the dipstick and the condition of it. That alone will tell alot.
A cold engine with no oil will still run for a little bit before things get hot. A hot engine with no oil will seize up.

There is 3qts that is barely brown.

I came to the conclusion that the minor dented oil pan caused oil starvation. It was after I was entering the highway on a ramp.. But I was driving normally

Did you pull the pan and inspect the pickup? You can actually kind of open the "opening" (if that makes sense) of the pickup a little bit by bending to get a little more oil up in there. Not too much or else you can lose pressure (think of sucking on a small straw vs. a huge one - at some point its detrimental) I'm not sure how much engineering Nissan did on the pickup opening size, if any at all. I had a VE that had a dented oil pan and I enlarged the pickup a little bit and oil pressure went up a little bit. Just food for thought.

Did you hear it dent? are you lowered? sr20 engine is pretty stout even with lower oil pressure it can go for a long time (been there, done that with a dented oil pan and flickering oil light BUT that car was babied and driven very lightly when it was flickering and not highway speeds and oil pan fixed up made it all normal again) <-- that same car has 191k miles now (about 15k miles after the flicker problem) but it also never had rod knock and was never low on oil either.
