Oil pump pickup tube o ring color from factory.

[mdmcinti]

Hey guys I got around to doing my oil pan gasket today which I think is the culprit to my leak since it was factory and never been changed in 241k miles. I did the oil pump pickup tube o ring too. It was a bluish green one that was in good shape. I replaced with a new red flepro one. Is that a factory o ring or did some one go in there and replace it?

The one in my silvy was a reddish orange color. Replaced it with the felpro red and it's been fine. I did quite a bit if looking before I did the trucks, and apparently there were a few colors used.... so I guessed.

The Green one is the Original. You will have much better oil pressure now.

Oil could make a red one turn orange

Mine looked good too!! But it was old flat and hard.

it was in really good shape and it did not crack and fall apart on me like the red one I replaced on a previous truck I owned. It has great normal oil pressure with no issues before hand. The problem was is my oil pan gasket was leaking so I replaced the o ring as cheap insurance while I had it apart. If that is an original o ring, it went 240k with still more life left to go.

I thought the red one was for the trucks. The green and black ones went on the cars.

Mine started going down around 275k

That's what about 80 percent of the info I found said. But here is another case that the green could have been in a truck as his is green. So apparently gm did whatever it wanted at the time.
