For the life of me I cant seem to find where the oil leak is coming from. Anyone ever use a oil dye w/UV light to find a leak? Also, what brand do you recommend?

does it leak on the ground? or is it just covering different things on the bottom of the car?

It leaks on the starter and drips on the passenger y-pipe. Also, on the drivers side it leaks on oil filter and all over the oil pan and a bit on the ground.

Things that i've replaced intake manifold gasket, although the intake manifold seems dry. Also, replaced rear main seal, and oil cooler gasket. Only thing I havent tried is replacing the LT4 composite valve cover gaskets because i dont feel or see any traces of oil coming from the valve covers.

could it be from the oil pan gasket itself? A pluggesd PCV system or worn rings(overwhelming PCV system) can push oil past this gasket. spraying bottom of engine down with B12 Chemtool carb cleaner, drive the car a few miles at speed and come back and examine where the oil is coming from.

I had an oil leak that I could not figure out for the life of me. I did the dye and UV light to see where it was and figured out that it was coming from the front main seal and oil pan lip. It turned out that there was a little bend in the lip on my oil pan. Had to buy a new one. Check out the lip on your oil pan. Might be coming from there.

i got mine from my local GM dealer.

How much did it cost? I would assume GM would be the most expensive place to buy the dye & UV light...

LimitedEd1LE: Where did u buy your dye & light and how much did it cost?

I've seen the light and dye at Pepboys.

You need no stinkin' dye. Oil is oil. Cover your opticrap and clean the engine until there is no oil anywhere. Place "newprint" because it shows up best on the floor. Pull the fan fuse so it doesn't blow the oil anywhere and see where the oil drops from.

Play detective. I will see if I can find my oil consumption site and post it in a minute or so.

I just got the dyn at Pepboys. I don't remember the price for sure, but I don't think it was more that $15. I wanna say it was like $8.

For the dye we just put it in our oil and drive around the block? After were done we just do a oil change and all the dye will be out? It wont harm the internals i assume right?

Just put the dye in the oil, run the car a little, then shut it off. Jack the car up and take the uv light and glasses and find where the dye is showing up. There is your leak. Good luck.

P.S. The dye won't hurt your internals at all.

i got the dye at my local dealer for something like 4 or 5 dollars. i used a light i bought from mac tools a few years ago for air conditioning work but it was like $275. i'm sure you can find one cheaper if all else fails. i'd sure try cleaning all the old oil off and see where the fresh oil comes out, as already suggested. that would be the cheapest way.
