My pans a little wet and I would like to track down exactly where its coming from. I know this topic has been discussed. But I can't find what type of dye to use? Anybody had experience with dumping something in that will be friendly? Thanks in advance.

your friendly GM dealership should have some 4-in-1 dye

good for power steering, gas or diesel oil, ATF, and gas or diesel fuel

Awesome chris. Your help is appreciated.

no problem big greg

i'd sell you a bottle cheaper than that but the shipping would double the price (or maybe more)

I put the car up on ramps, clean everything up with brake cleaner, and climb under it again in about a week to find the wet spot . The brake cleaner practically eats the oil and grease making the underside of the engine bone dry.

I've done that and am still not 100% sure on if its coming from the pan itself or the level sensor

Can you take a picture? And how much oil is leaking (qts/miles)?

Not really leaking much at all maybe a drip on the ground every time a park. I notice maybe a half quart every 3000 miles or so.


The pan is wet and there's a small drip on the oil plug. The level sensor. and that's really it.

hmm, ok

usually a leak that small won't drip on the ground and will just kind of undercoat

the common leak points would be the half-case seal area and the oil filter adapter area (including the oil pressure switch)

sometimes valve cover seals leak but you should be able to tell that from up top and isn't very common for the '06+ style

I did just do the oil filter adapter. That slowed it down a lot. That is now dry. And the half case looks dry too.


And I've done the rear valve cover. The front is seeping I will get to that.
