Fix for oil leak on '08-09's
Weve been having some new car having odd oil leaks from the behind the ac compressor, GM was doing an engineering investigation the last few months, and they finally got enough leaking cars to look at to make a determination on the leak. Heres what they found, and what they are telling us to do.
NO this isnot a recall, campaign, etc....NO you dont need to get this done if your car isnt leaking oil like this.
Models: 2008-2009 Chevrolet Cobalt, HHR, Malibu
2008-2009 Chevrolet Captiva Sport (Built in Ramos Arizpe, S in VIN Position 11)
2008-2009 Pontiac G5, G6, Solstice
2008-2009 Saturn Aura, SKY, VUE
2008-2009 Opel GT
2008 Daewoo G2X
with 2.0L, 2.2L or 2.4L Engine (VINs X, D, B - RPOs LNF, L61, LE5)
Condition
Some customers may comment about an engine oil leak.
Cause
Engineering has determined the cause of some engine oil leaks may be attributed to bedplate porosity at the rear A/C bolt hole mounting bracket.
Correction
DO NOT REPLACE THE ENGINE.
If the engine oil leak is diagnosed as coming from the rear A/C bolt hole mounting bracket, use the following repair procedure to correct the condition. The oil leak in this area is coming from a non-pressurized hole.
After the engine has cooled, clean the existing oil out of the hole and off the head of the bolt using a low VOC brake cleaner (P/N 12378392 or equivalent).
Apply a Teflon® pipe thread sealant (P/N 12346004 -- LOCTITE™ 565 or equivalent) to the bolt and reinstall.

Exactly, the car we are talking about are all 08-09s and have 100k mile warranties.
This procedure only pays 0.2 hours. It really is as simple as it sounds in the text.
Take bolt out. clean bolt and hole. coat bolt with 565 compound, reinstall.
(btw, 565 is good ****, it withstands up to 10,000psi when cured!)

okay i think i have this issue but im not sure, i put my car up on ramps to change the oil, and i noticed some oil on a bolt to the left of the oil pan, there are actually two botls on towards front of the car one towards rear they are about 4" apart it is the one towards the rear of the vehicle that had oil on it... i wiped it off and after finishing the oil change i noticed a lil oil there again, i've also noticed a few spots on the driveway but not sure if its oil sorta smells like it but not positive... if this is the bolt, can i just loosen the bolt and put teflon sealant on it and put it back in? just don't see a point in going to the dealership for such a simple fix.

knoxbox, it sounds like youre actually talking about an oil PAN bolt. You can put a wrench on it and see if its loose, and just snug it down a little if it is, but thats not what this info is regarding, If your leak from the pan bolts returns after youve cleaned it and retorqued the bolt, youll need to hit the dealer as your pan probably isnt sealed fully.

your correct it is attached to the oil pan had been about a week since i looked at it... but its the two big bolts and its actually the one towards the front of the car that has oil on it not sure if you can see it or not... anyhow.. today it wasn't leaking just appeared to have the oil i had wiped off before, so maybe it splashed out of the pan and onto that bolt and it had good aim to hit there... i dunno. i'll check it again at next oil change... the spots on the driveway are condensation from the ace i poored water on them and no oil present... so now im kinda confused haha.
big bolts on left the one towards bottom of the picture is the one that had oil on it.
