whos got some info. i have always had a VERY SMALL amount of oil in this little pocket on the block, never noticeable on the dipstick between changes. I have heard about this a few times, how is the fix? just a new gasket??

Cam endplate gets resealed by your dealer, then it leaks again, if your dealer sucks like mine. I swear the oil leak must have been engineered into the car. Just tell your dealer there's a tech bulletin on it. They'll still probably blame it on you, saying you spilled some oil during the oil change, even though the oil is dirty. Then they'll put dye in your oil and have you return at the next oil change only to find that, OH WOW, it really is a cam endplate leak. I know there are some very smart technicians out there, but the norm seems to be just the opposite. Some of these guys have no troubleshooting abilities, whatsoever.

Is this leak on the backside of the engine almost like it would be coming out of the turbo? I took mine in for it and they just tightened the valve cover bolts up and told me to see if it stops. They didn't clean the oil off or anything.

SSlobalt

No. It's more on the transmission and front of the motor, under the hpfp.

It mostly ***** down to it's warranty work, and no one likes to do warranty work because it doesn't pay much and it creates additional paperwork/documentation to be submitted to GM for payment.

I had the leak under the hpfp fixed about a year ago. Now starting to leak again! Im pissed!

Ah that old leak, the plague of every LNf since they came out. There is a how to on how to do it urself so it's fixed permanently. And the reasons most techs can't trouble shoot is cause they were never into cars that much, they goto school and get tought how to do it by the book, they can think beyond their education, same thing with alot of computer techs I have found. School had its benifits and u can Learn alot, but learning stuff like this on ur own is always better in my opinion. Way better education, if u have the time and money, cause ur gonna break stuff lol

#09-06-01-014: Oil Leak by High Pressure Fuel Pump (Reseal Camshaft Cap) - (Dec 3, 2009)

Subject: Oil Leak by High Pressure Fuel Pump (Reseal Camshaft Cap)

Models: 2007-2009 Chevrolet Cobalt SS, HHR SS
2007-2009 Pontiac Solstice GXP
2007-2009 Saturn SKY Redline
2008-2009 Opel GT

Equipped with a RPO LNF Engine
Please Refer to GMVIS

Condition
Some customers may comment on an oil leak.

Upon further investigation, a technician may find oil leaking from the high pressure fuel pump area.

Cause
This condition may be caused by a camshaft cap that is not sealed correctly to the cylinder head, causing oil to leak out.

Correction
1. Verify the customer's concern.
2. Remove the fuel pump. Refer to Fuel Pump Removal in SI.
3. Remove the camshaft cover. Refer to Camshaft Cover Removal in SI.



4. Remove the camshaft cap (1). Remove all excess sealing material from both surfaces.




Note: It is critical during installation to ensure the bearing rear cap and cylinder head alignment is correct and the mating surfaces are flush.
• Ensure that all sealing material has been removed from the components and the sealing surfaces are clean and free of contamination prior to applying the sealer.
• Install and align the rear cap within 20 minutes of applying the sealer.

5. Apply a 2.5 mm (0.1 in) bead of sealer, GM P/N 12378521 (in Canada, use P/N 88901148) to the cylinder head at the number 6 intake camshaft rear cap mating surface.

Note: Apply the sealer to all locations centrally locating the bead on the rail.
• Run the bead to 5 mm (0.2 in), dimension “a”, as shown.
• Where the cap ends on the perimeter rail, extend bead approximately 4 mm (0.2 in) beyond edge of cap.
• Run bead, dimension “c”, 32 mm (1.3 in) from the edge of the cylinder head as shown.
• Run bead, dimension “b”, 20 mm (0.8 in) from edge of cylinder head as shown.

6. Install the number 6 intake camshaft rear cap.
6.1 Tighten the cap bolts evenly to 5 Nˇm(44 lb in).
6.2 Tighten the cap bolts evenly to 10 Nˇm(89 lb in).
6.3 Back the cap bolts out 120 degrees.
6.4 Tighten the cap bolts evenly a final pass to 10 Nˇm(89 lb in).
7. Install the camshaft cover and gasket, GM P/N 12609291. Refer to Camshaft Cover Installation in SI.
8. Install the fuel pump. Refer to Fuel Pump Installation in SI.
Important: When installing the fuel pump, install a NEW high pressure fuel pump O-ring (GM P/N 12600313), high pressure fuel pump gasket-to-cylinder head (GM P/N12595951) and high pressure fuel pipe (GM P/N12615401).

These cars suck *****. I can't wait to get rid of mine and buy a truck/boat/new fishing pole.

SSlobalt

BWAHAHAHAHAAA!!!

O9cobaltSS

I hear ya!

SSean

These cars don't suck, but in all reality it is still a 4-banger. It is a refined 4-banger however.

I decided to do some investigation on this oil leak. I clean all the oil off with some Simple Green and brake cleaner. Next I thought let's see if the 10mm bolts on the cam cover are tight. Sure enough I was able to turn each bolt about a quarter turn with a small 10mm wrench. I tightened the high pressure pump also but only the left side was loose. The right side required a socket with an swivel but it barely turned. I drove about 25 miles and re-checked for oil. There is no oil leakage now. I will keep checking. It appears that these bolts were not torqued tight enough. We'll see.

I've got oil slinging off the front of the engine. Everything is wet in that area. You guys think it is the crankshaft seal #PIP4718B? Is this common? 46k
