While asking other Solstice/LNF owners if they're also experiencing the same leaks we are from the cam position sensor/high pressure fuel pump.... someone posted this. His Solstice is having this issue.

I'm too lazy to jack up my car and look, but might be worthwhile on your next oil change to sneak a peek at.

I did a search on the forum for EI09140 and hadn't seen this posted yet:

#PIE0003: EI09140 - Engine Oil Leak From Crankshaft Front Oil Seal (Engineering Information) - (Jul 17, 2009)

Subject: EI09140 -- Engine Oil Leak From Crankshaft Front Oil Seal (Engineering Information)

Models: 2009 Chevrolet Cobalt, Cobalt SS, HHR, HHR SS, Malibu

2009 Pontiac G5, G6, Solstice, Solstice GXP

2009 Saturn Aura, Sky, Sky Redline

Equipped with Engine RPO LAP, LE5, LE8, LE9 or LNF

Attention: Proceed with this bulletin ONLY if the customer has commented about this concern AND the EI number is listed in GMVIS. If the customer has not commented about this condition or the EI does not show in GMVIS, disregard the bulletin and proceed with diagnostics found in published service information. THIS IS NOT A RECALL -- refer to Service Bulletin 04-00-89-053B for more detail on the use of Engineering Information bulletins.

--------------------------------------------------------------------------------

Condition
Important: If the customer did not bring their vehicle in for this concern, DO NOT proceed with this bulletin.

Some customers may comment on an oil leak under the vehicle.

Further inspection will reveal the leak to be engine oil and show the leak is coming from the crankshaft front oil seal.

Cause
GM Engineering is attempting to determine the cause of the engine oil leak. General Motors has a need to gather information first-hand from the dealer technician DURING diagnosis and BEFORE repair. As a result, this information will be used by engineeering to help "root cause" the customer's concern and develop/validate a field fix.

Instructions
Important: GM Engineering is only interested in vehicles that have 16,093 km (10,000 mi) or less mileage.

First, verify the leak is engine oil using a leak detection lamp and dye. If the leak is engine oil and it is determined to be coming from the crankshaft front oil seal, please contact the engineer listed below for additional instructions. If the vehicle has mileage higher than 16,093 km (10,000 mi), proceed with diagnosing and repairing the vehicle based on information found in SI. Submit a Field Product Report with the repair information.

 

oooo, I'll be doing a change this evening. I'll report my findings

 

im a newb at this.

is this where the 2 sensors to the left of cyl 1 coil pack?

 

Sounds to me like the seals are weaker than the pcv's release pressure...... notice the "dont fix unless there is a customer complaint"........thats some BS in my book

 

Well, its the same stance they're taking on other LNF cars leaking from the top end too. Ignore us and eventually we'll go away? I'm sure people will whine & moan at me saying this, but I'm 99.99% sure this will be the last GM vehicle I buy new.

reign1, no this is a seperate issue. The other leak thats becoming common is from the drivers side cylinder head. You'll see the oil residue under the high pressure fuel pump. This would be a leak around your crank pulley, the seal behind it.

 

ohhhh oh oh oh.
ok


yeah HB SS/TC had that

 

I wonder why it just lists 2009 SS. Isn't it exactly the same as the '08?

 

sub'd

 

This has nothing to do with the leak at the fuel pump/camshaft sensor area, it is with the front crankshaft oil seal not even close to the others.

 

Someones never been to a GM dealership


Most will put twice as much oil in your car and tell you it has a super charger .

You must not know or experienced what kind of people you are dealing with

If you don't tell them the exact year they just assume things ..

 

IF you'd bothered to read the whole thread, you'd see that is well established. This is yet ANOTHER place this car might be leaking from. I think most of us know where the crankshaft is on an engine.

Also SSlobalt, I'd guess its because they assume all 2008's are beyond 10k miles?

 

Most likely the engine plant started using a different seal for the 09 model or the seal supplier replaced the current seal with one that doesn't meet gm spec, this isn't the first time this happened.

 

Winnar! I had this happen with my first oil change. Going on a hunch I checked my oil level when I get home and it was WAY too high. Go back in the next day and they confirmed they had put in 5.7L when the TC takes 4.7. The appropriate amount was drained off immediately and my account updated but I'm going to request every time it goes in that the work order say "4.7L Mobil-1 Synthetic" just to be safe .

If you don't pay attention and run that much oil for too long, a leak anywhere wouldn't surprise me, in fact I'd expect it. The engine would be swimming in the **** and have some mean pressure build-up.
