Last week I saw some oil on the floor of my garage. It was under the left front corner of the car in front of the front wheel. Probably coming from the charge pipe connection to the intercooler. So, I took it to the dealer. At first they said there was some leakage from the valve cover. Ok, makes sense that it could be the PCV valve. They said they would replace the valve cover. Sounded like a good plan.

Then they didn't call me back when they promised. I finally got hold of them a day later and he says that called GM tech support and they think there's "too much pressure in the engine" (their words) and they want to replace the pistons and rings.

I assume they are concerned about the rings leaking and getting blow-by into the crank case. I'm a little nervous about this. I'm not entirely sure that this is the cause of the problem and haven't had any experience with this dealer before.

Any thoughts?

Thanks for the concern.

They've had my car for almost 2 weeks now and are "still waiting on parts". I am not at all impressed with the level of communication I'm getting from this dealer. For every 3 calls I make I get one back.

We'll see what happens next week.

I got my car back on Saturday, almost 3 weeks in the shop. But,they fixed everything!

They replaced:
- 4 pistons and rings
- Timing chain
- Intake manifold
- Valve cover
- Charge pipes
- Water pump (I didn't even mention this to them)

So far, so good. The only problem is the CEL is on - P0236. Could be from something they did. I need to connect my scanner and see if there's a boost problem. If so, I'll take it back. Or see if it clears itself.

I'd reckon that's a loose clamp or intercooler hose.
Yup, I'd reckon.

I ran the Torque app while I was driving today - the boost never got above 4 psi. I know boost pressure is weather dependent and all, but it was hitting 12 psi in the summer. What should the boost pressure be on a cold, dry day?

I'll take it back in and have them check the hoses.

I just noticed that the Dealer replaced my oil feed tube to the turbo with an insulated one!

They did me righteous!

Except that I'm going to be beat by a Prius on the way to the dealer tomorrow...

Update: Took my car back in to the dealer with the CEL on.

He said they couldn't find the problem but the CEL was off???

So, I drove off and sure enough the CEL is off. Plugged in my OBD adapter and went for drive. Boost is at ~9 psi - the car accelerates at a reasonable rate now. So it's fixed!

Looking under the hood, I see they did change the Turbo Boost Sensor in the air intake hose right before the throttle body. It may be the original sensor from the intake hose they changed- it has dust on it.

Not sure how a wrong/bad sensor would limit the boost AND set the CEL. Anyone know how this works?
