Hello everyone, my daughters Chevy Cruze is driving me nuts. Here's what is happening.. I took it to Jiffy Lube for an oil change in July 2019, took it back to her to drive home. When she got home it seemed like the exhaust was coming out of every crevice in the engine compartment. I called a mechanic friend of mine to help with troubleshooting. He said the catalytic converter seems to be the problem. So we replaced the upper catalytic converter along with the V-Clamp since there was a rattling noise also. Smoke went down a lot but did not disappear completely. Also it sounded like there was an exhaust leak somewhere in the engine... loud. My mechanic friend decided to take the car for a spin to see if he could hear or feel anything out of the ordinary. He came back and said it was sluggish on acceleration and suggested replacing the timing chain since this could cause the exhaust smoke and acceleration problems if the timing had slipped. We just finished that job the acceleration seemed to be a little better but not great. New problem though, it is smoking like Willy Nelson, but the smoke is white and moist. I just filled up the system with antifreeze and it stinks. The loud engine noise is still present like we are running straight pipes off the exhaust manifold. His suggestion was a head gasket issue or a head issue to address the white smoke, but unknown about loud noise or acceleration. Anyone here come across this issue or have recommendations? The car is a 2011 Chevy Cruze (of course) 1.4L Turbo engine with 76,000 miles. Any help or suggestions would be greatly appreciated.

on mine I think it has to do with the turbo if u look under exhaust shield where the second turbo clamp is it’s leaking exhaust from clamp and burnt up my waste gate

Pull your coil pack, remove the plugs and send an endoscope into the bores. If the cylinders are clean or wet, you have an internal coolant leak.

Thank you for that information. So now the suspect is an internal coolant leak along with probably a bad turbocharger and hopefully that is all. This car ran so good prior to a recent oil change. Any new information to my problems would be greatly appreciated.

Could be a head gasket, or cracked cylinder. Pull the head would be my next guess. Why do you think the turbo is bad?

As I said before, I went to Jiffy Lube for an oil change and it drove fine except for loss of power every now and then. My daughter drove it home and it sounded like the exhaust manifold had come loose, (loud), and exhaust smoke coming from the engine bay. After checking it out, the exhaust was primarily coming from the area where the Turbo is along with the exhaust manifold and catalytic converter. We changed the cat and clamp, but still loud noise and smoke (grey). The mechanic I was working with said it sounded like a timing issue. So he changed the timing chain. No help except now white smoke. Now since everything was off the front of the engine I decided to go ahead and change the water pump too. The car has 76000 miles on it and I read somewhere that you should change the timing chain and water pump at 75000 miles. I could have a water/antifreeze leak since the mechanic didn't change the gasket for the timing cover which includes the gasket for the water pump. To be honest, I'm just guessing with reading all the post here because I can definitely admit that I haven't the foggiest clue what I am doing here. That is why I am posting my problems here trying to find a clue and then finding a mechanic that knows what they are doing. The car has been garaged since this all happened July 2019.

The water pump is covered by a special warranty - including gaskets

#14371: Special Coverage Adjustment - Engine Coolant Leak from Water Pump - (Oct 6, 2014)
Subject:14371 – Special Coverage Adjustment – Engine Coolant Leak from the Water Pump
Models:2011-2014 Chevrolet Cruze
2012-2014 Chevrolet Sonic
With 1.4L Engine (RPO LUJ or LUV)
ConditionSome 2011-2014 model year Chevrolet Cruze vehicles and some 2012-2014 Chevrolet Sonic vehicles with the 1.4L engine may have an engine coolant leak from the water pump. The pump may leak from the weep reservoir or from the water pump shaft seal, leading to a drip of coolant onto the engine or onto the ground. Over time, the loss of coolant will reduce cooling performance and eventually could lead to engine overheating. If this condition is not corrected, the “Service Engine” indicator light may come on, an “Engine Hot, AC Off” message may appear, a chime may sound, and the engine power may be reduced.
Special Coverage AdjustmentThis special coverage covers the condition described above for a period of 10 years or 150,000 miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Dealers are to replace the water pump if it is leaking. The repairs will be made at no charge to the customer.

Thanks, great information. Do you think I'm on the right track with the turbo?

You really need to post the OBD-II codes. Get a code reader or somehow go to an AutoZone and have them read.

Yes, I agree with you on that. That was in the back of my head. I will have to get a code reader and then post the codes under this post. Last we checked there were 11 or 14 codes. Some of them led us to the Cat, then to the Timing, because they were all toward fixing one or two things could fix all the codes. According to the mechanic I was trusting. I'll get moving on this. Thanks again.
