Would they have to warranty the work for another year if they have to re seal timing chain cover a second time? BTW, is a 2013 with 48k miles. My powertrain ends in January, so, I feel as if they are trying to avoid the work. A Ford dealer never treated me like this. But when I make this appointment for the FOURTH time for this second leak, I feel like they are going to make another excuse. They told me of it did leak which it shouldn't, they would have to take the motor out again. WHAT DOES TAKE?! Other Chevy dealers won't touch it because they said it needs to be repaired by the place that originally fixed it. Anyway, drive it less than a 100 miles, and it's seeping again like I told them it would. I ask if they can just put a new crate motor. Replacing the timing chain is a complicated, time-consuming task that involves taking apart sections of your. He doesn't deny it, but says it should be fixed with tightening some bolts and THEY PUT RTV AROUND THE BOLT. The timing chain itself costs around 100-250, though some timing chain kits can go up to 500 A good timing chain kit will include all the gears, tensioners, and sometimes even the water pump. It was clear to see coming from the sealed area and pointed it to service advisor. They tell me it's a loose bolt on the chain cover and see the dye from it. So I take more pics of the day I got it back, Drive another 500 miles, and what do you know?! More seepage and oil traveling down to drop. When should YOU REPLACE the TIMING CHAINFirst, engine start at cold could reveal noises that, if left untreated, could lead to major repairs.Many newer cars. They said they would clean it up and that it was not an issue. I say it's BS and it was clear to see coming out of seal (I've taken tons of photos). So drive 600, made another appointment, and they tell me they didn't see any dye and that it was just residue from when it was originally fixed. Bring it to dealer, they agree with me and say they want to put a dye in it to see if it's leaking anywhere else and drive it 500 miles. I inspect, and see that oil is coming out of the timing chain cover once again and is seeping out of the sloppy mess of permatex (gray) they sealed it with. We left for a week of vacation beginning of July and noticed small drops of oil on the garage floor. Thank you.So! My timing chain cover was repaired back in December. I have a hard time thinking it's in the timing chains or one of the parts that's been replaced because the car runs exactly like it did prior to replacing the parts. But the car won't run good or long enough to do that. I've even tried running the car while on the lift to simulate driving. So now, there not any codes or check engine light on so I'm thinking because the car can't be drove, it's the reason that the car won't set a code or turn on the check engine light. After replacing it, the car now runs just a very little bit better, but still won't run long enough to drive. So after more diagnosing, it indicated low fuel pressure from the High Pressure Fuel Pump. After replacing the sensor nothing changed & the car still runs just as bad as it was running before replacing the parts. Then doing more diagnosing the reason the car still runs so bad, a crankshaft Position sensor indicated to be bad. After replacing all the timing chains & related components, the car run exactly the same but the codes went away. The car started running extremely bad and had codes that indicated timing issues. I have a 2011 3.6l Automatic w/153,000 miles on it.
