I’m sorry for the long story but it has to be told so you knew where I am coming from. I have put the question first but the story tells what Toyota is trying to pull. Everything I read on line tells me that overfilling an oil tank can lead to valve stem seal damage (the problem they want to charge me $2,000 to fix) or other problems. That it’s just as bad or worse than driving with no oil. I’m looking to see if anyone here has ever had this issue or can tell me from a mechanical view if I’m way off base. I have a feeling I’m going to have to take Toyota to court to get my car back in order. It was bad enough my water pump blew a month before I found out about the oil burning recall, which I also read that the water pump can be damaged from burning oil. I honestly don’t know where to turn…can anyone tell me what kind of damage can be done to a car driving with an overfilled tank for 3 and a half weeks and possibly with the cap loose or off for that entire time?
I have a 2007 Toyota Camry, 4 cylinder…I brought the car in for the oil consumption test…they filled my oil and sealed it, told me I needed two new spark plugs…my son drove the car off the lot and it stalled 3 times, he brought it back. They told him we needed a new ignition coil, I told them not to touch it I’ll have my mechanic look at it, and what a coincidence that it all of a sudden had that problem. They brought the car back into their shop and 15 minutes later, the car was running fine!! Okay, so I do the allotted driving, bring the car back and it fails the oil consumption test, they keep it to do the repair. They repair the pistons and the piston rings (still trying to charge me for the spark plugs that could have been damaged from me burning oil for so long but that’s besides the fact). The said they are only allowed to fix what toyota says for the recall and that is the piston and piston rings. I drive my car for 3 weeks…it starts to blow blue smoke…My mechanic doesn’t even look under the hood he sees by the tailpipe that there is oil there. Tells me Toyota didn’t fix it. Oh before I bring it back to Toyota, my son is driving it and it sounds like crap so he stops and opens the hood to find the oil cap is not on the tank. WHAT!!!
Bring it to Toyota…the mechanic has it for 5 minutes calls me back and asks, in a very concerned voice, if I filled the oil since it was there and have I been driving with the oil cap off. I say no to both because I hadn’t talked to my son yet. The oil tank was overfilled by the Toyota service department and the cap either left on loosely or not at all. All of a sudden the fact that it was driven with an overfilled tank and the cap off isn’t a big deal because they did it!!!1
So they tell me it’s my valve seals and it will be $2,000+ to fix it. I’m like hell no!!! Another coincidence??? I called Toyota corporate and start an official case against the dealership…they send it to the GM. The GM says he wants me to drive the car another 1,000 miles…I don’t know why but I tell them it’s blowing a lot of smoke and making funny noise…I don’t feel safe. They have me bring the car back in for them to check…(I don’t trust them but I bring it in) So they call me all nicely and say yes the oil was overfilled, so they drained it for me (REALLY!!!) they at first can’t hear the noise, then hear the noise and say it’s the oil pump but they checked everything and the oil pump is fine. They then tell me they still can’t see the blue smoke so they keep it overnight…call me the next day, see the blue smoke and tell me they are doing the oil consumption test again, I have to drive it for another 1,000 miles. I told them they overfilled the oil which could cause engine problems, let alone the valve stem seal damage they are telling me needs to be fixed. Mind you it wasn’t until the last day that they finally saw the smoke but quoted me valve stem seal damage (without ever looking at the valve stem seals). When I asked about all this they said that driving with the overfilled oil for that short amount of time couldn’t cause any damage let alone the valve stem seals.
THANK YOU for any help or guidance.
