Blue smoke from tailpipe fixed...from oil pan gasket repair?
Hello all. Just posting and curious if anyone else has ever had this happen:
So my 2005 Camry has 180,000 miles on it now. At about 150,000-165,000 miles, somewhere in there, the car would, on a cold start in the morning, have some blue smoke that would come out of the tailpipe for a about 10-15 seconds. I've always understood this to be valve seals that needed to be replaced on any other car I have owned. It's not a fun job, and any car I've done the fix has been tedious but does fix the problem, so it's been reinforced in my mind that is the fix and the problem. So, this car being no different, I told me wife I would get to it eventually, and just not to worry about it, the car will keep on going for some time. Well, about a month ago I noticed oil actually dripping onto the driveway, so I had to get under it and see what was wrong, and that's when I saw the oil pan leak, which I did notice some time ago, but it was mild, was now enough of a problem to be dripping after parking it every night. I looked it up, and for my 4 cylinder car, it's a breeze. I did the repair (which I noted in a different post) and 'voila' my oil leak is fixed. But, the funny thing is....the tailpipe blue smoke in the morning problem also went away. At first I thought this was just a coincidence, but I've now put on about 2500 miles in the last two weeks, and it is definitely gone.
So my question is: Does an oil pan leak cause enough of a vacuum pull or leak to cause some oil to pull past the valve guide and simulate a worn valve seals? If so, this was a great fix, and I wish I had done it a long time ago. Has anyone else every seen this?
