Mystery slow leak, thermostat housing?
Hey all, I've recently have been dealing with some strange issues. A month ago my r53 smelled incredibly hot (along with the cel and eml light being on which has been coming on here and there prior, so much so I was sure it was going to blow up on my way home. Got it to a shop and they said I was low on coolant, but they said it was due to a bad pcv valve.. (hmm)
Fast forward to two weeks ago, I was leaving to run errands and I had two pretty sizable puffs of white smoke come out of the tailpipe and it left residue on my window that made me have to use the rear wiper. A week after, I was out doing errands again and both lights came on. Smelled coolant a little bit, then when coming to a stop light on the way home, I noticed a trail of white smoke trail up to the front of the car from the back. I took it back to the same shop and he said he ran a combustion test three times and it came back okay. He told me just because it didn't do it for him doesn't mean it won't, drive it and keep an eye on it.
Thoughts? Car seems to run just fine and did prior. Ran across something about a bad thermostat housing, could that be it even though my temp gauge never moved from center??
