1. I appraise houses - I cover a lot of territory - put roughly 6-1200 kms on it every other day.
2. The oil looks clear, not sludgy at all.
3. Not a lot of smoke, just noticed it the other morning. And only lasts a couple of seconds - not long at all.
4. Drives fine....on the most part. Just had the engine light come on yesterday.
5. It was a shop that re-built it...warranty was for 50,000 kms, and now they won't even return my calls.
6. The coolant reservoir has a hole - just replaced that...so no worries about any mixing...
I'm replacing the PCV valve tomorrow when it comes in...took it to another mechanic and he didn't see any leaks anywhere - he's going to do a compression test and check the spark plugs to see if there's a limited issue before taking it all apart.
Now, for the main answer - no, I don't live under a rock...I just don't have a lot of time to be on the internet searching things out....I had a few minutes this afternoon, thought I'd google my issue and this site came up.
Thanks guys...I'll have them check about the head gasket...I appreciate the help.
