Now that its been mentioned, i noticed the oil pressure guage reads around 1 when at operating temp.
I dont disagree with the ihuh of getting the car inspected, however i am a quite handy DIYer. I found the harmonic balancer job not too hard on my 89 once i got the hang of it.

So... Guides and tensioner huh.. Full timing cover top to bottom must come off?

If this became a money pit id just sell it before i spend to much on it.
