Hi All,
I have a 1968 Mustang Coupe with the 200ci. Pretty much stock engine other than a Pertronix and Coil, no other upgrade to any engine parts. The car is new to me, bought from a neighbor. They have records going back to the early 1980's, albeit sometimes they are just more of what was done rather than exact parts, etc.
Anyways, I'm having two main causes for concern:
1. Upon cold start, I'm getting some blue-ish smoke from the exhaust. It definitely has a "scent" to it like it's burning a little oil. The smoke seems to dissipate after getting warm, but there is still a smell.
2. Low oil pressure when braking primarily.
A few things to note - I'm using the standard "dummy" gauge for oil pressure now. I realize I need to put a mechanical gauge on there, and I've already ordered it. The dummy gauge goes almost to the low point until acceleration begins, then creeps back up. On straight roads with no stop and go, the dummy gauge goes back to the middle until braking occurs.
I completed a compression test today - dry test only, car was warmed 10 mins or so before completing. Compression seemed good on all cylinders:
Cyl 1 - 155
Cyl 2 - 170
Cyl 3 - 165
Cyl 4 - 165
Cyl 5 - 170
Cyl 6 - 170
Each spark plug had oil on it. I took photos, I'm hoping they come through.
Thoughts? Not sure what would also be causing the low oil pressure upon braking.
Cheers,
M
PS - I am literally brand new to the backyard mechanic thing. Extra patience and guidance is appreciated - you've guys have been a world of help to others. TIA!
