This is a non Turbo 850 GLT with 416 K on her.
I was just going onto the highway the other day and as I accelerated the car started to shunt/jerk.
Thought it might be some post winter moisture in fuel or lines and added some stabilizer and
after a couple minutes it ran fine. Next day noticed oil pool when leaving parking space and smelled
burning oil after a bit. Investigation showed oil leaking in engine particularly down right side in distributor area. Had to change oil anyway so put car up and degreased oily areas, changed oil & filter, removed the plate behind oil cap (cylinder plate?) as there was evidence of some oil leakage around bottom of oil refill opening. There was some oil pooling in depressions under the plate. Checked around PCV valve and found a small hole in hose to PCV valve and replaced hose.
Started engine up and after a minute or 2 got oil seepage again... appeared to be coming out of seal behind distributor.(got little puffs of oil smoke seeping from this area. Difficult to tell exactly. My question is: is this the front or rear camshaft seal ? (I cannot find a part listed as distributor shaft seal) I am also going to replace the PCV valve and the oil filter cap gasket. I have not replaced the Distributor cap and rotor in a very long time and figure that I will do that also. Is The flame trap something I should consider replacing and is it hard to find / get at? Where exactly.

I have been reading a lot of posts and don't think that I have a main seal issue as the leak appears to be much higher on the motor.
So I need to know which camshaft seal it is (front/rear) and if I should replace / check the flame trap wherever it is,,, also any other suggestions while I'm at it?
Thanks
