Hey guys here is my back story. I built the car last year drove it all summer with zero issues. Spring time installed larger turbo and got it tuned. Lots of fun having a datsun with 327hp/288tq (I can post vids on that later
I drove it for a week before the tune and a week after with no issues. This past weekend I gave a friend a ride and had a oil burning smell when I got back. I previously had the oil catch can hooked up wrong from the pcv but I guess at stock boost it made no difference. Well the T on the side of the valve cover had a breather on it and it was dripping oil so I took it off and put a cap on it. This caused the dip stick to pop out and blow oil all over the engine exhaust and hood. So I ordered a new OCC to reinstal it the correct way from the valve cover to the can and down to the engine block. Well now explain this! Last night I went to drive the car from the garage where I installed the catch can at my to my dads house at the top of the road (less then a mile)... I got there just fine it made tons of power. When we arived there was smoke under the hood again, and we found another oil mess and the brand new catch can is FULL in the distance it took to drive up the hill, blew oil out the breather and all over the place again. Now mind you I didnt take a leisurely jaunt up the hill there was lots of boost but what the heck.
The mess it left out of the breather after a minute long drive
used a pen as a dip stick after looking into the can and seeing some reflection in the noticeable amount of oil it had in it
Ok so this is how it is routed. The front of the T on the drivers valve cover goes to the occ, the back of the T is Blocked off and the outlet of the can goes to the oil pan on the back drivers side of the block. The passenger side PCV now goes to the intake manifold
I am wondering if either A the oil catch can has to be higher then the valve cover and it is somehow just sucking the oil from the valve cover. I have heard the S13 valve covers do not have good baffling but that is 450cc of oil in less then a mile I would never be able to drive anywhere without a case of oil and rags around.
My other concern is maybe my turbo has a blown seal and it filling the valve cover somehow. Also maybe I have a bad piston ring that is building pressure in the valve cover. I just dont know. What tests should I run?
