1G PCV System Question - Oil Cap Leak

[Chad hiner]

I recently purchased a 90 eagle talon tsi awd. The pcv was deleted but in cause and effect although adding a catch can the pressure in my cc is high enough to cause leak through the oil cap screw. Although replacing the oil cap with a different model that doesn't have the screw on top would leave me trapping cc pressure. So what would be my best layout for venting

You can put a oil cap that has a 10an fitting on it, in place of the stock oil cap then vent it to the can. You can also run the vent of the valve cover to the catch can.

You can also run it from the rear balance shaft inspection bolt. They sell a fitting for it

Would i have to make a custom oil cap with a ventable fitting to run to oil catch?

Yes. They were available thru a freelacer on here at one time.

I would also be concerned about excessive crankcase pressure just fyi.
You can vent from the block as @TK's9d2TSi pointed out too. You have a few options.
