Hi Guys,
I have a 93 model g10 installed in mybuggy. previously it had a weber 32/36 installed but have since swapped to a TBI setup.

Ever since i swapped intake manifolds and added the TB unit, i have had a massive smoke problem out the exhaust at mid/high RPM and smoke coming out of the breather/catch can attached to the valve cover. I did find (after having run the engine for ~15 minutes) that the PCV was stuck closed, so i replaced it but am still getting a ton of smoke. I have only run the engine maybe 10 minutes since replacing the PCV.

So, did my faulty PCV leave a bunch of oil in the cylinders and it's just now burning off? Could i pop the plugs out and peek in there with a light and see the deposited oil if that were the case? The PCV does not connect to the air cleaner assembly as it sits.

I did let the buggy sit ever since new years, could i possibly have a stuck oil ring? My compression readings were 180 175 180.

any advice would be greatly appreciated, as we have a huge ride planned for next weekend. :(

also i am running a summit external inline pump that maxes out at 45psi. i understand the TB has a built in FPR - but is it getting overwhelmed by the pump?

The TBI fuel is supposed to be 11psi. And the regulator and return lines probably aren't big enough to let past enough fuel.

idle pressure is 11psi, but key on engine off spec is up to 32psi.

if i toss an adjustable FPR on there and dial the pump back to 32psi heading into the TB, then the FPR in the TB can regulate from there and keep it at a nominal rate, yes?
