Does an LT1 have a PCV valve ??

I went to replace my "PVC" and it looks like a hallow 90 degree fitting. No check ball, no spring, no nada. Is this correct or did the goodies inside take a walk? The large vacuum line goes to the TB so maybe that controls it.........

My car is a 92, yours might be a different year, but mine does run to the TB not just an intake fitting.

Mine is a 92 and I just walked outside popped the hood removed the drivers side fuel rail cover and the PCV is in the middle at the bottom and the hose coming out of it is U shaped. I dont think you are looking in the right spot my friend. I think you must be looking on the pass side. I made the same mistake too. The pcv does not go to the TB..It goes right back into the intake. That hose on the pass side is not your pcv

OK, you got me off the couch

On my 92 the passenger side valve cover has 2 holes. 1 you unscrew the cap and pour oil in, 2 has a rubber gromet with what I thought was a PCV valve and a hose that runs underneath the fuelrail cover and plugs into the TB. Underneath the fuelrail cover on the driverside, one U shaped hose and a long line that runs to the brake booster to supply vacuum.
