Blew my rear main seal twice in two days!
#1
Hey guys there's something definitely wrong with my pcv routing with the tvs2300.. i will try to explain what i had and have the best i can i can't draw diagrams pretty well..
so first setup was
blower inlet port to catch can, catch can to a T junction going to both driver and passenger side valve covers and a breather on the oil fill. this setup worked great until i started running 14 psi
replaced the rear main seal then changed things around a little bit but still blew it after 1 wot run from 0-130
current setup
blower inlet port to catch can, catch can to driver side. passenger side inlet is capped with a breather on the oil fill.
3rd times a charm lets hope so
a friend of mine told me to remove the catch can.. run a line from the blower to the driver side, and a line from the passenger side to the intake tube, leaving the breather on the oil fill.
thanks in advance

That's strange, the rear main is usually not the place where crank pressure relieves itself. I've blown out valve cover gaskets before, and generally the oil dipstick will push out of the tube as well.

This is pretty important. It might be a little bit deceiving, because you're meant to push the seal over the end of the crank. They come with a plastic insert to keep the seal expanded to prevent the seal from collapsing while you push it on. The seal faces inward so that any pressure or oil can't push the seal outward and leak.

My first thoughts as well.
