I am pulling stock 99 motor out of my T/A and just bought an 03 LS6 longblock. The new motor does NOT have ls6 valley cover. I have been reading non stop about what to do about the PCV system/conversion etc on the car. I am putting the F.A.S.T. 90/90 combo on the car at the same time. Some people are just plugging the back of the intake if i read it right and just putting breathers on the valve covers. Then people say that it will ruin seals etc. Then there is catch cans or something etc...In all honestly. If you were doing a swap like I am, what is the best/safest thing to do about this??? ANY help is appreciated! thanks in advance to everyone.

Did you check the block # to verify it really is a LS6 block? It seems odd someone would sell a LS6 block with the incorrect valley cover. Otherwise just buy a LS6 valley from your local dealer or call SDPC (sponsor here) for a price.

Put he LS6 valley cover on the the block and run the PCV system. If you want to add a catch can later it is very easy to do off the existing PCV system.
