2.3 stroker using oil

[HIGHPSI4]

I have 1300 miles on a rebuilt 6 bolt that is using a qt. of oil every 300 miles. Pulled the head and had oil in intake manifold. PCV and EGT are removed. Turbo is not using it and the pistons/rings are great. I have lots of carbon build up on the valves and head but the plugs are good and clean. Where can the oil be coming from? thanks

valve stem seals are one possibility. if they ae installed wrong it could be seeping into the combustion chamber which would explain the carbon build up. did you use o.e. stuff when you did the head?

Were the guides replaced?

Yea I got bronze guides from 'Engine Builder'. He has a site and a buisness.

My 2.4L long rod (same pistons as a 2.3L but bigger bore) didn't like having the PCV valve removed. It would burn oil at idle without it. Plumbed it back in and all is well. Another fellow with (swordfishgsx on here) had the same problem, he fixed it by getting a valve cover with -10 AN vents on it.

If it smokes at idle pop the oil cap loose and see if that stops it.
