so i searched around the site but i couldn't find any posts that ansured my Q. so

here is my problem i rebuilt my top end and fixed a Blown head gasket.
i used arp studs and cometic MLS HG, i have oversized valves and some bolt- ons. When i put it all together i was hitting what felt like fuel cut,but was not, at 3,000 rpm so i tightend some vacuum hoed the boost leaks. I think i blew out my turbo? but why, it was at stock psi (i did install a MBC) please help.

-the turbo was leaking from the feed line so i bought a new gasket and fixed it, now when i pull off the intake i notice a little oil..

please help i need it to run soon..

Thanks in advance,
Nick
