hello, I recently was driving through town in my trusty 1996 cobra and spotted a real nice 2000 model black GT with 18inch cobra R's with nitto drag radials forsale. so like any mustang guy I pulled in lot to check it out. its income tax time and Ive got that itch for a change. and due to this mustang having drag radials on it I knew there had to be go fast goodies. also intercooler sticking out under the front spoiler was give away. car had 134k miles with a price tag at 7k. the owner was near due to fact he own a business close by and was kind enough to pop hood and show me the shiney new vortec sc pushing 6psi with stock block. car was all stock other than supercharger and injectors. was real interested in car until he cranked it and car sounded good but noticed on drivers valve cover he had a chrome filter that had what appeared to be blowby coming out of it. and I noticed it seemed to be blowing oil from the chrome filter due to it was all oily and oil was present around the area of the filter and some blown up on fire wall. should this be something to worry about? is this blow by from bad rings or worn out block? sorry for wall of text but just dont wonna invest in a car, just to have to rebuild the block. there wasnt any knocking at all just steamy like white air coming from the valve cover filter. thanks for any imput.
