how did the plugs look?

 

no sign of oil what so ever???

 

exactly..... the oil is going somewhere...but where? </P>


I have a brand new 2001 cobra engine about 20 ft from my desk if ya want it $5000</P>

 

go to www.stangnet.com go to forums look under SVT. go down to prople who got screw with long tubes look on that list of links that guy give me check it out and get back to me

 

i dont know what to tell ya, the first thing I would do is take them off and replace them with stock manifolds or a different header and see what happens, if that doesn't work then start looking into more extensive repairs, like rebuilding....if they did what people are claiming where the cyl walls are scratched, then you'll just have to rebuild it then you'll be fine</P><edited><editID>Black Horse</editID><editDate>38002.0622685185</editDate></edited>
