Mike, that sucks. Maybe you can find a good used short block and piece it together as cheap as possible, or maybe a cheap used engine to get you by until you can rebuild the other. Just a thought.

Well my history shows that I don't do anything cheap. I'll wait until I can get it done right. Of course now comes the nasty thoughts of increasing performance /forums/images/icons/wink.gif, maybe change it into a 427......./forums/images/icons/laugh.gif

Like they say all one needs is money. Got any????/forums/images/icons/laugh.gif

try using some restore in your engine oil......for now.

after about 500 miles......recheck your spark plugs and oil
intrusion should be reduced....

Restore is sold at any auto parts store Autozone or Kragen.

it is about 8-10 bucks for a v8

it works too.

lemme know when ya wanna pull that engine out......just make sure ya got an engine stand.....

We can get the cherry picker and pop the little SOB out...
