Somehow lost 2 1/2 quarts of oil. Now i have a big clank noise and it turns off by itself. new short block?

 

might be. theres obviously an internal problem for u to be burning that much oil. i had the same problem a few years ago and ended up with 2 spun bearings. it wasnt a subbie but it started burning oil just like urs.

 

big clanking= rod bearings?
how resistant is the sti crank?

You need to have the mad scientist pull apart the block and replace the piston rings you fried!

 

your always quoting F&F, Rican

 

STI cranks are known for 600whp. But not knowing how many miles are on it...

 

anybody i can take my motor to to get it checked out? 93000 miles. Anybody in the sarasota area that can rebuild my bottom end the right way or should i just save up and buy a pre assembled unit.

 

My shop doors dont open until next month unfortunately. I am located in Sarasota tho. If you want I can PM you a price on a nice built block

 

yeah get a price on a block. if u hear a hard knocking on the bottom end is a spun bearing. so weather if its a rod or main bearing, ull need that new block either way.

 

If it spun a bearing then most likely the crank is scarred so byour better off buying a new one. People have made 700 whp+ on the stock crank. It is forged. If your not looking for more then 400 whp then you can just get a new shortblock for about $1700 from various vendors. All depends how far you are trying to go and how deep your pockets are.
