Anyone know how much it would cost to overhaul a 98 LS1 i could get one pretty cheap but it has 140k way more then what my 98z has i have like 92k on the motor. It happened when i started it. it was running ruff like the coil were'nt firing right turned off the car started it again same thing running ruff go to look under the hood all i seen before i opened the hood was a long trail of oil coming from under the car. Thing is i think the car will still run if i tried to start it. Pretty weird. So i would rather have a knock then a hole in the side of the block.

So i found a 02 WS6 motor with 25k has the ls6 block long block i'm looking to get. also never used nos on the motor hardly took it drag racing only twice since i owned it. and last time i went was over a year ago. Also engine has 93k.
