yea i talked to those guys too. they have 2 low compression long blocks they are trying to see. 800 for both. i thought maybe buy them just for parts. idk what to do. i need to pull my head off and make sure everything in there still looks ok. if so would the 2 motors be a bad idea? what u guys think?schanne wrote:How can you have the company's check for compression and do a leak down when it's just a long block? I'm in the same boat as you miss 180 with my motor. I found a redtop long block from jdm of miami for 700. Blktop is 800... I have purchased parts from them in the past with no problems at all. But motors seem to be a different story!
Do you mean two wore out long blocks or two turbo long blocks?Miss 180 wrote:yea i talked to those guys too. they have 2 low compression long blocks they are trying to see. 800 for both.
Look for bent valves, and dents or gouges in the combustion chambers, (in case a piston exploded,or a connecting rod came apart, but I doubt it). On the block, look for anything out of the ordinary. Like a piston rocked at an angle, or a piston that has rotated in the bore.Miss 180 wrote:this is a noob question. when i pull the head off what exactly am i looking for? like metal or broken parts or what not......?
