Help! Advice needed!

[HighPSIRacing]

I just spent every penny I had rebuilding my motor and spun a bearing
I pulled everything, measured everything again, cleaned EVERYTHING again and replaced the bearings. Right after starting it I noticed a metal on metal slapping noise, I pulled the head (doh, there goes a 4 layer steel gasket) and sure enough the piston is slapping against the head. I'm being told I need to have my crank ($80) and rods ($48) machined. I don't have enough time to work on the car right now because of work, and I need the car for work!!! I'm being quoted appx. $800 for labor alone to pull the crank and re-install everything. Any advice welcome!

Did you get your crank machined prior or just put new bearings in?

Oookay, then. What's the rest of the story. What rods, what crank, what block, etc.

I have all my mods listed in my profile. No I haven't had the crank machined before, I was just being a cheap @$$ and put new bearings in. I'm just going to buy new rods and have the crank machined.

I dont understand how your pistons could be hitting the head? Unless you had the block decked so far that the pistons come up out of it...


I've also never heard of a crank needing to be "machined" . It seems to me like you need to do some further investigating into what the problem really is.

PS You can reuse that head gasket.

I spun a bearing and there was just enough play between the rod and the crank to hit the top of the piston against the head.

I was told by RRE, and a local company SRD that I cannot re-use the Mitsu 4 layer head gasket.

Okay, well unless the bearings spun so badly that they ate into the actual metal of the rods then you shouldnt need new rods. From what it looks like to me you can pick up another good crank and put new bearings in it and go with that.

As for the gasket, I have reused one and the car is fine. Especially if it wasnt in there very long I bet it'll be fine. But do what you want.
