    Alright I bought a motor knowing that it had a slight knock. I got a really good deal on it. Any way I took it apart and of course it spun a bearing. It wasn't anything bad, it didn't mess up the crank or the rod.

    The question remains, if I check the clearances on the crank and it is still good and not fubar'd. Am I good to buy new bearings(that are the right size) and replace them. Or do I "need" to get it machined. The motor is just a d15 for the honda and nothing performance is ever going to come of it. The motor just had a new timing belt, new water pump, etc. The compression is good. I really rather not junk it.

    The right way: Mic it, plastigage it.. And throw some correct bearings in it.

    The almost right way: buy some OEM fucking bearings and be done with it.

    I think I'll go with the almost right way. the motor had lower miles on it anyway. And if it goes, the motor was only had for about 60 bucks.

    If you go the almost right way, get thicker oil.

    Put a new bearing on it and drive it. If it dies you are not out that much cash.

    that kinda is the plan. lol. but all the bearings kinda look like they should probably be replaced. They are not bad but still kinda showing their age. we'll see how it goes.

    I did mine on the racecar with the motor and everything in just dropped the pan.
    Didnt fix the problem. I think I needed undersized bearings. But they were only $20 shipped from slowboyracing.com.
    But im just gonna rebuild the motor. Cuz its full of fail.

    the motor is sitting on its side on a work bench in our poll barn. it is going to go in the shitvic to get it going. I am matting it up to a vx tranny(really long gears) and basically going to try and build a mpg car. lol
