The look on the guys face was priceless

So where's the E-N-G-I-l\ from the stick? And the X-hashes? And the 2 holes?

That's gonna' take 3+ qts extra to hit THAT stick. Then the crank is gonna' foam it up, and no pressure. Again.




:confused




Bob...

You ground it off, so they'd toast your motor? You slick dog.

When we dropped the pan here in Havasu, we never found the piece of dipstick...that's a mystery yet to be solved....:confused

Should have just put a new engine in, probably cheaper than all this rebuild stuff.

It would have been cheaper, but that would have taken all the fun out of life....

No idea right now where the .047 was found but I'll be sure to find out on Friday...that's the turnaround time from the machine shop that they sent the crank to.

I think that is too far to fix right no matter where it was found, and I will be getting a new crank...

I still can't believe it was that far out and I could not hear it....

Probably because its easier to hear loose rod bearings at the big end...those bang around pretty hard because of the reciprocation. The crank mains just turn so they do not actually knock. Sometimes with a spun bearing there might be a clicking or thumping noise. But the typical knocking or "rapping" sounds come from a "rod knocking". Tapping can be a rod bearing small end.. You can learn to tell the difference after hearing a few...

The usual way to spot loose mains is oil pressure that drops dramatically as it warms up. That tells you that the oil is being squirted out of the loose bearings instead of being forced to travel thru the passages as designed to reach the top end. The pressure sender being near the top of all the passages reads whats left of the oil pressure....The far end of the road. If there is'nt much pressure there that means its being lost inbetween somewhere and bearings are the #1 source.

The spec is for 5 bearings...
1 & 5 being a little a little looser being end bearings, while 2,3 & 4 are a bit tighter. Inners 001-.0025 and #5 is .0035 max service.
Production (new QC check) is much tighter.

I know there is a wide range of oversize bearings. If the crank has to be ground that much, there might be a bearing to match. You'll soon find out !
It won;t hurt a thing to be ground as long as its within service spec and the proper bearing is available. .0050 ain;t much, but its too much when you're trying to keep a tight tolerance thats supposed to hold hot oil.
