Re: Need expert engine builders advice (long)

Yeah the machine shop screwed up my crank. None of the journals were even cose to the same size even after they supposedly ground it. I take it to another guy now who does awsome work. Got over 1000 on the new motor and its doing real good so far even though my trans is now toast.

Re: Need expert engine builders advice (long)

When priming the engine I usually leave the valve covers off and see if I get oil to all the rockers before I install the motor. I re-prime the engine once in to fill the oil filters/lines. Now if you use a homemade drill thingy it might not prime the engine right. Think the distributor has some oil passages on it and if it isn't in there it won't transfer oil to the top of the engine. Can anyone verify if this is true?

Now just because oil pressure shows at the back of the block. Doesn't mean the oil is primed totally. That is why I wait to see the oil on rockers. Figure that is the longest path travelled.

Yeha thats a good thonmg to do. Tahts how I did mine also. JER I have no idea when my trans will be done. Im going to try to pop it out tomorrow night but I never can get anyone to help me. Well see what happens. Hopefully I can have it back in by Saturday night but at this point I highly doubt it.

Re: Need expert engine builders advice (long)

While not being completely trashed those main bearings are damaged. Clearances wrong, crank ground wrong (out of round/tapered journals), main bore out of alignment, crank run out too high, or lack of lube could have caused it. Pick one or all of them as one/all of them can and will cause the damage I saw in the pics.

FWIW dept:

Just sticking a "rod" of some type in a drill to turn the oil pump does not completely prime a 4.3, SBC, or BBC due to the way the oil passages in the block are cast. You must have the tool that looks like a distributor or cut up an old distributor and grind the gear off that engages the cam gear or your priming efforts are wasted due to a HUGE internal oil leak with just a rod turning the pump. Dont take my word for it just use the "rod" method and shine a flashlight down the hole where the distributor goes while youre turning the pump so you can see all the oil for the lifter galley getting dumped right back in the pan.

FWIW dept II:

The oil pump turns 1/2 the speed of the crank so as long as you arent spinning it 10k RPM you wont hurt anything. Youre average 3/8" or 1/2" drill is fine for the job but using a 20k RPM die grinder or something similarly fast is not.
