hope u guy can help I put together a nos 440 shot block 1978 vintage that had no crank, I had a cast crank so I turned it 10 10 and put it in. I ran it for a while maybe a half hour and took it for a spin
oil pressure slowly degraded down to 0 at a idle then got main bearing knock
after finding a lot of crap in the oil I pulled the motor and found the 4 and 6 rod and the thrust wiped
not spun no heat color just down to the copper and ground up but I could not find any reason for it.
caught it just in time no crank damage.so I cleaned up the mess thru the block in the dishwasher polished the crank checked all the oil galleys in the block and crank 100 times and everything looked ok. so I put it back together I had 2.5 on the mains and 2 on the rods and 4 on the end play. I fired it back up and had 80lbs cold with 20w 50 and 35 to 40 at a hot idle maxing out at 70 lbs when the revs come up.
then one of the hyd lifters starting hammering away so I got paranoid because the first time I had a loud lifter right out of the gun. so I drained the oil and I found metal again not so bad as before but at the end of the drain and in the filter it looked like silver fence paint.
any ideas? do you think this Christine motor is going south again? I could spin the crank by hand before I put the rods in, real easy and smooth, after I loaded the pistons in I could spin the motor with my finger on the wrench real nice.no oil galleys were blocked I put my brush in from on end to the other on every one and blew them out with air.all the oil galley plugs are in no leaks I used good assy lube and I primed the motor with a drill both times and I spun the motor over with the starter and no plugs before I started it until the oil came up.

Did you look at the cam bearings?

the looked fine to me
the first time the cam went in it was snug but i could spin it by hand the second time it spun a with little less drag.i didn't notice anything wrong
the first time around i had a loud lifter right away
the second time i did not get and lifter noise until
i ran the motor for a long time that's what scaring me.

" silver fence paint"....means you need to pull it back out and apart.

I'd suggest enlisting some experienced help from your machinist or a builder on the re-build.

good luck...

may be your right i only got 30 years into it

very lite you had to look hard for it

must be haunted!

I'm thinking the block may have a cracked in the oil galley area when it heats up gets worse

well first let me say I know what you mean.
I am just a guy with a problem motor who just threw it out to his peers to see what they thought
because at this point I am a little beside my self with the problem.
I have very capable people in my corner that think the whole thing is a little crazy too.
every thing was measured and remeasured
the mains were 2.5 rods were 2 the end play was 4
all the component were new except the crank and it had a fresh cut. 10 10
the amount of force it took to spin the crank with out the rods was unmeasureable and I could spin the complete short block with 1 finger on the wrench. it was very very smooth. the motor had 80 lbs of oil pressure on the stand with the drill. so with all that being said I just thought I would kick it around out there no big deal.
Phil Miller in Haverhill Mass is my long time friend and my machinist so if I have to take it back out I will bring it down to Phil and we will look at it together.

well the oil pressure held it's own this time aroun it's just the junk in the pan thats bothering me there wasn't much but there should not be any! i drained the oil in a black pan then dumped it out and on the bottem of the pan i could see some specs of bebris and silver very little but still

Your sure the oil pump it self is in good working order? Some of the silver glitter stuff can be piston skirt wear, on a new engine, bronze bushing wearing in, flakes from cam bearing installation. At first I was wondering if a cam bearing had spun enough to block the hole. Did you put anti seize on the head bolts or main studs? Some do and it would show up as described. Not sure if you had a new oil pan or used with a baffle. sludge gets caught up under the lip of the hp pans and can let go and plug up some holes. Same with a pick up screen if used. Also if you had used heads, and they were on one way, the oil holes to the top end on the opisite side gets gunked up. Always have to clean that very good. I am just thinking out load so to say. Could have an internal crack as someone said. Lifter is one things, a perfect mic'ed bottom end killing bearings is another all together.

TURTURE AS IN PAIN
I CANT SPELL EITHER

everything was very clean and new both times
516 heads with 2.14 1.81 valves all done up

everything oiled nicely when i primed the motor with the drill i had 80 lbs

i know thats why i am loseing it!
i changed pumps the the second time with a blueprinted hv from precision "ported polished and moly dryfilm coated gears"

thanks for kicking it around with me!
