Can you determine the cause of this ?
« on: Jul 25, 2009, 05:12:11 PM »
Its very hard to tell what went wrong but I can say it went wrong in a big way.  This is pics from today when I tore down Jimbos 22R.  Poor thing had 20 miles on it.  Lesson learned on why to have machine shops balance and match rods and crank.  I cant be sure if it spun a bearing or a cap came loose.  I didnt find the second nut for #3 cap so it could have backed off or ripped off.  I didnt think it would go this fast but I didnt think it would last long either.  Shame since I spent so much time on it.  Not if it was just wishful thinking or just wanting to help jimbo out and get it done.
I do have a new engine sitting at a yard waiting for me. Well almost new. It has under 10k on it.  Everything is on it as well so I only have to do minor parts swapping for smog.

judging from the main bearing i would guess the new bearings were not the same size of the crank,  maybe the crank wasnt turned

otherwise i would say there was no pre lube put on the bearings when they were installed

were the oil port plugs removed from the crank before it was boiled out??

if not the oiling holes were probably plugged up

My guess would be the rod bolts were not changed and they were over stretched, that is what usually causes catastrophic failure of a rod. Always cheep insurance to replace the rod bolts.

I agree. It could have been all of the above listed. As per Jim's story, it didnt' take long for this to happen. Was plasti-guage used? Were the oil ports blown out?

I have a 88 22re block, crank, rods, 100 bucks. plus shipping! ready to run with .20 pistons. no pistons though. Rods have ARP studs in em.

I would say the cap came off, low torque or bad bearing gap. Nice carnage though
If you see it, its for sale.

To be honest I cant remember if jim said it was hot tanked or not.  He got it off some friend of engbldr.  I am sure it was boiled but remember this block sat out in the weather for a while before I got it put together.  It deff was due to lack of oil the best I can tell. 
I spent 2 days doing prep work on this engine before putting it together.  Heck nothing was prepped so if I didnt get 100% prep perfect then it very well could have been my fault.  I will say its hard for me to do things half arsed and this engine was that from the beginning.  Not knowing the history of the parts which were going in the engine made things very difficult.

At least I have another engine which has less then 10k for it.  Dont really have the time to go pick it up or throw it in.  I have to pull a Dodge ram50 engine tomorrow and see if its repairable.  So by next week I should get back to this truck and put the interior back together as well as remove the 1st gen bed thats on it.  Truck needs a lot of work but I think if I get a few dings fixed and a fender.  Add some paint it might be worth having around.

Every R series I've seen that has a spun rod loses the #3 first....  I'd say the oil pump wasn't doing much or there was a clogged passage.  Either way it was starved for oil, I almost wonder if the bearings got put in backwards, that'd do it but looking at the mains it was oil starved at best.

Jim had to have the truck out of his parents place and with the engine done he just signed it over to me.  Now its my mess and I am not sure what to do with it.

Any word from Jim yet on how he's doing? Anyone looking after his wife while he's gone? Maybe she should start a "how Jims doing" thread here.
