Dang it, I knew we should have pulled the heads last night!
(I really thought Donna was joking when she asked if I would be there until midnight...again 
) The book should give you the install procedure, Start with the last bolt (IDI has 16 per head) and work backward. Crack them loose, second time take em out a bit more, third time remove 'em.

What Log Book????
Good god man, did you type all that or cut & paste? My chilton's book says the same things. It also says not to lift the heads by yourself. Use a hoist or "intern"

heads are heavy and there is a "suction" to the block. You are strong, you will do fine ....(any history of hernias?
)
Get it on a stand and use the lift to pop the head.

What he said.
I would say it's "blowed up real good." Well The block will buy you a few Egg Mc Muffins.

Scott if you have an International dealer near you. Get this book International T444E Diesel Engine Service Manual. It covers everything you need to know about that engine.
Good luck man.

What Log Book????
Got an International dealer about 10 minutes away. I would have pulled the heads tonite but I can't find a HD stand. Nobody I know & none of the stores around here have 'em. I dont want to sit it on the floor. I gotta run a load of cars to NC tomorrow so it will have to wait til the weekend.

sweet im going to be around this weekend.
and just because a pushrod is bent does not ALWAYS mean the cylinder head is trashed, i have actually had 4 bent pushrods and no block, bottom end, cylinder head, valve or any damage other then the pushrods. what ever is the weakest point at the time of failure is the failure item, that being said the ball can always bounce into the other court, and there could be a failure in the cylinder head.

who cares? It's foundry scrap. Worried it's going to scratch the garage floor?

What Log Book????
I don't give a crap about the block, I got a 3 & 5yr old that play around in the garage near my stuff despite numerous beatings & being told to stay away. I can't have it fall or roll over on one of them. Plus I'm a fat ******* & I ain't sitting on the damn floor to work on this POS.
