My brother has a 99 with a cracked 53 block
. Motor runs fine, just leaks like a sieve when warmed up. We have found a 2001 bear block for a good price. Is there any reason we couldn't take all of the internal parts from his 1999 motor and put into the 2001 block? Is there any special tools or words of advice to do this? Where can we get a rebuild manual for the cummins? We haven't purchased the 01 block yet, but we're going to unless we are told differently. Thanks for the advice.
