engine swap

[93hummer]

Thanks Mark, I may take you up on that, I need one more good one. I have been checking things out and a lot of little things are different between the 82 and 86, so I need to do the following:

1. change the oil pressure and water temp sending units (different between 82/86)
2. change water pump (because the old one is pretty crusty and I happen to have a new one on the shelf in my garage).
3. clean the donor engine, cause it is nasty!!
4. change the CDR valve and EGR hoses over (because the donor engine has some oil leaks in those areas... see number 3 above...)
5. purchase and install new crank pulley (two peice pulley with rubber center section to absorb harmonics).
6. purchase an oil pan gasket.... may be opening a can of worms, but I might as well inspect the bottom end while it is out.
7. swap over fuel lines to/from injection pump/fuel pump/fuel filter (different between 82/86)
8. Alternator brackets are slightly different, will definitely effect belt length, install the 86 bracket onto the 82 donor.

The goal of these changes is to have pretty much everything match up to the 86's stuff so that when I go to Napa for parts, I am not mixing and matching years for different things or trying to remember what got swapped over and what did not.

That's about it for now. The donor engine showed very little blowby and no bubbling or pressurization of the coolant, so it should be a pretty solid motor. even with 7 nonfunctional glow plugs, just a tiny shot of ether and it was running, and it hadn't been started in two years.
