Blown Engine

[dondi_m]

I need to know where to get a quality rebuilt engine for 1994 4x4 truck. Has a 22RE. Not sure if it's a long block or not. How do I tell?
I could re-build myself I guess, just limited on time. Is there anything I should be mindful of when replacing the engine?

Thanks in advance.

It's easy to tell the difference in a long block and a short block. A long block comes with crank and pistons/rods. A short block comes bare...just the block.

Usually a blown engine requires at least some pistons to be replaced and often the block and crank. I'm betting you will need a long block.

Okay.....boy do I feel stupid But that really clears up a few things. I thought there was a physical length difference.

Thanks again.

Anyone else have any suggestions as to "things to look out for"....

yeah DONT buy a motor from anyone who sells RECON brand motors. they are the biggest piles thats have been made. i delt with recon for 5 years and about 70 % of the motors that i sold for any forin car or truck came back

That's good to know, thanks. Any modifications I might want to consider while I have the engine out? Keep in mind I'm not building a hot rod....I just want it to run....to run well. I plan on changing out the clutch while I'm there. Anything else I should replace while the engine is out??

for your year of truck, id consider looking for a used low milage salvage yard engine.it would be complete waterpump,dist ect all on AND,you could probably hear it runand do compression test before you buy.otherwise go for a qualityrebuild,its better to spend a little extre here rather than fight a poor quality rebuild

First,
A long block comes assembled with the cam, head, block, pistons, crank, rods, timing set, and usually oilpan and valve cover.
A short block is only the bottom end, as in the block, crank, rods and pistons.
Both would come with an oil pump and maybe a water pump most likely unless it is a really cheap outfit or something.
As far as your rebuild, there are some companies out there with good reps, like engnbldr.com
I don't have any experience with purchasing one as I like to rebuild them myself.
For a solid stocker,
Make sure the block has been THOROUGHLY cleaned before and after machining. It should be bored and honed to fit each piston, not just all honed to one dimension if possible. Crank should be either reconditioned or new, with properly sized bearings. Rods should be reconditioned, and it's a good idea to use ARP rod bolts for extra insurance. The deck should be checked for flatness and resurfaced if necessary. Cast pistons are ok. A very good idea to have the whole assembly balanced. This lends to a smooth running engine and longer life.
The head should be totally rebuilt including pressure checking it, careful inspection for cracks, etc. Replacement heads are available if needed, also from engnbldr and others. You can re-use the intake valves if you want, but they are cheap so it's a good idea to buy new ones. Exhaust valves should be replaced, IMHO. Springs should also be replaced with new units. If the cam is in good shape, you can re-use that, but it's a good time to upgrade if you want a little more oomph. Make sure the springs match the cam. Get a good three angle valve job.
New oil pump, new water pump, new timing chain and gears, and new timing chain guides.
While you got it apart, it's a good time to replace the vacuum hoses and water hoses. Maybe clean out(or replace) the EGR valve if you have one, replace the fuel filter, replace the O2 sensor(should be done every 60K miles or so) possibly have the injectors cleaned and balanced, the list goes on. Depends what you want to spend.
Take some time to research reputable shops. It could easily make the difference between a 300 mile engine and a 300,000 mile engine.
That's what I would do, I'm sure there are other opinions.
(actually, I would do more performance oriented stuff as well, but thats another story )
Good luck

Thanks for the insight. This is all great info. I am going to take my time on this and do it right. I'll probably end up replacing a lot of stuff.
Thanks again for the tips.
