S & J offers a high quality rebuild. That is one part of the equation. If
you have blown an engine, and there is debris in the oil system, it
behooves you to remove all microscopic traces of it, or you will be
replacing the new engine in short order. This includes everything
downstream from the oil pump. Cooler, lines, etc. Also, any antifreeze
remaining in the intake manifold that makes it's way into the oil will have
the same result. Just a few words from someone who has seen more than his
share of the results of not taking care of stuff like this.

Kerry,

As soon as learn to perambulate on my new bionic left knee I will head down the workshop, cut open the OEM oil cooler and OEM trans
cooler and present facts and photographs that will enable "very, very wise and experienced GMCers" if removing the OEM transmission
and oil coolers is necessary or not.

Keep in mind that at one time very, very, wise and experienced men believed the world was flat and in contemporary times there are
people that believe the Moon landings were filmed in Arizona.

Leith, at the risk of igniting the 'oil flow' wars again. I chose NOT to use oil cooler in the radiator after I lost my engine.
Some say the oil filter will catch any debris before it goes back to the engine and they are probably right. HOWEVER, a very, very
wise and experienced GMCer recommended going to a separate cooler and given the relatively low price and peace of mind, I went with
his suggestion. I ended up with a fan forced unit that mounts in front of the right front wheel liner. The fan is on an integral
thermostatic switch. An added advantage is removing that source of heat from the radiator.

I can't comment on the S&J engine but have a LOT of respect for some of those who recommend them.

Which external oil cooler did you use? I am looking to install one on my GMC as I've been running without an oil cooler for a while now (long story for another time) and I think it would be good to have an oil cooler again if I want to drive in mountains or pull a towd, both of which I don't do now.
