After this weekend im planning on pulling my motor and rebuilding it the bottem end is making lots of noises. While its out im going to straighten out some crap under the hood and was thinking about getting rid of the oil cooler lines and just capping them off and the oil filter relocator. i dont really feel a need for an oil cooler. in my 2wd truck i didnt have one and all the GN's i work on when the lines start to get all naste and leak we just remove them and not run an oil cooler. i dont see any difference from having it.
what do you guys think. is there really a difference in oil life/engine life when you have an oil cooler? or is it just one of those things that people over think? (PS alots of searching no real answer)

Re: REMOVING oil cooler

I'm one to err on the side of conservative. The cooler you can run an engine, the better off you'll be. For what its worth, I don't feel there is that much room saved, or an increase in looks, or really anything at all gained by removing the oil cooler lines. They're smooshed up in the front under the airbox where you really can't tell if they are there or not. I'd leave em, or if you really wanted to, change to braided and make it all look purdy.

Re: REMOVING oil cooler

just relocate the oil cooler and filter under the truck. and cooler is better, especially since your oil absorbs a lot of heat.

Re: REMOVING oil cooler

Cooler oil is not necessarily better, especially with high quality synthetic oils such as Royal Purple or Redline. "Cold" oil is very bad on an engine, temps below 170 deg case significant wear on engine internals.

I think the reason GM used an oil cooler is because they knew the "average" person would try to use non-synthetic oil and go 10k miles between oil changes. Heat is a factor in causing engine oil breakdown, which causes the oil to thicken (not good for a turbo vehicle). By taking out some of the heat I think they were hoping for fewer warranty claims.

If you are using a good synthetic oil, and change your oil on a recommended schedule I say ditch the cooler if you choose.

Keep in mind you can't just "cap" off the external cooler at the remote oil filter block on our trucks, you will stop the oil from flowing. You can either loop the lines together coming out of the filter block to the cooler, or get a different remote filter block from a truck that doesn't use an oil cooler. The "loop" is internal in the casting on those models.
