L98 Oil Cooler
I am wondering if anyone knows where I can source a factory L98 oil cooler, or if anyone has one. Could I just run it as is without the cooler? I am wondering how mandatory it is on the L98. The machinist strongly suggested replacing it because there was so much crap in the oil passages and the motor that he was leery of reusing the cooler. I would replace it but I don't want to get into replacing the whole system with an aftermarket one. I could try cleaning it but don't want to run the chance of one small piece ruining the whole build.
Dealership is out of the question, they say its discontinued. |
Is the oil cooler in the side tank of the radiator or does it sit in front? All of my illustrations show it in the side tank.
It also shows the cooler hoses as just bulk rubber hose, wouldn't be too difficult just to install an aftermarket cooler in front of the radiator/condensor to bypass the original. |
It is really not needed but it does help somewhat. go with a aftermarket air cooler if need be. Or get a bigger pan and 180 stat. May need the oil filter adapter if you take the cooler off i believe.

Ok so I could get away with not running it.
Stevoone, the factory cooler is basically running coolant to an adapter that the oil filter screws into. So its using the coolant in the radiator to keep the oil cool by running it through the adapter. Similar concept to a heater core, except it cooling instead of heating. Deadtrend did you mean get like a 6 qt pan and run a 180 stat to keep the oil cool without an oil cooler setup? Didn't think you could run a bigger pan with a third gen. I will see how the cooler looks with brake cleaner. If it looks like its out of the question then I'll look into getting an oil cooler for it to put in front of the condenser. I'm guessing I'll need more oil in the system if I run an aftermarket oil cooler due to oil being run out of the motor? Forgive the seemingly stupidity of the question but I'm more used to factory setups. |
FWIW I seem to remember the LT1 oil cooler being more detrimental than anything else.

Good idea, pretty bad design... Although the factory trans coolers are decent - if you get your car's water temp down below 200 degrees.
You can get a good aftermarket cooler for $100 or so that would actually do a lot better job than the factory item could ever do. |

Plenty of good old SBCs were beaten on without an oil cooler, and it wasn't too detrimental to their health. When I built the L98 for my old Monte, I just installed the regular adapter and screwed on an oil filter. The first L69 in my '85 SS had almost 200K hard miles with no oil cooler, and it was still clean inside. Regular oil changes, keeping revs to a decent rpm, and good coolant temps will keep your engine alive just fine.

You will be fine. Not all Chevy V8's came with an oil cooler, It was an extra. If it was absolutely necessary they would have all come with it
|
I run a modine version in the l98 formula...coupled w/mobil uno...temp gauge never moves past 180 (and yes the gauge works..lol)
