Is it ok to bypass a oil cooled on a 91 talon turbo?

Re: oil cooler
 

it is just a coolent oil cooler you can by pass it. I did not have mine hooked up on the talon for a long time till I put in the 90 set up

Re: oil cooler
 

I also don't have mine hooked up to the coolant lines.

EDIT: I didn't leave them unattached, there are just no coolant lines to where the filter housing is on my motor.

Cool thanks alot guys. Is there a spiecal hose or is it just bulk.

Re: oil cooler
 

Any automotive hose works, consider the 90 oil filter housing with external cooler, its easier to work with...

Re: oil cooler
 

I don't run one in my talon either.

Re: oil cooler
 

JET - Your oil is not cooled?

Re: oil cooler
 

Nope, I don't think it has been at all with the 2.4. I do plan on adding an external cooler pretty soon though.

I would run a oil temp gauge if you do not have an oil cooler. I did not run an oil cooler on my car, but it never ran for more then 20min at a time and the oil temp leveled off around ~220f, I did not do anything until my oil temp was at least ~180deg. If you do not run an oil cooler you need to change your oil more often, the extra heat breaks it down sooner, etc.

People running E85 shouldn't have to worry about it quite as much either, since it runs cooler. I am not saying I recommend running no oil cooler as I plan to put one on my car. It is always good insurance.

Re: oil cooler
 

A lot of kinds of cars don't run any kind of oil cooler and you can go overboard on the oil cooling. Having too cold of oil isn't a good thing. It depends on how the car is driven also and how much you change the oil. I have seen multiple motor ruined because the owners tried to increase their oil cooling, but none of them were DSM motors. I like to get rid of the horrid sandwich cooler on DSMs and goto a 1990 setup or a aftermarket core with the 1990 filter housing, just to get rid of the dangers of the 1 bolt that holds the sandwich cooler on backing off.

Yes, an external oil cooler in the winter can be very risky. The oil gets thicker in the cooler and can become a restriction. Is that when you saw the problem Shane, or was it in a warmer month?

Re: oil cooler
 

I guess I was lucky with my 90 oil cooler and 20w50 when it 10 below out then. Oil is picky, it does not want to be to hot, or to cold.

Re: oil cooler
 

I have heard of people who have an oil thermostat, has anyone tried that? i could imagine that it would benifit those of us with 300HP+ cars that drive in the winter....

Or would a piece of cardboard in front of the cooler do the trick?

Re: oil cooler
 

Cardboard would definitely help. I have seen a car with a bypass that they used during the winter. I am not sure how well that worked, it was in a build thread. A thermostat just like the coolant uses would be a great thing, but I have no idea how a t-stat would behave in oil. With an AEM you could probalby trigger a bypass valve by temperature, not sure if your DS thing will do that.

*yawn*

There are actually OIL THERMOSTATS that are, well, DESIGNED to be used in oil lines.

Something like this:

Re: oil cooler
 

So you guys are talking about the coolant lines that run to the oil filter housing right? Cause mine ended up coming loose and when the oil pressure gets high it'll push my oil into my coolant. So couldn't I just take the coolant lines off and be fine? (Other than the fact that my oil wouldn't get cooled as good obviously.) Sorry for thread jacking I have just been wondering about this for some time..

Re: oil cooler
 

No, we are talking about external oil coolers, like on the 90's. Your oil won't really cool at all if you loop the coolant lines.

Re: oil cooler
 

So would it be ok to just loop the coolant lines? I would just need to change the oil a little more often and watch my oil temp? I wouldn't be running it like that for long. Just til I got a new oil filter housing.

Re: oil cooler
 

I hate 'integrated' oil coolers that are buried in the radiator. Those things are a wrecked engine waiting to happen.

On top of the obvious problem of possible cross contamination between fluids, you are subjecting whichever fluid is cooler to the heat of the other fluid.

Say your engine coolant runs at 275 or so and you want your engine oil at 200. Now run all that through an 'integrated' cooler that shares fins and mounting space.

Aftermarket oil coolers (engine and tranny) as well as uprated hoses, thermostatic valves in the lines, etc, etc are relatively cheap. Work up the prices yourself and compare that to the rebuild costs of an engine and or tranny damaged by contaminated fluids.

Builders (usually) go all out with new engine seals and gaskets. Why not apply the same logic and discipline to the cooling systems?
