Wondered if this would work OK.
Anyone done it ? Or is it a bad idea ?
Stan

 

sounds reasonable, ive seen a few sunny GTiR owners who have done this...

mesh it in well just in case of flying stones you dont want it to leak or split

 

Thanks.

Been mentioned before Stan, cant remember if the experts said there could be an issue over lifting the oil that high, or some other reason?

 

I am seriously interested in this as well, FMIC goes in at the end of the month, and with 50 degree C summer days around the corner, an oil cooler would be nice. There was another thread previously concerned about the issues of changing the oil, and building up the pressure to 'pre-fill' the cooler after the change. Otherwise there is potential starvation (I assume) and big expensive engine bang follows.
I don't know the cost of the oil cooler and feed adaptor etc, but would probably pay for a fair few oil changes!

 

Everytime you turn the car over from cold it will take a lot longer to generate decent oil flow as it will always have to fill up the extra hosing and the cooler rad. This will increase engine wear considerably, IMHO.

 

Stan: Do you actually have an oil temp problem? What temps are you seeing? Got to say that I am of the same opinion as Murray and mounting a cooler remotely adds another setof potential problems.
What about increasing the sump capacity?

 

So what is Murray's opinion? Has he posted it on here?

 

you could put a non return flap valve in..

I assumed that if the oil temp was below 160F on startup, the thermostat would shut off the oil cooler so you run as std. ie not much time to build up pressure ?????
Only at 160F does thermostat START to open - fully open at 180F.
I would have thought that once running ie >160F, the 90psi oil pressure would not have a problem pushing it up 30cm to the oil cooler !?
But I am willing to be corrected by those who have done it !

Harv - SPA shows only 80-84C on roads after a bit of welly, but worried as old gauge showed 200F (95C) after similar !

What about an external resevoir tank sat low down somewhere, with the same capacity of the cooler, filled by the engine pump, a hose to the cooler, and an electric pump filling the cooler with a return to the engine? That way there is no extra strain on internal pump and there is always a good flow to the cooler. Maybe an oil catch can could be used as the resevoir. Come with built in sight, so you can set the electric pump flow aswell.
Or you could just tap and fit two fittings into the sump and supply the electric pump from there. Dont forgewt to add more oil if you fit this.

 

Stan: I would rely on the SPA and on that basis you do not need a cooler. Where is the sender located?
Moray: Very sorry about the miss spelling.

 

Harvey - temp sender over no 3 pot.
Strange that there was such a difference between gauges (Autometer and Spa) with senders in same place.

Valve wise, you cant put a one way flap valve on both oilcooler hoses, so it would still drain from the unvalved line.

If a thermostat was used, then this could cause even more trouble, IMHO, as it would postpone the drop in oil flow (as the oil cooler and associated plumbing fills up) until the thermostat opens, at which point, you are likely to have the engine under load. Not good.

Harvey, No problem. Not offended, just suprised.

 

Cheers Moray - I had not realised that when the thermostat shut off the oil cooler, it still allowed oil to drain out !!!!!! oops/bang! I thought the flow and return from the cooler was "isolated". So does it still stays open on the "engine" (rather than filter) side.

But if the thermostat only STARTS to open at 160F oil would still flow directly to bearings whilst a trickle went to the cooler to fill it with oil - so no big drop in pressure while it fills ???

I suppose electic valves on flow and return (instead of the thermostat), both triggered by the oil temp gauge sensor would be the money-no-object route !

Oh well - interesting to air possibilities !

It seems my invitation for anyone who had done it to contribute failed - or, for some (good) reason, no one has done it !!!!

Thanks again everyone for inputs. Will wait to see oil temps on track warrant cooler !
Stan

 

Can I assume that it isn't possible to pass the oil through a cooler after it has done its thing in the engine and is on its way back to the sump? I've seen this done on another car but can't remember what it was.

 

Electric oil pump?? Runs for a a couple of mins before starting the engine to bring the system up to pressure and a good even distribution of oil?
