Re: oil cooler on turbo return? way to go or not
Yes, the turbo return line isn't pressurised and relies on gravity and a smooth transition to the sump. Introducing an oil cooler at this point will back up the oil to the turbo and cause major smoke issues as it gets past the turbo oil seal and into the compressor housing.Twistinchassie wrote:gday turboing a 3L toy, the turbo im running is only oil fed i was thinking of running a oil cooler inline from the turbo return to sump? can any one see any issues in doing so?

The enging oil has to primary functions, to lubricate and to transfer heat. The more heat remove from critical components such as crankshaft and bearings, turbos, camshafts etc the less stress on the engine and the longer the life span of the engine. Engine oil coolers are one of the most under rated mods. Anyone that uses there car in extreme conditions will gain advantage from an oil cooler.
If it is a quality product fitted sensibly it is not at all a liability, but more so an asset.
I'd suggest you find a way to fit it in the feed line or get an adaptor for the filter..

it already has an oil cooler on the block, and extra oil cooling is not usually necessary when adding a turbo to this engine. you can maximise the effectiveness of the built in oil cooler by ensuring the cooling system is in top condition.
if you are dead set keen on adding an oil cooler, get a sandwich adaptor to go beneath the oil filter. putting it in the turbo return line is a bad idea for all the reasons already mentioned and more. even if there weren't flow and restriction issues, the turbo oil feed just doesn't flow that much oil, so any cooling effect would be negligible.

no worries i thought it would of been benifitial to run one but i was un aware of there already being one on the block, ive upgraded the radiator and am about to switch to thermo's. if the std setup will be ok id rather not have another oil line to blow/ come loose on the trail. i dropped the altenator feed line ages ago on daniel rd in the wattagans. not a fun tow home.
