[Fot] Oil line & cooler flush

[Spitfire Racing]

Glen beat me to it! I agree entirely. Consider the cost of an engine vs the cost of an oil cooler and once you have those values in your mind; roll in the cost of a lost weekend – what do you want to risk? The problem with coolers is they often trap particles that can’t be simply flushed out with a low viscosity fluid. How many bits does it take to destroy a bearing? When you find out at elevated rpms it’s instantly a very expensive mistake.

 

To coin a cliché ; “ Choose wisely!” The cost of a cooler is cheap insurance. I always keep at least one spare on the shelf.

I have a specific test procedure that I use on oil coolers, prior to attempted cleaning.
It involves the use of a nasty-ass chipping-hammer, the pointy end...
Oil coolers are cheap, racing engines aren't.

I was in the industrial cleaning industry for a while and the only effective oil cooler cleaning I knew of was done by immersion in an ultrasonic tank with a pressured flow through the cooler. The ultrasonic action dislodged particulates which were extracted by the fluid flow through the cooler. This used aqueous cleaning solution (solvents do not work with ultrasonics) heated to 180*F and with a mild alkaline degreasing agent. It is cost justified in fleet maintenance settings, but buying a replacement oil cooler is probably less expensive for us racers.
