Replacing Oil Cooler after eng . failure
 

I dropped a valve in my race motor and put a hole in a piston. OUch. Should I replace the oil cooler in the process of the rebuild to be certain nothing is released from it after the rebuild?

I'm probably the least qualifies to answer here, but I'm gonna go with 'yes' actually 'hell yes'. You should have everything oil related flushed out and cleaned by professionals. My fear with the oil cooler is with radiator type coolers there are very small passages that could still maintains small metal debris, and of course maybe they'll only dislodge at the least convenient moment after you hav everything together and run in.

Either replace or send it to Pacific Oil Cooler www.oilcoolers.com for cleaning.

If you have enough cooler in the car replace the engine cooler with the spin on filter, if not replace the cooler, not worth the risk, with front coolers post failure and proper cleaning you can put a filter to catch debris but not on the engine unit it goes right to the bearings.

Thanks folks for your thoughts. Got a new cooler coming.

304065, Thanks for the tip on Pacific Oil Cooler.

It's not just the oil coolers you have to clean, you really should clean every part of the oil system to get any bits in the crevices of the oil line fittings and external thermostat.
