Oil cooler flushing questions 3rd gen
I got my engine rebuilt and my builder said i spun a bearing and the rotor rubbed on the housings. He said i should flush my oil cooler professionally, with a place that uses some kind of chemical flush rather then steam or water flushing. My questions are... Where can i find a place that does this? I called some radiator shops and they use the steam cleaning method. is it really even nessesary to flush it out? It seems like any metal flakes would end up in the oil filter. when i drained my filter i didnt see anything other then oil come out..

Everyone is going to tell you to do it right by sending it to a shop who knows what they are doing. Otherwise, pick up the Yellow Pages and start dialing some local shops (probably diesel shops) to see what they can do for you.
Having it done wrong can damage the thermostat which could possible stick closed (and that wouldn't be good).

The shaving will drop into the oil pan. There is a stainer on the oil pickup, but it won't stop anything smaller than a tree branch. Then the oil goes to the cooler. Those heavy particles can drop and sit in the oil cooler. You "hope" the filter would stop them from going any further, but you still should have the oil cooler cleaned out.
The real question is do you really want to take a chance on screwing up a new engine? That's up to you as an owner.

ahh yeah that makes sense. i guess somehow i figured the oil went to the filter then the cooler, but it's the reverse. Geeze it feels like as soon as i make good progress i have to wait for another part to get back, better then having to spend another 3700 on an engine though.

I would send it to a machine shop and tell him to acid dip it.most good machine shops clean engine blocks and cylinderheads cranks ect. i got stuff back n they look like new.
