oil cooler check?

[BruteNasty]

i was wondering if theres any way to check my oil cooler after pulling it off, to see if that was causing me to blow coolant. it seems to only blow coolant on my xtreme race tune, and not my tow tune.

sure was, it will be clogged with goo and casting particles... clearly visible. The reason is pukes with the hot tunes is because the cylinder pressure is significantly higher than the street tune...

x-2 what Pizza Pig said. There isn't any other way to confirm an F-d oil cooler besides monitoring the temperature delta of ect and eot as a way of external diagnostic but when you pull it out and dismantle it from the cooler housing, it will be apparent when you look down the o-ringed ports all the goo and crap present.

Mine was obvious cause there was still VC-9 and Restore present after I spent all day flushing, flushing.......................................... .................................................. ..and driving for 90 minute periods each time at full 194* temps. lol
