Oil cooler safety recall - DT466

[ewo1]

So after doing an inframe in my second bus, 2006 Amtran, I found a dang oil leak right at the oil cooler/ filter housing.

Looks like a easy job to do, removal and re-install. Thank goodness I found it before I left to Texas with the bus!

I also found a safety recall sheet that identifies dt466 engines manufactured in 2006-2007.

The recall sheet talks about a cracked housing. Makes me wonder if this is what caused it to get milkshake oil in the first place!

The safety recall sheets walks you thru the process for getting it done. Looks easy to do !

I've actually been thinking about making an adapter plate that bolts on instead of the cooler that would let you run oil lines to a fan powered auxiliary cooler. I was thinking it would reduce the risk of oil and coolant mixing during failure and also reduce some of the heat being put into the engine coolant.

Do you think that would be something worth while or pointless?

Sound interesting indeed… pointless, I’m not qualified to answer that question.

Then there’s the egr cooler too to think about.

the EGR coolers were bigger failures than the oil coolers.. but those didnt seem to fail as often on the Pre DPF (pre maxxforce) engines.. im guessing the DPF allowed moisture to get trapped in the exhaust passages of the EGR cooler..

EGR cooler failures are usually pretty easy to spot.. you will get condensation steam / smoke out the exhaust in conditions you shouldnt.. mild weather after the engine is warmed up..

oil cooler you almost always have oil in the water.. and some water in the oil...


the oil gets into the water when the engine is running... the water gets into the oil when the engine is hot and recently turned off..



building an oil-air cooler.. youd want to look at the diagrams of water and oil flow in the engine to see if altering it would cause any issues.. I didnt realize there was a TSB on oil coolers... they seem pretty solid on the DT's.. the O-rings wear out at some point and cause leaks.. but thats an easy fix.. if the engine is older.. rebuild it... a bit of a pain to get to but on a conventional dropping the downpipe makes life much easier..

Uhhhhhhhhhhhhhh, you might want to edit the first line of your comment, cadillackid.

surpriused it even let me post it in the first place
