I know the lines leak, never seen a cooler leak.
x2 i have had a few with no problems at all.
They are a stacked plate cooler (best type of cooler). I haven't seen any leak but the lines I have. Even if the cooler did leak it's not the coolers fault if you "destroy a motor" it's your fault for not fixing the leak in the first place.
Sure its GM engine coolers you are hearing about?
Dodge has one for the transmission that is a real horror. They regularly rupture internally and fill the transmission with coolant without any symptom until the transmission stops working.

seprate cooler mounted in front of rad on the factory units for our 73-87 unless 6.2 oil burnner.
there is a gasket and oring that seal the adaptor to the block should be around 10 bucks at the parts store. have a good long handle scraper handy if the gasket is cooked to the block . and allen head bolts 2 of them hold it to the block. other wise easy fix more than likly.

Well, the factory cooler on my '90 ruptured on me outta the blue last month. Was creeping around in the high country, and thank goodness I happened to jump out to lock the hubs (didn't need to go into 4, just dumb luck). At first I thought my leaky steering box had really let loose, then I stuck my hand under the cascading fluid...
Figured it was a line or a fitting, but after cleaning everything up as best possible and running it for a second, had to be coming out of the cooler itself. Spare you the adventure saga, but ended up cutting the cooler lines below the unit and bypassing with air compressor line to get home.
I immediately ditched the whole setup with the standard oil filter adapter. Was good motivation as I had the aforementioned leaky o-ring on the top of the cooler adapter. Case closed.
After inspecting the cooler unit, no evidence of rock damage, etc. so have chalked it up to 260K+ on the cooler and that it finally just gave up.
Either way, that sh*t was not cool.

I had mine rupture on me 3 years ago, thankfully must have happened close to home because she spewed oil everywhere. I was broke at the time, so I just removed the entire setup and swapped in a standard filter adapter on the block. If I remember correctly, the factory rivet that attaches the oil cooler assembly had broken, allowing the cooler to vibrate slightly and caused it to fail... I had forgotten about it until now, definately worth checking if you have one, it's not like they are hard to get to! I haven't noticed any I'll effects to not having one, I'm sure it's a great plus to engine life, but it's nothing I'm in a hurry to replace.

Good point. My rivets had broken as well. I had re-bolted everything down months prior to the failure, but....
After mucho searching on CK5, I came away with a net impression that unless the vehicle is a relatively heavy tow vehicle, an aux. cooler may not be worth the failure liability. Being able to look over at a cooler that failed obviously punctuated my decision...

Just took mine off last night. Too much hassle, I do not enjoy taking my headers off just to change the oil.

Never thought of the header issue, but can totally see that.

Must have a weird fitting header, mine work fine and can change the oil filter without any troubles as well. 
As forr the oil cooler, I like mine, never any problems, I did change out the adapter gaskets/o-rings when the motor was replaced, but the hoses and cooler still work great. Just like components on the rest of the truck, it won't last forever and requies perodic inspection and repairs if needed.

Full hooker long tubes. I couldn't even fit a standard size filter in there I had to get a napa filter that was shorter. That barely cleared one of the pipes, and couldn't be taken off while the headers where on.
Wth, autozone and napa can't find this gasket and seal for the oil cooler adapter. Nearest chevy dealer is an hour away.
I don't have Internet at the house yet so I can't research for a damn, anybody got a part number?
