Where is your oil temp measured, pre cooler or post cooler? I don't see 240 degree oil temp pre cooler causing this. I see it possibly being a symptom of the meltdown happening. What RPM were you at when this burned down, cruise or WOT? From the pictures the skirt clearance looks like it could have been tight, but if it was running lean and detonating you could have the same problem.

MT can you post a pic of the plate with the holes drilled in it on your pickups? I'd like to see it as I think I'll do the same. Thanks

It was about 5200. Afr at that rpm was probably 12's. I have to go by memory cause its tough to write legibly at those speeds. I honestly don't know if that's before or after the cooler. I'm using the threaded fittings on the remote oil filter/ thermostat housings. I'd have to trace the lines to determine before or after the coolers. Is there a standard it should have been set up for?

I made it work in my Donzi with an oversize ring and you could never tell. But then again I'm not a professional rigger I'm just a grease monkey and knuckle buster.

They were off pretty far. I've got pics somewhere. No way it was going together without cutting/ welding.

Thanks. Even after cleaning the strainers the intake had a baseball sized wad of seaweed up inside it. I have the exact same pic you do. If you blow it up you can see the intake. No screen at all and it was plugged.

On the remote filter is most likely before the cooler. (The way most stuff is rigged) You can get a bunch of discussions about where and why you should check oil temp before/after cooler. Mine was always before, and ran 230 all day long for 5 years, with no issues.

Crap, I missed your reply. Yes the filter housing is pre cooler, so 240 wouldn't have me worked up as to the cause of the failure. I am really curious what your skirt clearance is.
