Do you have braided stainless oil lines? If so I'd recommend checking all the oil lines. I've seen those things internally collapse closed, and the outside of the hose looked perfect.

The only braided line is the shot hose from the tank to the hardline going to the engine.

OK, 'nother thought....is there a pinhole leak in your cooler such that when the thermostat kicked the oil pressure dropped out for a bit?

No leaks anywhere that i could find, the oil is still all in there, the dipstick shows just about middle between the high and low marks.

Since we're guessing:

A piece of paper towel got into the tank and wound up across the pickup. It finally dislodged and things are back to normal for now. The loss of pressure caused the hydraulic lifters to hammer the valve tips, caused the piston skirts to scuff the cylinder walls, and put a lot of wear on your bearings.

Of course, if you drained the oil and checked the filter, you could get some idea of what is actually going on, but until then we can keep speculating and telling you it's all doom and gloom....

When did you change the oil last Sir-Andy? Sorry that happened...whatever the cause. I have an engine shipping Monday from an oil related failure = feel your pain!

Right before McMark moved his shop. The car hasn't been driven much since though.

Yeah, it only won the WCR AX. Maybe the flogging followed by non use has stacked up a toll?

I worry about this with mine. It's been sitting lately. They need to be driven regularly and filtered as much.

Question: Can sludge be flushed with chemical additives and such? I know there are a ton of products on the shelves that make claims. But, they must sacrifice good oiling in the process if they are dissolving that crap. Sigh. I hope this doesn't mean a tear down.

There should be like a dialysis machine that you could hook up to and flush every oil passage clean while offline. Heh.

Fwiw, in my search for information on hydraulic lifters for type 1 (not here) I came across guys that were having troubles with hydraulic lifters that ran a thinner weight oil for a while to help "clean things out". Maybe there is something to that? Do an oil/filter analysis first of course.

I had a friend years ago who would drain the oil and then fill the sump/oil pan with kerosene, run the engine for a very short time, drain the kerosene, then refill with oil again. He swore it would clean things out. Did I mention this guy was very "old school"? (IMG:style_emoticons/default/laugh.gif)

You can also send a sample to these guys. I know, this is airplane stuff but it's still an air cooled boxer style horizontally opposed engine. I have airplane oil checked every oil change every 25 hours. I know that sounds like over-kill but if my engine has trouble, I can't pull over and stop on the side of the road.

Second that. I lost pressure at idle once. Half way to the RRC one year. Caught a flight home. Went back with a trailer for the car. Had the filter oil tested. The viscosity enhancers were cooked out of the oil. No metal. My 20/50 was the viscosity of 20 W. Changed the oil every thing was fine. Ask the truckers in your are where they get this done.

really, just run the motor on kerosene? i guess if you want to see the main bearings in the sump. you want to flush, run a pint of atf in the oil and then change. there is so much detergent in atf it will flush it or you can use seafoam in the oil. or just run the motor dry, the heat and friction will flush it for sure.

Andy, thought I'd resurrect this thread in that your headed to WCR18. Did you discover the cause and correct it or was it a lifter or oil viscosity? (IMG:style_emoticons/default/confused24.gif)

Apparently this picture is from 2011.... (IMG:style_emoticons/default/blink.gif)

Way longer ago than I thought. But I don't remember changing the oil after this. But I am 40 now...

helluva lot of voodoo witchcraft ideas above

how about you just see if an electrical connection failed momentarilY since you got psi back again w.o.; any recommended voodoo soluitions applied?

even better - OLD SCHOOL - go get a $20 FLAPS analog gage & attach it temporarily - get instant answer!

FWIW the "old school engine flush" is 1 part kerosene or diesel to 3 parts new oil, run until it gets warm to the touch and drain. Refill with new oil, change oil in 500 miles or 8 hours. This is what a Navy mechanic told me anyway.

Come on whats the deal just no info since the issue,fess up (IMG:style_emoticons/default/biggrin.gif) ,don't think its bad oil with viscosity issues unless an injector puked and spat leaking raw fuel into the motor,this isn't a common problem but I don't know these motors much.
Did you have hyd tappet noise previous to shutdown ???.
Tried all those old mothers remedys but atf ,kerosene ,diesel ....good luck on that might have been ok on some old 1960 engine but not in this case.
Hope you get it sorted without $$$$$,good luck Andy.
