i have a 99.5 v8 5.4 and today i lost oil pressure and the engine shut down on me. i have no oil in the coolant system, no smoke, and no leaks. my dip stick was dry. i put 3 quarts of oil in and it started right up. my buddy told me that happened with his truck and he had to get something replaced but he forgot the name of it. has anyone heard of this?
That oil went somewhere, It sure as s*** didn't magically disappear. There has to be a leak somewhere or horribly worn set of rings if you're down 3 quarts.
1.) Have you done a compression check on the cylinders?
2.) Was the truck acting funny prior to shutting off?
3.) You're sure you checked everywhere and didn't find a leak?
4.) You're really sure you don't see an excessive amount of smoke on start up?
I remember last week you were putting the motor back together, what job were you performing then?
yes i did a compression check. i park on a driveway so i know there are no leaks. and there was absolutely no smoke on start up. i was at a red light. it went green, i hit the gas pedal, it took off incredibly slowly, then the rpm flickered up and down, i got good engine power so a second, then it shut off and i drifted to a stop. a man stopped to help and he had no clue what could have happened. im goin gto call some mechanics and the parts store today and get to the bottom of it.
I'm confused...Could you explain how engine oil can end up in the torque converter?
You'll have to forgive me for thinking out loud under the influence of alcohol. I did have a buddy a few years back who ended up with engine oil in his trans somehow on an old fox body mustang.
I'm just at a loss as to how you could loose 3 quarts and have an engine shut off if you're not burning it or leaking it.

Your forgiven...I have had a public brain fart before. The only way for engine oil to end up in the trans is by pouring it in there. I think your figuring the rear main leaking, but the only "opening" in the torque converter is stuffed into the tranny. Alchohol is involved in lots of accidents...not all of them are in a moving vehicle.
3 qts. of oil is alot to lose and not have any idea where it went, specially if the block is clean and there isn't anything on the frame or bellhousing. Maybe it started out 3 qts. down and and he thought it was full. I only put enough oil in the pan to get the oil pump started when I build an engine, then I fill it up after it's in the vehicle.

If you did put 6 qts in it from the start,it doesn't take 3 qts to charge the lifters, fill the filter and where ever else it might decide to settle. You never saw any smoke from the exhaust? Does your truck have an external/aux. oil cooler and maybe took a couple of qts. to fill?
Is it running good now and not using any oil? If so I would chalk it up to one of lifes big mysteries and just watch the dipstick for a while.

nope i never saw smoke from the exhaust except when it had the blown head gasket 2 months ago. and no external/aux oil cooler. the oil cooler i have pumps coolant. i dont know if that is standard on superdutys. the truck has been in the shop getting prepped for paint since friday. i should get it back tuesday and ill ride around and continue to check the coolant and dipstick. but it seems to run perfectly. i sure hope its one of those mysteries and goes away
so i got my truck back on wednesday and didnt make it halfway home before my truck did it again. same thing. i put 5 quarts in this time but still no oil pressure. i had to tow it home. it seems to have no spark now but i figure that is because there is no oil pressure and the computer shut the engine down.
Now I am stumped. I know Chevy has the oil pressure switch to shut the engine down. Didn't know Ford finally did the same thing. The oil can't just disappear- has to go somewhere. the engine is clean? Pull the plugs and tell us what you find..I would think that if it was burning it, you would see smoke. Just for laughs do a compression test and a leak down test and post the results if you wouldn't mind.

Perhaps this goes with out saying but I assume that after you added the 5 quarts the oil level was in the 'ok' range on the dipstick?
