Blown Motor??? I think

As of late ive been on about 12 psi fluctuating up to no more then 14psi... Since i've turned up boost on my stock 3.0 my oil consumption and oil leaks have become outrageous...

Last night while trying to boost the car several times, each time a tremendous amount of smoke came out of my exhaust and the car would boost but when it hit, 45000rpms it would just jump to red-line in whatever gear i boosted in.. At the time i didn't think it but i imagine that my clutch was slipping and that caused this awkward situation..

The very last time of the night i went to boost the car i loaded it at 45000 rpms and boosted and it went but immediately smoked even more than any other time and the car began to overheat and it cut off at over 100mph.. i pulled over popped my hood oil was everywhere.. After letting it cool down i poured in oil and tried to crank and the starter was fried? I attempted to push start and when it did it the car sounded horrible and didnt rev past three grand.. then cut off

Today i changed the starter did an oil change and now it has a hard start but dosent crank or spark? Im guessing the motor is doneee.. anyway agree? I checked all my codes and have the same codes i've always had..

This car is my daily so im looking to get back on the road by this coming weekend monday the latest... I wish a miracle 3.5 with 3.0 timing would pop up if not im puttin back in a 3.0 probably a dek and put my mevi on it

sounds like you need a built motor 3.0 or 3.5 lol but have someone look at the camshaft in the oil cap to see if it is moving when you start it.

cams are spinning.. meaning the starter is turning the flywheel, but still no start.. maybe im not getting spark? would my spark plugs go bad all at once? would my coil packs go bad all at once?

Check your sparkplugs. You might have blown the seals and oil is puddling up/contaminating the spark plugs.

pulled the plugs wizard... they were gray on the tip and smelled more like fuel than oil... changed them still no start... I see no oil leaks... no cracks in the motor... the cams are spinning as i crank...

Im stumped... What i believed happened was the car was leaking oil so bad while i was attempting to boost it the oil pressure got so high it spit out my dipstick and thats how the oil got all over the motor...

So I boosted the car with no oil in it... it overheated then cut off..

If you ever start making feedpipes for the 5.5 gen let me know. I have a modified PFI setup on my 5.5 gen and would like to switch to a more effecient design. Also, if you have any questions about getting things up and running let me know. You planning on changing to a return style fuel setup on the 5.5 gen?

Where did the oil on the engine bay come from? Also overheated? Sounds like it blew a head gasket pretty bad, or broken rings causing crazy blowby(hence oil everywhere), or combination of both.

If your engine was pissing out oil, you may have gotten some on your clutch which would explain the slipping

How was your PCV routed?
