so i went to drive the truck to work on tues, and made it to corner store for a drink. went to leave and had zero oil pressue, the warning light beeping at me. so i shut it off and checked oil, it looked full and clean. so i started it up and still no oil pressure, so very easy and gentle i drove home and before i got home oil pressure came back, light went out the beeping stopped. oil pressure was 20 psi at idle and if i touch the throttle just a lil, it would go to 40psi then back to 20 as soon as i let off. i took the dd to work and when i got off i started it up and zerressure again. so i checked the oil fill cap on valve cover to see if oil was actually moving and maybe the sensor was going out. nope, no oil up in valve covers and it wasnt moving around on dip stick. so today i drained out the oil, and Damn it was nasty black and the plug had some metal stuck to the mag. then i cut open filter, and i found a few small pieces of metal, but all the oil was metalic and i could run a mag over some of the oil on the counter where i cut open filter, and it would pick up a **** load of small metal flakes. and i found a few pieces of metal at bottom of pan and a small pin looking piece too. so im having a bad day. im crossing my finger that the oil pump went out and that its not a spun bearing. i looked up at the crank and felt around trying to see if i could notice something wrong, or loose or and scratches. but nothing. so something somewhere is shitty out pieces of metal. i will have pump off by end of day and have it torn apart to see how the inside of that looks. ill also post pix and keep everyone informed.

 

God speed sir........

 

Good luck man...have you messed with the oil pump/pickup at all? A lot of guys run into problems with pinching the oil pump o-ring, or installing the blue/green o-ring which doesn't seal properly and causes oil pressure issues.

You mentioned a pin in the oil pan...could that possibly be a needle bearing from one of the rocker arms? Not that that would cause an oil pressure problem though.

I'll keep my fingers crossed for you that it's a cheap and easy fix.

 

So #7 lifter bit the dust. It's trashed. So I'm the process of remover all lifterz and cam. Depending on how the cam looks, ill be ordering a turbo cam regardless

 

I'd say unicorns. All up in your valve train.

 

Pix added to first post

 

Yep, fubar for sure. What cam/lifter combo was that? Original lifters, how many miles?

 

Lifters were stock. 90k miles on them. Cam was a fti, 218/224 .600/.605 111lsa not really a turbo cam but, I'm getting ls7 lifters and looking at several diff turbo cams

 

Did you figure out what the actual cause was? I'd hate to see you put it back together and tear up a new cam and set of lifters. I'd be curious to see if the lifter actually went bad or if it was just a casualty of being run with no oil pressure.

 

It's hard to say. My oil pump has a little bit of wear on the inside, it has that start of a small lip on the edge of it. But we were thinking my cam having been set up for a N/A motor, having the lifts right at .600/.605, that maybe I was floating the exhaust valve caused by the large amount of back pressure from the turbo. So we think that the cam was spinning around and smashing into the lifter instead of rolling into it. Idk if that's what happen for sure, just a thought we had while we tried to figure out the problem. The lifters had 90k miles on them as well. My next cam will be a turbo cam. I'm looking at the isky "triple 12" 212/212 112lsa
Then the brutespeed cam which is 232/240 .595/.608 115lsa
And last, a turbo cam from slowlsx, 228/222 .588/.581 115+2
So we shall see what happens now
