Default Well S***

So let's place bets on what is happening. Looks like motor is eating itself. Went to replace lower pan gasket to day only to uncover issues.

These last two pics have some crap in them that was already in the strainer on our oil drain cart.

So in the pan I found a pure pieces of black rubbery material. Not too large, then we found what looks like a part of a valve stem seal. But since I did not notice anything until I dumped the pan and looked at the pick up I am unsure if that rubber piece was in the pan.

Everything for the most part is super thin which makes me think bearing but nothing was discolored and no unusual noise.

Yup. I'd be quoting a new motor if that came through the shop. I just did one with much less in the pan but about 3x as much in the filter.

Had one of my good fleet customers have the same scenario. Doing a lower oil pan, found the same chit. Cant see anything with the design of the upper pan. He decided to keep an eye on it, and do oil analysis to keep an eye on if it was getting worse. He made it about 2 months/15k, before it finally chit. It was popping thru the intake, huge clouds coming out of the oil fill and intake, and knocking pretty bad. Didnt tear it down to see what happened, but ended up putting a drop in motor in.

I've got a few used engines if you end up wanting to explore options that way, shoot me a pm.

It's going to be a cam/lifter failure.

I thought we were done with this after 6.0/6.4 but it's still alive and well...

We just put a motor in our 12’ 550 that ate a lifter at 148k miles. 14,000 hours though.

That's impressive! Average 45 mph on 14,000 hours would be 630,000 miles. Wouldn't complain about that..

This is Morgans old single cab truck I bought from Cody back in September.

So the body has about 85K miles but the motor is built and I would suspect it don't have much for miles on it considering what it was built for. I would guess that it is the original lifters and cam, I cant find anything that says any different.

Funny part is not knowing an abundance about these engines my first thought was cam/lifters because I had a built gas motor truck that had a bad cam core that started flaking apart.

I was waiting on a piece to fix the waste gate and piping so I could start having fun again. Guess it will have to sit around for a while with the amount I have going on. When I get the 2 post lift re-positioned and hooked back up I guess i will go ahead and pull the cab.

My truck did this. the second cam bearing puked and there was piles of metal in the oil. 2011's also had an issue with valves cracking too.

So.... How many miles have you put on it since you bought it from Cody?

Sucks when stuff like this happens.

From the picture I have of the odometer when I registered it to now about 337 miles.

Even if it was happening when Cody had it he would have never known because nothing came out when draining the oil. It was all in the pan.

Just reminds me of old times and why I told my self I was not doing performance stuff to my daily drivers anymore. I fixed the AC, then on thanksgiving I blew the metal flex connector to the waste gate and now this. Good thing it's not my daily.

Hate to see that... The pan was off the truck MAYBE 3000 miles ago to put the drain for the atmo turbo in and I've done 2 oil changes since then and never saw anything metallic. I never chopped a filter, but never had a reason to.

Possibly shavings from drilling and tapping the upper pan? Obviously you would hope that stuff was properly cleaned up but I'm just thinking of scenarios that are less serious than bearing or lifter failure.

The heads were just off too, so no signs of anything at the time but I can't say if the lifters were looked at or not.

When I as laying under there that was the first instinct. I got a light and looked up where the drain penetration is and there was not even a burr. Then when I went to grab the pan out of the oil cart there was way too much to be from drilling. They are thin and flaky and have to be from a rotating surface. I also thought about the heads just being off. All this makes me believe/hope this new and something is salvageable. Good thing you did not decide to DD the thing.

Delo 10/30 XLE, Cody would have to answer the rest of your question, he did not put a bunch of miles on it. I would suspect it had the oil change more frequently because of working on it than it did from driving it.

Are the shavings aluminum or iron?

Could this be the result of the tapping some hear after oil changes?

It's definitely not an OCI issue... the engine has at most 15k miles on it in 3ish years and I changed the oil once when I pulled it out of the garage after the winter, middle of the summer, and again when it went into storage.

I drove it to work most of the time, 3 track passes, 2 dyno pulls on a small tune, most of the miles on it were to and from Morgan's shop getting more stuff done to it. I did nothing but spend money on the truck replacing many parts out of caution and the only reason I decided to sell it because at the time it was the first time the truck was in good enough running shape I felt comfortable doing so.

Finally had some time to start digging into this thing. There is a ton of sh*t in these trucks. Been taking it slow trying to make sure I remember everything.



I just got the heads off and lifters out before I called it quits for the weekend.
Cylinders look good, all the pistons look identical, flashlight on the lobes of the cam look good.

Yeah unfortunately it's only been 5k ish miles since the heads were off. At least nothing was missed there, not that that is any consolation at this point.

Little up date.
Bullet went to the doctor “Midwest”
Diagnosis is spun rod bearing.
I been drink g about it since Friday and I guess I will let them know Monday to go ahead with the stage 3 long block.

Meanwhile in my very little free time am gathering other parts. Gonna get the coil spring buckets changed to 4x4 units, received my pmf track bar for lowered trucks, gonna do some wiring and fabrication. I am trying to not get too carried away. Have to also fix the mount for the turbo and replace the waste gate flex connector.

I am picking up some take off 4x4 cool springs Monday. Going to try opposite of what most do when lowering these trucks. Put a heavier spring in and cut coils out like back in the day. Hoping the heavier spring helps with bottoming our and let’s me keep same ride height. Can’t go wrong for $40.
