If you see a lot of sludge build up, You might consider adding something to your oil to clean up the oil passage ways. My ecm replacement didn`t work. So I ordered a new engine bay wire harness.
Good idea, thanks...

I'm going to start back on it on Tuesday when I get off these night shifts, I will keep y'all posted.

Update, Finally got some time to work on "ole Blue"... have it tore all the way down with front cover off, already replaced the secondary timing chains that I didn't replace the first time.

Now I am working on pulling the oil pan. I removed the cross member and stabilizer bar, I also removed the passenger side bolt and the lower bolt on the front axle to let it drop a little bit. I removed all the bolts from the oil pan. Is there any tricks getting this buggabear to come off... I am having a little trouble... found my trouble, missed a bolt on the bell housing (DUUHHH)... LOL.

Also had to pull upper bolt on front axle to get clearance to pull out oil pan.

Thanks,
MAC

SOOOO the oil pan was full of gritty sludge, kinda feels like chewed up plastic. The oil pick up screen was totally filled with the same sludgy material. Like I said, feels like ground up plastic. I have pictures but I am going to have to figure out how to upload from my phone...

Now going to reinspect all chain guides and everything plastic I can find... I don't know if it is plastic just feels that way. Only had a couple very very small pieces of metal that the magnet picked up... Calling it a night...

Seems like you’ve identified your problem but I gotta wonder what’s upstairs hiding in the solenoids? It would be horrible to do a repeat because the passages are plugged up. Did you get any pics.

If I was home, booze would be the reason 🤷‍♂️

The water pump was in great shape, no damage to impellar.

The VVT/VCT solenoids are new, only been through one test drive, maybe I can flush them out and the pickup tubes... what do you think?

You may be okay if you can get all that crud out of there. Be sure to pull the oil fittings going to the turbos. There are little screens in there. I'd probably just replace.

Once you get it running again, I'd let the oil settle and do another oil change.

I think it is coked burnt oil, not plastic, it is way too much to be plastic. Also looks to be all down in the oil pan and plugged on oil pickup screen. going to pull the windage tray and probably inspect a Main bearing tonight. Any thoughts on spraying a lube or oil up into the bottom of engine to ensure no coked burnt oil pieces are clinging to any surface???

Also going to try and download pictures still...

Thanks,
MAC

I thought full syn had a higher boiling temp than regular oil? Wouldnt that be the dino component in the mc oil?

I'd probably do a full cleanse with carb cleaner to get as many bits as i could then fresh oil, change, repeat.

I agree, also I will admit like I said in an earlier post I did go a few times with extended time between oil changes (instead of 5000 miles I went to 10000) I would not have thought this was the outcome, but you live and learn. That definately will not happen again!!!

Thanks

Hate to keep making work for you but I’d love to see what the inside of the oil filter looks like when cut open.
I will cut it open and look, no problem... I am curious too. This filter only has 3 test drives on it but we will see if it has trapped anything.

Thanks,
MAC
