Outstanding troubleshooting and information gathering. Nice work. Glad to see someone put knowledge into troubleshooting instead of preconceived ideas and folk lore.
A lot of it was finding some old timers that lived through this era. I don't think a lot of them get to the interweb, and their valuable knowledge gets missed. The guys on Detroit Diesel Enthusiasts really helped confirm my suspicions.
Good on you mate, you briefly touched on some of the 'urban' myths that are put out there by you tubers as if they are gospel, basically when 'operated' correctly maintained, and not abused these motors are reliable, durable and have inherent longevity 👍
This has been a known problem with the crosshead type pistons of Detroit Diesel engines ever since this type of pistons was used. From memory, that was already the late 1970s. In the Netherlands, tests were carried out with rubber seals by mechanic Piet Brokx (RIP) from Shipyard De Haas in Maassluis (SDMM department), who solved the problem. In my opinion, this should have been known to Detroit Diesel specialists for a long time..
I don’t know what kind of oil is in my truck. I bought all the 40w they had at the store and plan to buy some more so I can do an oil change. But if I gotta tear it down I’d rather not dump out new oil. So I need to find the issue.
Keep watching O'Reilly's Auto Parts if you need oil. They have it you can order right to your house and they usually run a 15% or 20% off coupon.. I am betting you have the same issue we had
I am a mechanic with 30 years of experience in these engines and even on the island where I live we have many marine engines and I continue to repair them, what the video says is true and another problem is that the spare parts no longer exist.

Great info, thanks you.
You got a subscriber! Thanks for the info. My buddy keeps saying blower seal. I’m gonna a pull inspection plates and have a look.
Thanks for posting that, I found it very interesting

@@RodC671 probably so. Is it a pricey one to fix?
@@poorfarm-nn6ii it will depend on what's wore out when you get in there. It's basically an in-frame rebuild
I just assumed that DD engines were supposed to have a mess of old oil grunge in the airbox since every one I have ever seen was like that.
I have seen x head pistons in as early as 1969.
I’ve got a 4-53 that will blow 2 gallons out the exhaust in 20 minutes
Let me know if you figure it out, or if this helps
