My first experience with a 6.7 Cummins was a previous failure from another local machine shop. I had just switched over to diamond and cbn hones. Made a call to Total Seal and took notes. It was unnerving seeing the change in the cylinder wall surface finish. It worked. Was able to follow up with a few more 6.7 engines and bought a profilometer. When you see top rings that are just .015- .020 thicker than the oil control rings it forces recognition for change. I’ve honed on blocks since 1991 at four different shops in three separate states. There were no differences between methods or grit choices between any of them. Things have changed.

Quite common to run across the "it's good enough we've always done it that way" ego blocking the learning of new things.

Just found this channel to listen along while at work. 22 and work in a machine shop for 2 years now, so I love these videos.

Haha nice head gasket😂 I did that once ,on a vw diesel. It blew right out of the #3 and made a heck of a noise like i had jake brakes. It was dark out of course,and when we pulled over and looked around it wasnt obvious. So i told my buddy to bump the key. Splash, i got like a quart of coolant blasted all over my lower half. Hey i found the problem 😂 Thats when i figured out that an injector pump that would be really strong for a 1.9 was just a little much for a 1.6. Fun while it lasted until replacing gaskets all the time got old.

Cool vid lake.im a inline 6 lover shows how far diesels have come petty impressive.lake could you talk about bearings tech and coating.peace

We need a video on the bottom line of 0W-8 oil on the new Toyota's. My 2024 Toyota Corolla LE I purchased last week (Mar 2024) has the "dreaded" 0W-8 sticker. This grade of engine oil is hard to find (even at Toyota dealerships) and expensive. Is 0W-16 OK to use long term? 🤔 Owners need to know.

What do valve reliefs in a cylinder head look like? I know the circle cuts on pistons are normal valve reliefs

Won't be long and 8 to 10k rpm ranges will be the bench mark.. extracting more power and busted bits in persuit of extreme lasting power. Ceramic top and skirt coated slugs.. 😂😂

Very interesting. What happens if u have a small amount of 2 stroke oil in the fuel. ??

@TotalSeal

3 ай бұрын

It could cause pre-ignition.

@nerd1000ify

3 ай бұрын

In spark ignition engines 2T oil acts as an octane rating depressant. Hence pre-ignition mentioned by Lake Speed. Diesels can't pre-ignite because they don't inject fuel until they want it to ignite. Adding 2T oil to diesel fuel is common practice for vintage engines whose injection pumps can't cope with the lower lubricity of modern ultra low sulfur fuel. But it doesn't do anything for the piston and rings. The same benefits can be had by adding some biodiesel as well.

How do you think this would translate to 2 strokes?

I actually I was wondering if you couldn’t just get by with a total seal second ring and running no oil rings. With boost try to blow everything back to the pan anyway maybe it would be a minimal enough amount getting into the chamber when not running hard to be ok?

Lots of them, watch more engine builder and race channels. Also you can get close with math. At the drag race strip, knowing the car weight, approximate aerodynamic drag, elapsed time and trap speed, you can use that information to calculate the approximate energy required to hit those numbers, and from that you can calculate the approximate horsepower the engine is delivering to the wheels.
