[@aaroneustace7922]

He's 100% right about getting on it as soon as you can to seat the rings. I build motorcycle racing engines and I've argued with other builders who do three idling warm up cycles. I let mine idle for 20 seconds then gun it almost to redline. The cylinder pressure seats the rings and I end up with far higher compression and power. Nice to see someone agree with me.

[@YansenHaryanto4547]

I heard from my mechanic that hard break-in is not great for the engine especially for the cylinder wall and piston rings.. their explanation is "hard break-in like running it to redline will make the piston ring overheat and worn the rings too much and you will end up with lower engine compression.." what do you think? meanwhile, I just follow what the manufacture of my bike recommends..

I've watched these rebuild videos a number of times in the last year. Its informative enough I'm thinking about doing my 12valve rebuild with my little bit of experience. Thanks a lot!

Something is wrong here.. I didn't hear 18ft-lbs throughout the entire video!

It might be short, but it sure is skinny! Lol

[@Mayamax3]

I could definitely tell from the look on your face Rich that you were a bit nervous early on with that test drive. Perfectly understandable. That's a huge investment in parts & labor. Very cool to watch.

Fantastic job on the rebuild and an excellent “how-to” video on everything you did. Congrats to you on yet another successful project completion. Meteorologists are still trying to figure out where that low hanging blue cloud came from. 😉

I’m loving these longer videos

[@marscruz]

Cleaning up the hoses and the wiring makes it look so much better. Now that is what taking pride in your work looks like! It also reduces the chance that something will melt or break. Nice job. I think the owner will Cum' to love that engine even more than the original... but it may take a couple hundred thousand km.

[@bobbyvini3694]

[@chadfoust6942]

First class video and build once again Rich! The aimlessness of that slushbox just kills me though! When I put a toggle switch on my torque converter lockup so it hooked up in every gear it transformed my old 12 valve and I guarantee it would drop that zero to 60 by a bunch.

[@ChrisandSohee]

Impressive Video, Keep up the good work!

[@CLDiesel02]

I don’t remember seeing you cover this in the video. And I’m sure you’re aware. But fun tip, after installing the pump and before changing the timing, make sure the TDC pin under the cover on the pump has been removed and spun around. Almost every 12v I do, someone forgets this step and the flag shears off the end of the timing pin.

[@kevintucker3354]

The dog reference was great!

[@MicrophonicFool]

Love this shit. I get all my diesel information from you. Even though the overall operation of diesel engines is simpler, there are components you outline (often related to fuel injection and Turbo) which never occur to someone like me with a flat-head and 2 slant 6 Chrysler engines. One thing for me that SHOULD be universal... Gear to gear timing... I know it might be noisey, but it is positive

[@welshwizard822]

great job man, one of lifes few that takes care and does it right first time. There are not many I would trust my engine with , only three and you are one, im the other and my mates son who is a good conscientious worker who works like you.

Thanks much appreciate any advice.

Your customer grabbed a Transmission Heat Exchanger from a( his being a 1998 qaudcab ) 98.5-02 24 valve thats why there different. Did you reinstall the radiator first ? I did when I did mine,. I was pretty upset when I figured out I had to disassemble everything to install the Fmic first.

[@ApeShift]

I'm going to mail you my timing tools for the p-pump man lol. I never do them any more, they're getting old

[@jimkillen1065]

I really enjoyed the video . I don't see how the fresh engine with more timing would have equal to a engine that needs rebuilding . After the rings seat it should be good. One thing that might impress the owner is a 3 k governor kit . Really wakes up the motor in my option . I run a bit more timing in my old 95 and 215 injectors , 10 plate and 3 k governor kit. . Just me but the 3 k governor kit is a nice add on even if it a stock motor and a bit more timing . The timing is the one thing that I found that really add fuel economy

Hey Rich I just got a donor 1998 dodge 3500 12v/NV4500 with 210K. Im gonna Cummins my 468big block on my 73 Chevy c30 crew cab. I’m trying to get around 450-500Hp on it. What would be the best route to reach that without killing the budget?😂. Thanks brother for your time. Love your channel and just subscribed!!!

Can you do more content on that webasto? I've heard they will bring a truck up to 100*f in 15min and full operating temp in 1hr. In below freezing, burning less than 1 cup of diesel.. I believe they could be wired to a truck output on a keyless or remote start. I see nothing but pros for cold weather startups. They can be had cheap from Mercedes and other German diesels in a wrecking yard. Thoughts?

[@kevinmonseler3592]

Great videos. I live in central Canada and build natural gas powered Cummins. We use the 8.3 and 5.9 Cummins which are fueled by natural gas or propane. Have you ever seen or heard of this before? The 8.3 makes about 99hp and just over 300ft/lb at 1800rpm thru a 200 series mixer and Woodward governor. If you'd like to see pics send me email and I'd gladly send you some

[@kevinmonseler3592]

Oh and the 8.3 is either naturally aspirated or they come turbocharged as well which makes substantially more power
