You've got a winner there with Jonathan. He's patient, strong and smart. He's learning skills from you beyond mechanics including how to be a great teacher, businessman and leader.

Scott, you and Jonathan are doing an excellent job with this rebuild. Love that you're mentoring Jonathan with the nuances of engine reassembly, etc. Also love your improvised remedies such as the lopped off head bolts that you use to ensure proper alignment of the cylinder heads as you're carefully lowering them into place. Too many careless mechanics botch up jobs like this by dislodging a head gasket, shims and/or o-rings. I'm convinced that this is a chief cause of coolant-in-oil seepage on prior rebuilds. Kudos to you for doing such a great job in tutoring and mentoring Jonathan. He's a patient young man.

Solid, by-the-book, quality work! One shop tool you may wish to consider is a bead blast cabinet. Such a time saver for castings, housings and perfect results. We have owned a Zero Blast for many years and are addicted to it!

Great video and I learned something, I never would have thought of lock washers allowing water to travel into bolts/fasteners. That is good to know. I love seeing anti seize and I wish more people and factories used it.

Have you thought of getting one of those laser parts cleaners? They are amazing and quick for burning paint, rust or whatever off of steel, aluminum or cast iron parts. If you haven’t seen one do a search on KZfaq. I’d love to have one but it’s to much for the amount of dIY stuff I fix, you guys on the other hand woukd really benefit from getting one and they aren’t that expensive. As usual great video, love you guys!

Good work on a big project. I am a bit concerned with the lack of "meat" on the outside of the bolt hole in the intake elbow when the hole was redrilled. I can see that cracking in short order.

I install studs where possible to eliminate seized bolts. Installing Time-sert thread repair inserts in aluminum housings also helps eliminate seized fasteners.

@BusGreaseMonkey 3 ай бұрын

It wouldn’t help there the thermostat housing seize on the shanks. The anti seize and flat washers will do the trick

@kenore4003 3 ай бұрын

Saw an interesting video from Gale Banks on using studs on a Diesel engine. He says do not use them because bolts have a tiny bit of give that let's them take the strain. When studs are used they do not have that give so the threads in the block do leading to them pulling out. So studs do have a place to use and places to not use them.

Scott, I was wondering why you don’t use the Quinn Digital Torque adapters that you got from HF, to tighten the fasteners with? Did they break or do you not trust them over the click type?

@BusGreaseMonkey 3 ай бұрын

The icon click is easier and better for the task but if you don’t have the expensive one the digital one will do great

Can you tell me about your injector cup set? Is that an old Kent Moore? The components looks similar to the Kent Moore kit I use but I don’t see the small reamer cutter bits? Would love to see you installing the injector tubes and adjusting the cam roller guides please.

@scottbenjamine4890 3 ай бұрын

scott, are the detroits as suceptible to cavitation as other diesels with wet liners? every time i see you open up one of these with either improper coolant, or no coolant at all, that the first thing i think of is how bad are the outside of the liners. great video!

Would you mind expanding on your issues with the oil feed line. I have a 6V92 and this line (DD #8923538) seems to be in stock at the usual places for around US$60 plus shipping. Is the 8V a different part number or was there something else involved. Thanks.

We had the ends we were just trying to order the aeroquip hose for it. The wrong diameter showed up 2x The supplier then checked their inventory and said they didn’t have the correct hose.

It does in this application (where a long shank bolt goes through a close fitting bolt hole). I have seen many times where the long unthreaded shank of the bolt became seized in the bolt bore because anti-seize compound (or grease) was not used.

OOohhhh...you mention that inner seal on the water pump keeps oil out?! Can that be changed with the pump on the engine? I have had a bit of oil getting in my coolant. Previously changed out the outer water pump seal as coolant was leaking out the weep hole, wonder if that inner seal is where I'm getting oil in the water?
