Part 2: Full DURAMAX engine rebuild, very detailed

[@semmble2k7]

Great video! I had no idea they ran the cam shaft in opposite rotation to the crank on these! Partially explains why the firing order is so different from their gas engines and the old 6.2/6.5 diesels

[@TTGTO288]

Yes, any 2 gear timing set up like this runs the cam in the opposite direction as the crank. 300 Ford 6 cylinders, GM 2.5 4 cylinders ... etc ... cam does dictate firing order, but it is more so the crank and the companion cylinders then it is the cam. You can change a Duramax firing order with a different cam to try to extend crankshaft life. When cylinders 1, 2 & 3 fire one right after the other (stock) it stresses the front of the crankshaft, hence why most break in that spot.

That allen key on the oil pump is for torquing your pump shaft. The balancer and flex plate are best done with a locking tool.

Wow just in the beginning of the video you showed me things I didn't even know about thanks for this informative video I'm planning on building my motor to handle 1000hp

[@evilogrelorde9105]

Where is Video 3? Ya done yet? Great info.

[@albertorodeos497]

great information I'm starting to do the same project finding so much information I thought the rod bolts recommend Streck procedure instead of torque also checking your bearing oil clearance it's a must

[@wesco123]

Great job man! One nice piece of work rite there 🏁👌

[@TTGTO288]

All in all, a good video, but never lube the back of your bearings ... they fit tight enough that they shouldn't fall out unless you are pounding on the pistons to get them in and if you are doing that, i'd worry more about a cracked ring. You also do not check any bearing clearances or crankshaft end-play. Just because it spins with a prybar, doesn't mean its going to be ok when running.

[@wildjokerls1]

I was thinking the same thing when he said assembly lube behind the bearings. Absolutely never do that. I stopped watching a soon as I seen that. I'm a certified technician and was only watching to familiarize myself with a D-max before I start putting mine together. But can't watch someone teaching with bad advice. It angers me. Look at the procedure and read the spec sheets. Ughhh i can just see 1000's of guys slapping on lube then installing bearings.

Any update? Really enjoying the build keep us posted!!

[@modshop1828]

Very well done. Thank you

[@smokiethebear3334]

My cam gear and crank gear aren’t lined up, the crank gear is 180 degrees off. So single dot up, two dots directly center top.

How much this whole rebuild cost you?

[@danielbeam5814]

My compression is at 245 - 310 on the highest side ..getting a incomplete burn diesel fuel cold starts are pretty smokey

[@gm_central3389]

Could be a couple factors

[@danielbeam5814]

What kinda money we looking at to deck heads resize rods and block prep cylinder hone

[@gm_central3389]

Depends on the shop

[@woodyaguilar2112]

hey bro keep coming up with the good content 👌 one question about how much to rebuild the engine i have a 03 duramax and looking to rebuild the engine I appreciate it if you let me know about how much im spending salutes from California

[@anthonyjohnson2570]

Awesome Bro

[@dennisreelie1720]

Did you check the piston ring end gap? Is that an important step to take? If so do you use a piston ring grinder tool?

[@gm_central3389]

I did, I’ve done it quite a few times in these and I’ve never had any out of spec, usually good quality parts are spec’d pretty good

[@bradjohnson6783]

How much did the machine shop bore out ? And what size rings are you using ? Thanks.

[@gm_central3389]

They didn’t have bore it out at all, cylinder walls were fine. They honed it and I used stock spec rings

[@bradjohnson6783]

Hey bro, did you have to measure rod side clearance between the rods ? Thanks.

[@gm_central3389]

Yes, I did that off camera and the machine shop did that as well for me

[@bradjohnson6783]

@@gm_central3389appreciate that bro, I’m gonna be doing my lb7 soon. Did you get standard sized bearings and rings ?

[@Jt_6.0]

@@gm_central3389im currently trying to assemble a dmax but im having a clearance issue with trying to get the rod to slide into its spot because it seems to be hitting the rod from the opposite bank

[@danielbeam5814]

Lbz rods will hold 650hp no problem?? Sustained

[@gm_central3389]

Yes

[@mini_max8725]

Why use aftermarket rod bolts on stock rods? You know that the rod itself fails before the stock bolts do? Aftermarket hardware on stock rods is pointless

[@gm_central3389]

Because they aren’t much more and if I ever had to refresh or anything like that I can reuse them

[@mini_max8725]

@@gm_central3389 my point is stock rods are pointless. Stock rods will bend before the bolts fail, and if you’re going into it a second time that proves my point. If you did aftermarket rods you wouldn’t need to go into a second time. That is just silly.
