Truck Repairs: L10/M11 Cummins STC valve and injector adjustment

We run the overhead on an L10 Cummins with PT(D) top stop injectors.

I read the end of the book and now I'm reading the beginning. Wes, I've come back in time to tell you the injector set is the way to go! Oh and the intake gasket, make sure it actually fits. I've gota go, the time police are right behind me. Thank you for sharing!

This is turning into the "ADJUST" channel, clutch, timing, valves and next brakes, wheel bearing, etc, etc, ad infinitum. Here goes all your free weekends Wes. Take us along for the ride.

Great STC & Valve set procedure info and video but, Wes take it from an actual Cummins tech. Though they may look damn near identical, the L10 & M11 are two different same design engines. If memory serves the L10 is a 10.2L engine and the M11 is a 10.8L engine, this means injectors, cam, rods, pistons, liners and head aren’t all identical parts. AWESOME, engine though and good to see another young guy around my age wrenching on these old L10/M11, 855/N14 and K19 series STC Oh just a hint, check the STC Valve and injectors, the STC Check Valve & the injector Check Valves are known to get stuck or stick periodically!

Interesting. Thanks for sharing. I have no doubt you'll have it purring before long. That old girl has the right owner now.

Instead of going straight to running a rack, if I want find an injector quick, if the engine is cold. Thermo gun the exhaust manifold at each port from the head. You'll see the difference in the temp. Less than 30 seconds of running you'll know if you got one. Typically 5-6 in my experience. Of course they must be in the hardest spot of reach.

Good thorough video on the valve seting procedures on these Cummings @Watch Wes Work

Greetings from Brazil video helped me thank you very much !! but here I didn’t use a torque wrench, just a sales key and a small leaning was good!

I did a video not to long ago for the ecm style m11 and left some screenshots of the shop manual that also gives step by step for running the rack and Jake brakes.

I'm changing an exhaust manifold on a 1992 5.9 Cummins today. 5 bolts broke and I have 3 out now. Just two more. Not my favorite job. Take care. Looks like you'll have it running perfect soon.

Thank you brother for your vedio 🍻🍻🍻

[akfarmboy]

Thank you for video, I'm curious if you took IR temp reading on exhaust manifold of each cylinder?

Intake 14 Inc exhaust 27 inc injector 120 degrees

Too bad it needs more work but that just means more videos. :-)
