that dude is a beast of a mechanic

[@thedieselpage]

At 13:40 into the video - I don't like the long sanding block and 80-grit paper your mechanic used. GM recommends a 3"x4" flat steel block and 600-grit wet/dry sandpaper used (with a light oil) in a circular motion to prepare the cylinder block deck (and head decks if machining is not required). The mechanic in the video didn't take any precautions to prevent sanding grit/debris from falling into the lifter galley, cylinders and water jacket. GM recommends using shop towels in those areas to help prevent contaminating the engine.

[@mattbailey6933]

3 quick things...that sanding block isn't flat enough, you need an actual lapping plate and you can't just go in one direction. Then the debris just gets Into the cylinders, coolant passages, lifters? You got to put something into those openings. A memory foam floor mat works well in my opinion. Last is check for deck and head flatness with a feeler guage and straight edge. Just my 2 cents.

Luke did a great job! That LLY is going to last a long time, and be a very dependable truck. I can't wait to win it!!

I’ve always heard the mahle head gaskets are the best way to go.

[@demarcosmalls8966]

i had the same work done on my LML .. pulled heads .. completely machined them .. ARP studs .. mahle gaskets .. and threw in new injectors too .. diesels are expensive .. so find u a good diesel mechanic and treat them well/right .. i do .. imho though, my next diesel will be a cummins .. all diesels break .. but those straight 6s and simple design make them less expensive to maintain compared to dirtymaxes and powerstokes ..

[@tonywhipple]

Exactly no pulling cabs on cummins and only one cylinder head keeps things way simpler

[@LBZDIRTYYMAX]

There’s a company near me that is known around the states for being the best at duramax headgasket jobs. They guarantee them for the life of the truck

Love the build man

[@JWMontoya]

Thanks! :D

[@MHConstruction_MN]

When I looked into doing head gaskets myself I found those are the best gaskets to do the job too. Up here that job runs $6-8k. Kinda wondering what it cost you cause I have some of the issues you saw.

[@JWMontoya]

He charges roughly $6k to do this job. Hit him up at @southerbuiltautoworks with any questions.

[@unboundghosts2512]

How much did it cost at the machine shop for the head work?

[@justinguerra5820]

Dope video!

[@St4ked]

Soo my head gaskets are done too?

[@quentinl1003]

Whatss all the gaskets used in the video

[@thruitallauto2538]

Most time head gasket troubles are caused by over heating them, how long did it take him to do the job

[@JWMontoya]

Day 1 to pull the cab and heads out. Day 2 waiting on the machine shop Day 3 Finishing up

@@JWMontoya wow I used to do that kinda work, love to see y’all younger guys doing this stuff, I’m 60

[@JWMontoya]

Yeah I think so

[@Salgadovisuals]

Hey man where would someone get a manual for doing a head gasket job ? More so want torque specs

That is a very intimidating to me. I just bought my first diesel. A 2016 Duramax. I know nothing about diesel engines. Almost feel like I made a mistake but its mine for the next 5 years anyway.

[@JWMontoya]

Make sure to get an Airdog Lift pump and add fuel addtives and you're good

[@kyle-409]

@@JWMontoya appreciate the advice

[@tonywhipple]

Junk engines all duramax from 2001 and up. V8 DESIGN IS BAD START FROM GET GO. PARTS EXPENSIVE, WORK EXPENSIVE. CUMMINS WAY TO GO. INLINE 6 ONLY ONE CYLINDER HEAD, VERY SIMPLE DESIGN VERY EASY TO FIX, UNLIKE POS FORD AND GM

[@leepierce3256]

very interesting content in this video, and I am spending some more money to increase my chances!

[@hunterharness]

Did you learn what Luke’s background was? I’m curious what training he had in the trade to be so knowledgeable to do head gaskets once a week, He seemed young to be so knowledgeable

[@JWMontoya]

You're more than welcome to message him with any questions @southernbuiltautoworks

[@thruitallauto2538]

I worked with a young guy who had knowledge like that, he new more than an older guy there that had been in the work for 40 yrs

Made him explain how he got the cab separated and cut it all out lmao wtf

[@OptimisticIguana-fu8mw]

I just did this job without pulling the body off. 😂🔫

[@foxgdsmck]

My vin is coded for lly, it's one of the last of 06 production, but when I ordered a new charge tube from the cold side into the y bridge, it is for a lbz and not the lly, it also has the 6 speed and not the 5, which I've heard that is indicative of lbz, if any one knows for sure?

[@JWMontoya]

You have a detuned LBZ. 06-07 is LBZ

[@foxgdsmck]

@JW Montoya whew!! Does lbz have any known issues? Mine only has 126k on it. Just got it a few weeks ago!! Very excited to have it.
