cummins 12 valve cam and tappet/lifter install 

You are a great mechanic and a pretty good fisherman. Very good video.

Really good in depth video hoping to see more

Hey man, you just happened to have 2 not so common projects the same as I am doing. I was doing some RU-vid search to familiarize myself with the two projects and you happened to have posted both. You are very informative and thorough. Good job man😃!! Lt1 411 swap and a 12 valve Cummins cam swap.

Great job. Now, I'm ready to do the same thing

Unbelievable. You’re one hellava mechanic.

The best video on this topic!

Like a magician 👏🏾👏🏾👏🏾

Muchas gracias por el video,Dios te bendiga guero.

I'm number 53 Thanks for the video. I am a first time 2nd gen 12v owner for almost a year I need all the info I can get. I thought my front main was bad though now I Have learned its just the tappet cover up behind the power steering pump where you cant see , all I can see is the oil oozing down the side. I didn't even know there was a tappet cover there. anyway thanks again. I am more confident in tearing into mine now . I couldn't help but to subscribe and comment, there are not many videos out there that are profanity free.

Badass video 🤙

Hahaha 🤣 that Cintas truck though!!!

Thanks Soo much boss!

i noticed that firebird auto tag and much respect to you sir. not easy to achieve a purple heart if that is what i am seeing. america-love it or leave it please. happy veterans day out there america

is that your purple heart plate? much respect! im a DV but not a purple heart. thanks for the video and your service. =)

Genius!

Job well done! It would have been nice to see the lifers being pulled into place but I understand you are working alone too😀. And placing cameras has to be a heck of a challenge.

Like your content brother, question for you, went to do the kdp on my 97 and found some bad bad things in there 😒. PO had it fall out and it cracked the timing case so he took it to a shop I assume and they replaced the broken gears and what not but all they did was leave the dowel pin out and JB weld the case, it leaks very small amounts of oil but I would really appreciate what you think should be done or if it will be ok in your opinion? Apparently I’ve been riding with it like this for close to 90k miles and never knew the real issue inside. Subbed cause you make your videos well and are good enough that I can feel comfortable to attempt the jobs myself brother so thanks!

Hey man Do you think you could do something like this with a lifter job on a hemi? I’m a dealership tech and have been trying to think of an idea to replace the lifters without pulling the cylinder heads and this got me thinking

Helluva job brother. Appreciate you sharing. Other than larger surface area with the 24V tappets, is there any advantage compared to replacing new with the 12V Tappets ?? Blessings from Canada 🇨🇦

Hey brother love the content! Can I replace my tapper cover without removing the injection pump?

Great video man @horsepowertube super helpful. I’m currently in the process of doing the timing case seal in my 2nd gen 12 valve, as far as making sure it’s all timed right I just make sure the plastic plug goes into place turning the crank clockwise, and then mark all the gears and I’m good to pull it? Thanks again

This is a great video, thanks for the hard work. I pulled my cam and buggered up the cam bearing. Does anyone know how to pull that bearing without pulling the head off?

did you already take care of KDP earlier? couldn't tell and you didn't mention it, also, did the dowels pull out of the tappets easily? Neat trick!..I am 2 hours East of Covington in hill country..I see you are in KY, but in the flat lands near a major airport...

I never seen something like that some guy on RU-vid didn't do the same thing you did working on a Cummins 12 valve

How long is your dowel your using? I bought 1/2” x 2” and I’m wondering if it’s too long.

When you install the cam gear on the cam shaft is there any kind of markings to line up for tdc

Please check engine timing mark settings and engine model check engine flaring mark settings thank you sir

Pero es un motor cummins 6bt..y tiene la tapa lateral...y puedes cambiar el levas..pero en el modelo cummins 8.3 no se puede...alli es donde estoy preocupado..

I was replace the timing cover seal and I was turning the balancer pully to get it off and I didn’t know about the pin. Do I need to go in and replace it now?

What is the benefit to replacing the tappets to 24v ones?

so my camshaft only comes out like 2" then it seems to be getting held up somewhere? the lifters seem to lift up the same distance but a couple of them are not lifting as high as the rest. Any suggestions

How much different is the 12v from 24v besides the injection pump

Only vid on how to do this, but I would say WHY you started drilling the holes instead of threading through the eyelets . . . because the string binds up in the guides and you can't pull it up unless you use tweezers or needle-nose pliers. But whatever, it's already said and done. I had to use a 3/4" x 3/4" 4' piece of aluminum edge to get the tappets out, but putting in was easy; I HIGHLY advise a second person who can hold the strings and pull them up and down as you do this; I also used a hi-powered flashlight but of course it was a cloudy day. Round the rough edges of the aluminum if you do this, so you don't damage anything inside, though it is a soft metal but will also help you slide smoother. and not get caught up on anything. Same way coming out and going in; top facing you. If they are smooth dowels like I had just cut a sliver in the top about 3/8 deep and make a tiny bevel to get it started; I used fishing strong fishing line and only left 1/4" excess past the knot. I was able to reuse my dowels but they were TIGHT, so be your own judge, had to wiggle them out with pliers. As for the height of dowels, no taller than 1-1"4 . . . the 24v are about a 1/4 shorter so going back in is faaaaar easier, with the half-pipe. -THANKS A TON!

Why do you have replace cam and tapets??

Good video. way to cheat the system!

Isnt better remove cilinder head to chk valves?? Also?

I wsh you would have retorqued the inner timing cover.

You really should have installed a new gasket behind the gear case. It will be leaking soon

How did you know that your cam was bad what symptoms were you having and are the tapets are bad I have an issue right now I started to have an issue with a my injection pump to wear the number one delivery valve was working intermittently ordered a rebuild kit for the pee pump but there's a lot more to it than just seals and aluminum little cups that you tap into the thing there's a lot you have to know about it show Ray shortly after that the thing started to develop a check and low oil pressure to where it sounds like it's coming from the middle of the engine I'm going to be doing piston rings I already got a new head new head gasket and I'm going to do rod main bearings also while I'm in there with wrist pin bearings for the rods haven't replaced the oil cooler yet but I'm planning on doing that too but I was thinking about going with a heavy duty push rod brand new tablets in a brand new cam just to be on the safe side I had a valve spring that broke it dropped the valve but it didn't destroy the piston and ever since that happened shortly after it's developed low oil pressure and a tick I wouldn't think that that happening would cause low oil pressure unless that was meaning to go anywayit had high miles on the truck over 400,000 me now but I originally had about three something on it when I bought it close to 5 years ago when I pulled the head off the day prior it says standard on the Piston so somebody's either put pistons and rings in it I don't know what else they've done but just to be on the safe side I figured I might as well throw a cam in it too Samsung fixing everything else let me know what your thoughts are and also the cam bearing should I replace them and could I be getting that rattler tick from them Cam bearing if one of them is bad thanks a lot

That's not the proper way to keep lifter from dropping down.
