Hey Rob even though it’s an older video I still catch myself coming back to all of these older vids. Yet again another great how to video. One request I have is the next time you tear into a spare 12v or work on a customers truck that isn’t having any machine head work could you make a video of replacing or installing/ and or proper “placement” of valve seals (non top hat style). I’ve looked everywhere on you tube and can’t seem to find a good video on it. Thanks again buddy
I see a lot of people use air in the injector hole this looks way easier I’m glad I seen this my question is, is there still a risk of a valve dropping and having to pull the head I know it sounds like a stupid question but I really don’t want to pull my head again lol Thanks!
So you don’t have to have air pressure in the cylinder through the injector hole? Aslong as its tdc valve wont fall through? Everything else I’ve seen says you have to no matter what.
Getting ready to replace valve seals. Should I upgrade valve springs while I'm in there? And what should I use. Relatively stock. Fuel pin, hx35, not turned up at all yet. 405k miles, auto trans
Old video I know, but when installing new valve seals, do you need to use a sleeve/protector so the groove on the valve stem for the keepers does not damage the rubber seal when sliding them on? Cummins has a tool for this very reason, but it is ungodly expensive for what it is. - I’ve heard of people use things such as straws and heat shrink.
@@CUTTERUPROB Appreciate the reply. This is for a 2016 24v w/ 127k miles on the clock. Getting ready to install studs, Injectors, Manton valve spring kit, push rods and bridges. Along with lift pump and CP3. 🍻
Enjoyed the video. If Im Doing the 60lb valve springs only because I'm going to do 3/4 k governor springs, can I just replace the head bolts with new or do I have to upgrade to head studs? Thanks.
Thanks for the video. Im trying to install 60lb valve springs, but it seems that the keepers aren't moving. Can i cause damage to the piston to keep compressing the compression tool? Would it help to run the engine up to temperature, then try again? Thanks.
doing springs right now and i (should) have the motor at tdc on cylinder 1 based on the cam gear timing pin, does that mean cylinder 6 is also tdc? also from there how do i verify tdc on the rest of the cylinders?
Love the videos Rob would you mind going about checking piston to valve clearances in a 12v due to ether machine work or aftermarket cams ?? Also what are your thoughts on aftermarket cams and where they would be beneficial ?? Thank you for the educational vids really appreciate it.
I noticed during my spring and seal install that some of the valve stems have an extra groove just above the keeper groove. Is there a reason for this??? The ones without the groove were exhaust and grooved ones were intake.
Hey Rob, I need your advice on valve stem seals. I put 60lbs springs on my 97 12v a few weeks ago and so I replaced my seals while I was there. I now noticed 2 weeks later that my truck is burning oil. I pull my rocker covers off and every seal is popped off 🤬. I felt every one of them pop on on install. Is it because I used inferior parts? What should I use to replace them again?
are those head bolts torque to yield ? can you reuse them ? responsibly I mean. ? Thats the only turn off for me to do the springs is fuking with them head bolts , gives me the eeeby geee byessss
Thanks Rob i going to add a exhaust brake in the future and i was told i need the 60 lb springs ..
Awesome videos on 12v’s. Great content and my go to now for this platform. Thanks for the quality content!
Glad I can help. Share with your friends!

can do

If the piston is a tdc there is no chance of the piston feeling in. With air there is the chance.

@@logandemay9755 no need for air as long as the piston is a tdc

i do a set of 60lbs springs in it if it was me

Depends if the valve has a shape edge.
If they new and been sharp edge taken off. But you can buy plastic cheap ones.

@@BoostedVQUR on the 24v you shouldn’t really need a sleeve they don’t be burred up much. But they don’t hurt if you want to get one

You can just use head bolts if you want

yes sir
Did you ever do a video of how to find TDC of the other 4 cylinders?
I haven’t no
Love the videos Rob would you mind going about checking piston to valve clearances in a 12v due to ether machine work or aftermarket cams ?? Also what are your thoughts on aftermarket cams and where they would be beneficial ?? Thank you for the educational vids really appreciate it.
I can do a video on that no problem. I will do it tomorrow with the new timing video. I will also do one cams
@@CUTTERUPROB awesome thank you
video for piston to valve clearance will be up tonight. I will do a cam video soon
Maybe I missed it And I know this video is old. But what keeps the valves from dropping?? I know gas trucks you pressurize the cylinder
You hav Roy put the piston at top tdc to hold them up
Is there a reason to valve lash or check clearance on the rockers
Just a maintenance thing as thing get worn it needs to be set. Or if doing any engine work ( I.e doing a head gasket)
And the valves don’t fall in??? What about when you replace the seals, do they fall in then?
No the piston at tdc it can’t
You have a preferred brand for the valve tool your using here?
Any of them are good the tork Tek is the one I am using in the video
I noticed during my spring and seal install that some of the valve stems have an extra groove just above the keeper groove. Is there a reason for this??? The ones without the groove were exhaust and grooved ones were intake.
Just a reference.
Can I use stock keepers and retainers with 60lb springs?
Yes you can
Ok thank you
How do you get top dead center
tdc 1 and 6 you can use the timing pin on the back of the timing case
Brother super work
thanks !

I would do the hat style seals. Send me a email and I will get you a part number
Good video but U didn't show how U get TDC for each piston. No one has actually on any videos
i guess right right i will do a video this week
@@CUTTERUPROB do lease do ! Looking to tackle this project and would love to know !!
I second this comment
Was there a follow up video I can't find it
Head bolt torque at 110 if you're brave 125, Is 115 brave or still a pxxxy ? joke aside why not somewhere half way ?
are those head bolts torque to yield ? can you reuse them ? responsibly I mean. ? Thats the only turn off for me to do the springs is fuking with them head bolts , gives me the eeeby geee byessss
You can reuse as long as there not out of spec
💯👍🏾
thanks for watching
