Installing Jeep Piston Rings: Engine Rebuild Part 16

[@williamclifton1172]

Hi Dale, Thank you so much for your efforts. I very much enjoy watching and learning how to rebuild a 4.0. It's been a life long interest to rebuild an engine, and with an old 93 YJ in my garage with lifters loudly clicking, I'm looking forward to the project. Your self-deprecating and repetitive humor, with the cat running around in the background cracks me up. Thanks! We all need some levity these days.

I have been rebuilding a 1982 scrambler and your videos have been so helpful! Thanks!

[@howtodoit1779]

Very helpful video series. I'm using the piston and crank videos to figure out the concepts and processes for my toyota 3.4 rebuild, along with knowing how tk help my dad with his jeep's 4.0

[@timtimzim9921]

These videos are very helpful! Keep up the good work!

[@JeepSolid]

Great! I'm glad they're helpful.

[@wardperozuk2782]

Great job on this assembly! I like when you say “it’s taking a while”. Lol, I have been at mine for a couple of years!!

[@JeepSolid]

Haha. I guess it's all in how we look at it.

[@kentbrown8357]

love your videos, going to be getting my first wrangler the end of this summer.

[@BroncoSolid]

Nice feeler gauges, where did you get them?

[@JeepSolid]

Haha! Have to get my own set soon...

[@2moomoo11]

What do you do when the gap is too big or too small?

[@davidgomez3737]

This ^

[@consaka1]

While the oil control rings typically do not see the heat the top two rings do it is still important to make sure they gap properly. Ring gap specs change based on the intention of the engine use. If you plan to run a turbo or supercharger or nitrous then you need bigger gaps. Lots of folks think that if your gap is too big it will use oil but that is not usually where oil use comes from. Oil use comes from ring land wear. The side of the ring wears and pumps oil around the back of the ring. One trick I use is to do one piston and then use the ring in the piston to act as a stop to set the depth and square of the rings I am testing gaps on. I was glad to see you sized rings to the proper cylinders because cylinder size can vary and it doesn't take much for the ring size to be off and rings under spec can destroy a cylinder pretty quick. Side note: I am usually doing 8 cylinder diesels.

[@JeepSolid]

Cool. Thank you for the feedback!

[@dissociativecat7495]

you helped me out with the brown dog motor mount, I went over railroad tracks and broke the mount on the passenger side and the bolts are still in the block, I called brown dog and they said their mount would bolt up and work without removing the three broken bolts $ 143 + shipping . I have a friend who said he can weld nuts on and remove the old bolts but its nice to know brown dogs got it covered

[@JeepSolid]

Yes! They are very helpful.

[@roncharbonneau797]

What do you do if the gap is not in Spec?

[@URDAD939]

You have earned a sub!

[@JeepSolid]

Awesome. Thanks!

[@moabwheeling]

Your doing a really nice job Dale , keep up the great work . Have a great weekend . Take care !!

[@JeepSolid]

Thanks for following along! It's been a fun project.

[@jacjumpin7471]

Why didnt you check end gap oil control rings

[@Synclazer223]

Does the spacer go in the middle on the first groove

[@isaiahwoodbury5205]

Do you not check the oil control right gap??

[@dissociativecat7495]

oil ring also has a end gap of .010-.025 right ?

[@milesowre2802]

What would you have done if any of the rings didn’t have good clearance?

[@84quadangle]

I'm starting my engine build and having trouble finding the Master Engine build kit. Where die you order yours from?

[@Mrizing]

Love the channel been a big fan since the early days keep up the great work! I had a quick question I know this is off topic but I need help, if anyone here or you can point me in the right direction it would help me a lot. Heres whats going on, I have a 1991 jeep cherokee 4.0. 217,000 k miles on it, it was burning oil so I had no choice but open it up and see what is going inside. Took off the head saw bad burnt values so I started with the head took them all out cleanded them up and did value job with compound and that rubber tool to re seat them everything looked perfect after that seat was perfect also value steams where changed few months before this so they looked OK. After the head I saw the block walls where smooth with no cross patterns left, so I took all the pistons out rings where not stuck or brunt they moved freely, next I re hoaned the walls to make the crisscross pattern I removed all the rings and cleaned all pistons up everything was super clean and rings where moving like they where new I also replaced the piston bearings cause they showed sign of wear. Before I put everything back I did a simple test put one piston in and poured oil on top of it to see if oil would drop through the rings left it for 2 days no oil went through I did the same test before I did the hoan and clean up of piston rings and oil fell through within hours. So I thought this was a good sign. after hoaning and ring clean up I believed rings where tight and no blow by was going to happen. Then I put everything back in. the car stared perfect and I thought everything was great then I did compression test each read same reading 125.125.125.125.124 126. So I drove it about 100 miles and oil was below safe line, OKi though maybe the rings need time to set in new block walls but no 1000 miles later I'm burning even more oil then before almost a whole quart every 70 miles that's really really bad. My mistake I feel is because I didn't replace the piston rings ? But they looked totally fine and where moving with ease. Please what do you think I did wrong here? I don't want to give up on this jeep but this is crzy how much oil it's going through I'm willing to take it apart again trying to fix it, currently it has good power no blue smoke but the oil I just disappearing. Sorry this is so long but I'm so lost and any help would be greatly appreciated.

[@philliptaylor5981]

Wow, detailed job! Did you ever find out what happened?

[@jwilson6086]

Great video Dale. Informative as always. If you're anything like me, I talk out what I'm doing the whole time. So camera or not you're still saying what you're doing. Bonus you get to post videos for us to enjoy. Keep it up.

[@JeepSolid]

Haha. Thanks for following along!

You all probably dont care but does any of you know a trick to get back into an Instagram account..? I stupidly forgot the account password. I appreciate any assistance you can offer me.

[@trippjustice5032]

@Emilio Blaine Thanks so much for your reply. I got to the site on google and Im in the hacking process atm. Looks like it's gonna take quite some time so I will get back to you later with my results.

[@trippjustice5032]

@Emilio Blaine it did the trick and I finally got access to my account again. Im so happy:D Thanks so much, you saved my ass !

[@gordongman3423]

Did you check the balance on the pistons and connecting rods.. Just wondering. Most excellent how to.

[@JeepSolid]

The machine shop checked them out for me.

[@joshdoinggood8117]

Love the vidieos

[@JeepSolid]

Hey! Thanks for warching.

[@MrSlickmonster6973]

What do you mean 30 over? Why 30 over? What are the benefits? Thanks, love your channel!!!

[@JeepSolid]

Hey, thanks! 0.030 overboard to even out the cylinders. They had a taper to them.

[@MrSlickmonster6973]

@@JeepSolid what is the highest you can go? Does this give the engine more power or is it the same? Thanks

[@wescollins23]

Just curious how things turned out on this engine? I realized I screwed up on my rings when I was halfway built before I saw your video. I then followed your directions but now I'm nervous if the top ring is supposed to face a certain direction!?!? Did you ever have oil consumption issues after your build?

[@RaymondElswick]

This engine is not a v six 3.7 , but the ring installation is the same process for the liberty jeep 3.7. My ? Is can ring installation happen without taking apart the engine, by removing the oil pan , Then removing the crankshaft roller rod bearings, bolts and pushing the rod to the side and lowering the piston, removing it from the Cylinder, then replacement of the rings and returning it to the same place, put it back. ??' S are there enough room for this process.

[@jsk326]

How was the cylindericity of the 6 bores? I am happy to see you not just replace the rings. lol BTW, One piston build was enough.

[@jorgereyes5141]

Just subscribed.. awesome videos... rebuilding mine. Awesome thanks for all the info

[@jalatecompa]

hi i did the same on mine and set the second ring with the bebbel part facing down as manual says but i still have 120 psi on compresion test, i rebuild the whole engine ne parts too, so it matters if i set the first ring upside down or up? why so low compression on my engine?

[@nadelius1]

Dale, you ever think to write a book, or publish your notes? Your step by step processes would be like Chiltons for more advanced projects.

[@JeepSolid]

That would be nice. I'm thinking about what I could do. I'm glad you find the videos helpful.

[@LeviHeizer]

Are your pistons the correct size? They look too small when you are checking the ring gap.

[@JeepSolid]

The machine bored the cylinders to fit the pistons.

[@sxstexan1956]

Damn, good work Mr. Solid. One thing I noticed is Mr. Bronco is always missing when you have all the hard stuff to do lol.

[@JeepSolid]

Haha! So true!

[@Synclazer223]

On the Piston

[@Flyby-1000]

I'd love to support your channel financially.... but I have an addiction, the same addiction as you, and it takes a lot of my money to keep it going...JEEP LIFE!!!...lol. We're doing the Jeepin' For Justice Event tomorrow , it's going to be an absolutely beautiful day... Mostly sunny and 83*... Love Florida Jeep life!!! Are you planning on doing any "off-road" mods after you finish the motor rebuild?

[@JeepSolid]

Hey, no problem. Don't feel obligated at all to join Patreon. I appreciate your support and activity on my channel. Your event coming up sounds amazing! Wishing I could be there. I'm planning some mods on this project jeep. I want to get it running first though. Lol

[@iphone777]

I was hoping to see how the pistons are attached to the rods. Looks straight forward but knowing my luck I’ll mess something up 😂

[@JeepSolid]

I had the machine shop press the rod pin in on the pistons. I didn’t have a press to do it and was cheap for the shop to do it.

[@iphone777]

@@JeepSolid oh yea that’s cool. I’m pretty sure I know what to do but I like to see someone do it and so far your rebuild videos have been great for double checking myself! No one seems to have a video of pressing the wrist pins in 😂. I pressed the old ones out so I’m confident I can do it. That’s tomorrow’s project!

[@ujayet]

Any time you doing something that requires a close up.. please get that camera closer.
