- In this video, I install a new cylinder head gasket, install the cylinder head and the cylinder head bolts to spec. We discuss the types of engine oil needed for a rebuilt 258 engine and for the AMC flat tappet cam. We also install a new valve cover gasket and the valve cover. We cover the type of sealant, gasket material, and all of the torque specs for the fasteners.
I was watching your video to learn how to change a valve cover gasket on my 1974 CJ-5 and realized you were wearing a Miami university T-shirt! Go Red Hawks! Class of 2007 right here!
Excellent. Class of 94 for me. Really miss Bagel and Deli as well as Skippers.
Great video. Thanks for having the patience to make these vids. I certainly don't. I have an '84 also and have been working on it as time permits. Ran like crap and turns out previous owner blew out #4 piston. Tore top end and oil pan off and learned previous owner had bored .060 over and turned the crank .010. So, it's taken forever to get new pistons. While I was waiting, had a machine shop do a valve job, port job, and mill the head. Finally got the pistons, had the shop put them on the old rods, and am just now getting to rings and bearings. Left the block in Jeep due to space constraints in the garage. This has been a huge pain, but I know it'll run great once it's said and done. Anyway, forgot which head bolts went where (stupid mistake not to make a note prior) and I noticed this video was done a couple weeks ago! Helped immensely. Also, will you continue to run the Rotella or was this only for break-in? I'm going to try it, but didn't know if I should switch back or continue running it. Thanks, boss!
Rotella for now on. I plan to have this CJ outlive me. :)
right on. told my wife she could bury me in mine, but i suppose having it outlive me will suffice. thanks again.
Had to tackle this today, helped me a ton. Thank you so much!
That’s a big tackle :) hope it goes well.
@@coolguy_CJ7 Yes it is! This helps alot though, your videos are a wealth of knowledge!
I added the Chevy rocker cover gussets to my steel 79 cover after re flattening the bolt holes. Helped a lot.
Interesting. How did you figure that out?
Had a buddy suggest it as a possibility.
What a nightmare! Can only imagine how frustrated you were. Good to see you're still working on it.
Good stuff! As Always.......Excellent detail. Thanks Man!😎😎
Thanks for sharing! Sorry you had some troubles!
Years ago, I had an '85 CJ-7. When I went on deployment with the Navy, I left my Jeep with my brother. After I returned, Doug picked me up in his car and drove me to his house. On the way, he said "Well, I might as well tell ya". I asked what, and he told me he burned up my CJ. Apparently the plastic valve cover warped (or something) and started leaking oil onto the hot exhaust. It lit off after Doug drove the Jeep and he saw the front end engulfed in fire. He put it out and spent the next 6 months rebuilding and repainting the Jeep while I was sailing around in the Persian Gulf.
Went right with an aluminum valve cover right after that fire!
What a horrible scenario that worked out with a great outcome :) I can’t even imagine what he felt when that happened.
Another great video! Keep 'em up! God Bless!
Great information thank you!!
Glad to help. It’s my only goal with these videos.
1981 is when they started using plastic valve covers! 🇺🇸🇺🇸🇺🇸🇺🇸
Jim Horan for the Win!! Thank you for the update. I didn't realize they started that early. I thought it was when AMC really started to see the end.
@@coolguy_CJ7 yeah 1981 is when they changed everything! I hope your engine fired up good this time! 🇺🇸🇺🇸🇺🇸🇺🇸
Ugh, such a sickening feeling when you know that you just accidentally hurt your baby. Great job repairing!
Dumb question. Replaced the head gasket on my 82 cj5. Although I kept the push rods and rockers together by cylinder, I didn’t pay attention to which rod went with which valve. It seems like the exhaust rod is the shorter of the pair. Does that sound right?
The push rods are all the same length and width. Are yours different?
I have a 1976 cj7 that I bought in 1994 and rebuilt the motor at that time. The Jeep set for many years and I just got it running last summer. I have put about 2,000 miles on the jeep and tried to do the proper break in but I started out running valvoline conventional 10w-30 and then changed it to penzoil conventional 10w-30. If I switch to diesel oil now will it still cure the metals? I also noticed in another comment that you said you would run diesel oil from now on, will you continue to run the zinc additive also?
Yes to the Zinc additive. It won’t hurt it, but will probably only do it every 2 oil changes. Your engine metals are already cured with that many miles, but the zinc will help. Switching to diesel oil only makes it better.
Hello Cool Guy, what are the two round parts included with the mahle gasket for?
Really good question. I, for one, did not use them and couldn’t figure out where they could potentially be used. I leave this answer open to anyone out there that knows.
Cool vid cool man...but my man!!??? What happened to your theme song?
It hasn’t left. I only use it on various vids. It is catchy though. :)
Sounds like my luck, learned the hard way,lol
Still not out of the woods yet. Engines running hot and there seems to be a radiator fluid loss.
I been working on a 1973 CJ5 Jeep 258 motor the front exhaust manifold stud leaking coolant I have tried different types of sealant and seems they have failed you any solutions are ideas.
So, you have coolant coming through the threads of the mount bolt? Are you able to remove the bolt? I ask because the bolt threads may be overly worn or maybe a little stripped. Have you tried to replace the bolt?
I have used high temp plumbers tape on bolts on my ‘84 258 and it has held up great.
@@coolguy_CJ7 I am going to replace the bolt and try some high temp thank you for the information
Please report back if it worked or not.
@@coolguy_CJ7 Sorry for the late reply I used the original bolt and use high heat tape Blue Monster- 70887 Thread Seal Tape so far it's holding up
What is your day job? You seem pretty mechanical for sure!
Would you believe I’m an artists? Art director for a creative agency.
Great video. I just want to ask what gasket brand you recommend for the aluminum cylinder cover.
@@albertomjoseph2560 Mahle or Felpro. Thick Cork exclusively. Along with the Indian head shellac.
@@coolguy_CJ7 Thanks, really appreciate your fast response.
@@coolguy_CJ7so, any leaks from the valve cover? I'm about to replace my valve cover gasket for the third time, because it leaks like a sieve at the back. I am about to go with Right Stuff and give up on the gasket all together...
Those valve covers. And the cork gaskets are garbage.
@@jtmartin8445 what are your suggestions otherwise then?
Dude, I feel ya. I've gotten pretty good at pulling the head, as well as the whole engine. I got an idea from my best friend about turning the front end into a "clamshell". Including a link to my build thread on the Jeep Forum; post #85 has pics of the clamshell. Basically, unbolt the front fenders, install piano hinge. Then, all you need to do is unbolt the fenders from the front grill, and they'll swing open, granting MUCH easier access to the engine bay. A couple of different ways to handle the marker lights/wiring. It also makes it easier to pull the front grill and pop the engine out. I use a HF hoist, but I have a JEGS engine stand.
Also, for future ref, you can use the hoist bolted to the rocker stands to put the head in. Saves on your back!! There are pics in the thread of using the hoist to put the head back in.
Another suggestion: put the money into ARP bolts. The stockers can stretch, leading to more issues. Yes, I know about it from personal experience.
Your videos helped me a lot on my journey.

PS - There are some videos of my build on my channel just to document progress; you have the "how-to" videos locked in!
That is crazy! I noticed that you cut out some of the inner fender wall. Was that to fit over the tire? Did you use a stainless steel piano hinge?
@@coolguy_CJ7 Yep, had to clearance the fender to fit over the tires. And yes, I used stainless piano hinge, and riveted it into place so it would close up.
