I was talking to my father in law he knows more about motors then I do he said just throw a new head on there and run it. Compression was all about the same in each and with a new head an head gasket it might help bring the numbers up?

 

IMO pull the head off and see what you're dealing with. Read sig. #3 may (should) come up with a new head and gasket if that's where the crack is. If there's a crack. Read sig.

 

Ill try that next. We put it up on the lift today and checked it out to see what else it might need to pass inspection it started right up no smoke no stage noises or anything and drive it right into the shop. It needed minor things like new pads and rotors, and one of the ubolts on the passenger side was missing a bolt and one of the exhaust hangers needed to be tacked back in place. Other than that it was rust free and looked good. So I think ill take it home to put new brakes and fix the bolt weld the exhaust back in place. Then pull the head and see if I can get someone to tell me what I'm looking at to see if its good or not. There has to be a video on youtube to help me everything is on youtube.

 

Start PB-ing all the exhaust and manifold nuts and anything that you're going to take off that looks rusty.

There's a bunch of good videos out there. I think the 2 guys who joke around were good. Forgot their names, one was an Asian guy.

I'm sure others will chime in.

Normally, the bolts should be un-torqued in sequence, but...

NM it's good practice anyway.

 

Roadhouse!!

 

As soon as you said the two guys and one was Asian I knew exactly who you were talking about lol. Ive watched several of their videos

Thank you

 

If your FIL aware of the milkshake in the crankcase?

You could absolutely put a new head on there. Although, some things to consider.
- With the new head, will the head have tighter tolerances than the bottom end? If so, you could be looking at blowby past the piston rings, this blowby could blow oil into your airfilter housing and dirty up the airfilter, throttle body, combustion chamber, foul sparkplugs faster, shorten the life of the Oxygen sensors, and shorten the life of the cataltic converters. This is a worst case scenario.
- Did water (coolant / antifreeze) get into the bearings? If so, this will shorten the life of the engine.

So, let's say you put a new cylinder head on it.
- How much is that in parts and labor?
- Now, let's say you find out the bottom end of the engine is junk. How much is it to pull the engine & transfer your "new" cylinder head to a new bottom end, and reinstall?

If your FIL is committed to helping you work on the Jeep, to include replacing the cylinder head & potentially pulling the engine, that might be a better option. Then you could learn a thing or two, save a little bit of money & have a bonding beer experience with your FIL.

Personally, I like the 3 year / 100,000 mile warranty provided by Jasper. Maybe there are better warranties out there? Is the warranty transferable to a new owner? This might be a good selling point. Maybe find out what this covers, if their engine fails in that time period. Car rental? Hotel, if out of town? Oil? Coolant? What will be on your dime, if the engine were to fail.

If you are going to drive it, Keep as much water / coolant / antifreeze out of the crankcase as you can.

 

I would say....pretend you are talking about a plane.....now you may think differently about how to repair it.

 

He was mostly kidding mostly lol..... he lives by the philosophy run it til it dont run no more then fix it enough to run it a little longer. Then when you cant fix it anymore replace it and start over. BUT hes also meticulous about proper maintenance so he can run it as long as possible. His YJ has over 400k miles on it. The body is rusting out under him but it still runs well.
The warranty part is the only reason im still struggling with the choice. 5 yrs unlimited mileage is standard and for 200 mmore its 7 years. thats why my mechanic said he put one inhis office managers jeep he said he could have rebuilt it but for the cost and the time it took to get the engine (3 days) the warranty couldn't be beat.

 

Interesting point. Thankfully Its not a plane its the 6 vehicle in my driveway lol. Its a spare to the spare to my daily lol.

 

then it sounds like a time to buy a good mechanics tool kit, a book or two and make time to watch youtube videos and expand your knowledge into the art of mechanical repair!!!
