Just seen the better video you posted. Cyl 1 def looks like an oil/coolant mix. I say that due to the amount of rust in the cylinder.

Cyl 3 looks like it has some minor wall damage, possibly rings

Re: Rebuild or replace 3.7l

Thanks Jeff for the reply, sorry was typing that stuff out when you sent it, but yes I concur with your findings as well...

---------- Post added at 12:33 AM ---------- Previous post was at 12:30 AM ----------

What the crap happened to my post...ugh

---------- Post added at 12:50 AM ---------- Previous post was at 12:33 AM ----------

So apparently my original post somehow disappeared...So Here we go again..

So this weekend hasn't gone to plan, monsoon rains, my wife's birthday etc...so what little I did today here ya go..

I did put the plugs back in it and start it up, major vibration but no, shit my pants sounds like before. But as soon as I put it in drive and I could feel the transmission engage and put a load on the engine the sound started again, and I turned it off....so I decided to push it out and around so when I pull the engine I'm not dragging the engine crane in the grass towards the garage. After that I decided to pull the plugs...



Something to note with plug from cylinder #2, it was covered in oilish sludge and smelled like fuel..

So then I decided to scope all cylinders...

Cylinder #1
https://youtu.be/yqIl6wvxYac
Cylinder #2
https://youtu.be/OCla-ufi9ic
Cylinder #3
https://youtu.be/vuM3npZcGtI
Cylinder #4
https://youtu.be/0GqjMMziCj4
Cylinder #5
https://youtu.be/SGQdSnvGSck
Cylinder #6
https://youtu.be/fkWtZIiAyto

And this is what you get on your scope when you bottom it out in cylinder #1


So tomorrow these are my plans

Disconnect all wiring harnesses
Disconnect all accessories and remove
Disconnect exhaust

Any other suggestions on what else to look out for when preparing to remove this engine? Any pro tips? Also is it absolutely necessary to remove the hood to get enough clearance to take the engine out over the radiator? Looks like I'll be doing most of this myself so any tips would be greatly appreciated...thanks!

Also forgot about the issue with not being able to turn the engine over manually...so after I turned off the engine when it made the sound, I went ahead and moved the jeep around so when I pull it I don't have to drag the engine crane through grass...so after I pulled all the plugs, and did all the previous videos, I figured out a way to hang the scope down in cylinder #1 and I was going to turn the engine over manually like I had before. Problem was while recording the video I couldn't get the engine to turn at all with my breaker bar like I had before, and this time all the spark plugs were out so I figured it would have been a cake walk compared to when I did it will all the plugs in, but I never got it to budge....but as you can imagine me struggling to turn the engine you can see all the sludge moving back and forth above the piston...

Yeah cyl 1 deff is getting coolant thru it. Plugs burnt from running hot. Same at plug 5. 3 didn't look too bad then the rest looks like a ton of carbon build up from an incomplete fuel burn/oil contamination

Re: Rebuild or replace 3.7l

Honestly I'm thinking about removing the radiator, condenser and oil cooler as well, and just having all that space just to drag the engine out without having to go above all said components...I honestly think I'll be replacing these just to be on the safe side since the jeep did have some front end damage...

Re: Rebuild or replace 3.7l

Quick question for you guys since I'm new to the jeep stuff...so my jeep is a wk and it is 4x4, I was looking for a replacement shifter assembly, and so far I've seen two types...one that is described as for 2wd which looks like mine

and the other thats described as 4x4 and has the little buttons for 4high and low



And this is a photo of mine...


So I'm kinda confused is there specific shifters that dont have the high and low but are meant for the 4x4 models? Because the one listed for 2wd is an exact match for what's in my jeep..

---------- Post added at 05:45 AM ---------- Previous post was at 05:03 AM ----------

Tomorrow I will start a build thread on my Jeep, I'll probably include some of the stuff already in this thread. But I think it's time to move it over to a build thread, since we will be getting more off the topic of rebuilding the 3.7, as time goes on...so look for it tomorrow at some point, it'll be called Project "Rock Bottom"..

Well if yours is 4x4 and does not have the 4lo. It's likely full time awd. Which there's nothing wrong with that. Mines 2wd which for my project, simplifies things.

I do like the name for that build, matches the backstory on the jeep.

Re: Rebuild or replace 3.7l

Is your shifter bad or just grungy looking? SOS pad will bring up the chrome trim like new. Let it do the work.
