Running Hotter and Losing Coolant

[WILDHOBO]

Confirmed by inspecting spark plugs and then even more so by borescope... Head gasket failed around cylinder 4. Expecting to find cam wear when I pull the valve covers. I'll have to decide if I am fixing what is broken or just putting a new engine in it. Lovely.

Oh shit.

Dang man So sorry to hear that. I was hoping thermostat

Yeah that sucks.

The inner cam on the driver's side is worn on the rear most lobe. Where should I get a kit to replace the valve train that is improved over the 2020 design?

Wowza. How many miles?

 

[Chadnutz]

125k. Passenger's side crapped out around 57k and they replaced worn components under warranty.

If it were me I'd just buy a long block rather than mess around trying to replace parts.

I am also considering that, but I need to know that the long block has the latest head gaskets and valvetrain. The fact that I am having to dig this far into a 6 year old engine is ridiculous. This is the first new vehicle I've ever owned (bought at 39 y/o) and the worst in terms of engine robustness. Passenger side cam shafts worn enough to throw a code back at 57k. Now both intake cams are worn at 125k along with a blown head gasket. That means the passenger intake cam has failed twice.

I really love the vehicle. This just blows. How am I to know it won't happen again? Has anyone ever pulled their valve covers and not found cam wear?

Your experience makes me want to…very hard to verbalize this, change my head gaskets proactively at 86k.

@WILDHOBO tell me about it.

I have to wonder, with all the heat soak issues is that the cause of these blowing out prematurely?

I ask because My 2G 4Runner had the infamous 3VZE head gasket replacement because of heat soak up against the firewall roasting it.

I’d be willing to tackle it if it’s not horribly risky. Along with the oil cooler/filter assembly. Those haven’t failed on me yet, but I do all my changes and am very careful with hand tools.

I wish you would have reached out to me before you cut the tank in half…I would have flown down to your place and we could have had a tank cutting party, it would have given me extreme pleasure to take a band saw to yours and my POS, leaking, proprietary bottom fitting (it leaks as well), unbelievably horrible designed coolant reservoir tank, with the worst possible selection of plastic materials that goes to full brittle with the coolant temps that run at near surface temperature of the sun.
If anyone from Jeep is reading this…focus on this for just a second…quality of materials matters! Aluminum Please, Geeze. Oh, one more thing, lose the POSP cap. Jeep, make or source these out of metal as well. You’ve been doing it since 1941 for hells sake, wake up and work on your customer satisfaction numbers. 85 years of this product line…your customers expect better.

Jeep's engineering department answers to the bean counters instead of the other way around. Same thinking is what ruined Boeing.

I sell used jeeps with milage from 95k to 160k have done 20+ top ends cams lifters and gaskets and some valves have not had any comebacks after sale of jeep most terms 36 months customers still no problems cost for me is about $1800 out the door my labor rate is $75ph because its dedicated shop,if it was mine i would do topend..IMHO

Where do I get the parts? Jeep?
