Jeep 4.0L Runs like "Garbage"? (Part 1 - Diagnosis)

This 2001 Jeep Wrangler 4.0L is on its second engine at 379k miles.
According to the owner, it runs like GARBAGE...especially at idle and under acceleration.
It did make it to PHAD under its own power from 4 hours away.
Local shops have been STUMPED after replacing spark plugs and coil pack didn't fix anything.
Cranking it over, sure sounds like at least 1 cylinder is very low on COMPRESSION...
Let's diagnose this Jeep 4.0L and see if it can be repaired, or if it needs ANOTHER engine?!

I seem to remember 50 years ago in auto shop when a SUN scope the size of a refrigerator was hooked to a car you could deactivate cylinders one at a time and see if the idle rpm changed. If it didn't you knew that was the cylinder not contributing. Do modern scanners do that and is that a test that would have identified cylinder 4 without having to disassemble? Your use of bore scope and leakdown test was very definitive. Nice job as always.

I think 20 years ago there was a TSB about getting the exhaust valves to rotate on the 4.0. Obviously too late with this one, but what I took away from the TSB is if you have a 4.0 be sure to get it over 3200 rpms often. That was supposed to help decarbonize the valves and prevent them from sticking and not rotating.

A proper valve job on this run-out head would involve seat and valve replacement, resurfacing, and possibly a multitude of other expensive machine shop processes. This would sideline the vehicle for weeks or months and cost a small fortune. A good used or rebuilt head will fix the problem, so long as the lifters are working properly.

[@jdtractorman7445]

Sometimes what can cause a burnt exhaust valve is a partially plugged fuel injector. It causes the cylinder to run very lean and gets the valve hot to the point of burning a chunk off of it.

The 3.8 litre Buick L36 V6 engine which was Holdens ECOTEC version had the same valve seat recession problem at about 236,000 miles or 380,000 kilometres in his 2000 model Holden VX Commodore due to the use of LP gas which is hard on the exhaust valve seats. His solution to fix the problem was to replace the whole engine which he got from a 2004 model Holden VY Commodore at the local auto dismantlers back in 2017, the engine had done 200,000 kilometres or 120,000 miles in that car To be honest, I don't know why he didn't just replace the cylinder heads with reconditioned exchange cylinder heads, replace the pushrods which were scuffed & possibly the valve rockers as well, there were used cylinder heads for sale on eBay as well. He was worried about reliability but he barely drives the car now because he's always driving his Colorado,he also decided to replace the 4L60E transmission with another one from a VY Commodore as well probably to fix the delay on takeoff that car seems to have but when the VY Commodore transmission was fitted (on the second go because he broke the pump rotor inside of the hydraulic pump because the tangs on the torque converter shaft were misaligned) it didn't make a difference so I don't know if that's GM or Holdens fault. My VY Commodore has a tweaked 5.7 litre Chevrolet LS1 V8 engine & T56 Tremec manual transmission fitted, it's approaching 397,000 original kilometres (247,000 miles) on the odometer,I prefer to drive that car very much more than the 3.8 litre Buick L36 V6 powered Holden VX Commodore !

[@jfv65]

Yep LPG will do that to exhaust valves + seats. Some brands more then others. But it will happen much faster if the heads are made of cast iron with the seats cut straight into the casting (like Ford Pinto OHC inline4). In such a case you can have special valve seats machined in. If i remember correctly the material is sintered steel made by Schneider. I could be wrong tho. It has been at least 15y ago since i had it done. The accelerated wear is caused by micro welding that happens between valve and seat as they slam together and get ripped apart again. Specially at high revs.

[@farmermiyagi1338]

Brother calls me yesterday with an 07 Silverado that has over 75 pounds of fuel pressure. I said need a regulator/pump. He said brand new pump. I asked the brand. He says Delphi. Sorry dude, if you got no FSCM, you got a bad regulator. Apparently it had the same issue with the old pump too. Both banks running rich. I haven't gotten over there yet to check it out.

Good job bro. I think you could remove the fuel pump relay and use the injector pulse as a reference for the compression test

Can you let us know if the head casting no. Is 0331? If it is - is there a TUPY casted under oil filler neck? If not - make sure you get a TUPY unit. Non tupy are cracking, causing issues on cylinder 3 and 4

Nice video of another case study. It will be interesting to see what lurks in the dark to surprise you. It looks like it might have ingested the valve seat on that exhaust valve.

[@user-wu8pb5tk8s]

Retired now but it was common to see exhaust valves receded that far or further on cast iron heads running on LPG in the days of leaded fuel. LPG has no lead, hence valve seat recession caused by "welding" of the valve seat to the head with no lead to intervene. Over time the seat material goes out the exhaust pipe and the valve becomes recessed. The ticking that goes with it is the valve clearance in the "lash" of hydraulic followers running out of clearance. Usual cure was to put inkonel or other hardened valve seats in the head and stainless or inkonel valves in. Since introduction of unleaded fuel and aluminium head the seats are induction hardened or in aluminium heads, hardened inserts.

[@user-wu8pb5tk8s]

I meant welding of valve face to the head.

[@huntnfishnuts5880]

These engines in that year range had all sorts of head issues, they would crack under where the oil cap is and leak coolant into the oil, the valves had carbon issues from low rpm, then they would burn and wear the seats, they had TSB’s for fuel vaporization after a hog soak, the list of issues just go on, great video as always Ivan👍

@@Garth2011they had head issues from 99 to about 2003 then they changed the head casting to fix the cracking issue. They still had carbon issues with the valves though, sometimes you could repair just with combustion chamber cleaner others got full valve jobs with new springs.

[@rickheckbert2423]

Did someone redo that head already and put an undersized valve in it? Not sure how a valve that otherwise looks ok could sink below the head surface. I'd love to see the valve train on that particular valve. Almost like a rocker slipped off but that doesn't fully explain the valve bypassing the seat. Even with a working valve in cylinder 4 that head still wouldn't run too great given those other cylinder pressures. Hopefully a valve job solves the compression issues and it isn't leaking/stuck rings. Thanks for the video Ivan, always love to see a new PHAD's post.

I know these old Jeeps were infamous for dropping valve seats. Usually brought on by overheating issues. The Jeep Liberty with the 3.7 V6 had a bad rap for that. But when a valve seat drops out, mass destruction follows. I'm not seeing that here. So, did this valve seat pound it way deeper into the head? Or did it just burn it away?

Wow, what happened to that seat? Those were actually pretty good engines, but if it was a “used” swap who knows how many miles it actually has. I’ve seen a couple of these with broken piston skirts, which creates a pretty distinctive noise. Very short skirts for whatever reason. Considering the compression on the other cylinders, I would be a bit reluctant to even put a used head on it, but it is of course the owners decision. 👍👍🇺🇸

[@JoelAutomotiveInaction]

I do not like the way how you did the compresión check by removing all Spark plugs 9:07 .

I have a 98 (same Jeep) with 190k on it and I just pulled the plugs to take a peek at It's heath and they are golden! I added an Accel High Energy (Hot spark) ignition coil about 30k miles ago and the difference in combustion is considerable.

Those heads always had issues. I actually remeber changing a few that leaked coolant right through the casting. You could pull the valve cover and watch the antifreeze weep out of the head...flow right down the oil return hole to mix with oil. You would think it would be a bad hg, but in fact bad head/casting. You should check iatn out. Back in the day it was the top place to go to connect to techs with weird issues. Like for example..most older fwd gm cruise would not work if ABS light on.

Hypothesis: tappet stuck, making the exhaust valve slightly leaky. This caused hot exhaust gasses erode away the valve, but not the seat. End result is a recessed valve that is (still) not sealing properly even if the tappet unstuck itself.
