What would u do?????

[unclewbbl]

I have a 85 cherokee 4 banger and the same thing happened I pulled
the #2 and it was broken & bent at the electrode,
I thought great pieces in the cylinder chamber tried fishing out and
nothing came out I even removed the oil pan and checked for metal
still nothing put all back togather w/ new plug and did a compression check on all cylinders and had #1 150p.s.i #2 130 p.s.i #3 150 p.s.i
#4 150 p.s.i then started motor and sounds like I have a sticky lifter
but still runs half way decent.
I dont know what to do next, Thinking about doing engine swap
to a chevy v6 f.i. any help would be great

Wow....you removed the oil pan? Isn't that a lot of work?
I dropped a washer down the carb one time and it went in the chamber and smashed the spark plug, but I was able to fish it out with a magnet and it ran fine after that. You can take the head off and see if part of the valve is burned off.
Recommend you get a later model with the 4.0 liter 6 cyl. engine.
It won't fit into your chassis, and the GM 2.8 L that came on that year (85) is TERRIBLE (i HAD ONE). Wimpy too.

Yeah I thought I dropped a washer down the intake manifold right before it started knocking real bad, but later I found said washer on the floor.and i tried to fish out the spark plug hole with small magnet.
I got no metal pieces at all thats why I removed oil pan. I read somewhere on a post that the chevy v6 3.4l would bolt right up to my 5 speed trans.

Take the head off, it's not that hard. Washer or "parts" are probably in the "squish" area of the chamber. Then evalulate your situation. Hope fully nicks in the piston or head are not that bad.

I don't think the 3.4 will fit in the compartment. How about headers, steering clearance, wiring, vacuum controls and clutch linkage issues???
What about the shape of the oil pan where the front part of the 4wd goes. The 4.0 L Jeep is much better, I have two, a 97 4WD 2DR Sport and a 2001 4DR 2Wd Sport that my daughter uses. Got rid of the 84 with GM V-6 engine because it leaked too much. Overhauled it once, cost $2000 because you have to replace the crank to use a one piece seal.

Will the 4.0L fit in the 85 compartment with out much hassle, also would i need to change the wiring harness what all would i need to get with the 4.0L , Because sunday is half price at junckyard ( I''m not saying I'll buy everything there.)

Sorry...the 4.0 L will NOT FIT into an 85 chassis.....Jeep changed the body for it to fit. Buy a newer body with the 4.0 engine in it.
PS, I was a mechanic for 25 years.

Well I've only been a mechanic for about 6yrs . So I'm still learning
You also said the chevy v6 60 degree fuel injected motor out of a 1990 - 1995 camaro or s10 piickup or blazer woint fit either.

The Cherokee came stock with the GM 2.8 liter V-6 in 84 and 85 and it was certified and everything in a Jeep Cherokee. Yes, the 60 deg. V-6 will fit, but the stuff might not be the same...(like compression ratio) ...get it....they do stuff to it that makes it different. The Jeep one had an electronic carburetor...and I think the Jeep 4 cyl was rated at 1 HP higher than that motor which is 125HP....the Jeep 4.0 is rated at 190HP and a lot more "torque". Try drive a 4.0 and compare.

Now....if you really what something different and you are a good welder and fabricator.....try the light weight Buick V-8 all aluminum engine that Range Rover used. They bought it from GM. Good Luck.

Hey...looked at the link....sounds like you want to make a major hobby here.
He is doing a V-6 to V-6 conversion. You have a four banger.
Also 3.4L is still smaller than 4.0L (the Jeep engine).
If you read the forum, you will find the 4.0L is renown for power and reliablity in the factory form and chassis. So basically, you have to do nothing except find a new (used) Jeep XJ (Cherokee) with a 4.0L engine and 4WD for cheap. I was much impressed at one time when my '79 Corvette got "smoked" by a 4.0L Cherokee. He was probably running a stick while I had the automatic. I recommend the 1997-2001 XJ body because of looks. You should be able to keep this new truck for a long time.
