I have an intermittant problem with a "lifter type" sound coming from my engine. When it does 'tap', it also feels & sounds like it's missing. Then, just as fast as it started... it goes away and runs fine. Then wiyh in a few minutes it starts over again. Is it possible that it could be a...

I just changed my fuel injectors. I was having an intermittant problem with one of the old ones. I picked up a known good set locally. They are out of a '95 4.0. I put them in my '93 4.0. The Chrysler part numbers are: 1993 (white plastic plug area) #53030343 removed. 1995 (orange plastic plug...

Mine has 275K on it and when I got it, it had 225K on it. Yes mine is VERY noisy. But mine does it cold. Once it gets nice and warmed up (the oil not just the water temp). It is quiet as a brand new motor. I believe it is piston slap. It has had something that sounds like a lifter happen now...

I have a different year XJ but, I was told that after shifting out of 4WD to make sure it is disengaged, stop, back-up a couple feet, then drive on. It works for me, but I have a different transfercase.

It's a '93. Michigan... below freezing. Restarted within a minute or less. I am trying to get my signature to work!

I have cold started my XJ and had to turn it off just there after for one reason or another. When I go to restart it acts flooded. I have to floor it to get it to start. Once started I need to pedal the accelerator to clear the fouled out plugs. Once that is done, it runs fine. But I know...

10 yrs ago I worked at the now defunct Autoworks. We sold the plugs there. The only thing I saw was the truck plugs looked prettier. Theyre supposed to be more durable, what ever that means. I go with the regular Champions. They're inexpensive and since they're easy to change I do it about...

Has anyone else found this to be true... about the O2 sensor etc. Sorry Jeep914X4.

Is there a part number on the pan? Maybe the wrong pan! It happens duing regular driving? Are the bumpstops still there? Are your springs shot?

I've used MMO, Lucas, Amsoil, Rislone(sp?) and several others (stp etc.) Tranny fluid/oil flush. Kerosene/oil flush. Amsoil full synthetic oil to WalMarts house brand oil and filters. Casite $1.99 filters, Fram and K&N. My XJ has close to 275K on it and rattles the same either way. I must say...

I get a "lifter type" noise engine cold or hot, but it's intermittant. At an idle it will be doing it, then suddenly stop, then start again. Sometimes it feels like it could be missing too. Strange thing is, when it's making the noise, I will shut off the motor and turn it rite back on and it's...

I put a plate and bolt thru the hinge. I didn't need to remove the door, but it was really tricky getting a nut on there. Once I tightened everything up, then I put a weld on the back of the hinge with my stick welder. The door checks no longer worked on my XJ. I had an old broken nylon...

The cat was the problem. There was a "ball" shaped piece of the brick in there a little bigger than a fist. I think when the flow got high enough the ball would roll to the output and work like a check valve! All is well now! Thanks ALL!

275,000 on my '93

I think I'm gonna do an "exploratory surgery" on my cat converter tomorrow... with my Saws-All, weather permitting. I'll let you know of my findings. Thanks
