On the top of the valve cover are two valves for the CCV system. On Napa, I can only find a "PCV System Elbow", which looks like it only matches the bottom valve (the one closest to the front of the car). Is there a significant difference between those elbows, and are they even both CCV valves...

New member here and first time wrangler owner 1988 YJ with the 4.2l, 3spd auto, nutter bypassed, Webber carb (not sure of the model but not the 32/36) When i first bought the Jeep it ran poorly, needing to double pedal just to stay running at stop lights. It was running very rich at idle...

I was wondering if anyone has relocated their proportioning valve from the frame rail to a bracket suspended off the brake booster/master cylinder. My exhaust current runs uncomfortably close to the wilwood that was installed and I am not a huge fan of that. If anyone has done this, do they have...

i have a 92 jeep Cherokee with the 4.0. 245** miles its making a knocking noise, i sounds almost like a ticking. dosent go away when it warms up or when i give it some gas. i cant tell if its coming from the valve train or the pistons, but it definitely sounds like its coming from the back...

I had been getting an EGR trouble code (I forget exactly which one it was) on and off periodically. So I replaced my EGR valve and the code went away for a few weeks. Now the light has come on again and I'm getting P0401 - something about insufficient EGR flow. I don't know if the new EGR...

Hello, I search propotioning valve for my 98 TJ with ABS, according to the part list, I need the part 52008549 but it is'nt found :( i find only the part 5083807AA for TJ 01-2005 with the rear brake discs option...

Last summer our '06 stem decided to disintegrate and I ordered 3 separate stems and repair kits trying to fix the problem, none of them worked so I ended up buying the entire assembly. ..which of course I should have done in the beginning. Like Clockwork, a second one just broke a week before...

I know the 4.0s are noisy engines, but I've got some pretty significant valve chatter. It's a loud rhythmic tapping and sounds louder than my old XJ with the same engine. I also failed smog for NOx levels being too high, which means that it's burning too hot and lean, so the timing is almost...

I am the lucky recipient of a dropped valve seat. Since I am having to replace the heads and pistons I figured I will go the extra step and do a complete rebuild. This is the first time I have messed with the 3.7L engine. Are there gotchas I should be aware of prior to going forward with my...

I have a 2000 Jeep Wrangler with roughly 160K miles. Recently I let it sit for a week and after sitting, I cranked it & it had developed a "tick noise" which sounds like it's coming from the top of motor or the front of the motor. I changed the oil & added 1 quart of resin to it, but the "tick"...

I recently bought a 78 CJ& with a 258. I got it from a guy that was tired of working on it and the thing sitting in his garage. I new it did not run quite right when I got it. After further inspection I realized that there was a gm throttle body on it. There is also air blowing out of what...

Hello, I have a 97 2.5L TJ with about 119K miles. It has developed this rattle on start up. Many times it takes about 15-30 seconds before it starts making noise, then slowly it gets louder and louder until the engine warms up. It mostly goes away after the engine reaches full operating temp. I...

My 4.0 in my jeep has always ticked. I've also read through many of the threads on the issue. Being a previous owner of a cj5 and all the noise the engine made I haven't paid too much attention to it, since it runs just fine. But recently it seems to be getting louder to the point I notice it...

I regret doing it already, sending her to the shop instead of giving it a go myself. Without going into excuses for that, humor me. I'm also wondering if driving it with my suspected diagnosis has caused other problems. The shop hasn't gotten back to me yet, but here are my symptoms: This is...

So my TPMS goes off to say I have low pressure in one of my tires, again. I go to check the pressure so I can air up and, as I'm unscrewing the valve stem cover to press on the tire pressure gage, the last 3 threads of the valve stem break off in two pieces in my hand, exposing the release...

Hey guys, I'm new on the forum and fairly new to jeeps, and I have a few problems I need help with. I bought a '79 CJ7 as my first vehicle (I'm sixteen, by the way), because I wanted something different that is capable off road. In hindsight, it maybe was a poor choice, but anyway, I have it...

Im having some trouble finding a roll over valve although i saw one on here for a delorian and the guy said it would work. im wondering if the new aluminum racing roll over valves would work?

Got a broken valve spring on a 03 Liberty :mad:. Now trying to find a valve spring compressor to do the job. The pretty unique configuration of the V6 and the lash adjuster are narrowing my choices. Does anyone know what type of tool would best fit the job and where to get it?

I can hear some ticking sound coming from the engine only after I shut the engine off. I recently replaced my valve cover gasket but can't think of why this would cause the ticking sound. I also made sure to cover the engine with a towel after I took the valve cover off when I was changing out...

Been experiencing some minor surging for a while and then the engine light came on. Stopped in to the local auto parts place and they told me it was the EGR valve and sensor by their code reader. I didn't get the actual codes. They looked it up and told me they don't have access to...
