Question about Jeep Liberty

2 Answers

I pulled my valve covers on my 04 jeep liberty 3.7 and both sides have a rocker arm that has slipped off. there doesn't seem to be any damage done, but i have yet to pull the heads off. what should i look for when i pull them? i assume the valves are stuck open but i've never dealt with a problem like this. are there any links online that i can find the parts and prices or atleast a discription of how to tell if anything is damaged with the rocker arms and valves?

Hi, without a rocker arm, the valve would stay closed. As the lash adjusters may have been loose for a while, check the camshaft lobes for wear as well as the rockers themselves. Look around for other stuff the rocker may have damaged while bouncing around in the valve cover. Replace all of the lash adjusters, making sure to put the rockers back on their original valves. Not sure you need to pull the heads. Why don't you put it back together and run a compression test. If compression is good, valves are probably fine. Let me know if you have more questions, and thanks for using FixYa.

If your rocker arm has come off, there should be no damage. the rocker arm opens the valve when the lifter pushes up on it. the valve is closed. you may have flooded pistons, depending on if it was the exhaust valve. you could try remounting the rocker arm first, and test with the valve cover open. this messy, but will work. to see if you hear anything. if this works, it will save having to pull the head. if the valve was bent, to find out, just depress the valve, and see if it pops back up. it should be at the same angle as the other valves. hope this helps, let me know. twoduckster

3.7 rocker arm fell off


The 3.7 and 4.7 in these years were known for this . If after reinstalling the rocker you have a bad miss, check compression on this cyl. If you have zero then the valve seat has dropped (common problem) This causes severe engine damage and parts to repair this are very expensive

I HAVE SAME JEEP SAME PROBLEM...I have found out after research that all these jeeps like yours and mine have a common problem with engine clogging and the valves sticking and the rocker arms coming off.....This is true I pulled my valve cover off and the rocker arm had come off because the valve was stuck ....Pressure between the rocker and the cam and the valve is the only thing that will keep the rockers from falling off......And when the valve starts to stick the rocker falls off.....This is sad but true.....Also it is badly clogged with black chuncks of burnt oil....I dont know what causes this other than the wrong weight oil....but I only used the wrong oil maybe 2 times...
There should be a recall on these because the rocker arms shouldnt come off.....I think the rockers are wrong from the factory....I am a level 2 chrysler tech.and also ASE certified.......It makes me angry that they built these so weak !! ....All you can do is remove the heads and have a complete valve job done and clean the oil pick-up tube in the oil pan as well....then a complete engine flush..
.....ONLY use 5w20 weight oil also........If you dont have the cash dont tear it down cause I almost guarantee you have the same problem as I.............Hope this helps.................Metalpoet

03 jeep liberty 3.7 liter v6 the rocker arm keeps coming off and it has an overhead cam wondering what all could be the problem


most likely (as seen in my experience), the valves become slightly bent & they don't travel properly within the valve guide, causing the valves to stick open. It will almost appear to be a broken valve spring. I've seen a handful with this problem. The valve sticks open & the cam lobe doesn't even touch the rocker arm, thus "tossing" the rocker out of position.

2002 Jeep Liberty Sport 3.7L V6 Replaced all six spark plugs with brand new ones and replaced coils for 4 and 6 with new ones Still reading misfire Within 10 minutes of starting enging, vehicle idles...


We have an 02 Liberty 3.7L, here at my repair shop, after customer replaced, spark plug's and all coil pack's, brought it here to my shop, was running with two cylinder's miss, did cylinder compression test, no compression on two cylinder's, remove valve cover's, found two rocker arm's off, remove cylinder head's, and found that on those two cylinder's the valve seat's had drop, keeping the valve open, and that's why the two rocker arm's had come off, do a cylinder compression test, could be the same thing, hope this was very helpful.

Will the 87 2.5 chevy engine bend valves when the cam gear strips ?


I have worked on many of these with this problem, I best answer is; that while they can bend valves I personally have not seen it happen.....yet.
You can pull the valve cover and see if the valves look even to each other with the rocker arms off, or more quickly check if any of the rocker arms seem very loose without removal .

Rocker arm come out on jeep chrysler 3.7 eng


A rocker arm is the arm that sits on top of the valve stem and connects to the push rods 'the push rods sit on the cam so when engine is running, the push rods go up and down in a timed sequence and with the rocker arms, open and close the inlet and exhaust valves. the rocker arm is located inside the valve(rocker)cover .If the rocker arm gets loose or comes out.
Check the nuts on the shaft which holds the rocker arms.either the shaft or nuts are got loose.They need to be tightened.Don't make it too tight or too loose.  Too tight,and they don't flutter right. Too loose,and they allow the rocker arms to wiggle out of whack. Other possibility can be  something is broken, bent, collapsed, or out of adjustment. 
Thanks. you can rate this solution and show your appreciation.

I have an 2002 Jeep Liberty that keeps throwing rocker arms. Has anyone else had this problem? We have replaced lifters, rocker arms and valve springs any ideas? This always happens on cold start up


yeah it needs a new cylinder I see this all the time. The valve stem guide in the head drops and sticks the valve open the rocker and cam lose tension and thats why the rocker keeps breaking. Take the valve cover off the head that your have problems with. remove the rocker put a socket over the valve spring. gently tap the spring down without loosening the keepers. You will notice that the valve will not return to the closed position. I garuntee this is the problem u r have I hate to give u the bad news.
