I've been hearing an audible clicking sound at idle on my wife's 99 Durango (5.2L) for quite some time. I took a screwdriver and pressed the blade over the valve cover and put my ear on the handle, and from what I could tell, it sounded like a lifter causing the clicking. Has anyone else run into this and are the lifters easy to replace without tearing a significant amount of the engine out to get to them?
Possible bad lifter?

Yup my 97 318 does the same thing ever since it hit 140K; but not all the time. Sometimes it hammers hard, sometimes not at all, sometimes very light on decel. Motor is very clean inside, no sludge buildup at all. In 06 I resealed my plenum gasket, and later in the year I put a crank/bearings/oil pump/timing chain in it, that was at 136K; I am up to 141K now. I haven't been driving anything much the last 4 months. Ive been wanting to dig into it and see what is up but every time I think of doing so it gets quiet on me again. Sounds like #4 cyl when it does rattle, from listening close under the hood Oil press is great, another reason I haven't messed with it yet. (even when I'm NOT busted up I don't take the truck much as my Cherokee and Wrangler straight 6s aren't as thirsty.) if I drove it everyday I would be more worried.
Yeah, there has been no visibly noticable effects of the sound. It passed the emissions test with flying colors last time I put it through, the oil pressure is fine. It's just one of those lingering things that I know is going to completely go wrong at the worst possible time (on a road trip with my luck).

I've also had a ticking noise when i start my truck, now it is almost always there. My dad thought it was a lifter at first.
I just added HS 1.7 RR's... i think one is just loose :rant:

I had 2, Dodge Diplomat ex cop cars, an 85 and an 89. Both "roller" motors. On both of em, I'd get a bit of lifter rattle til the heat gauge started to move then go away. *I BELIEVE* that the roller lifters used in these late-LA series motors are the exact same as the ones in our Magnum motors. Sold the 85 with 190K on it when the body started to go, and it still had great oil pressure and would still smoke the tires. The 89, while very dependable was always a thirsty pig especially when I had the 85 to compare it to but they both made the same lifter noise when it got cold out and neither car ever left me stranded.

at start up they will make a little noise, untill the oil pressure comes up, and gets to the lifters to pumpp them up a bit, then they quiet on down.

Does the sound fade away once the motor is warm? If so, then it is exhaust. When I took my 4.7 in to have the headers put on, I was told that 2 bolts on the passanger manifold were missing. I had what I thought was a ticking from the motor, my dad told me it was exhaust, it would fade away once the motor got warm. Stock manifolds were missing 2 bolts @ 45k miles. Wow mopar, you rock!
It doesn't appear to fade away at all. What led me to my conclusion was taking the tip of a screwdriver and placing it on the valve cover and pressing my ear to the handle to see where I could hear it. It was on the driver's side.
Of course, that doesn't mean much, considering it's just sound and you can't visibly see it. With the history of the early Durangos, it wouldn't surprise me if the damn thing was missing half the engine. The vehicle JUST rolled over 100k about 2 weeks ago, btw.

pop the cover off and start the motor.

that may be true, but like mentioned earlier, if the sound would go away it could also be a lifter since it may stop once it gets full oil pressure. The 4.7 doesnt have "lifters" so it couldnt even have the same problem really.

i thought i had a lifter or valve train noise on mine, but it ended up being the little black valve that plugs into the rear of the driver side valve cover, dont know if thats the pcv, but it buzzes and rattles like a SOB. check that, might be it.

i got the same problem on the 5.2L dakota that i'm rebuilding. the only difference is i fired the motor for the first time in 2 years back around christmas.
i'm thinking i have a little bit of a sludge problem as the previous owner seemed a little shady. i do have 1.7 RRs, so i'm going to replace them, the pushrods, and the springs and see if that helps at all.

my dak just started doing the same thing. when it gets to operating temp it goes away, but rev it up and back at idle it'll come back faintly. I'm fairly certain mine is a lifter going out. Check your exh manifold bolts first then go from there

not to sound pesimistic or anything, but i have a 2001 durango r/t and i had a similar issue, mine would tick when you first start it for a couple seconds, and then stop and then it would tick (not loud or severely, sounded just like a lifter) above about 3500rpm. i'm picking it up from the dealer tonight after it got a complete remanufactured long block put in under my aftermarket powertrain warranty because it had 3 bad rod bearings and a bad wrist pin. i bought it about 2 months ago with 94,000 on it and when i took it in it was at 97,000. now i'm counting my lucky stars that i spent the extra $1350 for that powertrain warranty :woot:
