Subject: 4.7L Ticking at Start-up
IP: Logged

Message:
My '02 QC has had a slight tick at start-up for a couple months now. Can't tell if it is valvetrain or bottom end or even a pulley bearing or exhaust header leak - echoes all over like mad. But it's just real faint and only lasts about 20 seconds. Anyone got any ideas on this one?

It seems that a lot of 4.7 engines develope this tick over time and mileage. I've been told that it is the valve lash adjusters not quite doing their job. The other thing is if you are running a crappy oil filter like Fram then you might hear a ticking because the anti-drainback valve is inferior. I only run Wix, Mobil 1 or Purolator Pure One filters on my 2000 4.7

I was thinking it may be a valve noise. I'm gonna have to break out the stethoscope to pinpoint exactly where the tick is coming from. It's definitely not the drainback issue - I've been running the Napa Gold filter since day one. Oh well, she's paid for, so I guess I'll just drive her til the tick turns into Ka-Boom! :oP

Sounds like a lifter to me. No big deal yet.
Try doing what dude suggests and see (hear)
what happends.

I had a old 318 that had lifter noise at start
up. At oil change time I used one quart of
Reslone (not sure of spelling) in place of one
quart of oil... That always did the trick for me.
I *think* it's still on the market.

Thanks guys. I probably would have never thought of it myself, but, come to think of it, the ticking seemed to present itself at about the same time I switched from Redline to Mobil 1. Interesting. I'll get some Redline this weekend and see what happens. I'm always a little hesitant to try additives, but, as a last resort, I suppose I could try Seafoam and/or Reslone - they both seem to get a lot of good recommendations. Thanks again guys.

I have run Mobil 1 oil combined with purolator pure one / wix filters from the outset since my 2000 QC 4.7 had 5000 miles on it. I developed the ‘ticking’ that some 4.7 owners mention at about 45K and now have 84K on the truck. I switched to Amsoil at around 75K and after around 3-4 K miles, the tick went away.

Feels like it must have been the oil that resolved the top end tap.

And no, I am not Stan, Steve, Fred, George or whoever else seems to be involved in many of the oil postings (I simply bypass the flames). Just my real life experience that in my example, changing brands to Amsoil seems to have eliminated the tapping that was previously present during the first 3-4 minutes on a cold start up. I have used Mobil 1 for many years in numerous vehicles and was surprised by the results. I am certain Mobil 1 is exceptional oil, but in this instance the tapping subsided after changing brands. Just one persons experience.

I have an 01 with a 4.7. It ticked at 50k and now it has 134k and still ticks. Runs fine, trying to get ticks out of this engine is pretty much a fool's errand.

hello all , i live on Long Island n.y. and i just bought a 2002 dodge ram w/ a 4.7L v8. Reading the posts it seems that the 60,000 mile marker is the trigger on alot of this cold start clicking. Mine does the same exact thing!!!! I noticed this 2 days after i bought it. Runs perfect other than this annoying noise then fades away after a minute or two of warm up time. does this engine have hydrolic lifters? i have 59,000 miles and am about to put an extended warranty on this truck reading all this reviews..... anything i should be worried about?? please respond....

I think this is caused by lack of oil pressure at start up, caused by a dirty oil pump pick up screen. I have the same problem but am not going to pull the oil pump unless I ultimately have to.

You can try running a bottle of Seafoam, as thats what works for me for a few months until it comes back. My truck has 173,000 on the clock.

The other thing you can try is drain your oil from the oil pan and put the plug back in. Fill the crankcase with kerosene. Start the car and let it run for about 40 seconds. Then let it sit for about an hour, drain and do a fresh oil change.

A tow truck driver taught me this trick and was very skeptical at first but he was right. The kerosene cleans out the crap clogging the oil pump screen. You will definately see some engine improvements doing this on higher 115k mile vehicles.

Hey Al, I have a dodge 2000 Dakota. Does your post mean I use 6 quarts of kerosene like I would with a regular oil change?Then run it for 40 seconds?

I wouldn't use the kerosene, that could easily destroy bearings in the motor because of the inadequate viscosity. if you want to clean your engine swap the oil out for a few quarts of ATF. the additives will clean out the junk and the oil will maintain enough oil pressure to keep from destroying your engine, just DONT DRIVE IT. run it for a few minutes and then drain.

Fyi, my 02 4.7 has a small valve tick at start up, its not going to hurt anything, the oil just has to make it to the valve train and then it goes away.

Bought my dakota new in 02 with a 4.7 developed a tick in the right side (passenger side)of the engine. Apparently the engines have a oil supply problem to the hydraulic lifters.A dodge mechanic told me that the best thing is to find out which lifter is ticking and replace it. On the 4.7 it has a overhead cam,the lifters are under the cam rocker below the valve cover. I replaced 2 and the noise is gone.The lifters are $16.00 a piece from the dealer. Took one hour to replace. Find bad lifter,remove valve cover,loosen rocker arm,remove lifter and replace, torque rocker,replace valve cover. Make sure to put the new lifter in cup of oil and pump it up with oil by working the piston in the lifter.

everyone it is your exhaust manifold guarenteed.More than likely drivers side rear maybe rear two. cross pipe puts pressure on the headers. as is warms up they seal. I did it twice two my 04' 4.7 second time I cut the cross pipe and installed a import flex piece to eliminate the side pressure.

It can be the exhaust manifold as well BUT the lifters do tick. My 05 4.7 broke two exhaust manifold bolts on the passenger side. I fixed that and thought my ticking at start-up would go away but its still there. Just like everyone else ater 1-2 mins of warm up it stops.
Been using Pennzoil Ultra for a while but im going to switch to Redline, if that doesnt do it im going to look into replacing the offending lifter(s)
