Hi y'all doing, im new to this forum and im hoping you guys can really help me out. I drive a 99 dodge ram 1500 5.2 2wd, I put in a rebuilt trans about 2 months ago, and when I pulled it out my brother forgot about the crank sensor and ripped it out OOPS! I put a new mopar one in and ran beautiful, now heres the problem I for the past month the truck has been making a ticking noise, one day me and a friend were messing around doing some donuts ,and now the problem is worse. The truck sometimes ticks when its cold, but does it all the time when warm, doesnt matter what gear its in, at a stop light just sits there and tiks, and chugs when i start to pull away. The tik is only sometimes and is a tik..tik.....tik.tik.tik.......tik somewhat of a pattern. Kinda thought it would be an injector, any help would be very apprecated! Thank you

 

How is your oil pressure? How is the oil level? Have you had the plenum fixed?

 

Can you correlate the ticking to engine vacuum -- does it only come along when vacuum is high, and go away when vacuum drops a bit? If so, catch it when it's ticking and poke the PCV valve with a stethoscope. It might just be a cheap, easy fix.

If that's what it is, get the new part from the dealer. The aftermarket parts are terribly hit and miss and a miss can cost you a lot more than the few bucks you saved.

 

I changed the oil last night, got good level and pressure, what do you mean had the plenum fixed? And for unregistereduser I dont know how to check that. When I listen to the tik its coming from the top of the motor by cylinder 1.

 

Okay... try this: Next time you hear the tick, notice what the engine's doing at the time. Is it just cruising along on flat ground maintaining your current speed, decelerating, or working to increase your speed, climb a hill, or fight a head wind? If it's one of the first two, briefly accelerate gently and listen to determine if the tick disappears until you let off the pedal again. If it's one of the last three, let up on the throttle to determine if the noise goes away and then comes back when you depress the throttle again.

If the noise is present when the engine is loafing along and goes away when you depress the accelerator pedal gently, it's probably the PCV valve.

If, on the other hand, the noise is present only when the engine is working harder, and goes away when you let up on the throttle, it's probably a small exhaust leak.

If throttle position, engine vacuum, and/or load make no difference at all, it's probably valvetrain related.

 

Thanks ill try that the next time out. But heres some more info about the problem, its not a constint tik, it only does it at a stop when its warm. When I take off from the stop it chugs until about 20mph. When it tiks it shakes the truck like its grabbing something, took off the inspection cover, started it up, looked at the flywheel torque converter and saw nothing it was hitting.

 

could it be an exhaust leak from the trans swap?

 

I never took off the exhaust for the trans swap, but good question seabass.

 

Well I tried what ya said, and it didnt tik very much when I was driving. Drove it to autozone and had it scanned, came up with codes P0301 cly 1 misfire, and P0740 which came up as tcc, can you help me with the tcc code also? So with code P0301 and new sparkplugs, wires, and cap, could the problem be injector #1 where I hear the ticking coming from??

 

The p0740 is most likely the result of a faulty TClockup / OD solenoid assembly.
