 Subject: Noisy Lifters?
IP: Logged
Message:
Any suggestions on reducing valve train noise? I've tried replacing the lifters, pushrods, and all of the stock rockers are torqued to spec, no adjustment needed. 100% sure it's not the injectors.
Using KRC210 Cam with 2.02 R/T heads, are valve springs to hard on lifters? Using 10-40W Oil
Noise increases with RPM.
Noise increases with heat.
Noise still present when cold, just not as bad.

Are you 100% sure it's the valve train and not the timing chain? I'm supposing you've got a few miles on it if your already replacing stuff like that... did you replace the timing chain when you did the cam?

Only 30K on the engine, nope didn't replace chain. So your saying a loose timing chain can cause that much noise? Wouldn't the timing chain be taunt under increase rpms that would make it tight so it wouldn't bounch off anything and make noise?

No, under higher RPMs the chain will tend to 'slap' more. The chains in the Dodge engines are prone to excessive and early stretching. If the noise seems to be coming from the front of the engine more than anywhere else, it's probally the chain...

Oh yeah... or the tensioner. :0)
Either way you've likely got some timing chain slapage going on. If you have to take it apart, might as well get a better one. Shouldn't cost much more!
Ah... those last two sentances... auto-hobbiest creed!

If you have only 30k on the beast, then why are you not taking advantage of your 3/36k warranty and have the Dealer resolve your prob? I know that dealers can be uncooperative at times, but at least get it in and on record in case of major failure you can be covered.
my 2 cents.

I have a new Dakota with 10,000 miles with the V8, 4.7 engine. I start the engine in the mornings I get lifter noise and after it warms up the noise goes away. I assume this is not normal. These are not cold morning as I'm in Fl.

Why bother with a warranty repair on a timing chain? They'll just repace it with the same thing, and it'll wear out even faster under the heavier loads of the stiffer springs, etc. Yeah, I know it's a cost issue. Get a double-roller timing set and no tensioner. The double roller would eat it up in no time. You can use any set for the 318/340/360 from 1967 up. Not much more than a factory cheapo, but much better, especially in performance applications.

The whole reason for the tensioner is to take up slack to keep the timing tight for the fuel injection system. While the OEM unit is better than the pre fuel-injected units, it's nothing to crow about. And if you look in the FSM, it still states the thing should be replaced at 50,000 miles. Anybody do that? They have to stay relatively accurate for 100K now, and that's what it accomplishes. The OEM unit is gonna stretch out quicker than a high-quality double row, roller unit. Using such a good unit will stay tight much longer. I ordered one of these tensioners and intended on using it til I saw it next to the double-roller chain. The OEM is smooth-edged, but the REAL chain on the aftermarket unit would eat that sucker up, so I wouldn't use it. The friction surface wouldn't last very long.
The tensioner does not replace the thrust plate. The tensioner is built into the thrust plate, so the entire assembly is a bolt-in swap. Either way, a thrust plate must be used.

Cool. That saves me spending an extra $30 for the tensioner then when I order a double roller this week.
