arnoldw said:Had the same thing on a '93 Concorde....could have sworn it was a rocker arm, but it was some kind of emission valve near the passenger side valve cover. It was a few years ago but I think it only did it when idling in park. If I gave it some gas it went away.
That's a good possibility Arnold -- a friend of mine had something similar on his dodge van, when he put his hand on the valve he could "feel" the ticking, he replaced the valve and the ticking vanished.
It snowed here, about a month ago, and on that day, just after cold startup my SRT8, made a ticking noise that varied with engine speed. I had hear it before and recognised it as fuel injection ticking noise - it was too fast repetition to be a lifter. When the weather warmed the tick went away and has not returned. Not a fault just a function.
The lifters in the V8s are roller-type and if they have problems and make noise, it would not be a tick - more like a hammering.
Lastly, and most unlikely - unless you've been messing with the engine internals - is a rocker arm touching a valve cover - you like longshots this is one of the longest ever.
Some have said Mobil1 will cure lifter noise. :sgrin: :laughing: :sgrin: :laughing: (evil laughter)
