Engine Ticking Noise

[chevelleguy]

My 07 with 12,000 miles has made this noise since new. Doesn't do it all the time but it does especially on cold starts.

Yeah, my guess is it having something to do with the EGR when it is warming up.

Mine also has it - When I can hear it over the diesel "clatter" - no problem so far.....

Mine ticks from 1500 to 2200 rpm or so, is it the same thing? I really hear it when driving by parked cars or jersey walls. I hate the tick so much in my LB7 I want to sell my truck for an 04 or 05.

I just noticed my 05 makes the noise, so you better check it out before you buy

Sounds like "typewriter"-- Normal Dmax noise- no worries.

I have an 04, it does the same thing, have read many posts, one said the oil gets bubbly and its the bubbles popping when pushed back thru the system because of the high oil pressure in the 04, I run at about 70 p.s.i at 70 mph ?? thats what is said, I have not had any problems with mine as of yet and all post I have read say not to worry, its inherent to the motor. Nothing I have found says its a problem

I know this is a old thread, but my truck had never made this noise before. But now that i got it back from the head job i am getting this noise. However mine is on the passenger side of the engine not the drivers. Would this ticking be the same noise that everyone else is hearing on the drivers.
