yes chevys 3.4 and 3.5 have common lifter noise, have you checked the oil level. I would a better oil ,and I put lucas oil treat in my customers cars after oil changes
Usually a sign of needing an oil change. My Dodge Dakota does the same thing, when I change the oil it goes away. Every couple of oil changes I use kerosene to clean out the gunk, just put kerosene in place of the oil, let the motor run for a minute then drain, replace the oil filter, and fill with oil, then you're good to go.
this engine has forged pistons whitch expand more than hyper-u-tec-tic pistons when heated . this is normal for this engine . my brother has a chevy silverado 2001 1500 4.8Lwith 650,000 kms and he said his made that noise when it was brand new and the dealer said this is normal. the truck still runs like new with lots of power and it still makes that noise before it reaches operating temp then goes away.My brother uses lucas oil treatment and it helps quiet the knock a little when cold.
This sounds like the hub bearing.If it stops when you turn right then it is the right side front.When you veer right this takes the weight off the right side and the noise goes away.If the noise comes back and stays there when you veer left then the weight of the vehicle is on the right side.Hope this helps.Good luck.
how is the oil level and pressure?, how many miles on engine? is this a loud knock or rather a clatter/ticking noise? knock is engine rod or crankshaft bearings, clatter loud ticking is valve follower noise. how long before it (the noise) goes away?
The whine sounds like the power steering or the alternator, as far as the idle issue goes try this clean the intake throttle body and idle speed control valve with carb spray, disconnect battery for 5 min. then reconnect and drive a few miles to reset idle strategy. The car will try to die when you spray the intake, hold the idle up to prevent that, use at least 1/2 the can of carb spray.
