Squealing noise coming from left side of engine.
I've replaced the following.
1. Idler Pulley 2. Serpentine Belt 3. Spark Plugs 4. Camshaft Cover (Valve Covers)
See if the noise goes away if you remove the oil filler cap, if it does it is the crank seal. Was the valve cover PCV bad?
And he needs to follow the TSB to see if the intake manifold boost check valve is still there.
Yes agree.. Thats why I was asking if there was a issue with the valve cover or if it got replaced just because.
I'm pretty sure GM has a special policy on at least the valve covers. I refered a friend to our local gm dealer for the valve cover and they did the intake too at no charge.
youtu.be/2Dk15ut80XM Watch about halfway through after you hear your noise….
Probably need to replace the valve cover again and this time the Intake manifold as well. Remove the oil cap whn its running to see if the noise goes away.
Most likely it is the front crankshaft seal , very common thing , someone mentioned already,
