Ticking sound. Sometimes there, sometimes not

I do not want to sound rude or dismissive but I agree whole heartedly. Leave it alone. I do not place too much effort on thinking about what these gauges do. I glance, and move on. I take what they tell me in advisement. Focusing too much on these gauges can lead to a wild goose chase, multiple page threads, and lighten your wallet by $500 or more, for nothing. I've had multiple GM trucks across three different generations and they all do this, bounce all over the GD place. 

 

There sure is a possibility of a weak O ring, or clogged pick up strainer, etc, but you'd see more concrete, blatantly wrong readings. 

 

If your mechanic is telling you not to worry about it, which when you think about it hes turning business away from himself, listen to him. It's not worth it. 

Stu, I agree 100%.  I've moved on, and the ticking has not been heard but once since I started this thread.  Last time out,,,,nothing, just normal.  The mechanic I trust is a real straight shooter.  Christian man.  His whole family is in auto work, he has the mechanic shop, his uncles have a body shop, which I"ve used numerous times over 20 years.  Excellent work from both.  And honest.  Yes, he has turned away work for me twice advising me its no big deal....forgettaboutit.  Thats how he's built his business and you should see his parking lot.  So, in summation I agree, I was making noise when I shoiuld have just moved on -- which I have.  Thanks

I think you can remove just the timing chain cover and replace the O ring, BUT you have to get a lot of stuff ou to the way just to do that. Dropping the axle isn't for the faint at heart, On my 4 X 4 I took of the wheels and tires, the axle on the right has to come off, it's not hard to do it's just a lot. I was in no hurry, I'm retired so I don't HAVE to go anywhere in a few hours so I worked at my own pace. Had a beer when I wanted one, said "NUFF" for today when I wanted to! I cleaned everything with lacquer thinner, ground off casting flash, did a real 1st class job. My Chevy dealer is down and across the road so if I ran into spec issues they were close at hand. Actually I had a pretty good time. That was because I HAD the time.

Oil pressure varies WILDLY regardless of what the gauge says; the oil is sent into a small orifice (hole) from a large (in comparison to the orifice) hole (oil galley) and the difference act a little like a flywheel on the crank smoothing out the otherwise pulsating power from the crank, it smooths out the pulses and give you a sort of "averaging" of the pulsing pressure. Personally I like 40 psi at a fully warmed up idle, all my first cars had so low a pressure it was embarrassing! Stop at a light and the oil low pressure light would glow... my buddies would give me crap over my POS and it's worn out motor....I still loved my 1964 Ford Galaxie 500 XL, with the 4 bbl Thunderbird 390; even the 4 doors, the automatic C 6 tranny with the cast iron case and a factory floor shifter; AM radio with the factory option reverb to the center rear speaker between the back rests of the back seat....retractable seat belts... driver's power seat and manual outside mirror remote control...ignition switch on the left of the dash above the driver's left knee... had a long console between the front seats...we'd fill it with Peanut M&Ms for those long cruises in the cool summer nights when the munchies hit. ahhh youth.....
