Thank you, I will PM for the part numbers or links from amazon.

Mine, Was probably a bit higher pitched of a tick. I did order new wires, Just trying to get an idea before dropping money on plugs, coils and wires.

I will inspect the manifold tonight, I did not look at the pressure, But I know I had issues with Oil pressure reading low / occasionally dropping to low 20s when letting off the gas. I was told it was an oil filter issue and I changed the filter, Hasn't happened since. That was 2 oil changes ago.

2005 Chevy Silverado 1500 5.3 - 208k miles I was unhooking my boat at the boat launch (not on the incline yet) so I left my truck idling. As I was unhooking, It started ticking. Similar to this video https://www.youtube.com/watch?v=7ZnUiM6rsEE I shut it off, checked oil and all that. Started it back up and it resumed the noise. I was down a mile long 2 track and didn't want to get stuck there so I decided to drive out. Once I started driving the noise went away. Drove home fine, It has been 4 days and the noise hasn't returned. I called a shop, without looking at it he said it was a lifter and quoted me 10 hours plus parts. / My brother swears its a fuel or oil pump related issue if it goes away. I would like to confirm the issue, Where should I start? My oil pressure is around 35 at idle and 40ish while driving. After inspecting spark plug wires, I found 1 where the rubber had a big tear in it and basically disintegrated when I grabbed it. So not sure if this could cause anything. Oil & filter were changed about 500-1000 miles ago.
