Shawn Szentmiklosy: Question: my 2005 chevy suburban 5.3 makes same exact noise. Fist start sometimes quiet then gets louder. Then oil pressure drops sometimes. After it warms up sound disappears oil pressure stays up. stopping to get gas or what not you hear it again then disappears. So what is it same thing? Oil sensor where is that located?
patchreefs: Brian didn't realize it was you talking forget the oil change idea.
patchreefs: Could be caused by dirty oil. Do you change every 3000 miles
Orlando Alcantara: its the same problem i have on my 02 chevy avalanche ..5.3.....
David James: I use Marvel Mystery Oil in my crankcase. It will prevent this crud from forming in the first place. If you add it to your oil now, it will keep the passages clean. If you put 8oz for 20 gallons of gas, it will keep your fuel pump, and injectors, etc. lubricated, as well as prevent carbon from forming on your pistons and rings. And it will help keep your cat converter clean.
kourtney littlefield: This is probably the best video I've found by far... My 08 5.3 ticks so hard. I'm determined to tackle it this weekend and see if what you did will work for mine also. Thank you
Adam Brock: Great video but wanted to share my experience. My 2005 Tahoe 5.3L had a ticking valve. The first or second valve on the drivers side. Would come and go but very irritating. I replace the valve cover on that side and tried the Chemtool spray to no avail. The problem is the O-ring on the oil pickup tube in the oil pan. I dropped the oil pan and found the o-ring was cracked which was causing lower oil pressure and the oil not to travel to the front lifters. I replaced it and no more ticking.
matthew stumpf: i have a 2006 z71 5.3 vortec. my engine made a little noise like that and consumed lots of oil. I did one oil change with Castrol Syntec 0-40w European formula and the engine is quiet as new and no longer consumes oil!
fourmileroad1: Thanks for this video. Will try this before I spend the $2k on a replacement motor that the shop recommended.
Ernest Miller: My Tahoe started doing the same thing at about 160k on start up if it wasn't driven every day. I started using synthetic oil and the problem was solved. Now has 178k.
matt wells: my 2001 Ford Explorer Sport was eating the motor oil up and we always had to add oil it was the Oil Pump
Hughie Boss: Did the oil pressure change at all after your fix? My guess it stayed about the same.
Gisamy Guillen: I have a 2005 Chevy Equinox and the noise that it does sounds similar to this one but it's not all the time that you could hear it, I think it's the oil pump cause my engine isn't receiving any oil and I barely changed the oil in my car but I don't know what it is honestly , any thoughts?
John E: I have the identical ticking on my 2002 Silverado. Think it was caused by maybe the high mileage oil I started using or putting in the wrong weight oil on the next oil change. I tried an engine flush with the top brand, didn't have any effect. The oil pressure is at 50 , it's usually around 45. Switching to a Bosch oil filter, instead of a Fram might be the cause for that or something is plugged up. Guess I'll try pulling the valve covers and using some B-12 on the first two push rods(?) Just how safe is it to drive it with this ticking going on?
randy savage: Exact thing just happened to my 08 5.3. Sounds very identical. Gonna pull the left side valve cover and possibly head asap. Hopefully this solves it.
Jou Nowho: Best "episode" yet hahah ! Keep them coming you intelligent psycho
Teddyvision: are you Canadian?
Teddyvision: you can't pull the lifter with a magnet?
Emmanuel Melendez: your great man, keep up the good work!
Ben Montgomery: Absolutely the best explanation I have found on YouTube! I have been stressing over this problem with a new truck I bought thinking I made a huge mistake. Thanks Brian for this very helpful video!!!
