Lifter tick help will mmo or motor flush help?

Trey Hardy · Sep 8, 2022

I put a screw driver on the valve cover and put my ear to the end of it and the passenger side sounded fine I believe its the 3rd lifter back on the driver side from what I heard I’m changing the oil and filter tonight before I leave in the morning she ain’t done it since the Italian tune up but that don’t mean it won’t come back tomorrow or the next day might pull the valve covers off when I get home and check things out a lil more wish Me luck

Yeah that's #7 cylinder that's the devil mine is dealing with too. I have to switch that spark plug out every few years because of the oil fouling on that cylinder.

I haven’t had that issue yet I changed the oil a weight higher and threw a quart of mmo in the Tahoe I’m 3 hr in the drive almost home been running 75-80 the entire time since I left nags head so far no lifter tap I’ll report back in a day or two once I drive it around home.

I was a little wary of putting the additive in that motor with the mileage and the sludged up oil pump screen. Had a bad experience with that years ago, broke loose a bunch of the built up sludge and really screwed up the lifters in that old motor. I'd guess you're home now?

Yea haven’t done much driving today just moving around the yard to cut grass and to help hold the rear end straight while I changed blocks and u bolts out in my Silverado. I ran her hard right before I got home got a lil over 100 before coming off the stretch she’s been as quiet as a church mouse today

Drove it most the week while I was home and just got done driving it another 3.5 hr to work this morning so far so good she’s still throwing a vacuum leak from time to time I’m going to put the smoke machine on when I get home and try to sort that out next week

@Trey Hardy Prepare for if you gotta do the job but make sure to enjoy it! Don't want to live in fear of the motor going at any moment, that's not a way to enjoy life lol.

Oh yea man I know my buddy has a 6.0 out a nnbs I’m planning on getting and doing a top end in it. It was definitely nerve racking because 90% of the time she runs just as smooth and quiet but when it was tapping and me 4 hours away from home weren’t a good feeling and me being me I said I’ll put it to the bottom and it’ll either shut up or blow up one of the two luckily it shut up for me and has been good ever since I switched to the thicker weight oil and put the mmo in it.
I might rebuild the 5.3 for a obs project later on but right now id rather not take the Risk of putting 1000-2000$ in the top end for the bottom end to give out down the road but every Chevy my family owns has 300-400,000 miles the lowest one is the in-laws corvette with 220k on the dash so who knows she might last another 100,000 miles or so if so I’ll be mighty happy

What oil did you go with? I'm going to be switching to 10W30 on the next change.
