Lifter noise on the right side
Always used 0W-30 Mobile 1. Ticking noise starter occasionally and by 100, 000 miles was getting to be annoying. Noticed oil pressure droops at slower rpm and seemed to coincide with ticking. Changed to 15W-40 full synthetic and this improved oil pressure and ticking noise.
i,m not sure, but i think it is the valve train tapping, can i adjust them ??
tapping noise have tried oil treatment no sucess
It was a gamble every day to see if the tick was there. But I had a broken woodruff key in my harmonic balancer and a chunck wad missing out of the balancer. Replaced it and the tick is forever gone.
Had ticking problem too...brother recommended sythentic oil and never hear it until it is due for oil change. love this vehicle!
I have a ticking noise that has been on both my current Rodeo and my old Rodeo (94). My mom said she too had the noise in her Rodeo (unknown year) and used Lucas oil treatment to fix it. I've yet to fix it on mine as I'm currently in the process of changing valve cover gaskets but I'll try to clean them before I put them back on and use Mobil 1 oil.
