Isuzu Rodeo Ticking Type Noise from Engine Valve Train

(16 reports)

A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.

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. -

Had ticking problem 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. -
i,m not sure, but i think it is the valve train tapping, can i adjust them ?? -
