Isuzu Rodeo
Report: Valve Train Noise Due to Varnish Build up
Isuzu Rodeo Problem
Model Years Affected: 1993, 1994, 1995, 1996, 1997
Engine Affected: 3.2L V6
Average Mileage: 137,000 mi (114,000 mi - 180,000 mi)
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.
