What he said,How soon we forget the original 4 banger, you think tickingJust a different thought.
1. These engines are overhead cams...kinda like overhead valve "Solid Liifters"......Old technology: no hydraulic cushion to supress the sound of mechanical parts banging against each other. ..Ticking??? There's NO problem with "Ticking" in high performance engines.
2. These new engines NOW have reverted to "Timing CHAINS"...like the old days...back 20+ years... before timing BELTS. Chains were reliable, no need to replace them.....ever. ..but they weren't as quiet as belts. It took awhile for Toyota to figure out that the price of "Quiet" maybe wasn't worth the hassel of "keeping an eye" on the belt, and replacing it every 60-90,000 miles. TacoGuy
