Hey, I've got this horrible ticking noise in the engine that is very
inconsistant. It started w/ just doing it after 20minutes or more at a
sustained speed on the freeway when I got off the freeway, it would start
making the noise at around 2700rpm and as I reved down down. You can hear
it really good at Idle. I've tried all accessory belts, and they aren't

I've been using low weight (5w20) Mobil 1 for some time, since about
90K. It has 120K now. The engine used to tick mildly most of the time
but. Mobil1 has controlled the ticking except when I use the premium
It's either the timing belt tensioner or the famous HLA (Hydraulic Lash
Adjuster) issue thatpops up with this engine. You'll have to look back in
