Lifter tick / Diesel-sounding idle

Slippercream · February 27th, 2007, 02:44 AM

Are you detonating? Feel like you've got circus fleas in your cylinder head?

Go figure. You've got MIVEC. In a nutshell, no you don't have to fill your car up with diesel next time - and no you don't have to put jet fuel in it either. MIVEC (or in layman's terms, variable valve timing) involves a secondary track/set of lobes in the camshaft used in engaging that extra set of valve lifters (your beloved MIVEC lifters). These MIVEC lifters, when not engaged, simply "flop around" with the camshaft unless engaged - during which you get that mini-turbo, ass-to-seat... ish... feeling, moreso if you have a V6 than an i4.

Now, as carried over from the 4G section of Club3G, some have said that lifter adjustment both reduces the ticking noise in the cylinder head and increases power. I'll have to say (and with a certain ManyBrews' blessing hopefully) that adjustment, unless absolutely necessary, is really unnecessary. If anything, overadjustment (i.e. decreasing valve clearance) will likely cause the engine to overheat quicker than if left with the regular gap.

So much for "layman's" explanations, huh? Time to learn more about engines then - www.howstuffworks.com

Oh... just in case I was too harsh, let me also just add that in the event that your car starts sounding like a diesel TRUCK...

...

... check your oil. It's probably below 1/4
