Careful ... that last phrase constitutes fighting words 'round these parts ... >
Think about this, folks. Most
cars have hydraulic lifters. Thing is, most cars also have their engines in front of you by at least four feet, behind heavily insulated firewalls and dashboards and covered with all manner of clatter-deflecting plastic and sound-masking audio speakers.
Our 718s are not most cars:
- The engine starts about a foot behind your head
- The engine compartment is not heavily insulated
- The engine has absolutely zero cosmetic/insulatory bits bolted directly to it
- The boxer design promotes
engine noise when cold because the crankshaft and cylinders are at the same level and almost all crankshaft-driven bits are above both -- because of this, oil basically reaches the crankshaft train last
- That crankshaft train is closer to your ears than the clutch, the cylinders, the crankshaft, and the exhaust manifold
- The four-cylinder configuration masks drivetrain clatter less than a six-cylinder configuration (this has to do with the aural effect of firing order)
- Etc., etc., etc.
Almost all of the cars I've owned have exhibited varying degrees of tap-type engine noise, particularly when cold. Thing is, it's only really noticeable when the hood was up on most of them. Essentially, our 718s are operating with the 'hood' partially up all the time
because of the above points.
My very first car was a 1974 VW Beetle, which, as another poster has mentioned, had tappet noise for days
. So do any and all air-cooled 911s. I guess that in my case, the noise is sentimental ... but I'm also attuned to it, and because of that I note it in every car I drive.
