Why the plastic cover over the bottom of engine?

CBRich · 07-18-2009, 01:05 PM

I'm waiting for a used Enzo in the 20K price range. What a beautiful car.

And just adding a ditto on the aero effect to prevent lift.

You have no idea what a hard oil change is until you check out the new Civic Si (2006+). Well, I wouldn't say "hard" I guess. It was just more troublesome than it should have been.

I'm a die hard Z car fan but the 1984-1987 300ZX was... well it was like the Mustang II - fugly.... the '88-89 at least they put the European bumpers on so the car didn't look like a TR-7 wedge....

I had a plastic cover under mine... removed it. I haven't noticed a difference. At least the one on an Evo has separate pieces so you can get to various places (like there's a removable piece under the oil filter for that purpose).

Ditto on the aero effect, but what some people fail to remember is that the cover is commonly called a "splash guard." Not only will it improve the aerodynamics of the car, it will also prevent unwanted debri or pests from entering the engine bay (if conceived correctly).

I do have to agree, however, that Nissan went into overkill mode with the 16 bolts and 3 clips (which will probably be broken by most after the first oil change). It's a pain.

Yeah, What the heck. Those engineers probably didn't know what they were doing anyway. Pull off the spoiler and the aero flaps in front of the wheels too..

He'll notice a difference when that flimsy-looking oil pan is shot or a piece of debri blows a hole through the filter, or knocks it off entirely.

At least the Z uses bolts. Evos got a shitload of those crappy plastic screw clips that either don't unscrew or break.

Aero flaps?

The spoiler makes a HUGE difference. I've driven Evos with and without, and it's VERY noticeable.

Anyways, on an Evo, it's called a splash guard. Doesn't do too much IMO since it never gets dirty under there.

it started out as drip pan, so you would not get oil drips on your driveway. (older cars)

then it evolved into a shield to direct more air through the radiator, past the engine and through the transmission tunnel to cool the transmission. the trays got longer and longer.

then it turned into an aerodynamic aid.
