when I got my car it had a bunch of panels that attach to the engine sheet metal that I believe are part of the engine cover. are those needed if not are they worth anything or just recycle them?

Goughary

you need all but the bottom cover - you definately dont want the bottom cover on cuz it traps alot of heat...and you end up with burnt valves...dont ask how I know...lol...

mb911

Really I would not have thought the need at all once the bottom cover was removed What purpose does it have? noise insulation? it cant effect cooling as the sheet metal does that job . Just curious what your thoughts are

Are they the side covers or the bottoms?

The sides you want to put back on the car so the exhuast doesn't cook the engine.

The bottom cover has been long debated.

Yes, it traps heat in.
Yes, it was part of the Euro noise abatement regulations.
Yes, it is an aero device.

You might want to show us a picture of what you are refering to.

16,17, 14,18

I used there catalog cause this pictures came up right away looks like each panel is approx $300 so I guess I dont want to throw them out but want to know why I want them.

Makmov

You will want to put those bits back on the car.

Ok but the question remains why what really does it do? It cant effect cooling as I said sheet metal does that so What really does it do?

Makmov

I already said why, it's a insulation - reflective heat buffer between the the engine and the exhaust.

The sheet metal was mainly for keeping the engine compartment clean.

ah ok I can buy that they must have realized after the 3.2's that heat soak would be more of an issue. I will reinstall them thanks

The main purpose for 14 & 18 is to shield the plug wires from the secondary muffler on one side and the cat on the other side.

My car doesn't have the front shields 16 & 19. I do have 14 & 18 installed.

It appears the purpose of 16 & 19 is to shield the case/chain covers from primary muffler heat.

Anyone running without 16 & 19?
