2.7 Engine Question

[Scoobz]

On this here pic of my ar5e end, laid bare for you to see my inner workings.



There is a pulley thingy on the bottom left of the engine, just below the black bar thing and to the left of the red cap jobby. Now i'm pretty sure that should be connected to something by a belt...

But it isn't.

Can anyone please:

• Tell me what it is

• Tell me if it should be connected

• Tell me if it is a job easily performed by me (with the technical know how of a chimp.)

• Tell me how to do it

• Or point me in the direction of some online help, tell me to sod off and stop asking stoopid questions.

Please

Thanks

Yours not attached,

Adam

Would that be the air pump ?
This was Porsche's way of improving emissions on some 70's and 80's 911's - Dilute them by pumping clean air into the exhaust manifolds !
I am happy to be corrected by those who know better, but I am not aware that this served any purpose other than to get round emmissions rules, hence it is often disconnected on older cars if the pump stops working or if owners want to liberate the couple of bhp it takes to drive the pump.

Adam,
It's the gobble nut which fits inversely into the sprogspar by way of nipplegimlet.

Piece of P155.

Sorry mate. I will go back under my stone.

Connect it to the inlet manifold instead - you've got a free Supercharger

If the pump to the right of the engine bay is the aircon compressor, then I would concur that the one on the left is the air compressor that indeed simply pumps air into the exhaust to dilute the gases to get over US emissions legislation. If so, then definitely don't connect it back up! However, if the car doesn't have aircon, then I can't be 100% sure which of the two pumps in the photo is the emissions one....

Water pump?

Thanks Ruby!

Also, thanks mike!
