Pops Bangs And Running V Hot

[speedtripledan]

Found out why my car has been running v hot slightly rough and popping / banging out of the exhaust. Where the silencer clamps to the manifold was loose really loose!

 

Tightend it up and what a difference ! smoother faster no pops or bangs and a lot cooler over all

 

Must have been running lean as a result of the exhaust leak

Hi Dan don't you remember the long running debate [?] on this subject some time ago ? ,a loose joint will give pops and bang because of a tiny amount of unburnt fuel and fresh air being sucked into the system will ignite mainly on the overrun /closed throttle ,by sealing the joint there is nsuficient oxy in the system for it to burn /ignite , even the Cosworth DFV F1 engine did it when exhaust systems were not as efficient in the 70's as now regards,mick [mower man] waiting for incoming.

I certainly do remember ye said debate It was the increase in engine temps that got me with this one...

Just havin an engine would be nice

So let me get this right,

It's the added oxygen entering the hot manifold that makes the pops and bangs?

No its your ears/ brain that convert the difference in air pressure created by the sound waves into pops and bangs.

I always thought it was the pixies that live in the exhaust that make that noise ????
