I read some were about using wd40 to produce white smoke from your exhaust as a way of finding any gas leaks in the exhaust system .
Is it safe to do this with the 8 . I'm thinking of spraying it into the air intake after the MAF to find any .

 

where exactly are you trying to find leaks? if trying to find leaks in the intake system of the car, you would actually spray something safe like maf cleaner (or if old school a smoke machine or propane) on the vac lines to see if it causes a fluctuation in idle.

if you are trying to find a leak in the exhaust stream you would use the old school method of soap and water,

Spraying WD40 in your intake is going to do nothing for you except kill your idle for a moment or two.

 

I'm looking for leak in exhaust system.
Soap and water method where would you add that?

 

our exhaust system isn't very intricate so it shouldn't be too difficult to find. get a spray bottle and fill it with soap and water. Start the car, and while the exhaust is still cold, spray some of the solution onto wherever you think the leak is, if there is a leak it will bubble

 

or if it's hot, jack the car up, get a feather, go over the exhaust joints about 10cm away and you will see it the feather flutter when you go by the leak. I have used this technique, and like paimon said, the exhaust is not complicated (four places where it could leak I believe).

 

Chad has an extensive feather collection.

 

don't spray oil on the hot exhaust, its not a good idea! the exhaust is hot enough to set the oil on fire.

 

Uh, I think he meant burning it in the engine so that it would produce visible smoke that might leak out of a joint.

If he wants to do that he could just seafoam or atf the engine then start it up.

The 8's exhaust is pretty bulletproof. The only real place to have a leak (using stock components) is at the manifold-to-cat front connection, where the gasket does deteriorate with high mileage. The rear graphite gasket will probably never fail or leak and I can't see the engine block-to-manifold gasket ever going bad either.

 

 

You can also get someone to cover the tail pipe while you listen for the leak

 

sounds like a great way to ruin an expensive catalytic converter

 

They are really everywhere. In pillows, jackets, I have java finches and I slaughter my neighbours quails and chickens for her. If you don't have a feather get creative.

 

What if I just run the whole chicken down the exhaust system and pray no one videos it and puts it on a funny clip show on tv.

 

I kind of like my chicken burnt around the edges, don't need to hear about Chad tickling his exhaust pipe with a feather though ...

 

bwahaha!

 

Chad prefers to be called a "feather enthusiast"

 

Have heard of feathering the throttle but this is first time I've heard of feathering the exhaust !

 

If you don't feather your exhaust, then things come out too fast.

 

Science question what came first the chicken or the Rx8

 

bwahahahaha!

 

mmmmm chicken ...

screw rx8! i want my chicken platter!!!!!

 

I don't have anything to add, but I figured the one correct and useful response was worth repeating.

OK - everyone else can return to the chicken wars.
