my oil smells like gas....do these engines normally have this trait??? also when i rev and let off it pops through exhaust sometimes.....what would cause this??? engine still has loads of power and accelerates quite nicely

 

The oil smell can be common. Check the function of the PCV system.

If the car is popping, then it may be running a bit rich which can also explain the oil smell. Find out when the last full tuneup was and if it has been a while, perform one.

Is the car stock? If parts of the emissions system have been removed or bypassed the popping will be the result.

 

car isnt completely stock......centerforce clutch...racing beat polished dual stainless steel exhaust.....koni shocks,eibach springs, apc air filter on stock piping, fresh plugs,ngk wires, so i am still clueless on it

 

You are getting the popping due to the exhaust.

 

if the oil isnt fresh over time it will break down and start smelling like gas. remember where gas comes from..... oil

 

i am aware of the oil and gas coming from same crude.....lol...thank you all for your replies....aaron..... my exhaust alone will make the car pop as it does??? if you have time can you explain why??? also....are the tanks in the 7's baffled??? cuz if i corner aggressively with 1/4 tanbk or under it cuts out....if i have baffles would one be failing?

 

I really dont understand alot about the rx7 yet.... I know i love my car and want to know more.......

 

I am assuming the exhaust has eliminated the cats. Without them, afterburn will be much more noticeable. Especially if the air pump is removed.

All the RX-7 tanks are baffled but if yours is sucking air under hard cornering, yours may have come loose.
