Casyk

Okay so im new to this page but i have a 2004 mazda rx8 that i let my buddy start driving and he ran it really low on oil and ended up running it out of gas. I have looked for other forums but nobody really had a clear answer or the same exact problem that i could find. So we had it towed home,put oil in and gas and had to go through the deflood process to get it started once we got it started smoke just coninues to keep rolling and found a large oil leak from the front seal. I just replaced the plugs car has 117,000 miles all stock and never had a problem with it. Also i have not replaced coils or wires yet just ordered them. Please help
