1998 Toyota Avalon Sedan XL 4dr Sedan
Smokin' engine... literally
 I bought this Avalon having owned another 1st generation Avalon.Didn't figure I'd need to have a PPI, but I should have gotten one.Turns out the engine was a smoker.Despite replacing the valve seals and spark plugs, it continued to smoke.Quickly re-sold it.
