Over the past month or so my car has developed some pretty nasty pinging. I've run supreme gasoline ever since I've owned it (May 1st, 2000), and I run Mobil 1 Synthetic 15w-50. I've cleaned the contact points on the cap and rotor, etc. I checked my spark plugs and, this is what sucks, there was oil on all four of them. I'm not an experienced wrench, but I think that means bad piston rings right?
So it's time for a rebuild I think. So how much cash are we talking here? How much for a stock rebuild, or if I wanted to upgrade my cam and such, how much would it be? I've been told I could just get a lower mileage engine and replace it....but that seems like I'd just be putting the rebuild off...sort of like a band-aid fix. Though it would be cheaper I assume.
