Hello. I'm in the U.S.

I'm looking at a 1991 Suzuki Alto Works RS-X with only 50,000 km's for $5,500 USD.

One of the problems is a small valve cover gasket leak. I've been reading that on the DOHC F6A engines, the timing belt has to come off in order to take off the valve covers.

I also don't know where to get parts. I'm pretty mechanically savvy... but with that being said am I an idiot for considering this?

Yes, the distributor also has to come off. It's an unnecessarily complicated design.
Parts are easy enough to get through Megazip, RHD and other resellers.
