depends on the vehicle type man

if its a honda probably like 50 cents heh

nah but on the real timing chain/ timing belt... turbo or NA... lotsa shit involved but yeah

if its like a VW or a 300zx or something its gonna be fuckin expensive... ($1k labor +)

if its like a civic or a corolla its gonna be cheap (300-600$ labor)

then you got parts, the gasket set = pretty cheap, but if ur head is warped then machine work = like 80 bux, if ur head is cracked you're SOL, slap another 300-500 (honda/corolla) onto the total LOL
