what about all the black crap around the bottom of the valves? where plugs go in should i use something to clean all this? and will rubbing these down not leave bits of fine metal lying around i dont exactly have an air blow gun or anything?
clean off with petrol , yer can clean the valve stems with the cutting paste, or wire wool , do it away from the heads, if yer want to blow it off , use the trye inflator at tesco fer 20P
