resealed o/s front and rear doors, was going to do the bit under the wipers (i forgot the name of it lol) but couldn't get the wipers off lmao, will do the n/s next week. i cleaned off what was left of the engine cover lining. i had a look at the EGR/Anti-Shutter Valve and it looks a dirty, can i use carbarettor cleaner on this?
