Got the degreaser out and gave the engine bay a bit of a clean, I've replaced the heater fan in the cab as the old one was warped and catching, also I thought the roof was rattling around the tailgate so checked it, found the two rear bolts were loose and no middle bolts or front bolts around the base where it meets the body of the car. All bolts tightened or added so now not rattling there. Unfortunately the chap who helped do the brake master cylinder bent the metal mud guard and its actually ripped the inner wing which now has two holes where the bolts should be to hold it on, sothe mud guard is now off, and to be fair it neede replacing, two big holes in it.
