Fred I doubt with it been a ex rac van that the timing will be to advanced,
Most vans from these establishments just like old bt vans are sold because of their milege i suggest to you that transits from companies like these just get thrashed as the drivers dont own them, I would just puit it down to excessive milege and wear and tear, On the other hand it maybe just could with a oil and filter change!
