Hi sorry for all the probably dumb questions. First a little history on my honda apparently it has previously been on on display in some antique shop in London for quite a few years, this is probably why most of the oil seals were missing (something I am finding out as I work through the various leaks. I am now at a stage to replace the oil pump. investigating the the oil pan some bolts are missing (although amazingly enough it doesn't leak). I read somewhere all the bolts are not the same length, could someone explain what length of bolt goes where, before I dismantle it as probably the bolts will be wrong, judging by experiences so far. Why they are missing I will have yet to find out LOL.
