I'm preparing to perform the arduous removal of the head gasket, intake/exhaust gaskets, etc. because I know I'm leaking coolant. I've avoided driving the car for several months and the rainy season is almost over and I don't have a garage, so in three weeks I'll have my window of opportunity. I've read through the Chilton's and a pdf version of the European 1991 Accord (from a friend). I plan on buying genuine Honda parts from Majestic Honda, as they seem the most affordable for Honda-branded parts. Anyway, what else should I consider, as a shadetree mechanic (I'm confidant I can do this)? Since I'll have to pull the head off and get it machined/trued should I consider replacing all the valves? What does replacing the 16 valves entail in terms of all the parts (e.g. valve stems, valve stem seals, valve springs, getting the valve guides "knurled"? Would it be more cost effective to get a local shop to rebuild the head? Any special tools that I might need to invest in (valve spring compressor, etc.?) Thanks for any advice.
