If the head bolts came out easily and look okay (no evidence of corrosion or
pitting), they should
be okay to reuse. If not, I imagine most of the vendors have them (see
http://www.gordon-glasgow.org/gpagebld.asp?Type=Link&Cat=Vendor).
Main bearing cap bolts are usually fine, too, but if anyone feels they are
suspect, the vendors may
have them. I couldn't find a part number in the roadster parts manual for the
bolts. You can also
get them from a Nissan forklift dealer (yes, I said "forklift"), part number
12293-P0500. Tell them
it's for an H20 engine if they ask.
The critical ones are the rod bolts. I feel these should be replaced.
Unfortunately Nissan doesn't
supply them any more. ARP did a special batch of roadster rod bolts one time. I
think Dean at
Fairlady has most of those but Stan Chernoff may have some, too. If you don't
mind "customizing",
I've been told that 396 Chevy rod bolts can be made to fit by turning down the
knurling on the shank
of the bolt. I'd let a machine shop do that, myself.
Any of the vendors can supply you with timing gears and chains. If I had to
choose between replacing
timing gears or timing chains, I'd do the chains. If the gears are really shot,
odds are extremely
good that the chains are, too. That's not the cheap answer, but a blown engine
is even more
expensive.
