In reply to a message from Eric318 sent Thu 1 May 2014:
Certainly you should start with more disassembly and
cleaning of parts.
In addition to Peter’s list of questions, I’ll add a list of
the order in which I would spend your money.
complete gasket set
spark plugs, wires, distributor cap
piston rings (evaluate pistons for excessive wear on skirts,
replace if damaged on top)
connecting rod bearings (evaluate crankshaft for scoring and
timing chain tensioner pads
distributor driven gear
evaluate piston bores, use Flex-hone for light cleanup (or
rebore for oversize pistons)
timing chain sprockets
distributor shaft bushing
No doubt I’ve forgotten something.
You may read about timing chain stretch. Its not quite a
true way of expressing it, what happens is there are
something like 100 links and if each link pin is worn .0001’’
the whole chain will be worn .010’’, each pin .0002’’ is .020’’
on the chain, and so on.
So keep at it and this forum will help.–
