I am in the middle of tearing down my engine for a rebuild (it has been
sitting since 1992 completely open with the head off) In so doing I decided
to figure my displacement and compression (hence my earlier e-mail) when I
figured up the displacement I came up with 1684cc is this right or have I
been sniffing a little bit of exhaust fumes. Is it possible for someone
before me to have increased the displacement that much? I used brake fluid
to measure the displacement (it was available OK) measured by using 60cc
irrigation syringes (benefits of working in a hospital) 100% accurate,
probably not, but I don't see how I could be off by 200cc. I was under the
impression that the engine had never been touched, with an actual 56K miles
on the engine (I did discover an odd screw on the oil pan, so I know it has
been off before) How can I tell if the engine has been rebuilt before? and
How can I tell how much as been removed from the head and engine deck
surface. The engine has flat pistons that are at 0 deck height at TDC, is
this normal?
The crank appears in outstanding condition, no scoring, thrust bearings were
good with almost no runnout. The cam looked ok, but it did have dark spots
(half moon shaped on the edges) is this scoring? and do I need to replace
it. If I am taking the engine to be hot tanked do I need to clean it at all
or let the machine shop deal with it? And what is the list of "must do's"
since I am having the block machined. what else should I have done.
How bad is it to reuse old valve springs, the machine shop said they were
fine, but they didn't test or measure them.
Thanks, alot as always
