Re: Engine overhauling

["David Teitelbaum" <jtrealty@xxxx>]

I have not rebuilt the PRV engine yet so what I am giving you is out
of the DMC Workshop manual. You are basically correct with the
dimensions you have given. In the DMC manual it does not have any
specific cautions against using more than 1 seal (it just assumes that
1 will do it). The difference in protrusions between any two ajacent
liners should not exceed .04mm (.0016"). Differences must be "stepped
among the cylinders in a bank. (Don't go up-down-up). I would continue
to try Volvo dealers. Talk to the service manager and get him to help.
There might be a spacer ring that you can order to get you "into the
ballpark" so that you can finish up with a selective liner base seal
that will get you closer to the high end of the protrusion
specifacation or they may tell you it is perfectly OK to use more than
one seal. The use of more than one seal may allow more "crush" so you
may have to exceed the high end spec and instead of .23mm protrusion
.25-.26mm may be alright. The engine in a Delorean is very close to a
Volvo 760. The core (which is what you are doing now) is identical so
the assembly specs are the same. BTW you are supposed to use a "Thrust
Plate Bracket" on the liner and a dial indicator (clock gauge) to
actually measure the protusion accuratly . You are dealing with very
small measurements here so take your time and try to be as accurate as
you can be. You should be able to do this with a flat plate and feeler
gauges. The manual says to measure in 2 places being opposite each
other and use the larger one for measurement purposes. Eveb if you
reassemble with the protrusion .147mm the difference from that to
.23mm is VERY small.
