Hello All
Well, engine assembly is moving along at a slow pace. Installed crank and new updated rear seal. Installed liners using new Payen steel Figure 8 gaskets with WellSeal on block, on Figure 8 gaskets, and on bottom flange of liners. Fit them, gave them a few good taps with my rubber mallet, and installed bolts with fat washers to hold liners in place while building the short block. Didn't torque these bolts to any criteria but did tighten them well, so the liners are not budging and are firmly seated in block.
Put a straight edge on liners and pushed my feeler gauge every which way to measure liner protrusion above deck. The 0.002" will usually not slide under the straight edge but the 0.0015 slipped in every location. The liners are new BPNW 87.5mm, in case anyone cares.
Bottom line. I'm pretty satisfied that this is close enough to 0.002", which is minimum protrusion. Would really (I mean really) hate to remove the crank and take back to shop to shave 0.002" off the deck to improve the liner protrusion above deck. I read in the "Restoring your TR3/4 Bible" that the steel washers don't compress so you want to be on the lower end of the range (0.002 to 0.006) for liner protrusion above deck.
Any thoughts or experiences on this? Trying to do this right and looking for someone to help me sleep better at night (hold the off color jokes...).
As always, thanks to the Forum for all the great advice and for keeping me occupied when work gets tedious!
