almost down to the last remnants of the 83 motor to come part
moving all the parts to the 90 motor that I was lucky enough to acquire from Rickg , as its the best option I have at the moment
there are some differences in the pistons rings etc over the production years on this 90 motor
but have balanced up the weights of rods and pistons to each other , to the best of my ability with tools to hand and hope that it may make a smoother running engine
ring gaps were similar to gertys (at 200,000 k round about) at 20 odd thou gap, so that's not too bad , the 83 engine was 30 thou gap , so some advantage to be realized ,. I hope .
assembly soon to occur as new parts arrive for the output shaft (small end bearing and running bush ) as it seems that with wear in that bush and bearing seems quite consistent with the acquired mileage across a few I have seen .
block and pistons ready to go in , as soon as I can get the right ring compressor
have had issues fitting the piston rings back into the block with an oversized ring compressor that is hard to control as compression is approached , ( the pinned second compression ring , fighting the snap action of the compressor that I had as it approached full tighten , snapping two rings so far ...bugga )
big end slippers have been replaced for new (with some white metal actually on them , instead of base metal appearance ) and journal slipper selected from the best I have across several motor parts here , and reusing the 90 crank as it appears to have the best surface , close to original as I can see .
also have resolved what appears to be a sticky lifter , on dismantling , found a score vertically in the bore of output 2 , restricting rotation etc , now linished and back to smooth operation as far as I can see.
but hopeful to get a right sized compressor tool soon and finish that part .and let me finish off buttoning up the motor
head gasket and bearing parts on the way...slowly it seems ...
