Big End Oil Clearance & Crank Endplay - Colt Turbo 4G15 - Updated Build Measurements
Got a chance to play with the block again.
With a new magnetic stand i got i was able to check the crankshaft endplay. It was within spec.
I also cleaned the bored about 5 times as i wasn't too happy with them.
These are all the current build measurements. I had to update them due to the crank getting a regrind.
Most of the time was spent on stretching rod bolts and testing oil clearance on the big end.
How to Use the Stretch Gauge

I did plan to install the pistons and rings but my ring compressor was a bit gay.
It would turn the rings as I compressed them.
