I did a compression test today, probably found out the roots of the hard cold start...

#1 100PSI
#2 290PSI
#3 200PSI
#4 200PSI

Then I plugged an air regulator into the compression test injector adapter to try to see where the pressure was leaking to and discovered that the only air leakage was coming through the crank case..

Was curious if the turbocharged engines had the same stroke and bore, for a possible conversion to the turbo's pistons? Can these 4 cylinder engines be converted to use turbos reliably?

also on a drive back from seattle on thursday noticed that while on I5 any time id use the engine to slow the vehicle it would smoke.. thought at the time it was probably the valve seals, but I suppose its probably just the sloppy rings on the pistons..
