i just recently got my motor back....
gsr motor , new pistons , rings, main and rod bearings, oil pump ... 81.5mm
some head work also

i have put 65 miles on the motor so far... shifting at 4k or under so far and have not done any WOT. i did keep it in 3rd gear last night and let it hit vtec once and then shifted, then back to shifting at 4k or under.

i took out the #4 spark plug today to take a look at it. i then looked down the spark plug hole and noticed some oil on the piston. so i took out the other 3 spark plugs and looked at the pistons.. they were a little black...

any reason why the #4 piston has some oil on it?

 

what do your spark plugs look like?

 

kinda black, dry not wet .. seems to be a little rich.. getting an adj fpr tomorrow
