i have a 92 civic si with a 95 gsr swap...then engine is totally rebuilt for boost...when i drive it for a long period of time and take off the oil cap on the valve cover quite a bit of smoke comes out...i was wondering if anyone has had this happen to them...and also what the running temperature should be.

 

I've noticed a little bit of smoke every now and then when I open a hot oil cap on my B18CR, but your coolant temps should average about 180, but alot of people run from 210 to 170.

 

well what if im running at 210 on the highway and when i slow down it goes up to 250 with a full radiator waht would be causing me to overheat...i have a performance radiator too
