Thanks guys! Summer's here, and with outside temps around 20-25*C the SEL has been running a little hot. I'm flushing my coolant this afternoon. I have a small overheating issue, but it's not boiling over. Idle gets really rough around 90*c, I'm sonn going to swap out the WUR to see if that changes. I'm also going to look at the timing today.. Good day for it
