Engine fired right up, but when it gets to max temp 185-190, it starts blowing blue smoke from the exhaust. Any thoughts on what would cause this? There also appears to be oil dripping at the header collector flange. When I replaced the headers, I installed a fresh set of plugs and noticed that they had oil on them. I checked the PCV valve and it's good. I'm planning to do a compression check on all of the cylinders next but thought I'd check here the mean time.
