Changed the FPR a week back to a bypass-style and the car was running great! Drove it to SF, to work, and today drove it down to Scotts Valley for the Canepa Cars & Coffee event. C&C was fun, lots of cool machinery and a very eclectic mix of cars. Went with a buddy, I believe spitz17 on here. Took this photo at lunch, didn't even think to take one at the event...
Didn't take a lot of pictures but this was one of my favorites:
Took the long way around to get home, up CA 84 and into the mountains. I'd been doing so many valve adjustments and careful test drives that it was liberating to finally let it rip, holding revs at 5-6k with glorious noises coming from the sidedrafts. Got to the top and was making my way down when I saw a big plume of smoke in my rear view mirror. Fearing the worst, I grabbed my fire extinguisher and got ready to pull over. Checked vital signs: coolant, oil pressure, amps, all okay. The tranny tunnel was cool and the smoke seemed to be coming from the exhaust.
I kept driving and performed some experiments. The biggest plume of smoke always came after decel. I haven't popped the valve cover yet but I'm fairly confident that the valve stems seals took a crap. My exhaust system was covered in oil after limping it home. This might also explain the slight smoke/oil burning I've been getting as well as the rev hang that I started to get today on the way to Canepa. I don't know if the seals dried out or failed catastrophically but we'll see when I remove the valve cover. I'd like to do a compression check as well since the radiator likes to spit out coolant.
Hope to have this pin-pointed quickly! Anyone have a Rebello motor sitting around...?
