More trouble. Was driving the F.5 donor engine yesterday. About 20 mins in when it would't idle. No dig deal, I figured something simple was amiss, maybe some sh!t was passing through the carb or something. Anyway, I pulled into a service station, adjusted the timing back a whisker and hit the road. Seemed to be good til it happened again a few minutes later. Pulled over and found this:
Ouch! The side cover was weeping [running] oil too. The water is to displace the oil from the hot manifold.
- Pulled the rocker cover and cranked the motor - oil seeped out the rocker arm spines [including arm #1 - it shot out!] so that was all good.
- Oil pressure was good [42psi at idle warm, 60psi at idle cold].
- Fuel was clean
- New points [gapped at .20 thou]; plugs; leads; coil
- Recently timed from TDC; idled; mixtured
- Rocker cover vent pipe not blocked
- Good cooling system
Any thoughts on all this? I googled for a while by the roadside and I'd say this is blow-by [landcrusher909 also suggested this]. It's at the shop ready for electrical work tomorrow so I have a window for mechanical work whilst it's there. Ideas?
