A couple of the intake tubes are worse than others, and I'm positive it's leaking a bit around them. I've checked literally every nut and bolt on the engine for tightness. Snugged them all up. I may have to cheat a little bit with some engine sealant around the nuts and intake tubes - I'm hoping getting some more run time on it seats them a bit better but I'm not so sure. Air leaks would probably cause a tuning disaster I'm sure. If it continues to make a mess, this engine may go as backup for spare parts then. The rockers definitely stay lubed on their own though with this one
