  |
|
| Have an 05 350 two dinger banshee that i purchased 2 weeks ago, went to go for a spinn today and found what looks like gearbox oil runing out of a crank case breather tube all over RH expansion chamber. Would i be right in thinking the crank seal is leaking and pressurising the gearbox ??? |

Had the same thing with mine a while back, was flogging it hard an was slipping the clutch lots. Changed the gaerbox oil and stoped it spewing out, Another thing to do is build a leakdown tested, comes in handy for checking crank seals, heres a link.

Also made my exhaust plugs different and used a liquid filled low pressure gauge
