Trailblazer 325 puking oil all over interior of welder

[rjmack]

again... there is no oil pan on this motor, and the base of it appears to bolt directly to the fuel tank. the oil drain heater is interesting but again, it's definitely to big to fit into the engine, and given the fact there is only 2 liters of oil in the crankcase I think it's important to leave the...

maybe I didn't explain the situation clearly enough. the area where the gasket has blown, allowing pressurized oil into the crankcase vent circuit, appears to be cast into the intake manifold. that is the same area where the crankcase vents comes up into a chamber with a foam element in it. that chamber...

the blue line showing the machined flange underneath isn't in exactly the right place but its hard to put a line in the right place using my road laptop. this picture was taken before I removed the gasket to get the emulsion soaked foam vent element out. of note is the fact that while much of the gasket...

Well guys, the news is not good. I am pretty sure this machine (trailblazer 325 efi excel) suffers from a catastrophic design flaw in the kohler engine. unfortunately, the miller reps are not cooperating at all. one has blocked my emails ([email protected]) and the other is refusing to even...

whether or not there is fuel leaking into the crankcase, the crankcase is not venting in freezing conditions. it works fine in the one heated building on site but as soon as it's out in the weather for a few hours it freezes up. I think/hope I found the problem. there is a plastic element filter in...

btw, i'm in the northwest territories, two flights from yellowknife to get into camp. they trucked my rig up on the ice road. this is the definition of the middle of nowhere, and the new fuel injected kohler engine is the only one on site broken down.

thanks, i'm hoping to have the site mechanic look at it tomorrow. it just happened to blow a gusher right when i was checking it today. there is obviously a huge amount of crankcase pressure building up and zero ventilation.

this machine is fuel injected but i will look for any openings...

Miller 325, approx 150 hours, will not stop popping the dipstick and drenching everything with oil. its probably only a matter of time until we get ignition.

started happening immediately after being taken into very cold (-40*) environment.

cant find anything in the literature...
