subieApprentice Posted January 8, 2010 Share Posted January 8, 2010 what could cause oil to get in the carb? One of my co-workers/boss said it was a valve i just forgot which, anyone have any answers? Quote Link to comment Share on other sites More sharing options...
Jonv23 Posted January 8, 2010 Share Posted January 8, 2010 Subaru 360's don't have valves. They are 2 stroke! Also, since they are 2 stroke, they don't have oil in the crankcase either. Are you sure it's oil? Is the line from the oil pump hooked to the crankcase or the carb? Was it running before and just started doing this? More info is needed.

subieApprentice Posted January 8, 2010 Author Share Posted January 8, 2010 sorry I didn't mean valves in that sense, but like an oil check valve? Quote Link to comment Share on other sites More sharing options...
Jonv23 Posted January 8, 2010 Share Posted January 8, 2010 no oil check valve on a 360. Oil is pumped into the main bearing and slung up onto pistons, it all burns off eventually. are you a 360 club member? Quote Link to comment Share on other sites More sharing options...
subaru360 Posted January 8, 2010 Share Posted January 8, 2010 There is an oil check valve on the 360. It's at the inlet to the oil pump. They leak. It's just a ball and spring. You can take it apart, clean it and stretch the spring a little. It might help. I haven't had much luck with mine, even cleaning and stretching it. When the car sits for a long time, a lot of oil leaks past the check valve and it smokes like an active volcano for about 10 mins. If I drive it everyday it's not so bad.

subieApprentice Posted January 10, 2010 Author Share Posted January 10, 2010 It was acutally an oil/fuel mixture valve, is any one familiar with this? Quote Link to comment Share on other sites More sharing options...
subaru360 Posted January 10, 2010 Share Posted January 10, 2010 The oil pump has a variable rate, it's controlled by a cable that runs to the carb. It pumps less oil at idle and more at wot. Quote Link to comment Share on other sites More sharing options...
subieApprentice Posted January 11, 2010 Author Share Posted January 11, 2010 oh thats cool, so possibly its just stuck open? Quote Link to comment Share on other sites More sharing options...
subieApprentice Posted January 12, 2010 Author Share Posted January 12, 2010 do you have any diagrams of this valve, like location and what its connected to Quote Link to comment Share on other sites More sharing options...
subaru360 Posted January 12, 2010 Share Posted January 12, 2010 It's part of the oil pump. There's a lever coming off the side of the pump with a cable attached to it. The cable can get stuck wide open if it's not adjusted right. If you are working on a 360 that's been sitting around for a long time, it is going to smoke bad, not much you can do about it. It will keep smoking until you get it out on the road and drive it hard, as in wot, for a few days to burn all the old oil out of the engine and exhaust system.
