This is a discussion on oil leak within the Grizzly Engine & Transmission forums, part of the Grizzly Forums category; oil is pouring out of the cylinder head next to the header pipe ...is this more likely to be the head gasket or valve seals? ...
its a 2009 grizzly 350 irs
it runs great and has plenty of power but oil is coming out fast where the exhaust pipe comes out of the head. makes no senseto me. im taking the head off but the front two head bolts won't clear the frame to pull them all the way out. do i have to tilt the engine forward for there to be enough room to get the head bolts out?
thanks for your replies

Reason: more info
It should be above the spark plug towards the top of the head.im not 100%sure the 350has them but most air cooled yamahas do,get some degreaser and clean the area good and thren run it to locate the leak.if its (pouring)out you should be able to locate it.
got the head off...the leak is at the head gasket so new gasket ordered. what happened is a previous owner broke one of the exhaust studs off. instead of replacing the stud he attempted to weld the exhaust pipe flang to the boken stud...total mickey mouse job. The extreme heat from welding there created the leak with the head gasket.
now im wondering where the plug is to see the mark to set TDC on the flywheel for setting the timing when i put this thing back together. Is it under the rope pull start cover?
