Hi, there are two oil
fill points on our Yanmar
. One is on top of the rocker cover (where I would expect one to be) and there is another over the timing gears at the front of the injector pump
. There is a breather from the timing gear
cover to the air intake and we get some oil
collecting in the air intake housing. Can someone tell me if we have to add oil to the gear
housing or does the engine
oil circulate here. There is no dipstick or level indicator at the gear housing. Neither the owners manual or the service
manual make any mention of adding oil to the gear housing.
Thanks for any advice
that will straighten this out for us.
