I've got to get with the picture posting stuff instead of describing stuff. Tecumseh is also a good donor. They have a seam halfway along. Pass side has two 3/4" tubes. One is a low straight tube, when
oil accumulates it drops it back into the pan via a yellowed clear hose. The other one halfway up has an elbow dropping a draft tube down into the tunnel and the road. This is a great way to
oil your rear tires and stop them squeaking too. Drivers side has a 3/4" elbow halfway up that hooks via tube to your plate on the rear of the intake manifold. This is your breather to supply the puke tank with yucky contaminated
oil sludge. The other tube is a 3/8 that has a hose to your tranny top cover. Some trans top covers I have used elbow barbs, others I have just welded a tube into. They need to be close to the trans to duck under the tunnel.
