all right got a question for all. the motor in the submarine is starting to blow oil more profusly, profusilly profoosilly anyway the blow by is really bad now. but i have a spare motor with very low mileage , (that i might as well put in while the original is still rebuildable ) ,but it has sat for about 2 years. any suggestions on prep work before installing like pull the distributor and prime the oil, replace the rear main seal while its out the jeep. any help like that, ive rebuilt alot of chevy and ford motors but didnt know if jeeps have a tweaker spot
