What does Motorcycle breather tube do?
Purpose of a Crankcase Breather Tube As the pistons move, they compress the air trapped within the crankcase, creating pressure that escapes through a vent. Once transferred to the air box, any fumes and fuel vapor emitted from the crankcase is pulled back into the carburetor or fuel-injection system and recycled.
What kind of lubrication does a Ford 351W use?
Shown here is a 351W, but it is the same for Cleveland engines. MME Racing utilizes lifter bore sleeves to increase oil fl ow to mains by reducing oil fl ow to cam and lifters. This allows adequate oil fl ow to cam and lifters, improves oil control, and provides lifter stability.
Where does the oil go in a Ford 351 Cleveland Engine?
Oil is drawn to the pump from a front or midsump pan, then passed to a main horizontal oil galley across the front of the block where it leads to both cam bearings and main bearing journals, then up to the lifter galleys. The problem with this approach is oil starvation to main and rod bearing journals at high RPM.
What should spring pressure be on Ford 351?
Shaft to housing bore clearance should be .0015 to .0029 inch. If clearances are not with Ford specifications, reject the pump. Clean up the oil pressure relief valve bore with a ball hone, then, check for freedom of valve movement. Spring pressure should be 23.6 to 24.6 pounds at 1.37 inches. If you desire more pressure, add shims one at a time.

What should I do if my engine oil keeps blowing into the air filter?
Purchase an engine flush formula from your local parts store and follow the directions. In general you will pour the formula into the oil and run the engine for a period of time. Once the engine has been flushed drain the oil and fill it with fresh engine oil. Replace the filter and see if the problem persists.
When was the peak horsepower of the Ford 351W?
351W Performance Tricks. The Ford 351W or 351 Windsor is classic American muscle. Part of the 90 degree small block V-8 family of Ford engines, the 351 Windsor reached its peak stock horsepower in 1969 at 290. Though this small block is a platform capable of much greater performance, you can easily modify it to make more horsepower and torque.
