The valves on a Ford 300 straight six are not adjustable. If they are noisy you have worn valve train parts.

How do you adjust tappets?

Hey Dave==This does apply to the 305 since it is a chev engine. A 301 is a PONT engine and they have stops for the adjusting nuts. The 350 and 305 have hydraulic lifters and adjust as follows: Pull the coil wire so the engine won' start and bump the engine until the valves on #1 cylinder are both closed. Now turn the engine so the timing mark is on TDC. Adjust the following valves: INT 1-2-5-7 EX 1-3-4-8 Then turn the engine one turn so now it is firing on #6 cyl and adjust the folowing valves: INT 3-4-6-8 EXH 2-5-6-7 . When adjusting the valves, loosten the adjusting nut intil there is clearance between the rocker arm and valve end. Then tighten it just until there is no clearance{you can feel this if you turn the push rod while you tighten the nut} then turn the nut 3/4 turn MORE. This will compress the valve and the lifter will compensate. You can adjust them with the engine running but the oil goes EVEYWHERE and sometimes catches on fire. GoodluckJoe

How large a surface area in units of square feet will 1 gallon of paint cover if you apply a coat of paint that is 0.1 centimeter thick?

A gallon of paint covers about 300 square feet at a usual thickness of one coat; your example of 0.1 cm thick is very thick coat, equivalent to about 6 coats of paint at least; you could cover about 300/6 =50 square feet at that thickness.


Why is there oil on your 1 spark plug on 350 Chevy?

The rings are gone. Or a cracked head. Do a compression test. Pressure should be around 140 lbs. Test all 4 on that side. If there is more then 10 lbs. diff. between all 4 you need motor work. To see if it's your rings or valves are bad. Get a squirt can with oil in it. After initial reading squirt about 6 squirts in plug hole , test again. If pres. goes up it's your rings. If it don't then it's your valves or head problems. Poss. valve guide covers also.


What is overlapping of valves?

Valve overlap occurs in a four-stroke engine at the end of the Exhaust stroke and at the beginning of the Induction stroke; and is when both the exhaust and inlet valves are open at the same time. At the end of the Exhaust stroke, the Exhaust valve is closing and the Inlet valve is starting to open in preparation for the induction of fuel and air into the cylinder. It is common knowledge that in vehicles that cannot alter the valve timing, the Inlet valve opens approx 6 degrees before top-dead-centre and the Exhaust valve closes at 9 degrees after top-dead-centre
