Often asked: What Gap Valves On 53 Ford Tractor?

What is the valve clearance?

What are valve clearances? Valve clearances on motorcycle and car engines effectively relate to the gap between the top of the valve stem and the cam that operates it. The inlet valves in the engine open to allow air and fuel into the cylinder, while the exhaust valves let the burnt gases out.

What happens if Valve clearance is too big?

Too much clearance means the valves will likely clatter and, over the long term, cause damage to the valves, camshaft lobes or rocker arms. If there’s too little valve clearance, the valves won’t fully close, causing excessive heat, and the engine will lose power.

The clearance is correct when the gauge is a close sliding fit between the two parts. If the clearance is wrong, either the blade cannot enter the gap or it is loose, so that you can move the rocker up and down with the blade in place.
