valve clearance

Should the valve clearances be adjusted hot or cold? 2.

I believe oil change, including filter and adjusting or checking valve clearances every 3,000km.

The engine featured a revolutionary new method for adjusting the valve clearance.

On several occasions I set valve clearances to specification but still found them noisy.

Other changes also meant that the standard valve clearances were reduced, possibly through tighter manufacturing control.

I then checked the piston to valve clearance and decided on a setting centreline.

Block may require relief grinding to obtain valve clearance.

I checked the top end and reset the valve clearances but the misfire continued.

However, RC36 engines have been known to reach well over 50,000 miles without any need to adjust the valve clearances.

I'd check the valve clearance adjusters and the carbs first, then think about lifting the head if you find nothing else wrong.

To adjust the valve clearance in the generation 1 and 2 a shim over bucket system is employed.

Valve clearance was adjustable by screws and locknuts on the rocker arms.

Check the valve clearances before assuming the worst, they may have closed up to zero and be causing a compression loss.

It is a myth that in certain circumstances, a lifter can "pump up" and create negative valve clearance.

I turned over the engine and bent a push rod (I had not adjusted valve clearance).

For example, shims are inserted into or under bucket tappets to control valve clearances.

Ended up that the valve clearances were too tight - caught it before the valves were burnt though.

It must be stressed however, that the valve clearances need to be checked and re-set if necessary.

The engine needed frequent valve clearance adjustment.

Check these before you adjust the tappets as if the head bolts need tightening, this affects the valve clearances.

Another departure from the Z1 engine design was the use of a shim-under-bucket method of setting valve clearances.

The valve clearance is adjusted using shims.

The engine was tuned accordingly, with optimum settings for ignition, carburetion and valve clearance.

The work necessitated careful checking of the valve clearances which meant that the shims needed skimming to size.

Checks of valve clearances and transmission oil levels highlighted no faults but a possible problem with dragging brakes couldn't be ruled out.
