Valve Adjustment — with thermal clearance measurement

The engine has a valve knock, especially when cold, runs unevenly, or the adjustment is due under the maintenance schedule. We remove the valve cover, measure the clearances with a feeler gauge and set them with screws or by selecting shims, then fit the cover with a new gasket. The job takes from 3 hours.

“Valve Adjustment”: from the first signs and checks to approved work and the final quality check.

What becomes clear

Valve clearances to the manufacturer's data

You get the clearance readings before and after adjustment, and the car with a new valve cover gasket.

  • Clearances on every valve to the manufacturer's data
  • A new valve cover gasket
  • Clearance readings before and after adjustment
Price and time

From AED 630From 3 hours

Labour price including VAT; parts and consumables are paid separately.
Scope of work

The final cost depends on the engine and the adjustment method: screws or shims that need ordering. If the engine has hydraulic lifters, it needs no adjustment, and we tell you so before we start. Starting labour price from AED 630.

Questions before you book.

Straight answers about the inspection, approval and next step.

How often do valves need adjusting?

According to your engine manufacturer's schedule, or sooner if a knock appears. Engines with hydraulic lifters do not need adjustment.

Too small a clearance leads to valve burnout, too large a clearance leads to knocking and camshaft wear. Repair after that costs more than the adjustment.

From 3 hours. If shims are needed that are not in stock, the time depends on their delivery.
