Valve Adjustmentin Batumi

Valve adjustment in Batumi at PRO SERVICE (Airport Highway 212): on a cold engine we measure the clearance of every valve with feeler gauges, compare it with the manufacturer's spec and set it with adjusting screws or new shims. From … GEL, takes 2-4 hours. Before the job we check if your engine needs adjustment at all.

Which engines need it

Only engines without hydraulic lifters need adjustment — the gap between cam lobe and valve is set mechanically and changes over time. Such engines are common in many Japanese and Korean cars and in a number of diesels. If your engine has hydraulic lifters there is nothing to adjust; a tick there means checking the lifters and oil pressure.

The check interval is in the manufacturer's schedule. On a used car with unknown history, checking the clearances right after purchase is sensible.

Signs of wrong clearances

• Too much clearance: a sharp, fast ticking from the top of the engine, louder when cold; less power because the valve opens less.
• Too little clearance (tight valve): no noise, but the valve does not fully close. Rough idle, hard cold starts, low compression. This is the dangerous one: the exhaust valve overheats and burns — then it is a cylinder head repair.
• Smoke or popping in the exhaust, higher fuel use.

How we do it

1. Let the car cool down: clearances are measured on a cold engine.
2. Remove the valve cover, coils and anything in the way.
3. Turn the crankshaft by the marks and measure each valve with a feeler gauge, writing down the results.
4. Screw adjusters — loosen the locknut and set the gap. Shims or buckets — calculate the required thickness, remove the camshafts if needed and fit new shims.
5. Re-measure, new valve cover gasket, reassemble.
6. Start-up and check for noise, misfire and fault codes.

You get the measurement sheet: it shows which valves were out of spec. If the valve cover gasket is leaking, we replace it on the same visit — the cover is off anyway.

What affects the cost

• Adjustment type: screws are quicker, shims often mean removing the camshafts.
• Number of valves and heads (inline four or V engine).
• How many shims need replacing and whether they are in stock.
