6x Intake Valve for PORSCHE 993 Carrera 272PS turbo 49mm SM 99310540902 SET Made in Germany Description: Components in the valve train are subject to high stresses at fluctuating temperatures. Controlled by the camshaft, the valves are actuated via the rocker arms. Clattering/knocking noises, especially when the engine is cold, are signs of worn components in the valve train or incorrectly adjusted valve clearance. During an engine overhaul or maintenance, worn or damaged components must be replaced immediately to prevent consequential damage. In addition to intake and exhaust valves for various Porsche models, we offer many other engine parts and spare parts. About the Brand: Since its founding in 1987, SM Motorenteile has focused exclusively on the manufacture and distribution of engine parts.
