Product Overview
Description and purpose of the part The repair kit for the crankcase ventilation valve (CVVV), built into the valve cover of the Opel 1.7 CDTI, consists of a membrane, a cover and a spring. The membrane, together with the spring, regulates the vacuum in the crankcase ventilation system, and the cover secures the working elements in the valve cover body. Damage to the diaphragm or malfunction of the valve can cause whistling, air leaks, unstable idling, increased oil consumption and incorrect crankcase gas pressure. Complete set: KVKG membrane, cover, spring. Membrane diameter: 49 mm. The repair kit is used for Opel 1.7 CDTI valve covers with numbers: 97363851, 98084782, 5607603, 0607898, 5607143. When it is worth checking the valve cover CVKG: there is a whistle or extraneous noise in the area of the valve cover; the engine is unstable at idle; excessive vacuum occurs or the pressure in the crankcase is disturbed; increased oil consumption is observed; an air leak appeared through the crankcase ventilation system; diagnostics show violations of the mixture composition associated with leaks in the crankcase ventilation system; the KVKG membrane is damaged, torn or has lost elasticity.

Important! Before ordering, compare the OEM/P/N and design of the installed valve cover with the data in the description. It is also recommended to check the membrane seat and the condition of the KVKG housing. If the valve cover body is cracked, deformed, or has other mechanical damage, installing a repair kit may not be enough. FAQ What is included in this repair kit? The kit includes a KVKG membrane with a diameter of 49 mm, cover and spring. Why do you need a membrane with a spring? The membrane and spring are involved in regulating the vacuum in the crankcase ventilation system. If the membrane is damaged, the operation of the KVKG is disrupted, which may be accompanied by a whistle, air leaks, unstable idling and increased oil consumption. Do I need to replace the entire valve cover? Not always. If the valve cover body and the KVKG seat are not damaged, the faulty valve elements can be replaced separately using a repair kit. Why does the kit include a new cover? The cover holds the membrane and spring in position. The repair kit allows you to replace not only the membrane, but also its fastening elements in the KVKG unit. How to check the compatibility of a repair kit? Compare the number of the installed valve cover with the numbers from the description, and also check the design of the assembly and the diaphragm diameter of 49 mm.
