Working on an engine rebuild or just doing a valve job? This BGS 1741 Suction Valve Grinder is the classic, simple tool for the job. It's used for lapping (grinding) engine valves and their seats together by hand to create a perfect, leak-proof seal. The tool itself is straightforward: it has a comfortable wooden handle that's 220mm long. On one end, you get a 28mm diameter rubber suction cup, and on the other end, a 34mm cup. These different sizes let you work on a range of common valve sizes. You simply press the appropriate suction cup onto the face of the valve head, and the vacuum holds it in place. Then, you use a back-and-forth twisting motion (often with some valve grinding compound) to lap the valve against its seat in the cylinder head. It's a fundamental tool for any DIY mechanic or small engine repair shop. It's durable, offers great value for money, and is essential for ensuring your engine has good compression. A timeless tool for a timeless job.
