The box shows clear signs of storage: rub marks and paint abrasion on the top, knocked edges and corners, tape residue and a yellowed strip of tape over half the label – the print is faded in places but fully legible. The 12 sealing rings made of brown FPM are unused, with clean sealing lips and visible steel garter spring band, only with some storage dust; plus 6 unused transparent installation sleeves with a red marking ring. This is elastomer around 30 years old; FPM is considered storage-stable, but a residual risk remains with material this old. The part is sold untested.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch3 style=\"margin:22px 0 8px;\"\u003eFunction and location\u003c\/h3\u003e\n\u003cp\u003eThe valve stem seal sits as a miniature shaft seal on the valve guide and wipes the engine oil off the valve stem as it moves up and down. It allows only a defined lubricating film through and prevents oil from being drawn into the combustion chamber or exhaust port. Hardened seals are a classic wear issue on the M103.\u003c\/p\u003e\n\u003cp\u003eIt is fitted in the cylinder head on the 12 valve guides (6 intake, 6 exhaust), below the valve spring and spring retainer. Replacement is done with a valve spring compressor with the camshaft or rocker shaft removed; the included installation sleeves protect the sealing lip when sliding it over the keyway grooves.\u003c\/p\u003e\n\n\u003ch3 style=\"margin:22px 0 8px;\"\u003eHow can you tell hardened valve stem seals?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlue smoke on cold start\u003c\/li\u003e\n\u003cli\u003eBlue smoke after overrun or at traffic lights\u003c\/li\u003e\n\u003cli\u003eIncreased oil consumption\u003c\/li\u003e\n\u003cli\u003eOil-fouled spark plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"margin:22px 0 8px;\"\u003eCompatible vehicles\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eW124 sedan, S124 wagon, C124 coupe (1984–1997):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e260 E\u003c\/li\u003e\n\u003cli\u003e300 E\u003c\/li\u003e\n\u003cli\u003e300 E 4MATIC\u003c\/li\u003e\n\u003cli\u003eE 300\u003c\/li\u003e\n\u003cli\u003e300 TE\u003c\/li\u003e\n\u003cli\u003e300 TE 4MATIC\u003c\/li\u003e\n\u003cli\u003e300 CE\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eW201 190 series (1982–1993):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e190 E 2.6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eW126 S-Class (1979–1991):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e260 SE\u003c\/li\u003e\n\u003cli\u003e300 SE\u003c\/li\u003e\n\u003cli\u003e300 SEL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eR107 SL (1971–1989):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e300 SL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eW463 G-Class (1989–2001):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e300 GE\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe manufacturer number is Elring 764.027, the corresponding Mercedes-Benz OE numbers are A 103 050 01 58, 1030500158 and 1030500067.\u003c\/p\u003e\n\n\u003cdiv style=\"background:#f5f6f8;border-left:4px solid #c69a3a;border-radius:8px;padding:14px 18px;margin:0 0 16px;\"\u003e\n\u003cp style=\"margin:0 0 6px;font-weight:700;\"\u003e⚠ Important: compare the part number before buying\u003c\/p\u003e\n\u003cp style=\"margin:0 0 6px;\"\u003eSimilar sets exist with different end numbers.
