Signs that it is time for new cylinders include low compression on one or more cylinders, oil consumption, blue smoke, blow-by from the breather, piston slap when cold, and cylinder walls that are scored or pitted when you take the heads off. Many Vanagon owners rebuilding a tired 1.9 or 2.1 use the opportunity to go up a size for a little more torque. A 95 mm kit on a 1.9 or 95.5 mm on a 2.1 adds a modest amount of displacement with stock-style cast parts, which suits a heavy camper.\u003c\/p\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCheck bore, stroke and engine code before ordering.
