Properly Matching Your Camshaft and Distributor Gear
Matching camshaft and distributor gears is one of the most critical, yet often overlooked step in engine assembly. The proper distributor gear for your camshaft differs by both the material and the kind of lifter for which your camshaft was designed. Using the wrong material can lead to premature gear wear, possible camshaft wear and
1998-2002 Honda 3.2L V6 Camshaft Subgear Preloading
The1998-2002 Honda Passport (3.2L) V6 engine has a “non-interference”design. This means the valves never contact the pistons, even when thevalves or camshafts are not correctly timed, or even if a valve isfully open and its piston is at top dead center (TDC). • The ratio between the camshaft drive gear and the camshaft gears is1.33
Understanding Valve Design and Alloys
To the naked eye, a valve is a valve is a valve. Sure, there may be two, three, four or more of them in the cylinder head, but unless you have x-ray eyes, one alloy looks pretty much the same as another. The importance of coatings to today’s valves should not be overlooked, of course.
Choosing A Replacement Camshaft
Unless you are doing a totally stock rebuild and reusing the original camshaft, selecting a camshaft depends on what kind of engine you are building and how that engine will be used. A stock engine for a daily driver is obviously an entirely different application than an big stroker motor for a Pro Stock racer.
