The exhaust camshaft sheered off from the gear on my 88 Prelude 2.0 Si 4WS. I have found that autozone sells a replacement for $116 but is there anywhere else I sould try for a cheaper price? I'm not looking to gain performance. Also, I have searched many salvage yards, local and via internet, but to no avail. Any help would be appreciated. thanks.

What motor do you have? Give me the engine code, IE "H23A1"

It's a B20A5 motor ... 2.0L 1958cc dual overhead cams ... I've already taken the valve cover off and old exhaust cam out.

$116 isn't that bad at all for a cam. Replacement for mine are $430/pair.
Just go with that one man. I researched, couldn't find anything.
