HarryS Posted December 1, 2017 Share Posted December 1, 2017 I set out to adjust the noisy rocker arms today and I'm not sure which is the intake and which is the exhaust. It is not obvious by the location of intake or exhaust port or the injector. The pictures in the shop manual are not clear either at least not to me. Can somebody get me over the hump. Thanks.
