billrigsby Posted June 7, 2009 Share Posted June 7, 2009 When doing the leakdown test on a 2.2l, what position should the cam sprockets be in. All valves need to be closed, is that the position you use when installing a new timing belt (ie. both marks at 12 o'clock? What position should the crank be in, also 12 o'clock?

porcupine73 Posted June 8, 2009 Share Posted June 8, 2009 This is the perfect application for the arrows on the LH cam sprocket. Arrow each 0 90 180 270 deg position is tdc for one of the pistons. you'll know if it isn't the one you're working on as air will be leaking out intake or exhaust.

That is assuming the timing belt is intact. You did not see the tread about the siezed idler pulley. I guess the valve covers need to be off to determine valve location. Finding TDC will not be a problem with the plugs removed. Bill Quote Link to comment Share on other sites More sharing options...
