90_EAGLE_TALON Posted September 18, 2006 Report Share Posted September 18, 2006 The timing belt is set on my car but the spark is hitting too soon does anyone know the proper way of setting the ignition timing on these cars? My car is a naturally aspirated 2.0 Liter dual over head cam engine from a 1991 mitsubishi galant gsx. I would really apreciate the help. Thanks!!!

351mach11647545510 Posted September 19, 2006 Report Share Posted September 19, 2006 don't know much bout this, but is everything lined up right? Quote Link to comment Share on other sites More sharing options...
WWD JUNK Posted September 19, 2006 Report Share Posted September 19, 2006 Are you using a timing light? The timing advance is set by grounding the ECU via a plug on the firewall, and then adjusting the CAS accordingly. This is of course provided the timing marks on the cam gears line up - - - -, and with the dowels up the crank is at TDC. Quote Link to comment Share on other sites More sharing options...
Mike C Posted September 20, 2006 Report Share Posted September 20, 2006 Set the base timing to 5* BTDC by moving the CAS (the rotating sensor on the end of the intake cam). Use a timing light to reference the crank pulley against the 5* located on the timing belt cover. Quote Link to comment Share on other sites More sharing options...
90_EAGLE_TALON Posted September 21, 2006 Author Report Share Posted September 21, 2006 we had done the timing and everything the engine ran fine but after appx. 80 miles of starting and shutting the car off i shut the car off in london and it wouldnt shat again. when the car was towed back home the timing was found to be off at the belt again. Any ideas why it would have jumped time with a new belt, no balance shafts (the whole engine has been balanced)? Quote Link to comment Share on other sites More sharing options...
Mike C Posted September 21, 2006 Report Share Posted September 21, 2006 Did you install a new hydraulic tensioner or reuse the old one? Same question on the tensioner and idler pulleys. Quote Link to comment Share on other sites More sharing options...
WWD JUNK Posted September 21, 2006 Report Share Posted September 21, 2006 If a new hydraulic tensioner was installed, was it tensioned properly? Quote Link to comment Share on other sites More sharing options...
90_EAGLE_TALON Posted September 21, 2006 Author Report Share Posted September 21, 2006 it was a new hydralic tensioner and it was installed properly but the tensioner assembly and the idler pulleys were reused Quote Link to comment Share on other sites More sharing options...
