BLiNK Motorsport Posted October 13, 2013 Share Posted October 13, 2013 Yes, I think an OEM timing belt needs to be tried - we stopped using IL Motorsports Parts some time ago now and only fit Mazda Parts. Lets keep our fingers crossed. Gary - the timing belt was fitted as per workkshop manual so was the correct tension - if it's loose now then it has also stretched?

darve Posted October 13, 2013 Author Share Posted October 13, 2013 thanks Fraser. belt must have stretched. looking at pic 2 in post #6 the engine it's at TDC and I hadn't loosened the tensioner and that is with the old head on. it was not that lose when I built the car. can't see it being anything else now I've spotted that pic with the engine at TDC Quote Link to comment Share on other sites More sharing options...

BLiNK Motorsport Posted October 14, 2013 Share Posted October 14, 2013 Dave, you could also try some motor factors - won't be OEM but will get you through until you can get hold of an OEM belt. HTH Quote Link to comment Share on other sites More sharing options...

BLiNK Motorsport Posted October 14, 2013 Share Posted October 14, 2013 Dave - one other thing to check...... The belt can become 'slack' depending on where you are in the crank/cam cycle. When you install the belt (no.1 @ TDC and timing marks on the pulleys are vertical), you are then supposed to rotate the crank pulley 1 and 5/6ths turns to bring it to the correct point in the engine cycle to set the tensioner pulley. Try doing this - there is a mark on the oil pump where 5/6ths of a turn is...or about 11.00 on a clock face. So...spin it round 1 and 5/6ths turns and then see what the tension is like between the pulleys (should be relatively tight).
