How much side to side play should be in the drive gear of the oil pump? |

Okay, so there are gear marks in the housing, so I'm just going to assume that there's too much play. How the heck do I get the drive gear loose? I can't get the nut on the timing belt side to come off. |

if you are looking to replace the gears inside the housing you will need to pull the lower t-belt cover off. and remove the 10or 12mm bolts off and pull it thru. i have a extra one here that you are more than welcome to. the oil pump was replaced when i rebuilt the 4g63. so it has about 10K on it. well if they are the same as 4g63 |

The drive gears should be the same, but I don't think that the front cover is? I could be off. How do you break that 12mm nut loose on the drive gear? I've done everything short of trying to put the gear into a vise and going from there. |
