Basically get a double rollmaster, not a JP timing set and also match the crank gear with your stock crank gear, especially focusing on the inside chamfer.
ClubGP Message Forum troubleshooting
Right, it's been found that there's were a lot of issues from not understanding the issue and installing incorrectly because many thought the sets were good for US motors as well as Aussie motors. Yet the issue ended up being that difference.
from my understanding, the JP and rollmaster sets are the same and they have been for a while, right? why would it make a difference so long as all the variables are checked before the motor is sealed up?
i personally ran a JP set straight out of the box (not chamfered correctly) with a shaved down oil pump cover for around 30k before i sold my car still running with it. luck of the draw?
Is there anyone that has pictures of the correct setup?
The rollmaster and Jp are different, the JP being a 2 piece crank gear and also has a different pitch on the chain, making them non-interchangeable. There was a thread on clubgp that focused more in depth on the exact differences, but the search function sucks and I can't find it. Someone -either Janice or Farnsworth had pics and specs of all 3 sets including stock and measurements. The JP set was more off than the rollmaster, possibly in more than one way. The Rollmaster was just easier to fix and is more reliable of the 2 so far.
THere was a thread on clubgp, although even though i call myself an expert searcher on that forum, I can't find it. That forum software/support hasn't updated anything since 2001.
