Hondas are very good about Self Diagnostic codes being closely related to an actual problem, it is setting a code 22 its because the computer is not seeing the Front valve timing oil pressure switch open the curcut when it is suposed to be open, and due to the fact that it does not set this code everytime the motor is run says that more than likely there is not enough oil pressure at that switch when the motor is pushed hard, now this could be caused by eather the spoilvalve not functioning properly or that there just isnt enough oil pressure/volume at the Front head under hard/hot use, this may or may not be related to your overheat but if the front head is not getting the proper volume/pressure of oil its very possible that under load the friction is causing excess heat to build up, I would be curious to see a infered thermometer used on each head directly after track use to see if the front head is notibly warmer than the rear,also you can set up an oil pressure gauge on both heads and than watch them both on the dyno...Just some food for thought...JZ

[QUOTE="zahntech, post: 483963, member: 11939"] Hondas are very good about Self Diagnostic codes being closely related to an actual problem, it is setting a code 22 its because the computer is not seeing the Front valve timing oil pressure switch open the curcut when it is suposed to be open, and due to the fact that it does not set this code everytime the motor is run says that more than likely there is not enough oil pressure at that switch when the motor is pushed hard, now this could be caused by eather the spoilvalve not functioning properly or that there just isnt enough oil pressure/volume at the Front head under hard/hot use, this may or may not be related to your overheat but if the front head is not getting the proper volume/pressure of oil its very possible that under load the friction is causing excess heat to build up, I would be curious to see a infered thermometer used on each head directly after track use to see if the front head is notibly warmer than the rear,also you can set up an oil pressure gauge on both heads and than watch them both on the dyno...Just some food for thought...JZ [/QUOTE]
