has anyone had experience of these sticking open and not passing to the cooleri think this has been one of the contributing factors in killing my engine  just stripped the plate down to clean it and the shuttle part was stuck in the bypass tube thus only letting oil bypass the cooler not flowing to cooler |

So you must have seen the engine temps rise to a dangerous level?________________________________________ See the sheer power and might of the lesser known burrowing owl. |

I saw 130 on the oil water temp was good though....anyway this was i think one of two or three factors to my engines rattleI have been experimenting in the kitchen! boiling and cooling the mocal plate  i was right! the shuttle is sticking in the plate and not closing after taking it apart you could see high points and marks where the shuttle was sticking     i have now cleaned up the rough castings around the port hole and have also slightly shrunk the diameter on the shuttle it is now moving more free to the full stroke |

Got the same sandwich plate on mine... Just feel the 19row cooler when on track days just to make sure it's very warm / Hot & flowing & working ? Always wonder it it's working 100%? Good work Paul  |
