I have searched the forum on this topic. The two threads that I found related mostly to the problems of high oil temperatures for some planes while flying.
I installed the oil cooler to my lower cowl and have installed the cowl to the plane. The oil cooler is hard against the muffler. I had help from an aircraft mechanic to do this.He suggested I may be able to rotate the muffler rearwards by adjusting the exhaust pipes slightly. I spent the afternoon trying to do this but I feel they seat in only the straight in position. There appears to be room for the muffler to be moved rearwards by adjusting the length of the exhaust pipes. The other option is to modify the cowl. The mechanic ask me to check the distance specified in the plans. The two threads have had posts about the gap but there does not appear to be a distance specified on the plan or in the threads.
I installed the cooling duct to the lower cowl as supplied. The cooling duct is supplied moulded to shape and although it has to be trimmed that trimming does not affect this distance.
I am looking for some comments on ways to sort this out. I can also email Vans for the spacing measurement.
Cheers
