As some of youmight know, I blew my honda up in Vegas earlier this year, rewbuilt the head and left the bottom end alone based on some bad advice from some of my close associates..(my guys that help me), and then we went to MV, I got to drive it on that Thursday of last week and blew it up again. I at least now know what happened and we will fix it correctly this time.
I'm quite pleased with my past performance of my F-Motor, I found out that by listening to others whom I assumed had more knowledge than I did of this motor led to my motor's dimise. If I had stuck to my original build plan, I think I would not be having the issues that I am now having.
I now know that by adding the thicker head gasket to lower the compression on the motor and also adding an aftermarket cam chain tensioner, I over stressed the cam chain idler gear bushing (#10 in the diagram), which failed and caused the cam chain gears to go all out of alignment and destroy my nice new head! Plus, the number 4 rear piston that got a "slight" bit of damage in Vegas was actually alot worse than we thought and I should have gone ahead and done a complete rebuild, but lesson learned.
We will tear this motor down, salvage what parts we can, take my original record setting motor and rebuild it, and be back in business before the October 1/2 mile races in Ocala.
