Dead 1330 on my F3-S...

[wanderingman]

Got the word today oil pump failure. Lots of internal damage. Broken oil pump shaft, bent and broken valves, piston damage, and damaged bearings. I guess the transmission is supposed to be ok. Waiting on BRP to deside what they are going to do.

I am having trouble understanding this one. A failed oil pump will cause failure of any surface that moves against another surface, but an explosion? Obviously the components were moving as you were cranking the engine. The boom you heard had to be fuel exploding. To me I am inclined to believe that the cam was not turning, (broken cam chain or belt) and the engine fired with an intake valve open. This could also account for the bent valves. I don't know if the 1330 is an interference engine or not, but I suspect it is, due to the published compression. It also is very likely that the oil pump is driven off of the cam. I made my living trouble shooting problems and doing field service for a major manufacturer of turbine engines and I guess it has become an additction.

Looks like the oil pump shaft broke. It's gear driven.

At least they found the problem, and the mew engine is being installed...

Ugh... They never ordered an air intake to replace the broken one. Now I'm waiting on that...

Looks like all the parts came in on Friday. Hopefully I'll have it back Wednesday morning...

That's good to hear - back on the road Friday. I had a friend who liked wearing hot pants so much that her bike caught on fire.....
