We'll lets see what happens here. Jaba has said that no such thing as a rotating valve seat. Walter deflected from answering. Now Walter knows there are. So what dose he do say yes or say no. So what dose that say about the so called experts. Now remember this started after I was ask a question. Let's see what happens.
Now this one engine is not the only engine with these seats. However it can be brought new now. And is stc in one other aircraft that can be used for charter type ops.
Funny how I know f all isn't it.
Cheers
Awaiting the results.
