You did not notice any additional vibes running thru it? 

Too soon???

curious...you have an oil pressure issue,running hot and loss of power and you dont mention case split and visually checking crank,main bearings and big ends......sounds risky to me.jmho.cheers

A question Locadd,

did you work out the reason for the overheating and low oil pressure?

I wouldn't think a tired top end would do that, but I'm no mechanic.

Roo.

i should have asked the same roo,thought it but didnt ask.there has to be reason for all issues.
