So I put engine on workbench and began disassembling it in February 2013 . There was nothing worrying at first glance. Camshaft was in good shape, without signs of oil starvation.
I have an idea, that reason for this lies in fuel tank liner. In fact tank was covered from inside twice. First time it was done with poly-something liner long time ago in Japan. Secondly it was recoated with red iron oxide in Ukraine, after SRX was imported, due to pre-selling maintenance. I think that iron oxide coating could be slowly dissolved by gasoline and then could be baked in intake channels, on valves and other surfaces under heat exposure.
But these difficulties had to be solved anyway. As for scratched bush of connecting rod, after much thoughts and consideration I decided to bought new rod kit and to repair crankshaft with it. The best one I could find on ebay was T.K.R.J connecting rod kit. I received the parcel with it in March 2013.
But before crankshaft could be repaired it needed to be ejected from crankcase. And I got yet another difficulty at this point. I found out that rotor nut was stuck, firstly. I managed to remove it only after heating and using electrical impact wrench. It turned out the rotor itself became another disappointment. It not only needed special puller, but stuck on shaft also.
Procedure of crankshaft repairing required to use press and some special stuff and skills I hadn’t, so I gave it to expert.
To be continued.
