hi all
first off, my bad for not updating in a while. As mentioned my ultrasonic went bang and it took a while to get to the point the seller was willing to refund the cost. While that was going on and while I was waiting for parts I decided that I wasnt totally happy with the level of clean I was getting on the cams, crank, IMS, heads and block so sent the cams, sprockets, crank and few other bits off to be superfinish'ed and loved the result, not just how shiny everything was (ooohhh shiny) but also because I could feel the difference on the lobes and journals with my hands and fingers.
To demonstrate, here are some before and afters of the crank and IMS
Crank straight out of engine
First clean via Ultrasonic tank
Second clean by hand
Superfinishing
Now, I completely understand that it is my responsibility to check, double check and ensure no media had entered any of the oil ways (I was also reminded by the company that did the work) and I did just that, and while I was using a number of pipe cleaning brushes and yes, media did drop out so it does pay to check.
