Sorry for replying to an old thread but I found it quite interested..
My xfire gets stored indoors in winter but I try and start it up once every month just to run a little fuel through the system... This last time I started it I noticed a rather loud ticking.. I figured it was from sitting for a while.. The ticking stuck around for a long while and only stopped once I turned the car off lol..
Hence why I ended up on this thread..
I am due for an oil change so i figure I should give the sea foam treatment a try..
My question is after doing the treatment should I do an oil change by removing the bottom plug or is doing it the suction from the top end ok too.. Just not sure if doing the top end suction would remove all the oil and seafoam mix?
