Put another 50 miles on this afternoon and came back to change oil everything fine, atotal of about 175 miles on conversion. drained while hot changed filter , filled with 2050 hd oil cranked up and have a tapping in top end. Let run few seconds and cut off, tried again few seconds same, put old filter back on because it was hd and the new one was from napa ,cranked again same tapping on topend . I am afraid to leave running to long as to mess something up. I have changed it at least 20 times before with no problems. Help me out guys I won't be able to sleep tonite untill I can talk to someone at the shop that did the conversion tomorrow.
