yep, definitely, been drained and flushed 2x.
I think it is just one of those things...just a single lifter that has failed. If I had turned it off straight away and not turned it on again then there may have been less damage to the cam lobes but its hard to justify just stripping an engine to look for something because you "heard" a noise....had to start it up and run it again to see what we could hear....
All good though, I said to the miss's that she is getting a Cam and Lifters for Christmas!.....then asked what she was getting me

....lucky I didn't get a blackeye for Christmas haha
