kingkenny100 0 Posted June 12, 2013 (edited) hello, I am having a major headache with a rebuilt engine. I spent months rebuilding, polishing, painting....and was slowly running in. After around 400 miles, something gave way and a tapping sound started. It had lost some power and obviously pulled over immediately. on inspection, the head did not appear to be getting oil, so I took off the sump, and the (new) oil pump found some small pieces of alloy in the gauze. I thought this (although minor) might have been what was restricting the oil getting to the head and put on a new oil pump. (also checked the crankshaft and bearings which all seemed fine). There is plenty oil getting to the head now so that does not apeear to be a problem The sound however is still there I thought it could be the tappets and so have left it runningfor a good while to fill, but the knocking does not go away and increases when under pressure/and I think gets worse as the oil heats up. It sounds tappety and on the left hand side, so I took out the 11 tappets that I could reach easily and they all seem to have oil in them – I refilled them and put them back in. Still the same noice! Any suggestions welcome?? Thanks Kenny Edited June 12, 2013 by kingkenny100 Quote Share this post Link to post Share on other sites
science 0 Posted June 12, 2013 Have you bled the chain tensioner bolt? It may have air in it after rebuild and especially after oil starvation. After bleeding, I would take the rocker cover off and turn it over by hand to see how the chain tension is. Quote Share this post Link to post Share on other sites
