[QUOTE="pollyp, post: 381112, member: 4527"] [CENTER][B]Feb 2009[/B][/CENTER] It’s been slowly losing coolant and traced it to the return pipe to the pump. This pipe was removed from the original engine and put into the new one and must have disturbed the o-ring seal [ATTACH=full]33334[/ATTACH] Cut old ring off [ATTACH=full]33335[/ATTACH] New ring from nissan sorted it [ATTACH=full]32037[/ATTACH] With the new engine sorted, I had nothing to do so during boredom I decided to completely clean the original one up just for the crack :p So cleaned the front [ATTACH=full]32036[/ATTACH] Cylinders [ATTACH=full]29051[/ATTACH] Crankcase [ATTACH=full]33336[/ATTACH] Oil pump cover [ATTACH=full]33337[/ATTACH] Insert pistons [ATTACH=full]29052[/ATTACH] Crank [ATTACH=full]26511[/ATTACH] The valves were layered in carbon deposits so I found that sticking em in a drill press with a small blade [ATTACH=full]33338[/ATTACH] Was able to scrape it off with ease and polish em nicely [ATTACH=full]30811[/ATTACH] Rebuilt head [ATTACH=full]33339[/ATTACH] Reassembled the original engine with goldenstars head. Was originally gonna sell it to a scrappy but decided to store it in the garage. If anyone wants it for £150, plus I have the original head which could be skimmed to replace goldenstars chipped head and a bag of valve shims to adjust the gap, p/m me Found oil in the plug tubes again, annoying. Swapping the original red cover with the newer engine cover did the trick. Seems you could only disturb the plug tube seal a certain # of times before they fail n leak. Can’t see a way of replace those seals cos the inside cover plate is bonded to the metal case forever [ATTACH=full]37469[/ATTACH] [/QUOTE]
