matt-k 0 Posted March 17, 2007 Hi, im steadily rebuilding a 1.9 Mi engine and theres a small dent right on top of No1 piston about 5mm in from the edge and about 1mm or so deep. It looks as if somebodys took a medium sized screwdriver and struck it with a hammer! Could this cause any problems or will it be fine? There are no other marks on the pistons and the valves are good to. Thanks Matt. Share this post Link to post Share on other sites
Higgy 0 Posted March 17, 2007 When I took my Mi engine apart (I bought it with snapped cambelt) there was a couple of dents where the exhaust valves had 'kissed' the piston tops. I rebuilt the engine and it has done 2k miles fine. (your engine sounds like it could have had a snapped belt in the past, or previous owner like hitting things with screwdrivers ). I would try and clean the dent up to make sure there are no other finer cracks coming away from it. I would say that its its just 1mm deep there should not be a problem. Higgy.
