It seems a trend. Standard replacement parts which are so bad that if can wreck you car. Engine parts, electrical stuff or mechanical stuff in general, it seems a trend. So bad that I was scared to order an replacement oil pump for my coming engine build. Hence the reason I bought an oil pump that has been build to a high spec. The pump is a standard pump which has been dismanteled and the bad quality parts taken out to replace with the correct part. All parts are measured and produced to the correct tolerances, call it blue printed if you will.
