Buying with IMS replaced

It also begs the question about the $$ 'solution' option (oil pumped into bearing-less 'bearing')? Nedlands is right: What are you supposed to do? Doing it could be bad, not doing it is bad, metal shavings after doing it is bad .... bad bad bad.

Using an "open"style bearing such as the LN or some other retrofits on an engine with circulating metal debris quite often leads to very quick failure of the new IMS bearing. If the pre retrofit inspection finds metal, we stop the process and will not move forward. If the engine is full of metal, it needs to come out an apart for a full rebuild. Installing a new IMS bearing is throwing money away.
