I have SLR 118 built in 2002. Had it now for 10 years without any engine issues. The engine has not been modified in any way or rebuilt at any time. Only having changed the ecu to Emerald. It's now done about 38,000 miles. I don't think the K engine is a worry. Some people just don't seem to like them probably because of the early issues. It is also a wet sump. Dry sump was an option i believe. I think early issues were something to do with the use of plastic dowels instead of steal ones which allowed the head to move.
