.... the last time i looked not all police were part of mensa?
All i can say is..... 4 seperate mechanics have looked at 2 different engines from HEC.... and all of them have said it is a shambles two of the mechanics had heard of heathrow engines and not for good reasons.... my experience backs this up, with customer service that makes faulty towers look A*.
If you want an expensive SCRAP engine go to Heathrow Engines.... if you want a RECONDITIONED engine dont bother.
