Not worth the trouble. On a recommendation from our local parts store, we sent a cylinder head out as it had a slight misfire at idle. On removal and saw the seat was partially sticking out from the head. On the recommendation from Frank at the machine shop he replaced all the exhaust seat , not just the one in question.On installation after six hours worth of labor, gaskets, oil and anti freeze,, on start up the number four cylinder now misfires all the time with heavy oil consumption. After doing a leak down test,compression test and running our findings by a paid diagnostic venue,we came to the conclusion that it had a head issue that we never had before. We sent to head back down to Frank and was supposedly thoroughly check to find it there was no issue with his job so we put the head back on the car. Obviously it was the same issue , heavy oil consumption and missing number four cylinder. We double and triple checked our work along with a call to our automotive diagnostic hotline to come to the same conclusion that it was a head issue. We bought a brand new head from Mini and the problem is cured. At this point right now we are asking for just our money back , as we will eat the 16 hours in labor and parts… with no response from this company . Poor workmanship and poor customer Service !
