The warranty work for the starter was good. The response for the oil leak was unsatisfactory. Less than 1000 miles after having the timing chain and oil pump replaced, I asked for the oil leak to be checked. I have owned this S10 since September 1995 and have always parked it in front of my house. There was never a sign of oil leakage until this work was done at Carmasters. When the work was done, Mike called me and asked if I would authorize replacing the rear main seal while they had it open and I said yes. When I picked up the vehicle, Mike said that they did not replace the rear seal as it looked good and it showed no signs of a leak. The front seal was or should have been replaced with the timing chain replacement. Now you say the oil is leaking form the front seal and even more from the rear seal and I need to live with it and add oil as needed or replace the engine because of blow by. Blow by does not always mean that a new engine is required. It can be caused by a problem in the PCV system. I do not find this acceptable as a solution to a problem that I believe was caused by work done at Carmasters. I know times are slow, but I have been unemployed since March 1, 2013 and cannot afford to subsidize slow business. I know that you previously recommended a dye to find oil leaks, but when I checked for oil leaks prior to bringing the vehicle back to you, I found a bolt missing from the timing chain cover which caused the oil around the oil pan and did not show visible signs of leakage in the street. I had provided all of the gaskets and seals for the timing chain and oil pan when I brought the vehicle in. When I found some of the gaskets still in the cab when I picked up the vehicle, Mike told me that Carmasters had gotten an entire set of gaskets and seals under warranty from the first timing chain job that was done there. I have given you a lot of business over the years with many vehicles, but I may not come back in the future.
