I went in for a valve cover gasket change. They were supposed to replace the whole gasket set, as talked about on the phone and as described on the receipt. That evening I thought it would be a good time to change the spark plugs. Two of the spark plugs wells was filled with oil. On top of that, it looks like they only changed one of the four tube seals. (As seen in the pic, only one looks new). They really should have replaced all four tube seals while they were in there, it’s part of the set, and especially if that was the cause of my slow oil leak. They used after market set, which is fine, but they charged $140 for the set alone! (After market sets are like $30/$40). Over priced and very bad job. Giving two stars because my family has had work done here in the past that wasn’t bad. Attached is a pic of one of the clean spark plugs wells in comparison to the oil-filled wells. The new tub seal was one of the wells that was filled with oil.
