That's great! I wish we had done the water pump on my son's car ourselves. We took it to a mechanic and paid $2600 to have the water pump done with new timing chain. Of course, an oil change was part of that work along with a coolant drain and refill. About a week (200 miles) after we got the car back it began blowing a THICK cloud of white smoke. Also, when driving it felt very anemic with no noticeable turbo pull. Of course the first thought was a smoked turbo. Since we were following up on PTU maintenance and needing to pull the downpipes anyway I figured we'd inspect the turbos at that time. Rear turbo, no evidence of oil or excessive play. Front turbo, had to remove the oil filter to access the mounting hardware for the cat (no evidence of oil or excessive play). When I pulled the oil filter I noticed the oil was black as night! Also, the oil filter was not replaced with the "oil change". I took a sample of this 200 mile oil outside and looked up through it at the sun and couldn't see any light whatsoever. So we completed the oil change, re-mounted the exhaust components, and took it for a test drive. Amazingly, no smoke and the thing was pulling strong again. I've sent a sample off to Blackstone for analysis and will see how much coolant remained in the oil. We've been in contact with the repair shop and they refunded the money we were charged for the oil change as well as for the oil we put in it. Long story long...do anything you can in the comfort of your own garage and with the assurance that it will be done right. Sorry for the hijack. Just wanted to give props on doing your own service and repairs. Next time I'll be doing so for sure.
