Morning Guys
I have had a garage look at my 911 sc engine just before Christmas to check it over. Engine is out of car and has been there a few weeks. I had just bought the car as a project.
Prior to the car being stripped for bodywork, the car was driven onto a trailer and the engine ran perfectly (I have videos of this), no smoke, maybe sounded a tiny bit tappety.
I have heard back off the place that has the engine and apparently all 12 valves have had it and need replacing and it needs a top end rebuild at a cost of around £8k.
I was really surprised at this as the engine sounded so sweet. So I have gone through the extensive file that came with the car and discovered that the engine had been out of the car less than 10,000 miles ago and had seals replaced (this was about 6 years ago). It also following this had a full rolling road dyno which I have the print out for showing 181 BHP. As this is a 1980 model, this is only 7bhp down on new.
Is it possible that this engine could have deteriorated this much in less than 10,000 miles? Unfortunately, without my go ahead the garage has gone ahead and changed all the valves......
Any thoughts? Could anyone tell from the video(s) of the car running whether all the valves were that bad? I do have close ups of the exhaust while the car is running showing zero smoke.
Any opinions appreciated. I'm not a mechanic, but these added costs could really give me issues in finishing the project.
