New to this but my van is blowing blue smoke and I've been told that I need a new engine. Spent a lot of money on a conversion so have to get it done. I have seen Remanufactured engines on sale for 2k then would need to get it fitted. Have now found a guy who says that he could source an engine and fit for approx £1000-£1200. He said he would clean and check the new engine and replace parts not working. Does this sound reasonable? Any advise appreciated.
