I recently got done re-building a lot of my 1980 terra and have been using it as a daily driver for about 2 weeks now. In the last few days I have noticed that I have been using a lot more fuel driving around town, I checked the turbo and it seems like the intake is sucking (excuse the pun ) a lot less than it was when I first started driving it around.

Also, I had to replace the alternator with an after-market one, and in-order to get it to start charging I have to "rev the engine every time I start the car to excite the alternator", said the guy at the alternator/starter shop. Being new to diesel engines... I don't think thats very good for it. If I dont rev the engine way up, it runs really smooth... but I kill my battery; when I do rev it way up, the engine idols really really heavy and all sorts of other sounds start going, yet it still runs fine.

Any advice that anyone can give me would be greatly appreciated...
