I was referred to nissanforums.com through sentra.net. both are very useful to my two almost identical 94 Sentras. of course, I'll still drop by the org when I get bored.

and when I clicked the forum for the 1.6 engine.. the very first sticky was front oil seal replacement. I guess it's very common. the sentra I've had for about a year loses about 1 to 1.5 quarts a week.
