Can anyone tell me what year engine I have in my Maxima. I had a replacement long block installed by a dealer years ago in my 1989 max - 3.0L SOHC. I've run into problems with replacement parts (timing belt - teeth pattern, etc) and without knowing the year, I,m stuck. The number on the engine block is VG30R904334X. I asked a local Nissan dealer, but they were of no help.
