R34 Fuel Tank Leaks
The R34 has a saddle tank above the rear subframe, and behind the rear seat. It is an L shape. It shares a lot of commonality with the R33, S14, and S15 fuel tanks. They can leak. We have learned this lesson the hard way, and now check each car before it comes to the US. If you have a car with leaks, after checking that its not something like a line, it is probably here at this sensor/vent.
The tank is double layer, so fixing it is not, will not be an easy task.
Some other common R34 Skyline and R34 Skyline GT-R problems.
The MFD displays often crack and go bad. Nearly every recent R34 we have seen, has a bad MFD. However there are replacements available. There are two different normal screens. So make sure you know what you have. ~$300 http://bit.ly/R34-MFD
Getrag. The R34 Transmission. The V160 6 speed. The Getrag is similar to the transmission used in the MK IV Toyota Supra. The input shaft and main shaft are unique to the GT-R on both transmissions, the rest of the internal parts are interchangeable. The Getrag is loud at idle. The synchros aren't that durable. Even though the Supra guys run them pretty hard, we break weird hard parts in them. All wheel drive can put a hurting on a transmission. The prices for the Getrag are getting up over 10k a trans. With the parts gettting harder and harder to get, a sequential almost starts to look appealing. http://bit.ly/V160-R34
Seats. The stock early seats are grey. They are a great seat. High bolsters, special fabric with grip spots on it. The later seats are black. Both seats are highly desired, with the later seats being even more sought after. The bolsters wear like the R32 and R33 before it. As far as we know, the fabric is not available. The current prices seem to be $5k-$10k for a set of black ones. The seats fit R32, R33, and R34 GT-R, and all the S chassis with minor modifications. http://bit.ly/R34seats
Jack points and rust. Like the R32, and R33. It is easy for someone to jack an R34 incorrectly, and damage the side sills or pinch welds. This can also be a ripe area for rust. So check them. Cheaper cars will probably be damaged here. More expensive nicer cars, should have good pinch welds.
