RB26 - Nissan Skyline GT-R Oil Leaks

The hot side of an RB26

The RB26 is not the most simple engine on earth. There are lots of places for an oil leak. Here are a few of the most common engine oil leaks.  Although along with engine oil you can have front diff leak, power steering, transmission, transfercase, ATTESA system, and rear end leaks.

The first easy one.  When you change the oil on an RB26, oil will often leak and pool on the top of the front diff.  Do your best to clean it off, otherwise you might be hunting something that isn't there, when you see a little puddle under your car.

Nissan Skyline Alternators

Alternators are a pretty unsexy device. They hide somewhere in your engine compartment, lower right side of an RB26, and it just spins, and spins. What they do actually do is provide electricity at around 14 volts to your car.  Even though we call a cars system 12 volts, it is normally 13-14 volts running.   A car should never have to dip into the reserve capacity of the battery when it is running, however it might.

R32 GT-R Fuel Tank Leak

We have seen this once ourselves, but heard about it a few times from people.   There are a couple of vent lines on the fuel tank. On this car, it leaked fuel when filling up.  Once the tank was removed, it was pretty obvious what was wrong.  The R32 GT-R uses a plastic tank, the other Skylines use a metal tank.  They can rust, which we have also heard of, but have never seen.

There are several lines on the top of the tank that can perish and leak. When you have it down, make sure you replace all the ones you can see. Do it once, do it right.
