This section is for those who have recently acquired an RD28.
Apart from a small list of inherent problems, the RD28 is an under-powered but capable and reliable engine.
The harmonic balancer keyway has been known to strip out. This is caused by incorrect torquing of the bolt or not checking that the bolt is torqued at regular intervals. The constant knock of the diesel at idle contributes to the problem.
The next thing that you must check, is that the timing belt has been changed out at the required service interval.
The top camshaft sprocket has been known to crack off.
Overheating problems have been reported and can result in a cracked head, so keeping the cooling system in peak condition is essential.

The manual gearbox fitted is the FS5R30A and is similar to the RB30 petrol version of the Patrol. (The TD42 and TB42 have the heavier and stronger FS5R50A)
It is very important to use the correct grade API 4GL gearbox oil, as the wrong grade can cause gear shifting problems when cold or hot.
Hard starting when hot is caused by wear in the injector pump or problems with the glow plugs. http://www.nissanpatrol.com.au/forum...ot-start-issue
If your RD28 is producing an excess of white, blue or black smoke, this thread may be of some help. http://www.nissanpatrol.com.au/forum...=diesels+smoke
If you need to drain the cooling system, make sure you remove the plug (socket needed should be 22mm) at the rear of the block, under the intake manifold. The plug uses a copper washer as a seal, and ideally, this should be replaced each time.
