Hello all, my name is Baz I live in NZ I have a r50 diesel terrano. I am a heavy plant operator and have been around diesels my whole life.
I bought my first Nissan diesel in 2008 wd21 with the TD27 for $2.5k it had done 225k klms and it would have a lot of trouble starting!
I soon found air was getting in to the pump while sitting overnight, so a non return valve and new clamps on the filter to pump line fixed that.
I thought the tappets sounded a bit loose and seeing as all the nissan diesel manuals Ive ever looked at, under maintenance the first thing it always reads is set your valves, So i adjust the valves up and start her up and all hell and high water broke loose what a noise!
I soon found out a common problem with this series diesel was the rocker pads wear out. sorted it and with a full service including auto away she went. Wow what a great wagon sit on high revs all day long and never miss a beat. Over the next few years I did a snorkel new suspension a 2000watt inverter and new tires. I to this day regret selling that wagon a good solid truck.
At work they had a r50 with a QD32 and I would often drive this wagon to and from different sites it had done nearly 500k and I thought cool these things must go for ever, plenty of power, I like these wagons. So I did more study on the R50 diesels including looking at our local classifieds Trademe and punching in vehicles with the highest KLMs and low and behold it comes back with an R50 3.2 diesel with 860k man that says a lot, thats good, well so I thought. Over the next few month's I made the decision to buy.
Finally finding one up north with 160k on it, one owner in japan and one owner here. He was an old guy who used it to tow his caravan around a couple of times a year $6k.
It had been well serviced with an extra oil cooler added for auto.
I drove back down south and it went like a dream. However it had a strange puffing sound coming from the engine it turned out to be a rip in the big rubber intake hose or boot. It also looked as if the fuel pump had been off due to different colored paint on some off the main bolts. I had read of problems with the epumps in the past so assumed this was a good thing, something about leeching seals.
I have had this wagon for three years now and it has always had a slight stating problem and cold mornings below zero I would sometimes have to glow it twice and then a big puff of black unburnt diesel. The glow system has always to me seemed a bit short the light only staying on for about three seconds at a time. A couple of months ago i bought some new glow plus Techno from Aussie they seemed different from the ones that came out but were the same length and the thread went into the head the same distance so I thought all good. But no! Now the engine takes three of four glows and puffs out even more black smoke and this on a warm day.
Im joining this site to search for answers. Any points in the right direction much appreciated. Thanks for reading B
