About a month ago and at 257,000 miles my timing chain tensioner shoes finally gave way and really got very loud. I drove about 15 miles home and parked it. Called dealer and they gave me an estimate for a complete chain kit replacement so I said ok. Drove the car there another 15 miles being afraid it might explode but I made it. Since it was there I also thought it would be a good time to have the valve cover gaskets replaced on both sides since they had been leaking for a long time. While all this is going on I get a phone call from the dealer and the advisor tells me that while the tech was removing the cam sprockets to install new ones they noticed one camshaft broken and only being held by the center bolt, also a secondary cam had a crack on it. I was like WHAT!! How’s that even being possible? Maybe they did it? ... Tech said this pathy was the worst condition one he had ever seen a timing chain be in; shoes completely worn, evidence of chain slapping and could not believe how the car was even still running with broken and cracked cams, lol. So now all four cams need to be replaced since Nissan only sells as a set......Bummer!
A month goes by and they call saying its ready …I am not pleased this job took so long!
This is all they replaced:
-Complete timing chain kit
-Water pump
-Thermostat
-All four cams
-Valve cover gaskets
-serpentine belt
So now the Pathy is running again and hopely ready for another quarter million miles, lol. I do have to go back for the idler pulley and clutch fan bracket replacement since that was my agreement with the advisor and they did not change them. And now for the shocker bill ,a whopping $3,500 …….guess I’m going to keep her a while longer and fix the small things and do some maintaince items I need to do like replace the diff oil which I have never done . Truck is been with me since new.
