Had the Fronty at the dealer to replace the two secondary timing chain tensioners (warranty) at 36,000 miles! They are almost completely eaten through by the secondary timing chains, a problem that Nissan Frontiers with the VQ40 engine have been having. It manifests itself as a siren like noise as the chains eats through the plastic and hits the metal underneath. Looking at the old part, it appears to my eye to be a nylon part but I cannot swear to that.
I have used only Mobil 1 in the engine and there was no visible varnish or color on any of the metal parts. But I am curious...does anyone here know of a relationship between oil type and this kind of sliding wear? I know from Frontier boards that all types of oil has been used where this failure is found so I don't think there is but I would likie to hear your thoughts, please.
Thanks in advance.
