hi all,

I am in the middle of replacing my intercooler & found number2 glowplug & the rail it is bolted to at the top all corroded, for the life of me I cannot understand why or how this could happen, I am having trouble starting it, I cleaned the MAF & it was noticably better but still not good, I have ordered a new rail for $45 from Nissan & will replace the corroded glowplug, is this common?, is there a reason for it?, has anyone experienced this issue?, I was told by one person that the air escaping the leaking intercooler may have caused this but I was dubious as it would have thought some oil contaminate would be in the leaking air, having said that one of the leaks was directly above this plug

regards

Morton
