Looking at various threads and Pug manual it says to coat the threads and under the head of the bolts with Molykote g rapid grease. I presume this is to get a true reading of the torque value. as this is harder to get hold of than rocking horse crap, I was hoping someone could suggest an alternative. ________________________________________ chris |

indeed that is the reasoning, most sets come with a sachet of grease for this purpose, otherwise any moly grease will do.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

used sparingly mind you, as the head bolt threads in the iron XU block are blind, i.e closed at the bottom.excess grease can cause a seal and hydraulic pressure under the bolt, giving a false torque reading in worst case scenario. I dont think it's likely to happen in an XU as theyre quite sturdy, but it has been known for hydraulic pressure under a headbolt to crack a cylinder block. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |
