he guys,
im going to be chaning the lifters and rockers on my corsa 1.4 sri, and in the haynes manual it says that when you replace or renew the lifters, to lubricat or cover the contacting surface with molybdenum disulfide paste. now i work in ag machinery repairs and i have only ever heard of molybdenum disulfide grease.

all i want to know is whats the differance and can i use grease instead of paste? Or can i get away with using anything else or nothing at all?

regards

Grease is fine.

Some people just slap some oil on them

Thats brilliant mate cheers, another quick question? What does it do and how much should i put on?

thin smear, like butter on toast.

It prevents the parts from grinding each other to bits before the engine gets oil circulated through it, but as Taurus said, smearing some oil on is also fine.

The moly grease on metal-to-metal parts is more important when a brand new engine gets fired up for the first time at the factory. With oil in the pan and nowhere else, some parts of the engine might not get full oil pressure for 10 seconds of idling, hence the grease to protect it until then.

Sorry to hijack.

But since my car was /sometimes still sounds a bit louder for a short time during start. Would it be worth me doing this?

This refers to an engine during rebuild, not normal starting. Best start a separate thread if you've got a concern about noises during first starting.
