Cylinderhead studs

[JeanClaude]

I am sorry to ask a question which has been treated before, but I think that I read somewhere that the cylinderhead studs should be left in oil overnight before the fitting of the head. <br>
Is that right and what is the reason for doing it.<br>
<br>
Thanks for your help.<br>

Yes, I think it is from the Triumptune/Moss Book. I think it was only relevant to later spec studs. A strange one cos I wouldn't have thought the studs were very oil absorbant, but guess there must have been a reason <!--EZCODE EMOTICON START :rolleyes --><img src=http://www.ezboard.com/intl/aenglish/im ... s/eyes.gif ALT=":rolleyes"><!--EZCODE EMOTICON END--> .

to coat them liberally with coper ease or some similar copper based grease all along the length before fitting them...<br>

Go with Jonners. You do not want any oil on the stud as it will carbonise with the heat and then be a bugger to get out in the future.

Never got that idea, it is also in vintage car manuals, metal is not porous so whats the benefit.<br>
I always copper slip, its perfect for not sticking

Thanks for your opinions. As I use copper grease on nearly every bolt during the rebuild I will also coat the studs in copper grease so that they will not rust in the future. 4 of the 5 studs on my engine are so rusty that I ordered new ones ....
