I'm sure that would be fine.

I use this when assembling engines:

[Mr R.]

Cheers, ill order some of that then.

On the nissan lumps i build every day we just use 5w30!

millers competition assembly lube if you MUST, or just engine oil

That's what I am using.

As above, I just oil liberally on assembly these days unless its something mega expensive where I want belt and braces, the lube isnt really required TBH in my experience.

Important to run cams in properly though.

^you just add a dash of sand no?

Flol. That would certainly run it in quick.

Couple of these should do the trick?

Chip, how do i run my cams in?

 

[Dan@SJM]

Start it up, hold it at 2000rpm for about 15 mins.

Cheers Dan.

Your cams aren't new though. Or are you getting new lifters?

I don't know weather to change them or not Tom.

There was i thinking my head was mint only to find out that it needs 16 valve guides. :dapprove:

Ill give Adam a call and get a price.

Secondhand cams don't need running in.

 

[Fred@BTM]

I've always wondered what metallurgy process can possibly happen with "running in cams" 2000rpm for 15min will do diddly squat to them, as will 50k miles (with decent oil changed regularly!)

I find lapping paste works well....

Its essentially to finish off the polishing of the lobes mate (and to match their wear pattern up with the lifters specifically), you can see a visible change in the shine of them after they have been run in IME

polishing on roller rockers though?

Yeah I get what you are saying there in the context of an F4R, Im sure that makes it far less critical, must confess I still always observe a run in anyway though on new cams. But I am sure its far less crucial than on other engines like a williams etc due to the roller rockers.
