Setting rocker preload

[caduceus]

Anyone done this before? Do you have any tips for the uninitiated? I know it needs to be between 20 & 60 thou, but that's it.

Cheers

Mac, YHM.

Thanks for that Steve. Appreciate the write up

I suppose I'd better take those spark plugs out that I've put in... :|

The followers are new and have no oil. But that was one of my queries. Now answered. Thanks.

So I followed the great write up above today, and yes, I do need shims! The 60 thou tool/coat hanger giggled about in there like a chipolata in a Kings Cross gash
I reckon it must be between 70 & 90 thou easily. So will be ordering some shims first thing Monday morning. Might make a 100 thou tool tomorrow and see how close it is.

When you are finally happy, fill your followers with oil through the small side hole until oil oozes out of them. Saves a load of clatter on initial start up.

Thanks for that Carsy. In the interest of learning something new, could you explain what the reason/benefit of doing it this way is please? Something to do with the firing order? Or just convenience/efficiency so I don't have to turn it over for each cylinder?

Where did you get your shims Caduceus? I am in the process of doing mine, so this was a handy thread of information for me

Will be getting them from Real Steel.

Just minimises turning the engine.

Have a look at V8 Developments website. There is a useful and easy to follow procedure for setting preloads in their Technical Section under "Valve Train". They also supply shims. Found them really helpful.

I've had a look at the guide V8 give, and it differs from the method Steve wrote above. Does it matter which method I use? Will it have any adverse effect on the engine?

Thanks for all the replies gents. Got the shims today and had a final measure before fitting 32 thou shims. They are roughly 50 thou now, with some of the exhaust ones being more like 30 thou.
I'll be glad to finally get it back together and looking like an engine again.
