At the present time my son-inlaw and myself are installing a new cam . timing chain, cogs and lifters, and heads, on a Rover 3.5 the heads have been skimmd, i keep coming across information on setting lifter pre-load, iv'e spoken to engine builders ,some have never even heard of this, others say forget it just drop the lifters in after filling with oil and put it all toghter, now my question?
have any of you guys set your Pre-load and whats the easy way, and if you guys have put lifters in without pre-load being set have you had any problems. o yes i'm also using composite head gaskets.
