The pushrods will be straight as the engine has just had new cams fitted so everything will have been checked.
Looking at the installation instructions for the standard pressed steel rockers they give a tolerance for the amount the hydraulic lifters are compressed when tightening the mounting bolt, relies on the lifters to take up any manufacturing tolerance unlike the roller rockers which can be adjusted precisely with the adjusters on the rockers.
Whether this is an issue or not I have no idea, probably not!
Thought I’d have a look at the engine running without the rocker covers in place, from cold start at tick over it takes an unbelievable amount of time for the oil to reach the rockers.
Number one first quickly followed by two and three and then some while for four,
I actually thought blimey fours got a blocked oil way it took so long but when it did come trough looked the same flow as the rest.
So from cold don’t rev the engine much for a couple of minutes as there’s no oil in the valves!
