Need some advice please.
I’m assembling my A10 rocker box and noticed the rocker shafts have an oil channel running along its length. Can’t find any info on the orientation of this slot, when re-assembling. Help please?

I always mount them oil channel upwards.
The reason behind it is that the oil then comes out from above and thus doesn’t have to work it’s way up to lubricate the rockers.
That’s my theory anyway

He’s, that makes sense. I’m surprised that it’s not recorded in any Service Sheets or after market manuals. I’ll follow your advice, many thanks👍
