Cylinder head; Cam follower proper installation procedure

Hello to all,
Starting a new Metro project and need some help. This project has been through a lot but I have a replacement
engine rebuilt and ready to go in. One Question I have is on the cam followers. I followed the book and submerged them in motor
oil when they came out but when I picked up the cylinder head at the machine shop the machinest told me I should gently put them
in a vise and compress all the oil out before installing them. This goes against what the manual says and do any of you have and opinion
on which is the correct way to procede. I have bought a new back flow check valve for the block so that will be good and there should
be plenty of oil supply up in the followers. I really do not want to bust a valve or what ever if I do it wrong. Any help would be really
helpfull. Thank's, GJ

I know what you mean. I've been confused about this point too. I guess it's time to get it clear once and for all.

There is a rebuild guide for the lifters here on the forum (how to section), plus a couple of good threads also. To my knowledge, only the Haynes goes with the "keep-submerged" method, while everything I've seen on the forum goes with "no-submerging-needed" method, although in reference to a rebuild/clean up.

Based on experiences seen here, and the ease of the process, I would suggest the rebuild/clean up method. I've seen no complaints about following the guidelines in the "how to section".

The rebuild guide is here: http://geometroforum.com/topic/3937058/1/ I let mine soak overnight, put them in and away I went with very minimal initial tapping, 30k miles later they are still going. I do definitely recommend cleaning them as part of the rebuild to help avoid future issues. When not full of oil they should compress smoothly and rebound under their own spring pressure.

If you haven't already seen this post you might find it interesting. http://geometroforum.com/topic/4591214/1/#new Good Luck!
