Valve adjustment of buckets

Sorry for the long post, hope it makes sense and is easy to read.

So I have been reviewing a 1.8L Zetec head assembly process ,I have the 2.0L but there is a lot if info posted on the 1.8L. Looking at the head assembly procedure to make sure I understand what all I need to do once I get my head worked on and what all I can do my self vs. asking the shop to do. I have also spent the last 3-4 hours searching this site and others about the process and what needs to be done. but still have some questions.

I am looking at my "buckets" (though images I have taken) and I don't see any way to adjust the bucket to increase or decrease the "valve lash" or cam clearance adjustments. It looks like you have to get different buckets to accommodate each valve. I have labeled them and will measure there roundness today, but if once installed they don’t fit the adjustment do you have to get new ones?

I am guessing once you have a valve job done (due to the grinding) the valve will typically be “longer” so you will need a thinner bucket? Is there a “stock” bucket size so I know what I am starting with before I measure? To measure the bucket thickness you measure just the distance between the top surface where the cam lobe presses and the inside surface where the top of the valve stem pushes right? so you need a micrometer to be able to measure that…

Doing valve train work is all new to me so would appreciate any help you can provide. It looks like its rather simple once you have the buckets, just time consuming if you get it wrong and have to order new ones remove the cams, install, and repeat and so forth.

It looks like buckets cost $18 - $23 each depending on size? That’s crazy, if I need 16 new buckets that’s $288 assuming minimal costs. Are you able to get them for cheaper some where else? I was looking on fordparts.com but sounds like you should be able to mix and match between the buckets where you might only need a few?

How common is it to need new buckets after a valve job? I am using stock cams, with upgraded crower springs and retainers. I am trying to brace my self for sticker shock.

Thanks!

The buckets have no adjustment and there is no " standard " bucket to start from

If you let your machine shop do it then they can cut the seats first then before they cut the valve tips have them mock up and use the valve length to adjust your valve lash this will in the long run be cheaper then buying buckets and if you think about it , your buckets fit now , if they cut the seats and the valves to do a valve job then that moves the stems up further so they need to be cut , using this step to adjust the valve lash is perfect and keeps you from buying buckets

So I will make sure that's clear when I drop it off. I just need to have a good discussion with the machine shop and make sure they do most of it then. Sounds like that will be the cheapest and most professionally done in the end

You can swap buckets around too if the surface still looks good, I always polish them up a bit with 600 sandpaper to clarify the wear pattern.

As he says you can cut valve tops as well, just make sure the tappet does not contact valve locks at all. I got one running with valves cut now at like 90,000 miles after doing it and still running fine.

Your measurement idea is correct.

No one size stock bucket, they will mostly be grouped around a very few sizes that most new engines need but I've never heard what that range is. No matter, you need pretty much closely set anyway.

Set to the middle of the clearance range, if you set up a little tight like you would other engines, the exhausts close up clearance from recession and then no valve seal and engine goes to crap. Maybe a little tighter on intakes, they commonly only polish seats unless you have stronger springs, then they may wear more. Normally intake seats can simply be lapped in and no need for seat grinding at all unless really high mileage. So in your case maybe no need to grind intakes. The exhausts will usually need it, but you'll get closer if you specify the grinder guy cut valve tips to match what was removed from valves and seats. Think they use one half the amount for 45 degree seat angle. .030" at 45 degree angle=.015" in direct length change.

A low tension set of checking springs like used for race car are really helpful here. I've set up valve clearances on the kitchen table before using them, you can easily pop retainer off and on by hand with no tools needed at all. How I do all my motorcycle heads too. Put a valve assembly together and then push valve wide open and let it snap shut to set all parts solid and check clearance with cam in place, not all caps on, but make sure what you do use is the side clearance cap, one nearest sprocket on these I think. Caps snugged down but no need to pull all the way up to full torque, they strip out easy enough as is.
