Default Help with Cam Buckets

I am being told i need a size for the cam buckets on my shimless 2003 wrx set up. I need to order the thinnest possible in order to check and set valve lash and order new buckets where needed. Subarugenuineparts is telling me they are very very size specific which i understand the thickness is very precise but is there any other measurement? I told them i need the thinnest bucket possible, i can measure the gap and order or reuse my old buckets from there.

Does this sound correct?

Thanks all.

You may be overthinking this a bit. You need new buckets for what reason? If your lash is out of spec, you want to make a chart of the clearances you have now and note what the difference is to the correct clearance. Measure the bucket of each valve and apply the difference that you measured for that valve.

Once you have those measurements, order the appropriate buckets.

Hopefully I'm uderstanding what you're asking correctly. The buckets will have the same OD measurement, so the thickness is the only critical area to worry about.

Its better to have buckets that are too big than too small. that way you can always take some off of the valve stem to make you old buckets work.

Typically you'll have some buckets that will work. Just put one in that fits (Don't assume it has to be the smallest but it might end up that way), measure the clearance, note the bucket size (marked on the underside) and add or subtract from that number to get the clearance you need. Take a look through your buckets and see if you have a bucket that will work. Typically when we build a motor we often have to swap 4-8 buckets and usually have to order 2-4 for the customer if we don't have them available to swap out.

Thanks,
Phil

Very sorry for the confusion, i will be regrinding and reseating the valves and heads. I will be reusing buckets where applicable but i need to get a base measurement.

Or i can just start with one old bucket and keep trying until i find one of the old buckets that give the correct clearance. I just figured with 4 new buckets that are the thinnest possible, i could get a base measurement and mic the old buckets after i find the difference needed and use them where they are needed and order new buckets where i do not have extra old buckets that work.

Thanks again everyone!
