Default Valve lash just got more expensive

I went down to the Subaru dealership today and bought the last couple of buckets for my engine, I felt pretty irritated about having to spend 24.00 ea for mine and then the parts guy made me feel alot better about my situation he showed me the new valve lash caps they are literally the size of my pinky finger nail and they are 40.00 each

Are you bench setting lash or doing it on an engine that the heads have already been put on?

I put the heads on and torqued everything down, I was going to just do it on the bench but I heard there was a difference, I had originally started doing it on the bench then I went and installed them on the engine and rechecked the valves I already measured and it turns out there was about .001 difference between in stalled and uninstalled heads

Timing belt install will shift your clearances as well. At least, it did mine.

Also, FYI:

Maybe I should make a thread for this here on NASIOC too.

Thanks for that link that is definitely good to have, do you think that you may of had excessive camshaft journal clearance to cause valve lash to change? I mean that would really ****ing suck to have to install the timing belt to get the clearance right, it would be nice if someone else could give some insight on that.....

Well, at least for the LGT, the factory service manual states that clearances should be checked with the belt installed. I only thought to check after seeing another user on legacygt.com report a shift when they measured theirs out.

My approach was to set my bench clearances 2-3 sizes looser than nominal, to end up with nominal clearances when torqued and belt installed. Worked pretty well, except for one intake valve which ended up one size under nominal.

I also can't stress enough the need to have a micrometer on hand to measure out actual bucket thicknesses. I haven't encountered a single bucket from a motor with more than 50k on it that measured the same as the size it was marked. Worst one I saw was 6 sizes under the marked value.
