note #1 on the exhaust cam and #2 on the intake cam (between cyl 2 and 3)... Since these are the same cam - both 272 ~ 9.0, the fact that they carry sequential numbers is a blessing for me... Why?? because it is now that I have to choose which cam goes where so that I can determine the final clearances....





and to determine the final buckets.... yep I said buckets.



My client is going the 1SZ one piece bucket route and it is up to me to determine the CORRECT bucket for each valve/lobe combination. The buckets above are the thinnest available - 5.12mm

First I check the clearances for the exhaust side...





I then swap the 8 sizing buckets and then I check the intake side....



I can be one of those crazy people who likes things as exact as I can make them.... sometimes, when you are checking valve clearances you sometimes wish you had the capability to measure down to .0005".



This is important when I'm purchasing 16 buckets and they are $12 each, I'd rather not get this wrong....

Ok.... since I don't want to get this wrong.......

how about a bit of a brain teaser...


the photo above is an intake cam lobe. Tell me what 1SZ bucket I'll need (10 digit part number, please)???
