Pushrod Problems?
I still have the original rockers they look the same.
I can post a picture when I get home.
These pushrods have a ball and cup.
Did the 170 pushrods have a ball and cup?
We are in Indiana,explains a lot I know.
Thanks
Just wanted to know if you were anywhere near someone (maybe me) versed in slant sixes.
170 pushrods are ball and cup, but there is no way they could work on a 198/225 engine.
You said the original rocker setup, had the same issue (adjusters way down in)?
Do you know if any valve work has been done to the head?
There are only a few things that could cause the problem you have.
1) wrong push rods (possible, but not the 170 units)
2) Cam base circle too small (again possible, but not likely to cause that big an error)
3) Incorrect valve stem heights, due to incorrect valve job. (very possible)
4) Rocker shaft/arms not in the correct height in relation to the cam (usually problem is in the other direction, due to head milling)
5) since the rockers were rebuilt possible problem there (in your case not likely, as you stated problem also with original rockers.
I'm leaning toward number 1, or 3
