ok...I have placed a new mark on the flywheel where TDC is according to the piston and valve position. It is about 10 degrees after the ball bearing. about 1/2 inch past the "C" marking. I now have a reference for TDC when timing.
I did a compression test and I got 110 from each cylinder except for #4. That one only has 90. (results were the same wet or dry for each cylinder...#4 still only had 90)
The spec for this motor is 130 minumum which may be the result of the newness of it. It could increase over the next 1000 miles as it breaks in.
I am concerned about the #4 cylinder as I remember the exhuast valve on that cylinder was tougher than the rest to remove. I thought it might be bent and did point that out to the shop when I brought it in for the rebuild. I will do a leak down test later this week.
Does anyone think I am being too fussy. Should I run the motor and check compression in a few hundred miles? Could this resolve over time as it breaks in? I hate the thought of a valve job on a new motor but I do have a warantee.
I would guess I am as sick of these problems as the machine shop is of me at this point. however I did pay them a lot of money to quote them..."do everything to make the engine run right".
