Well,
I pulled the plugs to see why the 250 had a miss.
I hoped to see the first three plugs to be one color
and the last three to be another. Not so lucky.
The first five plugs where a nice tan color, the
#6 plug covered in oil. Well, maybe the plug
fouled and quit firing and built up oil over time.
The compression test...
cold engine dry
90 150 170 140 160 and #6... Zero!
Wet (few squirts of oil in spark plug holes)
92 180 195 170 195 and #6... 7psi.
I figure that #1 has a leaky valve,
I took the valve cover off to check #6 to see if the
valves where closing. The stems are going up and down
as normal.
My next step is to pump compressed air into the #6 hole
and find it's escape, (water, oil, intake, gasket, or exhaust)
My plan was to drive the car for teh summer and start the
restoration this winter. I know that the head Has to come off,
and the rings are worn.
Could I be missing something here?
Can I just drive it for the summer?
What kind of leak causes zero to 7psi. compression?
