If I had hair I would be pulling it out.
I cannot seem to get the settings right on my new 235.
There is still something going on with the head. Still looks like something is leaking out of the gasket line. Something that looks like oil.air as it is in tiny bubbles
I pulled the manifold today to check for vacuum leaks since I can only get about 16 out of it and it surges at high rpms unless I advance the timing about 10 degrees.
I readjusted the valves (again) after normalizing and low and behold I got 21 lbs of vacuum at 500 rpm. I set the timing at top dead center and managed to have the vacuum (19lbs), timing(TDC) and idle (500 rpms)all where I wanted them.
Went for a ride and the surging was back. Checked the vacuum and it was back to about 16.
If the head gasket was defective could that cause a vacuum leak?
I can hear a puffing noise in the manifold when I rev up and release the throttle. When I reseated the manifold and that did not help I assumed it was due to valve adjustment.
Last time I adjusted the valves the puffing stopped and the vacuum was 21. But that did not last.
If I set the timing advance so that I get 18-19 lbs of vacuum runs pretty good and has power but not much more than my 60 year old 216.
Anyone got any ideas?
