List,
About one month ago I mailed the list about the trouble I have with the 1800
GT engine.
The problem was that it the engine made a noise like it was pingin heavily,
when increasing RPM.
I first thought it was the big end bearings, so I replaced these and also
the oil pump, since the rotors did not look to good to me. But...... still
having troubles. Pinging sound.
What I have determined so far:
I have some underpreasure in the engine. When I remove the oil filler cap, I
can feel the under preasure and as soon as I remove the cap, the engine
starts running faster, say from 700 to 1200 rpm.
The engine shakes heavily when idling.
When removing the # 3 and 4 spark plug cap, nothing happens. The engine runs
like before removing them.
-when removing either #1 or #2, the engine dies-
I checked the # 3+4 carb, all looks OK. Including the floatlevel. It has
fuel in it.
When removing the #3 or #4 sparkplug, I can feel the compression, but not
smell any fuel.
Question:
Where can I look next? Where does the underpreasure come from?
Thanks in advance. Rene
