I want to run on 7 cylinders with one cylinder with the spark plug out.
My 200k mile 4.0l P38 has a block crack on a rear pot that blows the water out when warmed up. Had a new head as the old one showed up a crack on test but I still get too much coolant pressure. I don't want to spend £2,500 on a new block for a car worth £1500.
The idea is to put a modified spark plug in with a silencer (bit of pipe, tin, wire wool) and to pinch the lpg feed. It runs fine but noisily with no spark plug. There is now no pressure to blow water out or suck it in- the K-Seal might even have a chance to work.
The questions are - has anyone run like this for any time? What might go wrong - perhaps anti knock sensor alarm, Lambda sensor problems, crank imbalance, explosive gases into the engine bay?
