Alright everyone... I'm a complete hack-shade-tree-mechanic, and I am aware. I want to bounce some ideas off all of you like minded folks... lets start with my basic knowledge and habits... I've got an 81 K-jet Saab that I put an 84 kjet saab turbo motor into.. I've had 4 240's-- a 90, an 85, and currently own a 81 242 and a 91 240 that I gave to my grandfather. Here's what I'm planning to do with his 1990 740 16 Valve this weekend:

Long story short, my mother lives with my grandfather and doesn't really work for a living... she dumpster dives and scraps her finds for cash using the 90' 740 16 valve wagon, she murders cars... MURDERS them. There was chocolate pudding in the crank case so old pawpaw and me pulled the head last weekend, We ordered a gasket kit, and he dropped the head off for resurfacing and a valve job... we cylinder number 1 has a crack where the spark plug goes I'm told. we tried to source a head, they are rare and expensive, the car is ragged out I mapped out the idea of swapping to an 8 valve head... EXPENSIVE.... looked at doing a motor swap... cheaper, but time consuming and mama's gonna destroy the car in the long run... almost picked up a 940 turbo wagon for 1200 but again... kinda broke right now.

My genius idea... DEACTIVATE CYLINDER 4

Butter up cylinder number 4's spark plug hole with a crap TON of jb weld, reinsert dead spark plug

Remove the lifters for cylinder number 4, cap off the wire hole on the distributor cap for cylinder number 4 and leave a dead spark plug in cylinder number 4, leave the injector unplugged for cylinder number 4. new head gasket, valve cover gasket, intake gasket, exhaust gasket, 10-30 oil with some lucas, 3 new spark plugs... should I keep the valves open for this dead cylinder? keep just the exhaust valves open? any feedback is appreciated in my white trash endeavor. THANKS!
