[QUOTE="astroboy, post: 410602, member: 4527"] Mileage? Service history? Engine shut down has nothing to do low engine compression. Why low engine compression? Do you suffer loss of engine oil before the shut down? How bad? U only overhaul engine when the damage too serious, piston crack, cylinder scratch/scared, con rod break, mostly due to flood damage. Low compression must have a cause, high mileage? >200k km? Where's the leak of compression? Through valve seals? Through header gasket? Through piston rings? Symptom: ~ Valve seal: white smoke exhaust emission. ~ Header gasket: oil on engine body around the header gasket area. ~ Piston ring: Wet spark plugs. All 3 also will experience engine oil level loss. What engine oil u using? 0w-30? 5w-40? 10w-40? 20w-50? The smaller the front 'W' number, the thinner the oil. If old engine, oil loss is expected too. Your problem can even be as simple as fuel pump, crank sensor, etc. What's your story? What is reported on GT1 diagnostic test? [/QUOTE]
