Lets help Apolan get new/fix old 4A-G

[Dogs Danglies]

TBH it doesn't sound promising that the bearings are gone, and also the gauge is showing no oil pressure. Danger is if its from lack of oil pressure the crank is probably screwed, and possibly the con rods too. You might be lucky and maybe it is just a broken gauge, but then again maybe not. Are they no 'backstreet' garages near you, 4age is a basic engine by modern day stuff, any competent mechanic, could take the head off, take the sump off and inspect the damage, and give you an idea if its worth rebuilding, or replacing.

Good luck anyhow, may be its time to look into getting some nice shiney bits to go inside the engine
