My 147 2.0 TS engine stopped with grinding noise got towed home checked timing which I renewed 2000 miles ago thats ok took plugs in No3 cylinder both plugs are smashed and engine seems to have seized has anyone got any ideas
Oh dear, thats not good. Will either be a dropped valve thats been mangled against the plugs or a conrod or piston let go. Almost certainly terminal for that engine. A compression check should confirm.Keith
It is usually, and if the bearing has completely disintegrated there is enough movement of the rod on the crank journal that the piston can tap the head, maybe that is what has done in the spark plugs.If its run a big end it always seems to be number three that goes.
These are the "consumables" that you'll need to replace, but you'll also need to carefully check anything you intend to re-use like the cylinder head, valves, pistons, rods, crank, cams etc:I'm hoping someone can pass on their experience and provide a guide of which parts are best typically replaced.
Might as well add Clutch and slave cylinder to that whilst the engine is out. When my Twin Spark let go I did everything. No point in putting old consumables back in when you are spending so much.These are the "consumables" that you'll need to replace, but you'll also need to carefully check anything you intend to re-use like the cylinder head, valves, pistons, rods, crank, cams etc:
Big end bearings
Cam belt kit (cam belt, tensioner & idler pulley)
Head gasket set (inc valve stem oil seals)
Bottom end gasket set
Rear main oil seal
