What do you mean by smashed?
Do you mean burnt out?

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.

If its run a big end it always seems to be number three that goes.
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.

Eek - Throw the engine away time if that has happened.
Poor twin sparks. They really do need looking after on the oil front.

Still least there's plenty about.

Opinion: would it be economical to do the big ends, valves, piston etc on an engine damaged like this assuming labour was free? What is the typical parts count and cost?

new engine probably much less time consuming and more economical than a rebuild..the problem is you don't really know what you are going to find when you get in there.

I suspect this has been starved of oil at some point in order for this to happen, so if it were me I wouldn't waste time on it..just my opinion though.

This is a very old thread, of course......which Heavend has revived....;) In UK it would certainly be cheaper to replace the engine complete with a second-hand unit - because they are easily available. Not sure if it is as easy in NZ.

I'm pretty good at keeping old things going! Used engines are not readily available here - most around have been run dry of oil or with snapped cam belts and been turned into parts donors. Working ones exist but they're pretty costly....like 800 quid. I'm interested in rebuilding the engine as a learning exercise but want to get it right first time and not spend a million dollars on parts.
I haven't bought the car yet, hoping to pick it up cheaply. If not this whole subject is moot.

I'm hoping someone can pass on their experience and provide a guide of which parts are best typically replaced.

A friend bought one for his 156 for NZ$750. From Italian Autos in Auckland. Good running engine with 80 odd km on it I think. You need to add the cost of doing the cambelt before fitting.

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:

Piston rings
Big end bearings
Main bearings
Thrust washers
Cam belt kit (cam belt, tensioner & idler pulley)
Variator
Water pump
Head gasket set (inc valve stem oil seals)
Bottom end gasket set
Rear main oil seal
Spark plugs
Oil filter

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.

I seemed to recall I paid around £2500 for a full rebuild after the Crank let go.
