as previously said.. "some people will argue, but I've seen too many TS engines suffer big-end failure within 2-3K miles after a belt failure, as the pistons hitting the valves puts heavy shock loads on the big ends. Not wishing to be alarmist, just sharing my experience."
Be careful. The 156 2.0TS I rescued had big end failure less than 2000 miles after a top end rebuild (head skim, valves etc.). Once the big end bearings have gone you really need a replacement engine - much better to get them done at the same time as working on the top end - imho. I changed my variator as a precaution (in for a penny in for a pound) - you're welcome to it. You can buy a new seal kit off Flea Bay for it and recondition it on your dining room table I think? LOL
