I am trying to replace an inlet valve spring in situ. Does anyone know if there are special tools for this job, or has anyone had success with tools generally available. I have borrowed a tool, and have noticed that a stud is preventing full compression when tried in my first choice of direction and looking at the other springs, could be difficult with adjacent valvegear obstructing progress. I expect one of those impressive Lancia workshop wall racks containing special tools has something for these 'little jobs'. One tool I had in mind was the one which grips the base end of the spring and compresses the top. Looks simple enough! In the meantime I am using the tool pictured, which doesn't compress sufficiently to fit the collets. The valve seems to be closed and exposing the same length of stem as another closed valve. Hopefully the spring coils touching are not the limiting factor, so I will try a used spring from my spare engine and also see if I can measure compressed lengths in a vice. Free length matches spec in the service manual, which also mentions inner valve springs. I have one engine with, and one without inner valve springs. Can anyone confirm if some engines had double springs or if some had single, perhaps stronger springs? (I have used a handy magnet to pull the stem up)

I have heard feeding string into the plug hole and bringing the piston up to tdc keeping the valve in position…..

That sounds like a good idea lancialulu, compressed air seems popular as well. It does feel like the valve is coming to a positive 'stop', and rotates freely, without any noticable lengthwise movement. So hopefully fully seated and not bent. Also the temporary silver soldered threaded addition is a 'belt and braces', incase of something 'pinging off'. I have also covered any holes/ oilways with rag incase anything 'pinging off', achieves a 'hole in one'. That telescopic magnet does have limits when fishing out small parts, but has saved the day previously. Richard
