    Rubber over the spring is not that big a deal for a while, eventually the spring can break though, the rubber is a vibration damper to keep spring from rattling to break. More important is flexing the tensioner and watching for fine cracking in the rubber there, it comes off in pieces and the actual steel parts then break tensioner as there is not much steel under the rubber in places.

    Hello! Posting after quite some time. After a lot of hard work and patience I have managed to take the cylinders off. It felt really good to be taking the cylinders off but to my dismay, the connecting rods are in really bad shape. They are rusted an unexpected amount. I think I will have to opt for a complete rebuild but just wanted to run this through you so that I do not overlook any thing here. I am not that knowledgeable when it comes to con-rods and replacing them, so advice will be much appreciated.

    That's what they look like:

    Engine comes apart to fix it. The rods get glassbeaded then you look at the clean part for pitting holes that later will snap the rod in half.
