Every time the radiator cap is removed/refitted, the top Tank/extension is placed under stress. Removal of this stress is a plus as is the reduction of the concentration of the cooling fluid caused by the top ups. Brian

HI. I know this is an old thread but would like to add a comment. I have had some experience with the design and operation of modern cooling systems. I'm no expert but have enough knowledge to be a little dangerous. The early "overflow" bottles are in fact recovery bottles. They were introduced to reduce the need to remove the rad cap to check the coolant level and retain the concentration of coolant additives ( antifreeze and corrosion protection). They require a recovery cap to work. These are caps with a top seal to prevent the coolant from spilling past the cap was engine heats

I turned up an aluminum elbow with an O ring to fit inside the block. It has a small flange on the outer surface against the block. I then taped a small (3mm) thread next to the block breather hole and after fitting the new elbow screwed in a short screw with a washer that worked with the flange to prevent the elbow coming out. The elbow was then secure but could be turned to any direction required. This has been in place for about 12 years now. I did this with the engine out so would be a bit hard with it installed. It may be a bit to understand exactly what I done from this description

My betting is on the raised lip on the scuttle. I use a strip of small edge trim on the lip about 2 feet long to quieten mine. Brian

A quick addition to the above. You do not need the gearbox to be removed to fix the starter mounting nut, just the transmission tunnel. Brian

I have had to repair a few of these, two for myself and a few for other members and one Toyota. I have found two problems. Burnt contacts and broken wires where the coil windings are soldered the plate that connects them to the solenoid contacts. The broken wires can be first by soldering them back on. The contacts can be replaced as noted in the previous post. Burnt contacts are the most common. I have found the the contact kit that includes the armature is the best,\. The armature is the part that is sometimes called the plunger. It is important that the contacts remain flat in th
