Sealey Combustion Leak Tester - normy

I bought one these recently - Model VS 0061 - my daughter's E reg. Polo was loosing a bit of water.

The device consists of a conical rubber part which is held firmly on top of the expansion tank - making sure the engine is up to temperature - on top of that is a clear plastic chamber, above that is another chamber within which is poured a blue liquid (which turns yellow if there is exhaust gas present) and a rubber bulb is fitted on top.

The instructions say to wait until steam enters the bottom chamber, at which point to squeeze and release the bulb which draws the steam through the blue liquid in the upper chamber.

The trouble is steam never enters the bottom chamber! Sealey's sent a replacement but thats the same. I wonder if anyone has one of these testers and had any luck with it.

Sealey Combustion Leak Tester - injection doc

yep there very good, run it up hot then put it over header hole, good idea to get someone to rev car very hard a couple of times then sqeeze bulb, if it isn't cahnging colour its good news.
Dont forgat how dangerous the hot water can be & how it can shoot out when it reaches boiling point. Dont worry about the steam, if there are gasses in the water it will find them
