I know I'm very likely to hear people telling me to avoid using either of these products, but in the situation I'm in I really have nowhere else to go.
The engine in question is a TDI 1.4 (75) and thanks to the help of some good people on this forum the diagnosis is that I have a pinhole in the head gasket or a tiny crack in the block.
The problem is not yet severe. I can drive all day at 50mph with no problem apart from loss of coolant. The engine only overheats when I hit 60mph. There is no emulsion in the oil, nor any sign of any leaks. Can't see any steam from the exhaust either but I'm losing coolant at the rate of half a litre per 100 miles.
The thing is, as much as I love the car, cosmetically it's as rough as old boots and just not worth the heavy cost of a head repair. My plan therefore is to keep the engine going as long as possible. When it finally gives up on me I'll be looking for another A2.
In the meantime I suppose some sort of head sealant is my best option and I was wondering if anyone on here has experience of this type of product with the TDI engine.
K-Seal is certainly the easier option as it will mix freely with antifreeze/coolant and therefore does not require flushing out the cooling system before use.
Wondarweld can only be mixed with water which means the cooling system has to be flushed through twice (before and after application).
K-Seal is cheaper too so would be my preferred option unless I hear from someone with experience that Wondarweld is a markedly better product.
I know it's a shame that I find myself in this predicament but them's the breaks! Wish me luck.
