So... a pattern seems to be emerging regarding engine failures with GTB powered Fabia's. Mine having blown last month, Adam's last week, Kev's some time before, Silky's on another occasion etc... Failures are tending to be knackered bottom ends, i.e. pistons melting or cracking.
A small group of us (including John, a.k.a. Faboka) have been discussing what the possible cause of these failures is down to. There's been suggestions such as injector failure, cyclic heat stresses, excessive cylinder pressures, stock injectors etc... However, we're yet to come to a conclusion. Obviously we don't have VW's R&D resources to play with here!
My engine should be being opened up in the next couple of days to find out what has gone. Although it's likely to be a cracked piston. Southy has had his apart today and has also found a cracked piston. I'm sure he'll be along soon.
Now obviously these cars are being pushed to twice their standard power with some serious boost pressure. Does anyone have thoughts from proper educated knowledge on what would be causing these types of failures? My worry is that there are more and more GTB powered Fabia's appearing, and seemingly there's many ticking time bombs out there waiting to go off - ours being some of the earlier cars that have now run more mileage. Not to mention our worries of rebuilding them to have the same happen again later down the line.
