<br />
The water boxer is particularly nasty with big ends because you don't always hear that they've gone!<br />
<br />
I recently had a mate wanting me to do his head seals and I found a couple of rusted studs. This meant that I had to strpi the engine right down and found that 1 big end was badly worn (.15mm loose!). I made hiom come and see the engine before I carried on with it and he couldn't believe it because there had been no knocks or rattles.<br />
