That's very helpful mark. It seems I need to pour water down and check it but by the look of it, a lot of cars have the top hat missing completely. It's possible that I couldn't see the bend on the one on the passenger side as it's heading towards the side of the car and that's the angle I was looking at it meaning the pipe was actually running back towards me. I'll see if I can fish it out or make a long pair of pliers to reach in. Not overly worried as the cars inside and really won't do much until I'm in better shape next year.
On the plus side, I was checking my history. It has only been serviced in August so I don't need to panic on that 1 but it was only a minor/annual service so I'm assuming oil and filter only. It has a reasonably fresh paper filter so I'll get plugs and a fuel filter for peace of mind. I'll maybe stick in a piper x filter here to and do the airbox mod. Probably never hear it as I have full stainless headers, cats and rear boxes already. I was given 2 standard rear boxes with the car but I'll probably sell those on as I don't think I'll ever use them.
Another thing to note is I have a ticking from cold. Lasts maybe a minute on idle. Gone after that and I'm assuming it's just a sticky tapet.
