We took Beryl down to Sidmouth at the weekend. Lovely day, and free parking in East Devon District Council's "Parkland" head office car park.
Anyway, Sally drove home, and I had a chance to take in the sights, sounds and smells from the passenger seat.
There was a ticking noise coming from the engine cover area which varied with engine load, together with a slight exhausty/dieselly smell, so once back in the workshop, this had to be investigated. We can't have fumes in the cab!
The exhaust downpipe wasn't accurately lined up with the manifold, and soot marks were evidence of a leak. There was also a small gap between the hatch cover rubber seals, due to the edges of the steel not lining up properly. Hence the ticking noise.
The old sealing ring didn't seem to be the right sort either. The new one I got from Martin was solid steel, but the old one was sort of composite, and looked like this................
So I slackened off all the brackets and joints in the system, and realigned the pipes, with a new joint ring to the manifold.
Should have done it right first time, shouldn't I!
Ok, no ticking noise now, but the whole area was covered in diesel AGAIN. Henc the dieselly smell.
Two more slight leaks found. One joint on a back leakage pipe and one from one of the injection pump connections. The first was easy enough, (just stole a bit of pipe off the spare truck engine), but it took a good half day to strip and seal the connection, as it was behind a load of injection pipes. I hate breaking open diesel pipe joints, as there will always be one that doesn't seal again when you put them back.

Hardly surprising because the pressure is around 15000 PSI in there.
Anyway, hopefully they are sealed again now, and hopefully this will be the final batch of leaks to sort.
It's gradually getting drier. The drip tray doesn't have any oil in it since I did the engine, and maybe even no diesel from now on. I'm not betting on it staying dry though.
