Some help required. Lots of niggling faults,

It pays to be attentive to these machines.

Today, a visual inspection showed me there was what appeared to be oil covering the right side of the manifold. It was clean last time I looked. Its caked in black now and what looked like fresh oil. The fuel line grommet at the back of the engine bay had popped out letting the fuel line rest against the manifold. I think this has punctured the line and while looking like oil, its actually heated and evaporated petrol. I can't see how oil could get there. I am a bit lucky it didn't catch fire. I think I'll replace that hose before I drive it anywhere.

e2a: Running it up and very extensively checking the pipe, no leak is evident anywhere. This isn't under pressure like and injection. At a loss as to why the left side of the manifold was so oily?

A breather hose on the left side expansion tank was disconnected. I filled it up the other day and noticed a pool of fuel on the floor. It was on the wrong side and I couldn't see any drips so assumed it was someone before me but now I am not so sure.

I see that none of the breather lines have fuel line clips, is this meant to be like that? Its not obvious from any diagrams I have.

Water header tank was coming loose. Pain to do back up without taking off the back bumper. Used mole grips on a stubby Phillips to get them tight.

While not over heating, it suddenly stuck at just past the led when coming back into London. When the fan kicked in it seem to go down a bit just not when driving at 20-30. Going to have to run it to see if this was just an air lock, I'm wondering if the thermostat has broken. The water tank is full but its losing a tiny bit of coolant so I can only think there is a tiny tiny hole somewhere in the pipes that ejects a bit of steam when fully warmed up. How you would find out where that was I have no idea.

e2a: This seems OK and in testing it out I have discovered a leak, the level sensor at the top of the (new) water tank is leaking just a little bit, load of crud around it. It might just need a bit of tightening up, would account for the small loss which is a blessing.

Annoyingly my blower has died so couldn't switch it on to cool it. Don't want to attempt that job just yet, though its not out of my ability. Summer is here and I want to use it.

Hi,

With regards to the oil, if its thick and black and oil like, it is much more likely to be oil than evaporated petrol.

If the right hand side of your manifold is oily, it is most likely coming from the cranckcase breather pipe, either because the pipe has a hole in (pretty common) or there is oil seeping out of the end - its only a push fit.

In terms of the temp gauge sitting just above the LED, did it go higher befor the fan kicked in? Mine sits betwen just before and just after the LED, going up to about 3/4 of the gauge before the fan kicks in. If the thermostat was stuck, then the fan coming on would have no effect as the water wouldn't reach the radiator.

Good luck fixing the niggles!
