Yeah Mike, if you look back to #43 you'll see the pic I posted with the puddle of diesel around the Base of the injector.
That's why I asked about boost pipe Mike.
Show me a picture with a wider shot of the top of the engine Dave please.Ok eventually we get time to look further into the prop issue. It's looking like the donut. My neighbour is going to do it with me when we get a minute between us. He too works silly hours.
We now have a lack of power issue. It chugs on tickover and there is no power until the turbo kicks in and then it isn't great compared to what it should perform like. It's a 170bhp diesel so should pull well.
I was advised to change the fuel filter which I have done this afternoon as it could well be blocked. So I've done that and the air filter and it looked liked they hadn't been changed in years but no change to the performance.
I decided to take the top engine cover off to have a look and found a puddle around one of the injectors.
I ran the car to see if the flexi pipe above had a split but nothing came out so starting pulling the electrical connectors off one at a time to see if there was any change in the running. Pulled no3 off which is the one with the puddle and nothing happened.. So it's now got to go in and have the injector repaired. I'm sooooooo happy.

I'll have to whip the cover off in the morning Tony and take another shot. Why what you thinking?
Not sure until I get a better look see mate. When you rev it, do you get a lot of noise? Would help if I knew whether it has an inter-cooler or not.

Erm not noisey just a bit rough and flat as a witches tit. Don't think they have intercoolers mate. There's no air intake in the bonnet.
A 2.5 diesel will almost certainly have a turbo so will also have an intercooler.

Intresting Ian. So we have an intercooler then. What alarms me reading that is we have a bad oil leak, so much so Jue is banned from parking it on the drive. After today's findings though put it down to a sump leak and the excess diesel from the injector being blown back and running down the back of the block, mixing with the oil from the sump, getting onto the cross member and dripping onto the floor.
A blocked air filter can cause oil to be drawn from the turbo reading that post. I guess it's literally sucked out and blown into the intercooler.
Can't recall. Have you changed the air filter?
Check the intercooler first. Might also be best to check the oil level.
You can pick up a used intercooler for £60-£80.
There is always some oil in the inter-cooler pipes mate so don't too alarmed. Just because an engine has a turbo it doesn't automatically have to have an inter-cooler, if it has you need to check the boost pipes for splits. When you rev the engine these thick pipes will expand and you can feel this by squeezing them, if they don't expand then it's a fair chance one is split.

I thought I'd add my bit in
My seat alhambra burst the intercooler and every time it came on boost sounds like you've got a giant snake living under your bonnet power down but smooth running.
still could be an injector .
I can sympathise just spent tonight removing my tandem fuel pump on my skoda superb got a replacement trying to trace a misfire type problem 2-2500 rpm will fit tomorrow hope you can get it sorted.
Another pair of eyes cast over it might help.

Said that Tony as most turbo engines will have an intercooler. Simply compressing air heats it up considerably. Cooling that compressed air making it denser means a greater charge in the engine so more power 10-20%.
It still doesn't stack up that disconnecting the injector has no effect though. Hope we're not chasing multiple faults.
Changed the air filter last month Ian and cleaned it out yesterday. Jue goes up a really dusty farm track everyday and they advised us to bang the air filter out regularly as it's a really fine powdry dust and it gets everywhere.
Am guessing you didn't need to change the filter in the FL. It's air intake is high up right behind the headlight and well out of the way. How dirty was the air filter?
The original I changed wasn't great and the fuel filter looked like it had been there donkeys years. When I cleaned it out yesterday it wasn't bad to be fair. I'll do it once a month as it's really easy to get at. One of the other liveries at the farm has the same car and he suggested doing it as the track is lime Stone and the dust gets everywhere.
Can you see an i/c? What state is it in?
If the car picks up on boost i wouldn't have thought the intercooler was not at fault. It would be flat through the entire range not just in low revs.?
If you had a boost leak you'd likely hear it.

It does pick up fairly well but not as it should. It's the bottom end. There's nothing at all unless you slip the clutch a bit to get it going. There isn't any noise.
