Other what have u done on ur disco today

Drove my 2001 D2 back from down south to up't north, after a mud run and now got a strange squeak on the overrun and sometimes on the acceleration, if you accelerate hard it stops. Sounds clutch related, but going to check the propshafts as well. Sounds almost like a bird is living in there somewhere! I'm just glad I got back ok.

Easter clean inside and out, now sitting on four Pirelli Scorpions.

Started to use the D3 again for commuting within Cheshire, serving us well presently.

Happy Easter all

Cleaned my MAP sensor, only cos I saw it somewhere on here... dunno if that mess was bad, or normal?

Is that a sintered-bronze bush for the turbo-wastegate pivot ? Mine was sticky, so decided to lube it.
Hardest bit was removing the heat shield - two bolts above exhaust manifold were ok but the rear one was welded to the turbo. Luckily the rear part of the bracket was broken, so only had to drill out two rivets & it came off ok.
A 17mm spanner fits on that square end of the shaft to work it loose, so didn't need to remove the wastegate.
Used wd40/diesel/acetone mix to penetrate & free-off, then engine oil to lube it.
Must get a bit hot just there, is there a recommended lube for that level of heat... (?)
Not sure how long the oil will last, but next time I lose power at 2800 rpm I'll know to check this again...

Well it's obviously better!
Is the lickle hole down inside it visible and clean?
Hope you din't stick anything down it and used sensor cleaner!
If it is OK it should drive a lot better!
Well done!

Yes it wasn't blocked so a cotton rag and elbow grease was sufficient.
What is sensitive inside the hole?

I think that it is the sensor itself which I also think is the MAP and the other bit is the IAT
But others like @sierrafery will confirm.
Or you could google it.

Here is a link to a thread of mine about this sensor, the problems I was having and why!
And how it got sorted!
Also to save @sierrafery some time here is a quote from him I found on another forum.
"Hi, the IAT is measured by the generally named "MAP sensor" in the intake manifold which actually has double purpose and gives both inputs(hence it's 4 wires), the sensor's protuberance is the IAT probe the MAP is the hole at it's bottom) the IAT is affected by EGR if you still have it fitted, a snorkel would have minimal to no effect on it as you said a bigger intercooler would lower it also the boost is important to be as high as possible"

I confirm, the pressure sensitive piezo crystal is in the hole for MAP output and the "probe" is for IAT
