Just because you're offended doesn't mean you're right.

2010 Defender 90 Puma 2.4 XS CSW Galway Green

Hi both

Just about to attempt this exact same job!

Was innocently replacing my injector seals due to an oil leak down the nearside & rear of the engine, of course soon learnt it would be the injectors (new to land rovers but always wanted one so found this very tidy puma locally) the injectors were tested & 2 replaced approx 2 or 3 years ago but leaking again or always were after re install at the previous owners indie garage he used.

Anyway - I have a injector cleaning bung like in your picture in my cyl 4.... it's back breaking enough reaching over to anything that far back while stood on a stool at the nearside wing.

Just ordered a sealey 4mm flexi magnet as per recommended on the post

thanks & the spring compressor also!

Just a few questions;
1) can this engine be turned clockwise AND counterclockwise by hand or clockwise only?
2) does the valve freely drop into the cyl easily or do I have to move it from the top?
3) does the piston move it back up high enough to easily refit the collets?
4) are the collets on these a traditional 2 piece taper type?
5) did you bother replacing the rocker carrier frame bolts or not? Is there a tightening sequence to avoid busting it?

Any of you in Gloucestershire and fancy lending some moral support? I won't get over the sinking feeling I had in my gut the moment I realised what had happened!

I have removed the inlet manifold but not fully due to all the gubbins & junk around it will this suffice?

Cheers in advance:)

One more question, do you have to put the engine into specific position to remove the rocker carrier or can it be removed wherever crank/cams are ?

She runs a treat much to my relief as you can imagine

Crazy happy seeing that bl33dy item come out on the end of the magnet

Next stop is a frame ball joint & check / replace mt82 output shaft but I have a very reasonably priced local specialist that's happy to tackle the shaft
