1995 Defender 110 300 Tdi DCPU Loire Blue

New or refurb

Hi all,

Looking to replace the turbo and injectors on a 2.4 tdci (97k) what’s everyone’s thought on refurbished turbos and injectors or would I be better off going new?

Cheers

Go new. It’s a fit and forget job for the next 100k then, roughly. 2008 2.4 110 Utility Station Wagon XS.

Thanks brickbox was hoping to save a few quid but I guess it makes more sense to go new!

Are you changing due problems or as a precaution due to mileage?

I ask as mine is on similar mileage approaching 100k.

Why do you think that they need replacing? They should last much longer than that.

Reason I was thinking of replacing the turbo is i had the top intercooler hose off with engine running and it’s spitting out a fair amount of oil?

Also in low revs it doesn’t feel a smooth delivery of power it’s hard to explain but it’s also most slightly hesitant then smooths out the fast you go

I’ve cleaned the maf and the map sensor, map sensor was covered it soot

I’ve replaced the scv new fuel filter and oil air filter.

I recommend checking the crankcase ventilation also....
Your description makes me think of another leakage.

Your description of "hesitation" makes me think that. Do you hear a turbo-whistle as well? Maybe it is not only one problem. A smoke test to check for leaks (intercooler, piping etc.) would be very helpful.

Edit: delete EGR if possible

Maybe hesitant wasn’t the right word it just doesn’t feel right, I’ve fitted a new allisport intercooler with new hoses.

So I’ve just used forscan and tested the injectors

Cylinder 1 -0.383mg
Cylinder 2 -1.492mg
Cylinder 3 -1.89mg
Cylinder 4 3.79mg

Looks like one injectors faulty on cylinder 1?

Another thing that didn’t look right was the air in take temps
IAT 87c
IAT2 16c
Cylinder head temp 53c

What sensor takes the the first IAT?

Thanks again
