turbo lag / black smoke / no power

Degreaser petrol kerosene just make sure its dry befor you install it

Really need to NADS your 4x4 asap
fit boost and EGT guages, block EGR.
fit manual boost controller and needle valve.
remove clean and check IC for leaks
As suggested clean MAF check all vacuum and turbo hoses
replace any split or perished ones

Do you know if Chip is fitted????

ok first of all im still new so whats NADS ???
second it has a bvoost gauge im working on the egt one
how do you test the ic for leaks
and isnt the boost contoller and needle valve the same
and no it does not have a chip fitted

cheers Anthony

Start the car and give it a bit of gas and feel around the intercooler, you'll soon find where the leak is.
If its a big leak you will notice you'll prob b droping boost on your gauge aswel.
As for the hoses mate have a good lock around and you'll soon spot if something doesnt look right and you will also hear a hissing noise whisle driving

By NADDING your GU you control the boost, best thing ever.
you'll never overboost ,the needle valve will control spool up rate
different to Dawes valve. Pop Mudski a PM for pricing on all the bits
required, including EGR block. Then once guages fitted you'll see whats happening
instead of guessing, Plenty written on this subject, search Chaz yellowfoot [guru]
Great peace of mind for any Direct injection zd30

and yeas i can hear a noise sounds like a leak its coming from behind the engine possable egr pipe ????

Remove all the IC hoses and check for leaks. Being over 10 years old no doubt the IC hoses will be worse for wear.
If your IC is leaking you will see it. Check the top of the engine for oil deosits and check the under side of the IC for oily patches. Number one visual give away of a leaking cooler. If its the EGR, usually, it will give off a squeal when the engine warms up. Like I said, usually. Some have mistaken the EGR leaking for a belt squeal.

Cheers mudski yeah its squeeling coming from exhaust manifold no 4 cay i just put the car in today the get compression test done as my mech has a gu4 and he thinks mine is only running on 3 i hope not

[threedogs]

Any news from the mechanics yet ??

[mudski]

I got my money on a warped EGR pipe if its squealing. Actually, which side of the engine?

[dirtygu]

Its on the turbo side mudski no 4 cyl exhaust gasket at the top

Ok got car back compression reads as this. 1) 400 (2)400 (3)100 (4)50
They think its just valve adjustment i took it to hi tech diesel
So yeah now i dont know what to do

[happygu]

Don't want to be the bringer of bad news but no compression on 3 and 4 doesn't look good for the pistons, especially since it is an early 3 litre ......
