Who needs fords hey
Well heres the 90 in question. Didnt quite fit in the workshop
does now
First remove bonnet
Right the 90 has come with the following symptoms:
Massive oil leak...everywhere
Owner has installed an oil guage.
He said
cold idle 3 bar
warm idle 1.7
crusing 2 bar
I have pretty much dismissed worn engine, compression testing has confirmed this with
bore 1 = 217.5 psi
bore2 = 219 psi
bore 3 = 217 psi
bore 4 = 215.7 psi
My diagnosis is very poor...no.... shite oil. looks about 3 years old!!!! aNd a faulty oil pressure guage, its a cheapo after market affair, and ive told him its going in the bin wether he likes it or not.
The oil leak looks like head gasket failure which is about right/due at 150k anyway.
Its been loosing water, owner reckons its head gasket but I am 99.5% sure water loss is nothing to do with head gasket. Due to no abmormal presurising, no contamination in the water and no white smoke.
After a good drive and a few 1/4 sprints the temps were well up and running normal pressure, it was obvious where the leak was...on the header tank!!! A well known item to fail. mines on its 3rd!
Also found thermo return pipe rubbing on bracktet and close to aux belt, about to pop at any time!
Also the main concern is massive lack of power. not dont laugh, anyone who has driven one of these will know they are a lot quicker than you think. They are perfect for baiting keen saxo drivers at trafic lights!
The turbo vacum pipe which actuates the pitch of the fuel mixture rod is again rubbing, im sure there is a pin hole here resulting in poor fuel delivery on turbo boost. Also its rubbing on the fuel pipe which again will need replacing
My main diagnosis for poor performance is who ever did the last cambelt has got the camshaft a tooth out. It still runs but just drops of at the top end, when it should be pulling hard.
It definatly has had some fiddling. Landrover put a warning out several times on the 300tdi. The fuel pump is about 100thou" out of square, resulting in premature belt wear.
Many landys are simply upgraded to landrovers first "recall" buy simply shimming the pump. But this one has had landrovers 3rd yes 3rd recall when they finally got round to designing a new housing and pump.
You can tell this buy the yellow paint tabs. meaning its all been changed including the fuel pump its self and the crankchaft pully will have been ungraded to one with guide lips.
My guess is the valve timing is a tooth out and more importantly the fuel mixture is way too lean. On full throttle there is not a hint of black smoke at all. believe me a properly set up pump should chuck out black smoke on hard throttle. even landrover state this.
Grille off
nice intercooler
theres a lot of shit around the intercooler, I also suspect a broken/split pipe.
AUX's out
Remove aux belt, viscus fan (left hand thread!) and pulley
Aux belt is creamed
12 pc Timing kit, can be done with out it, but its a life saver when working buy your self. And gives full peace of mind when changine the belt.
flywheel and fuel pump pegs
Remove wading plug
fit flywheel timing peg to locate TDC
remove fuel sprocket cover
Fuel pin will only line up (if timing is correct) at TDC, about 110'clock.
If its doesnt your 180 out.
Remove cam cover bolts, ive numbered mine to save time as they are all different lengths
Fill intercooler with degreaser over night
