D2 TD5 Head Gasket

**Discopug** · 25th May 2008, 05:23 PM

Well mines all fixed. It cost me $ 3,340.00 re-using my head ,crack tested and machined. Modified exaust manifold ( bigger studs ). new stem seals.
Not altogether happy.
They replaced my coolant with the green stuff and I was quoted about $ 2,800 reusing my head.
So they found another $ 500. some where, its only money.
My power out put is down but thats another story, think it may be the fuel pump is not giving enough pressure.
25lb instead of 58lb
Does that sound right ??

i run a few mitisu****y swb work vans,half on lpg,for last 18 yrs.never had the head off one of them.Also have never changed a radiator,coolant hoseor had a major engine,g/box or diff repair.

they all do around 200-230000ks before i get rid of them
they do go through batteries fairly regularly as its to hot where they are mounted.

the vans arent as complicated as a 4x4 and also stay on smooth roads etc so this probably helps.

we have had a few panel repairs but we wont go into that

if they were landys i would be broke

its not only repair costs its also downtime...

4 Bar approx, so 58 psi is right.

I got as far as hooking-up my pressure gauge to another TD5 that had a suspected faulty fuel pump only to have the pump fail totally, so I didn't get to see how low the pressure was.

Thanks Graeme
I can only assume its the fuel pump. Just want to make sure, I'm getting a bit tired of forking out the folding stuff just to keep my disco on the road !

2F & 3F toyotas were reknown for head failure.

1HDTFE need new big end bearings EVERY 100,000km Maximum

All 2.6 Astron Mitsu engines had head issues

3.0L V6 Mitsu are susceptible to head issues

3.0L Petrol Nissans cracked heads (esp in Holdens)

No Alloy engine likes overheating.... It ruins the alloy.

Fair comment Tombie.
As far as I know my disco has not over heated.
I do wonder about the method used to flush and change the coolant.
Is it cold or hot? Because the motor would surely have to be hot.
My problems started after the coolant was changed the first time.

Nope flushed cold... Thermostat should be removed...

You may be suffering from congealed coolant..

'99 TD5 with 166,000ks on the clock, diagnosed this morning with head gasket failure

Have been loosing coolant for some weeks now which seems to be due to being over pressurised. Couple of tests by my mechanic and she's booked in for the job.

I'm Hearing you Mick G.
My pocket is very empty after owning my Disco for only 70k and 18months.
But I have a change of plan.
Do the work my self.
It will save me a packet and I will know whats going on.
After my head gasket was fixed I had to replace the fuel pump.
They are $ 800 fitted, I had it sent and fitted myself for $ 440.
Not a hard job and one way to save.
