Thread: KM's outof TD5

Autos will go well beyond that, just don't overheat them and service them.

So where does that leave us?

Hi Phillip,
Thats how 1 of the plastic dowls in mine looked when I removed the head, the other was brittle & fell to bits

I fitted a new head (AMC) with steel dowls, all went together no problems.
1999 TD5
Having said that, Im not sure how the OEM head copes with steel dowl, although im sure it's been done reading this.

The point I was trying to make maybe poorly, is that the forces are such that they bend steel dowels as well as plastic ones.

It also makes me question the chicken and egg syndrome.

IMHO it shows that it is overheating that first loosens the head from the block, and THEN shuffling occurs, and it is so forceful that it affects steel dowels as well.
So the remedy is not to preemptively change dowels but to do everything possible to prevent overheating.

When I did a head job on my TD5 , I bought all the gaskets and parts from British 4x4 on the Sunshine coast.
They supplied all the parts for the job including steel dowels.
I had also read about the steel verses plastic argument and rang them to query the matter.
They assured me that they have done dozens of these head rebuilds and that ALL of them are done ONLY with steel dowels.

PS. Another point, I notice how many of the unreliability problems seem to be coming from cars with chipped ecu 's
It would seem to be the old case of " the more you mess with the engine , the less reliable it becomes.

I now need to go out the back and dig a deep foxhole to hide in.

Ntguy.
If your car has been well cared for, I would say that at that mileage it is about half life.

Chips rule!!!!1
In all seriousness, a chip will only negatively impact the engines lifespan if it's not operated in a safe manner, or its a poor quality chip.
