You've probably answered this before, but I can't remember:
- At what mileage did you replace the injectors?
- Using what? (OEM, service, something else)
- What did it cost?

I had good oil pressure and no obvious signs there were any problems but
the one bearing was definitely on its last legs...

All this worry about 1HDT big end bearings is news to me. Some guys on
the French language 80 list have over 500,000 km with only injector
changes.
When I bought mine, just as a matter of general practice, I made sure
the motor had good oil pressure at warm idle. If that's low, it points
to big end bearing wear (among other woes). Good oil pressure at warm
idle is a sign of good motor health, at least as far as the components
under oil pressure. I've got 265,000 km now and no sign (or sounds) of
big end wear. No repairs, only injectors changed.

MessageHi Reno
As far as I can remember my oil pressure was ok or normal when my Big end bearing went all of a sudden on a country road in the middle of nowhere and resulting cost after the disaster was a cool 6000 euro.
I have since learned that oil flow and the quality of the oil has a lot to do with the problem in those particular years affected.
I have also nearly decided to replace the big ends when about 100,000 miles has been done, as it is a lot cheaper to replace the big ends than to strip and rebuild the engine after one fails if it does.

Hi All

As Julian knows my 93/94 TLC VX must be due some work and one of the
issues I have to address is the big end change. I have noticed that the
oil pressure has dropped slightly and the old girl is using a small
amount of oil maybe a pint between oil changes? The pressure never
dropped below half way mark even when idling but now it drops to the
lower third line and when really flogged on idle it just drops below the
line. Response when blipping the throttle is good though and when cold
it is at the upper third line until warm when it drops to mid point
during a good run at say 2k rpm. No noise from engine is evident (hard
to hear over the noise from the fuel pump but that is another story) and
no traces of metal when changing the oil. What is the consensus from
the members as to what we old TLCers should be looking out for?

Current list of jobs:

Replace birfields, replace rad, get injectors serviced, test Alternator
as output fluctuates and is making me nervous, get valves adjusted,
replace rear disks and pads, complete new exhaust, fix lazy passenger
door lock, replace radio with a better model, clean fuel pipes and trace
why the car runs rough facing uphill, replace brake pipes as they are
corroding. What works?? It starts the second I turn the key, the
starter turns it over once and the engine is running. Its an old car
and it is showing its age but I love it!

All the best

Simon, I would be looking at changing the big end bearings, removing the main bearing caps and inspecting. Change main bearings if needed, I am not sure if there is a cunning way to do this in-situ - some research of the Birfield archives is needed - or a post to lscool, someone out there will know.
Have you done a compression test or a leak down test?
What is the oil change frequency?
Are you looking to do all this yourself?

Hi Guys
What will a compression test show up and what is involved in this proceedure.
Can valve stem seals be replaced easily and by that I mean without taking the engine to pieces.
Does anyone know of a place that sells the turbos for the cruisers or the seal kits or does an exchange on them.
cheers

The gauge showing what it does seems pretty normal to me. I too would
appreciate thoughts from others.

Hi Gareth,
You cannot remove mains caps as the engine only has one it is a gigantic
cradle running the full length and width of the engine. Subsurface
fatigue failure only seems to occur on the big ends and generally only
with NON japanese style oils.
Cheers,
Craig.

Craig - thanks for the reply.
Can the cradle be removed in situ or does the engine need to be removed?

Hi Gareth,
You can replace the big ends fine in place. To replace the mains you
have to strip the front and rear off the engine before you can remove
the cradle it is a really major teardown but it does make the block
extremely stiff.
It is extremely rare to have to replace the mains except for a major
overhaul you can monitor bearing condition with used oil analysis as brg
failure, if OEM, will show as higher levels of Aluminium and Tin in the oil.
Cheers,
Craig.
NB: I just use Amsoil's 5w30 series 3000 full synthetic and don't expect
to ever have a brg problem.

Craig thanks for that.
I have switched over to Halfords semi synthetic 10 / 40, I used to use Fuchs (Silkolene) 10/40. JB is having some fun with Amsoil - high consumption, glazed bores - worn valve seals. Definitely no external leaks. We checked his boost pressure - just under 7 psi max (0.5 bar) under load engine warm, seems a bit low?
BTW - I have the oppurtunity to get a 1-HDFT - short block, head & valves plus inlet manifold and various other bits for about =A3450. It is from an 100 series auto. Any idea if the crank / block is common to the 80 series 1-HDFT MANUAL?
Thanks Gareth

I thought the "E" stood for the electronic management of the injection pump, but presumeably if all you have is the short block and head that's by the by. I suppose the intake might be subtly different to provide instrumentation for the electronics, and the 100 series with FTE engine has an intercooler (and an extra 35bhp), but opinion seems to be that binning the EGR and other emissions gubbins on the 1HD-FT improves matters anyway.
Regarding your original question: I haven't a clue. You'd think that they wouldn't change more than necessary between models, but experience of the Japanese urge to modify suggests otherwise! I would have thought posting the question on 80sCool forum would probably get a response from NZ and/or Oz. But =A3450 for a block & head sounds amazingly good value.
