Engine rebuild brains

I don't suppose anyone that knows about engine rebuilds would like to
accompany me on Monday would they? Someone who knows what sort of thing to
look for as the head is stripped off to see where it might have gone wrong?
I might as well wear Joo Janta 2000 Peril Sensitive Sunglasses and carry a
white stick for all the good my knowledge will be!
I'll pay you - sort of :)

It could be many things that may have gone wrong
1/ head not tightened correctly
2/ block face not cleaned so gasket has not sat correctly.
3/ gasket could have been damaged during install
4/ they may have used head old bolts that have may stretched so will not
tourk up right as the bolts may be to long to drop in to the bind holes
in the block
5/ could have a blockage in the water system causing back pressure
6/ head cracked
7/ block cracked
8/ badly corroded / scoured block face ( may need block skimming )
Best advice is to take note of what some of these members have told you
1/ get the pressure test done before you take the head off that should
give you an indication of where the problem may be I.E which
cylinder/area you need to pay more attention too
2/ take an independent (pay them if you need to)
3/ get the head tested
But it is your call, only you can sort it out. If not just pay the bill
and swallow your pride and put it down to a bad experience however
expensive it is.
Of if you scrap it I have the spares ;-)
Good luck
Yours
Ray

Don=92t let ray *have* it, I will pay you, lets see, at least =A3200 for the
engine, box and axles. Is it a manual or auto?

I know all that Ray
But it makes a difference if someone actually knows what to look for which I
don't. Something might be wrong and staring me in the face but to the
uninitiated it might be missed.
Pressure test has been requested.

Peter,

I would like to but work requires me be busy, not sure feel qualified on you
engine to be useful - two pairs of eyes are always more useful though.
Do some checking on leak down testing and ask them if they can do it =96 only
needs a compressor and a gauge with an adaptor to fit a spark plug. My
thinking, although checking for a cracked block hasn=92t been mentioned in any
of the write ups I have seen, is this;
Put leak tester on and check with no 6 at TDC, do same with no 5 (and rest
if you want). If the failure is gasket, you will see a rapid pressure drop,
if it is a cracked block you most likely won't. It would be nice to put the
engine at BTD on no.6 and repeat the exercise but I think the exhaust valve
will be open!
What is the normal way for these blocks to "crack" if the do fail in that
way?

Ask Colin the one I told you originally to use.
He may go with you if you cross his palm with silver
But you will need someone that know something .it would be best to
speculate something to get some one there at least to protect your
interest
If I knew enough I would go but I don't. Try phone around to get some
one the AA or RAC might be able to help if you are a member some groups
do offer support like this, what have you to loose eh
Oh by the way I will increase Malcolm Bagley offer I though in a copy of
auto trader & fluffy dice so you can get another one.

Do you have Colins contact details please?
Hindsight is great but the reason I didn't go to him in the first place was
having to get the LC trailered there.

So do you provisionally accept the auto trade and fluffy dice offer
then?

How does a phrase that contains two words that sound remarkably similar to

I've arranged for a mechanical repair assessor to visit the shop with me to
watch the stripdown and then compile a report. This will be done 19th June.
In the meantime I've got them to run a compression test on the cruiser -
pots 1 through 4 are 185psi, 5 is 195psi and 6 is 190psi. Does that give any
further clues to anyone as to the state of the engine?

Not knowing much about it Pete I would say the pots sound ok to me
,there is only a 10 psi difference which I think is ok ?

If there was a crack in the block venting into the coolant system wouldn't
the affected pot be down on compression???
I'm getting very confused now.

I don't have the figures for the petrol engine, but those for the
unturbocharged diesel 12h-t are 400 to 427 psi, and its compression
ratio is 18.6 to 1. The compression ratio for the 1FZ-FE (I think
that's you) is supposedly 9.0 to 1, so on a not terribly scientific
pro-rata basis you should be looking for 193 to 207 psi.
The permitted variation between cylinders for the 12h-t is 28 psi, so
again scaling by a factor of 2 suggests 14 psi permitted for you.
On that basis your engine sounds a bit worn, but not unreasonably so,
and the variation between cylinders sounds OK too. I'd say "so far, so
good", since there isn't a cylinder that stands horribly out.
Sorry, not a lot of help. Good luck on the 19th

According to Haynes (all I have) it should be 171 psi +/- 30 between pots??

That could be right. There would be more adiabatic heating in a diesel
(compression warming the air) and hence higher pressure, so comparison
wouldn't be exact.
It looks as if your compressions are good, which doesn't sound very like
a horrendously cracked block to me.
I know I keep saying this, but the only head replacement I ever had done
cracked when they fitted it, and had to be replaced. So it *does*
happen.
Nil desperandum!
