I like a bit of wrinkle, me. :rr:

I find a heat gun works a treat!

well after the clutch fun i got the car to the HRDs
after some work on the carbs, float level adjusted again, and a 3 size jump in air correctors running really good
did a blast down the quater went faster but took longer
drove it home

so pleased with the way it ran and incresed confidence led me to drive it to work on the following Tuesday, usual mix of standing traffic and chaseing Audis around the M25

on the way home a large puff of smoke out of the stering column below the crush can!!!!.
A strange noise like frying bacon...!
Then the car filled up with dense white smoke via the gearstick hole and somewhere under the dash

i was quite perturbed. Landed on the hard shoulder J16-15 AC M25 and armed my self with the fire extinguiser
bonnet warm to the touch
view through the grill showd no dancing flames
popped the hood to find a huge quantity of coolant all over the place the spark plugs were swimming the steering box and igntion were soaked
the exhaust gearbox and bellhousing was covered in prestones finest. hence all the smoke

windy rainy night
Short sleaved shirt, no coat
Busy M25
no emergnecy flashers

but i did have camping chair and a pair of overalls for just this kind of occasion,
and a familiy sized tent (no space for that)

so once my heart rate returned to normal, I set up camp under the kew gardens sign and used the camping chair bag as a hat to direct the rain over the back of my seat
called RAC
said Head Gasket which was my best guess
they said you have no MOT
i said i don't need one
they said we'll send somone
i said send a truck
they said yes or course sir anything you say.....hahahahahaha
1.5 hours later
call from RAC, its a man in a van in walsall. why are you calling from walsall? he said i have no idea why its been allocated to me, he agreed that it was probably cylinder head gasket and updated the ticket from "send someone from walsall to fix it" to "send a flatbed "
2 hours later a guy who had been somewhere up the A1 picked me up took him an hour from the M25 A1 junction....

How long you been waiting mate? 3.5 hours Ohhhhhhhhh ...........

broke down 5:45 drove it into the garage 22:30

can't fault the service, once it arrives, but a Male with a bag on his head, and a large car that nobody knows what its is, isn't a priority

Anyway
filled engine to the brim
no leaks overnight so presume not a core plug out
all looked great no obvious problems, radiator ok, Cap ok, top and bottom pipes ok, radiator drain tap ok engine turned over by hand OK......

bizzare

But i haven't taken a day of work to spend it all looking at an engine that looks ok.

off came the carbs exhaust head
hours of cleaning. 2 litres of brake cleaner.... is an old holey vest a lint free cloth? i dunno, but when it stayed white, i'd cleaned enough getting to that point takes a very long time.

3 foot straight edge applied, granted its from wickes so probably not as straight as necessary.. proper one is 100 quid. can't get my 0.002 feeler under the ruler across any of the bridges between cylinders. preumeing not warped
can't see any cracks
took out some shares in copperkote and a "used once" MLS gasket from the spares pile
and on it went again. ARP snot on stud threads, nuts and washers, and torqued in 3 stages
just got to put back induction and exhaust dump oil and coolant a refill and will be good to go

yes there is a chance this won't work
Got a monotorque gasket coming for a potential re run in the autumn season....but hey the MLS cost me a fortune.

there are times when i'm not that fond of this car

what an adventure

I’ve just read that twice. Hahaha oh man - ‘man with a bag on his head’. I love the idea you just set up camp.

That would take me a season to sort that out. Kudos to Dave as always - rip it apart, get at it…

Bloody hell Dave. :lol:

You know, if I’d have heard a National news report of a man with a bag on his head setting up camp on the motorway veiled in a dissipating plume of smoke, there’s a good chance I’d think to myself…

I bet that’s Dave… :-k

needs must when its chilly mate :)


It may not have been a gasket problem

i still have no clue where the coolant got out
interface between head a block at the back was soaking with boiling coolant down the side and up around each plug and obvioulsy i didn't want to hang about checking stuff on the hard shoulder whilst recovering from the shock that i may well be on fire.

but i was doing 60-70 mph enough to make water go up as well a down
But none of it ended up on the screen....very odd

wost case scenario is a massive crack somewhere, but its not obvious
if it is i've got a spare one or two of everything, so we'll see.

what i will do is buy a new coolant temperature sender the one on there is potentially 52 years old.... :)

think my issue can probably be traced back to my tirp to the NATS last year a flakey igntion module, that finally failed on the way to last years HRDs caused what can only be described as the loudest backfire i have ever heard, i stopped tro see if i had blown apart a carb or header, was like a gun going off.

But, Managed a good few journeys since

Mmmm i'm nervous, i'm sure there is more to this, i guess all will become aparent.

all back togther,
running better than before. so pleased about that

no idea why, all i did was take it apart and put it back... quick clean and re gap of the plugs that's all
why this has made a seat of the pants difference i wish i knew why.

took it out for a 45 minute run....no issues apart from the horn and wipers have packed up ......:( presume a wash down in antifreeze didn't help.
Got back popped the hood and found both heater tubes slightly ballooned at the point where they enter the heater with a dewy like covering much like an advert for fresh fruit....Oh no.

man handling the pipes produced a bigger exit of coolant
placing them back and it stopped some what.

AAAAAAAAARRRRRRRRRRRGGH ugh etc etc well.... no..... i can't print what was actually uttered.

when cold no indication of an issue hard rubber pipes with some flexibility but set in position.
These pipes have a longitudinal ribbing as standard so no visible perishing. No staining nothing
When warm seem fine idle it for 1/2 and hour to get it warm, stat open, no problem, pipes are a bit more bendy, but no indication of leaking
When exceedingly hot seem to turn to sponge and allow coolant to well out from the center of each rib.
when bent from natural resting place lots of liquid....
now this is probably the cause of the issue. Or has it been caused by the undoubted overheating and steam production when i got stuck in the first place... either way i'm kicking myself

i can imagine if the pressure and temperature was higher a considerable rain storm would occur under the hood
and given that on 2 occasions previously i have dissapeared coolant with no indication as to where it went on very hot days, in very slow traffic....
selectively leaky spongy pipes might have been the problem all along.
i can't understand why a leaking pipe doesn't splatter the screen, yet a leaking radiator cap does....

when you bend a pipe to check its ok you bend it. you can't bend it the the other way to see if the grooved pattern along its length is hiding anything.
given that these pipes were made for approx 4 years in the 1970s, by one Aussie manufacturer i should have known, They could be 50 years+ in age or be crap repros but either way. should have thought.

new pipes 3 meters of 5/8 purchased... job done

and i retreated back into the house to curse the fact that i all i did was run it up to warm, before i started on this gasket replacement route

Far too hasty. wrong assumption, regardless of previous suspicions, leads to two days work that were not necessary
a good example of starting the work not liking the car, with your head in the wrong place. This leads to mistakes. act in haste repent in leisure


BUT on the + side
has resulted in a motor that goes just a little bit better... i must admit i was smiling on my return from another quick blast yesterday managed to scare myself in the wet ... :)

I guess I live and learn...

Trying to fix up the de mist and aircon unit vents

Plastic manifold on the car is the wrong one. It's too fat and won't allow fitment of the diffuser

The thin one necessary for the job is in a right old state

They are polypropylene. I.e. pretty awkward to glue

So I chopped up the fat good one, and plastic welded a chunk of it to the thin one

Ugly. Very ugly. But robust

ill sand down the mess later

a long time ago (2003) in a galaxy far far away
i drove west from Sydney down the parramatta road and got lost in suburbia land...

i met a man who sold me an aircon/heater unit and the heavy weight metal and plastic vent/diffuser for a H51 RHD car
he also sold me a screen and some other gubbins a load of bits of dash lighting etc

i did some work in my underground sydney garage, which involved turning the aircon box into a box of spares which i have never used.....

the aim was always to get the push button unit and the under dash stuff working even if i didn't have the under hood stuff to go with it
at least i'd have demist and an ability to switch off the heater..

well finally finished that job 20 year later

the repaired plastic manifold (above) went on
i could then fit up the diffuser under the dash. its heavy...!
remount my lambda gauge on the bottom of it

next i fitted some small plastic vacuum T pieces that i got from china into the red and white vacuum pipes, replacing what was crumbling, and re plumbed in the tubes through to the engine bay
whacked the black one onto a vacuum port on a carb

and started it

mouthful of 20 year old leaves later all good
all vacuum activators are lazy
one might not work
but i can now have hot feet hot face or hot screen....

success
