This afternoon I started converting a pair of rear hatch stays (the only pair I will have available until I re-order the friction locking mechanisms) ready to take to National for a club member.

Been working on getting my new gauge panel wired. Took the car for a little spin just to stay motivated, and pop went the windscreen. Two steps forward, one step back as usual. So I vacuumed up the glass and flogged it around anyways.

Fitted new pipes from twin reservoirs to master cylinders
Bled brakes and clutch
Refitted fuel tank
Removed old reservoir/pipes
Bolted new bucket seats onto floor brackets (adapted mini ones)
Refitted seat belts
Replaced cooling pipes after fitting new High Efficiency Rad.

Just awaiting Thermostat housing gasket so I can finish fill up with coolant and start engine again!!

Last faffy job is to rewire the twin temp gauges circuits (its a mess at the moment) and install new temp gauges - then I can see how hot it gets!

Refitted thermostat housing with new gasket and thermostat, plus some blue gasket sealant, left for a bit then started filling rad up = water started pouring out of thermo housing, and when I took a look from underneath - all over my face - quickly filled a bucket with water and dunked head in it!

So ordered another Thermostat gasket and ill try again next week, any tips on this one?
[*]I will clean and emery paper both surfaces (so got that bit)
[*] BUT if the thermostat is shut, do I need to fill rad, then run engine until warm, and wait for thermostat to open and water to circulate before filling up with more coolant
[*]THEN does the bleed valve at front of car need to be open or closed when filling system
[*]AND what proportion of water/blue antifreeze should I use
[*]FINALLY I have previously broken studs on other vehicles by over tightening, how tight should these be - I have a 6 inch long 1/2 inch ratchet spanner that I'm assuming if i tighten as much as I can with that it should be OK, not sure I can get a Torque wrench to the nuts and I think I could overtighten with my standard socket wrench.

On the plus side managed to get 1978 Suzuki GS550 started for first time in 4 years!

What probably happened was the thermostat wasnt seated properly in its recess, can be a bit awkward when trying to do it in situe from below the car, then when you fitted the housing it prevented that from pulling up and sealing hence the leak?

That'll be it. Thermostat not seated. We've all probably made that mistake when fitting it with engine in the car. :) Clan004

Thanks chaps, I did wiggle it into place but hey ho.

Glad to know Its not just me, is there any way to stop the thermostat slipping out whilst refitting the housing. Its a bit of an awkward reach so i'm bound to knock it out of place when refitting.

I make sure it's bone dry and smear a little Hylomar on both the recess and the rim of the thermostat then carefully seat it. Place the gasket on (inner side smeared with Hylomar) VERY carefully and evenly. - Make sure both stat and gasket are pressed home before sliding on the stat cover smeared with Hylomar and keep pressure on the cover. Don't let go of the cover before spinning on the nuts and seating it properly

make sure the holes in the stat cover are clean, even pass a drill bit through them one size up and lubricate the studs with anti-seize compound.

Yes, I'll be looking to order a new screen from overseas very soon. I'm in the process of dealing with my insurance company. It's a bit tricky.. although they specialize in classic car insurance, they're having trouble locating a Hillman Imp screen in the US. I wonder why... :lol:

Thanks all so second attempt...............

did as I was told by the helpful Forum Members, left everything for an hour then started car up, fine for 15 seconds then water blowing out of lower stud area around nut and washer........grr. I think when putting in thermo there is still some water/antifreeze sitting in the cylinder head that seems to attract itself to the gasket sealant as soon as its applied, will make sure all is even drier then before.

However due to mechanical incompetence I did order two Thermo gaskets last time (thanks Bob), so i'll have another go this week, happy to do the refit process its the cleaning of all the old blue stuff again from housing etc that is a bit awkward.

We'll get there..................!! If not i'm calling Graham!!!!

If the head face is flat and the thermostat cover face is flat and the thermostat is correctly seated and studs are still decent you should hardly need any sealant and just the one gasket should do the job.
Head face and cover face need to be really clean, flat and undamaged by corrosion and the studs and their threads cleaned.
I still think youre dislodging the stat as you refit the cover thus stopping the cover seating correctly, if so no amount of sealant will do a good job?

How did you get the old cover off? if you had to lever and hit it to get it to shift you might have cracked the housing/cover, the cover can crack around the stud boss or maybe a bent stud that too might prevent it pulling down squarely?

Thanks, it just seems to be coming from the housing where stud comes through, around the washer and nut.

I did clean the head and cover, they were ok, I think I may have been less thorough on the studs. Cover came off by hand with a bit of wiggling and is definitely uncracked, and I seated thermo with a bit of 'blue'.

So I think it points to another clean and concentrate on studs a bit more, i'll then be extra extra careful re applying the sealant particularly around stud hole in cover - someone here has just told me I could have messed this bit up if I didnt offer the cover to the studs carefully (lying on my back with my arms twisted around various bits of car!!) - ie it needs to slot on without catching the sealant on the top of the studs.

Oh well, third time lucky...........care, patience etc!

Check the thermostat housing for cracks, they can be quite fine and difficult to see.

So after reading everyone's advice, and hopefully following it:
[*]I checked thermo housing carefully, using my best glasses and cleaned it and rechecked, no cracks
[*]I cleaned the surface of the block where thermo and housing go and made sure all was dry
[*]left for 12 hours to make sure it was dry!!
[*]carefully put gasket sealant on gasket, making sure sealed around stud holes, did the same with the thermostat housing , and a little around the thermo itself to hold in place and left all for 10 mins as advised on sealant tube
[*]carefully placed thermostat in place, gasket into place over studs, and the same with housing, then pushed together added nuts and washers and tightened with ratchet spanner

..........went home to allow all to set (12 hours ish)

This morning, went back, had a look (all neat and tidy) then started filling radiator..................only to be met with sound of dripping water. Again its not coming out of housing or the housing/cylinder head join, its dripping from under the washer on the bottom stud.

So really confused,cant see how it can get to stud with gasket and sealant present.........surely the stud locates into a hole thats closed at the other end and not open into where water is?

Anyway, run out of gaskets now (Bob about to be emailed - again, he must think i'm some kind of gasket hoarder!!), and i'm going to ask local garage man to fix it - I think as coolant only leaking slowly, a 3 mile drive to his ramp will be OK?

Getting so fed up now, I might go and look at an Avenger!

Tiger, or at least a twin headlight GLS. Great cars :D. Oh, sorry.... You were after encouragement :oops:. I'm beginning to think that someone has wound that stud in too far, and into the water jacket. :shock:

Its OK, at least I still have a sense of humour (just!). It wasn't leaking before I removed housing so can't see how it could have done that now........................i'm assuming studs are a bother to remove with engine in place - only way to check as well I assume. Still I'll order from Bob and see where we go from there. I'm planning to fit a 930 but wanted to get this engine running and cooling properly so potential buyer can see its all OK. As engine will be coming out I'll show him it as is and sort this out after removal.

Twin headlamp Avenger with Sunbeam Ti engine - only thing is I need to sell the Chammy before I can but another car!

So anyone up for the Chammy Coupe with a 930 engine and a buyer for the 875 sport one,new clutch, HE rad, disc conversion, new Master cyls, new clutch , lots of big rally lamps and a current MOT - £6,000 and you'll get £600 back for the sport engine?

Top hose, is that good and not split, even ones recently new now soon perish and split, can't see how if you've sealed it all properly its coming from anywhere else now?

Do the nuts tighten evenly across both studs?

So easy to lose threads on corroded studs - OR more likely a nut hits a corroded spot such that both *feel* tight but pressure on the stat cover is not evenly applied across both studs.

As moose said in an earlier post - running a die along stud threads and applying Coppa Slip to the threads /nuts ensures even torques.

FWIW. I now make my own gaskets cut from a sheet of thick gasket card (from Frosts). The thicker gasket embeds better on uneven corroded surfaces and is much tougher than the commercially supplied gaskets - ie. they don't rip or stick to the housing/head -they always come-off in one piece, The thick card is also a good medium for the Hylomar to adhere to/soak into. You just need to invest in a set of Imperial stud hole punches - (not expensive off ebay).

https://www.frost.co.uk/gasket-combo-kit.html

Using the thick card (plus stud hole punch) I've make gaskets for:
  • Sump
    crankcase water jacket inlet
    Oil filler neck
    thermostat housing
    cam box.
    The card is too thick for the timing chest gasket because and it affects the fitting of the head and sump - you need the commercial gasket for this.
Bonus is you can make these gaskets in minutes / don't have to wait for the post and they perform better than std! Clan004

Hmm thats interesting, it is a new hose, cut carefully for the auxiliary temp gauge sensor block. It did slip cleanly over the housing and is secured by a new jubilee clip suitably tightened but I suppose I could have caught it and its leaking from that onto the next lowest point - the stud.

However when running the engine the water does seem to spray out from the stud top area (cant see 100% as i dont want to lay under car whilst warming coolant is spurting everywhere). I will check the hose fitting first - might even be able to see that from back of car.

So is it possible for a stud to go through into the water jacket? And if so why no leaks originally..................?

Bob on the case re gasket(s) etc!!

Thanks all

Wow, message to everyone, I really appreciate all the help and advice on this! Thanks

Nuts do appear to do up evenly and with no apparent obstruction/cross threading issues and sit cleanly against the washers. My tap and die set is on trolley by car as we speak! I have ordered new studs and nuts from Bob, not sure how i'll get old ones out though in situ.

I had thought of the MYO gasket route, as I need a few odd ones for the Stag as well, i'll certainly have a go!

Thanks

Remove the studs by either: - two nuts counter-tightened - undo stud with ring spanner on inner nut.

Or if enough room - use ...

....stud removers.

TOP TIP: (But NOT possible with thermostat studs in situ as no room to swing a hammer) - giving studs a hard, sharp, tap on the end of the stud with a hammer, shocks/loosens the grip of the casting threads interlocking the stud threads making them easier to turn. :) Clan004
