My 1992 126 BIS restoration project

Hi Lee, the video you put up says its Private so we can't watch it, A couple of things to mention is the head you put on the CC700? did you check that the face was flat and not warped,

[Gadge]

I'm still thinking maybe the block is to blame. Two heads, two new gaskets and still not water and air tight?? 

[poxxxy]

Yeah the head is cc700 pete. It was on before without any leaking, tightening sequence followed all the way and torqued by the book. Valve clearance set as per Haynes manual and from what I could find cc700 valve clearances set the same. Will sort the video out now . Face of the head and block looked alright to. previous gaskets taken off show there wasn't any water leaking anywhere it should have been before hand .

This was the original problem when the car "just needed plumbing in"... a leak from a similar area... possible low spot from someone bashing away at the block to try remove the head perhaps.

With copper head gasket and skim it was sorted... I then ended up taking that off a few times and changing gaskets and changing heads...the leak didn't exist at any of these points...

I take it apart once again and order some gaskets from fischer 500... they send me 2, which I thought was strange (when I ordered one)... and they were cheap... I take apart the engine and perform more things to try and sort out the engine oil burning (so I replaced the piston rings blablabla). Assemble it all very carefully over the course of the week out of the car... add oil, add water expecting to be then plugging in vacuum lines and setting timing etc and water squeezing out of this whilst filling the coolant tank up .

I have to say, I've not been impressed with the athena gasket templates at all in general. Very poor... so I have a feeling the crap gasket is to blame here perhaps .

The head gasket in the "big engine gasket kit" was much better to be honest... and the copper one I originally had was good... but a big expensive waste after having to take apart the engine apart so many times . lol. So I obviously didn't want to have to spend loads more on the gasket once again .

[Pete126]

Rite.. it could be? that the CC head is slightly thinner and with a thin gasket the head will not torque down properly, what i would try is put an extra washer under each head nut and re-torquing the head down again, it maybe that you are tightening the head nuts on there thread and not head, Its worth a try!

[poxxxy]

Hmmm perhaps, cheers guys. Guess ill have to strip it tomorrow once again. May even be tempted to use an old gasket if it's thicker as the last didn't come off too badly. That or the other new one fischer sent and some gasket sealant!

 Need a clean tray to catch the oil to save for the future as I can't keep buying more lol.

Does the rad switch work independently to the temperature on the dash (which I think works off the water junction on the top of the engine)? Where should the needle sit (if I manage to get it water tight) and what fan behaviour is correct?

[poxxxy]

Got it started, still exactly the same although smoke looking maybe a tad more grey/fuelly.

I can't do anymore . Done everything I can think of to be honest now and got nowhere.

Setting up the fos carb seems to be a mystery even to the polish and without a working good carb I can't rule that out.

It's a shame no one lives around here who might be able to help out. Only thing left to try is another block (but I really can't be put through all this again). It's a shame I couldn't take it somewhere to be sorted out!

The rocker cover although new and non-deformed still holds the 2nd cylinder valves open when tightened up enough to stop oil leaks there at the gasket.

[andyzeetec]

I think anyone would have had enough by now 

did you do a compression test to discover 2nd cylinder valves open, how about making a thicker gasket or even using gasket maker & glue two together, or maybe drop tools for a week and go on holiday?

I know what you mean about the polski 30s2H carb, I fitted a service kit to mine, but cannot set it up properly as the fiat workshop manual only covers the weber DGF30 (float height is same though, 6mm and 13mm)

Float height isn't the same actually, 8.5mm and 13mm according to polish site I discovered lol. There's a couple of other measurements it gives to but I'm not sure what they mean. It has pointers to all the screws though so someone with good english/polish could probably make sense!

The rocker leak still doesn't explain everything thats going on with my engine unfortunately so still totally puzzled. Sounds sweet as a nut despite the smoke at idle though. So close but so far!

[andyzeetec]

Thanks for the link, Axle G told me 6mm. I'll adjust that at some point.

Doubt it makes too much difference to be honest . The 8.5mm and 13mm measured from the face of the gasket btw.

I need a fairy car mother to take it away and fix it up at the minute!

In an attempt to lean it out as it smelled a little fuelly I tried adjusting the mixture screw (according to that polish site the bottom right one when your looking at the choke/throttle etc.) earlier but only seems to want to run when its fully screwed in and dies when unscrewing at all.

[Page put through goole translate]

[poxxxy]

Yeah I did that Pete... but this means nothing to me:

"Repeal the throttle and flight while the boot device   B = 0.75 ... 0.85 mm
Repeal the throttle boot after activation of the actuator pull-down off the boot device"

[Pete126]

I think that refers to the vacuum unit that increases the revs when the cooling fan kicks in, I'll check the fiat workshop manual when I get in tonight

[poxxxy]

Ahhh my engine has yet to reach 90 degrees for the fan to kick in so I wouldn't know . lol.

[andyzeetec]

thats a bit strange, my idle screw is 1.5 turns out (dies when you screw it right in, as that leans it right up)
