triumph stag v8
hi all,
doing a head job on a friend stag hes just bought!
still got the triumph engine!
only major prob is that who ever has had it b4, has use rad sealer,
got 1 of the heads off,
and all the water ways are blocked solid!
and i mean solid,
looks like solid lime scale!
any ideas if it can be removed !
been a mechanic all my life and have never seen anything like this !
it just solid!
any ideas ?
(apart from a new head/engine)
cheers paul

The usual way is an acid dip.
Means you gotta take out the block and remove everything since its gonna get immersed in acid, believe its phosphoric.
Come to think of it, you dont hear of many people doing it anymore but that was always the way to do it...

I've worked (for weeks) on trying to get a friends triumph straight 6 to run reasonably well. It's just won't, such a lame engine
design I hate it! I wish he’d just throw the lump in the skip and fit a pinto…

never come across or hear of this but mmy way would be to use meachincal means i.e. chisel/screw driver/drill etc. to get rid of it os mkae hole and
then use checmicals. you would need to remove core plugs to gain more access.
if it is limescale, then acid will dissolve it, if it solid radseal stuff then I dunno what that is composed of so cannot suggest how you would shift
it. A call to the manufacturers of radsel may give some ideas.

As already said you will need to acid clean it --- beware don't put anything caustic such as drain cleaner near it ---
PS congrats on getting the head off without shearing bolts ---- those angled head bolts strange bit of design main cause of the head gasket failures..
b-awful engine nothing like as good as the Triumph 2000 Straight 6

Triumph stright six is a very smooth running engine, very reliable in 2000cc form. I had a client a well known TV entertainer who ran an ex police
2000 for years ended up with a truly intergalactic mileage with no major work done.
The 2.5 was less good mainly because of the Lucas injection and longer stroke.

A Pinto Stag 
A big fan of the triumph straight six.
I have 4 in the workshop.
One would be going into the roadster if it were not for the weight issue.
Just love the sound of them

yes it's the 2ltr one and I've never seen such a lumpy running heap of poo, it's even broken down twice when I've tried to use
his car leaving me stranded and had to walk for miles, once in the pouring rain...
sorry but my dream is to crush it with my digger

Lovely smooth engine ! Would suggest you start with the basics , points/dwell angle, timing, valve clearances, carb diaphragms/pistons ,air leaks ,
balance etc. Dead easy to work on and simple

I was considering buying one of these... only with the Triumph original engine as although they were a bit of a pig initially - minor rework can see
them being reliable and basically trouble free. Apparently this engine is better than the Rover V8 interchange which regularly happens but drops the
price...
Get in touch with the Triumph Stag Owners Club (UK) - they have a website which is very informative. They may be able to help you.

Agreed, I'm sure I read somewhere (many years ago so I can't remember the reference) that it was used as the core of some helicopter
engines. If it's lumpy and unreliable there is something wrong with it or the fueling/electrics.
