That's strange, i'll be watching to see what causes this, you've covered pretty much everything.

 

What about adding gasket goo to the spark plug tube seals?

 

cheers!

That's weird. Does it collect in the spark plug tubes if you just use regular leads? Like ones without the big rubber plug ends..

When you say you replaced the plug tubes, did you get new ones our pull them out of another motor?

And are you sure that's were its coming from? Could be a leaks tappet cover gasket!

its 100% coming from the spark plug tubes I've analysed it long and hard haha its pooling in the tubes. and i mean i replaced them with fresher ones from another motor. I've also discovered that there is only actually getting onto the ends of the plugs in the combustion camber (this means the pooling could be caused by oil in the combustion chambers and being forced from the bottom up into the tubes on full boost) , that says to me that either the valve stem seals or oil seal piston ring are gone. next step change the valve stem seals see if that mends the issue. because all other options i can think of are exhausted.

I highly doubt any oil could get past the thread of the spark plug, especially if you've over tightened them.

I too had the same pooling issue, tried swapping tubes from other motors but only managed to fix it with some new genuine items.

Don't know if you can help. Do you need to run a rising rate fuel regulator(designed for turbo run a boost line to reg and flows more under boost)? I m building a draw through ke10 and got the rising rate for carb turbo.. but not too sure if a single Stromberg su thing will need it..

You don't need a rising rate reg for draw through, carb isn't under pressure.

Thought so.. guess I can sell it then... Cheers as always

What is it? I wouldn't mind replacing my noisy malpassi

Malpassi - but carby turbo malpassi - so low pressure
