130 Cylinder head leak

[Vespista_ZD]

Hello...

I have a very anoying problem...my PK is equiped with 130cc DR tuning kit and its always leaking oil between cylinder and cylinder head...i tried with about 5 different high temperature silicone jointing pastes but it doesnt help...so i was thinking if someome has a 130 POLINI cylinder head to sell(that sure has better finishing touch than DR cylinder head) or if someone can recomend a good mechanic who can flat out my head?

You can easily flat it our yourself with a glass plate and abrasive paper.

 

You can also mill a notch with a Dremel in your cylinder head by using a can with the right diameter to run it along. It only has to be a few 1/10mm deep. Then put on a little Uhu high temperatute silicone and wait till it's dry. Now mount the head again, it will stay dry. It works like an o-ring.

I tried with glass and sandpaper but it didnt work...

But thanks for advice

I had the same problem. I fixed it by changing to Polini 133 Race.

Did you change the head only?

And if you did is that the head with copper gasket?

[Revolverheld]

The whole kit including the copper gasket. Works fine, best decision after all...

Have you tried Loctite 5920? That is the best sealing I've had so far...

 Otherwise I would change the whole cylinder kit
