Oil fumes from the head cover

[petroscf]

Are there available gaskets for these or we have to custom cut and fit one?

It still seems that the fuel pump is not working well, and probably what I see on the insulation foam is fuel not oil? Mechanic says we should fit an electric pump
I wonder whether a not working properly fuel pump can be related to excessive blow by?
(Although reduced, I still have the feeling that oil fumes should be less than that)

A bit early for conclusions, but probably fuel pump replacement was the solution to the problem? Have continued this topic in my build thread

Coming back to this topic I 'm afraid
Yes the fuel pump issue maybe shouldn't be mentioned here, in any case we finally decided to delete the mechanical one replacing it by an electrical, I am not sure, maybe we should have stuck for a bit more time with the mechanical, until a solution was found?
Anyway, blow-by fumes is the thread's title and this is what I am revisiting this old post for.
After replacing the piston rings with "softer ones", things are surely better, but still some blow-by fumes make my head dizzy some of the time
At the moment the connection set up as it is in the engine bay, seems not to be completely proper. I'll try to describe it, as I haven't yet started solving the photobucket problem so no photos for some time. Hose connected to the blow by outlet on top of the rocker cover.Oil catch can connected at the other end of the hose. Second hose connected to the catch can's outlet, with small air filter on its other end(so, open to fresh air). I understand that there might be an issue with the type and quality of my oil catch can itself. Ok let's say I can take care of this, by checking if the can is baffled inside or by ordering a new catch can-a more expensive one perhaps?
However, my car has twin sidedraft webers with open, "trumpet" type air inlets. Do I have to replace trumpets with airfilter boxes for example, in order to send the rest of the fumes inside? Or is there another way?

I believe this is my oil catch tank

Or at least it looks very much alike

Also, forgot to mention, that a friend with experience in M10s, insists that I should leave the final tube free, and not reconnect it to the intake, or my engine will not work properly
Don't know what instructions to follow

Did you find an issue to this one Petro?

Hi now this is a very old one, so the answer is yes and no :

This engine made it with difficulty at a bit less than 9k km and went to scrap, mainly due to bad block, I'm afraid.
I think I've mentioned this somewhere in an older post.
Now I am near 30000 km and at least 6 years with the next one, same concept but based on a good block and, much better specs and parts - and no problems

However, regarding the fumes, a long soft tube is connected on the outlet of the rocker cover, that drives the fumes somewhere underneath and lets them out.

At the moment this works perfectly well, it only is a bit smelly

Thanks for the reply, I am wondering whether to do the same. Does the hose have a non-return valve on it?
