Petrol cap
« on: March 26, 2014, 09:03:40 pm »
The petrol cap on my Lada doesn't lock. It just screws on and a little petrol leaks out onto the body while driving.
I want to buy a petrol cap that can lock and can get one at Midas.
Should the cap form a complete seal or should it be able to breathe?
I read something about this somewhere but can't find the info.

Please help.

Thanx.

It should seal completely.  There is a separate breather from the tank

There is an interesting thread about fuel breathers on the old forum;

I doubt if you will find a locking cap at Midas for a Niva. You could fit a lock to the flap.

My Lada doesn't have the flap.
Midas has a locking one for R120.00 that you screw on and attach by drilling a small hole and fasting it with a screw. You can modify the top of the screw so it can't be tampered with.

Mine is red though, and I might fit it later still. . . .

 Are you sure the leak's from the cap and not via the breather pipe? They can have slightly convoluted routing!!

I found a rubber ring at our local masterparts that fits the petrolcap perfectly, however if i tighten it too much after a fillup there is a big struggle the next time to open it. I however have found that the black evaporator box was malfunctioning and the cause of my petrol odors. After some putty and tlc to fix the connections the odors are much less..

make sure the breather is in good working order. When it's not, your tank will expand

Hi Renb.
I had the same problem with CERATOTH.
As foosh says; a rubber O ring fitted into the petrol cap has solved the problem of the leak.
I still get a slight smell of petrol after filling up which is vapour coming out of the vent by the cap.
I think that you can buy a locking petrol cap from LadaPower. I have seen it in their online catalogue.
Regards,
Keith and CERATOTH

Hi,

I bought a locking petrol cap for mine. Within 2 weeks the locking mechanism had broken. I have since taken the lock and plastic cover off and am using whats left of it as a screw on cap.

My advice is steer clear of the lada specific locking caps as the quality is terrible.
