Oil Filler 405

HI has anybody got any ideas how i can safely get the oil filler cap off, its
black plastic with breather tubes coming off it, and it looks like its a new
filler, but its not secured to anything so i can't use to much force and not
sure where on the cap i can try to ease the top off.

Please Help... Thank you

When I had my first 405 in 1991 (a 1.6 litre petrol engine) I had the same
problem. The easy answer was to drive up to a Peugeot agent's workshop and
ask the guys in there how it was removed. They were quite happy to come
out and show me. The method was a sharp upward blow using the heel of the
palm. But if you are unsure I recommend asking the nice man at the agents.

 

Hi its a petrol 405 GL

 

Can you remember which part of it they pushed against?

 

It's a good few years ago but, as I remember it, they (and after that I)
banged it upward near the top. I have a feeling that it came out with the
hoses attached but cannot be certain. I would strongly recommend asking a
Peugeot mechanic as it only takes a second to show you and gives much peace
of mind.

 

so you dont put oil in your car? must be running ok not needing any oil.

 

Yes i think your right nowing my luck would probably knock the whole filler
out of the engine!!

 

Look at the dates Chris. It was 16 years ago and after finding out how to
remove the cap I never had to do it again because neither the two 405's I
had, or the 406 (which went into retirement with me and still serves me
well), have required any oil whatsoever between services.

 

That was exactly what worried me and why I went to the Pug agent and asked.

 

so why have a cap thats needs to be removed?all this should be done when
the car is serviced.(should it not)?

 

That's what comes of anticipating things. When the car was brand new one
likes to be prepared and familiar with the vehicle and, as Royal Mail
regulations state that the driver is responsible for maintaining the oil
level, one wants to know how to put it in should the occasion arise, which
in the event it never did. It is also worth knowing that the previous
company car was a Ford and that drank oil like there was no tomorrow
(although the workshops never fathomed why).

 

They're always very tight but it's made worse by numpty owners who
change their oil once a year and never touch the engine after that.
Pull the breather pipes off the cap first.
Then grip that son-of-a-bitch and twist it one way as far as you can
and then the other way and keep doing this while at the same time
pulling upwards on it. It should free itself, though on my 1.6 GL I
remember having to use a screw driver to gently prise it off.
I've got the Mi16 now and even that cap is tight but I change my oil
once every 3 months and lubricate the rubber seal with engine oil and
it comes off alot easier. Once you get it off don't be tempted to
removed the rubber rings because the breathing system needs to be
sealed.
Also don't be surprised to find "mayo" in the filler cap, that's normal
at this time of year. I'm a member of just about every Peugeot forum on
the net and everyone gets it. It doesn't always mean your head gasket
has gone.
