205 camshaft oil seal

I have an oil leak coming from the drivers side (RHD) of the engine near
the top (been leaking for years actually).

It looks like it's leaking from the camshaft oil seal. I'll take the top
section of the cam cover off to check, but...

what's the procedure for replacing the oil seal. Does the cambelt have to
be taken off? I'm a bit wary of doing this, as I seem to remember Peugeot
use a special tool to re-tension.

 

Which engine do you have? The procedure is basically the same for both
types but the XU series has an extra cover plate to remove behind the
camshaft pulley.

Remove the camshaft sprocket (and cover plate)
Remove the old seal (punch a couple of holes in it, screw something
into them and pull it out)
Clean/deburr the seal housing
Drop a little oil on the new seal and drive it in with a tubular drift
(eg a large socket)
Refit the (plate and) sprocket.

As for retensioning the belt i've made a tool which does an adequate
job (This is for the TU engine, I cannot vouch for it on anything
else), but obviously you shouldnt rely on it to get you further than
the garage..:

Find something with a square end that fits in the tensioner socket (I
used a broken thread tap)
Find a spanner that fits on the other end of your square thing, and tie
a piece of string to it 80mm from the end which fits on the square
thing.
Fill a plastic bottle with approximately 1.5L of water (so it weighs
1.5KG) and tie it to the other end of the string.
Put this all together and hang it from the tensioner so the spanner is
about parallel with the ground and the bottle hangs freely, and tighten
the tensioner nut.

Can scan you the relevant pages/diagrams from haynes if you need them.

Hope this is some use

Thanks Andy

What a dumbo I am, not giving any details of the car.

Its a 1992 1.4GR, with a derivative of the TU3 engine called TU3.2 (very
rare, apparently) ,and it's non-cat.

I have 1989 Haynes manual from two previous 205's. It has a Ch13
supplement, but it does'nt have a separate section for either Cambelt or
Camshaft Oil Seal replacement, so I'd appreciate your offer of a scan.
I'll send you an e-mail, assuming your address is as given.

When you say, "but obviously you shouldnt rely on it to get you further
than the garage.." do I need to get it checked by a Peugeot dealer or any
reputable garage (any idea what they'd charge - I'm not used to dealing
with garages) ?

Do I need to drain the engine oil first ?

 

Yes the email is valid I'll fish your mail out of the spam bin, and
i'll be able to scan/send sometime tomorrow.

Probably a good idea to drain the oil first (I always change the oil
and filter whenever i have the engine apart, as a matter of course),
but if you leave it a while after running the engine it'll have mostly
drained back down to the sump anyway so shouldnt be too much of a
problem if you dont.

'Fraid I cant help on price as I've never actually bothered to go and
get it checked...any decent garage should be able to tell you if its
tensioned correctly or not, and I wouldnt expect to pay much (if at
all) if they don't need to adjust it.

HTH

And I'd advise if you're doing that to leave the covers off so that
they can check it, else they WILL cahrge you!!

 

Andy, or anyone else that can help.

I’ve removed the Upper and Centre timing belt covers.

The area around the camshaft looks dry as a bone, so I was barking up the
wrong tree (having already bought the camshaft oil seal).

The problem now is, I can’t tell where the oil’s coming from. Looking side
on, at the timing belt end, only the front third of the block is oil
stained, and only from about a third of the way down from the top. The
timing belt looks and feels free of oil, and the crankshaft sprocket also
looks dry. The body of the alternator, but not the fan belt, is soaked in
oil.

I’m perplexed as to where the oil could be coming from.

Anyone any ideas, or know what I can try next.

 

I am not familiar with this engine but, in the past I usually found that
"untraceable" oil leaks invariably came from a dodgy oil pressure switch
that is screwed in to the block.

 

Sounds to me that the head gasket is leaking oil. Around that area is
the oil feed to the head, and there are problems with the gasket going
in that area. I can't think of anything else that would soak the
alternator. But have a look for any oil gallery plugs in the head in
that area. The earlier type were allen key plugs, and if leaking could
be taken out and resealed. Later types were a ball bearing hammered
into the hole. I've never known this type to leak.
However I would plump for the head gasket!

 

I'll second that. Just had a look at mine and there's not a lot else to
go wrong around there, except the dipstick tube is right above the
alternator...but I'd guess that wouldnt get a lot of oil on the block
from it's position.
