Hi there,

I have a problem with our mondeo mk2 1998 1800 TD... (yes it's clocking on) but there's gonna have to be a few hundred miles left in her before we can afford to invest in a replacement.

The "pressure release plug" arrowed in the pic below of a Rocker Cover is missing/lost on ours unlike the one shown in the pic.
Missing presumed lost by the roadside somewhere ?

Bearing in mind that these plugs in time can apparently be loosened off from their orignal tight fit by corrosion etc.
I'm presuming that it was a pressure build up inside of the rocker cover, probs caused by possibly a blocked breather pipe.
Or even putting too much oil in the engine as well, which might not help...or maybe a combinaton of the two.

Has anyone had this happen and found that the cause was summat more serious than a blocked breather ? It would be reassuring to know that the cause of this problem was nothing more serious than a blocked breather.

I've scoured the scrappies in the area without any success for a complete Rocker Cover and found also that Ford have discontinued the rocker cover for the model as well.

One guy suggested getting some alloy brazing rods and weld/braze an alloy patch back on it... don't forget... the part is missing I would have to source a small sheet of alloy...and the thought then crossed my mind that maybe I could make up a lid and a rubber gasket and bolt it on ???

Sorry if it was a bit long winded but wadda you reckon ?

got ebay? http://www.ebay.co.uk/itm/Ford-Escort-Mk6-95-99-1-8TD-70HP-ROCKER-COVER-ALLOY-ENDURA-DE-PARTS-/400650686063?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item5d48a44e6f

having it welded may prove quite expensive...

it'd probably be better to replace than "bodge"

Yes cheers mate, my son contacted a seller on ebay this afternoon but found that it was'nt compatible maybe not the same one you've highlighted...I'll need to check it out.

Thanks

might be a difference between td and d covers?

click here: mondeo mk2 covers (will show finis codes etc) http://eucatparts.com/?action=cat_ford_unit&s_id_grp=2153&s_id_model=87

click here: escort covers http://eucatparts.com/?action=cat_ford_unit&s_id_grp=2153&s_id_model=76

escorts got the td lump, as well as the mondy. as far as i am aware should be the same cover.

there's a parts wanted section, pop a request in there, there may be one under a layer of dust hiding in someone's shed...

Nice one mate three usefull links there ...also this morning we will be looking locally at another big scrap yard.

Was actually hoping for feedback from somebody on the cause of the plug blowng out...

See original post re - "It would be reassuring to know that the cause of this problem was nothing more serious than a blocked breather."

Does the inside of the rocker case need to be under pressure ???

Cheers

the rocker cover has the pipe on it that leads to the airbox, this creates more like a "vacuum" effect to suck gases out the rocker box part of the head and then burn them in the combustion chamber. The pipe should pull off both ends, and you should be able to blow down it, and wash it out if needs be, if you can't blow down it, poke something down it, and waggle it about, i'd imagine the pipe would blow off before the cover disc popped, unless the outlet to the cover is itself blocked.

You may have not actually blown it out, it may of corroded a bit and worked its way loose, but to be honest, i've not experienced it on any of the endura engined vehicles i have known, nor have i read about it occuring on the talkford forums,

the sooty black [email protected] gets everywhere, so make sure you operate on lots of old paper, and have rags at hand, take shoes off when you go inside or the other half will get mad

I think you might just have been unlucky.

Thanks mate for the helpfull comments and I also now agree that the plug may have come out partially of it's own accord.

Regarding the rarity of this kind of fault, before posting I trawled the forums and only came up with the following http://www.talkford.com/topic/110682-mk1-diesel-rocker-cover/

I believe the common factor being the age/mileage of the vehicles.

The car is not available to work on as yet but will be tomorrow.

We have sourced a suitable rocker cover now... but the battery apparently has'nt been gettng a charge so the alternator is the next thing to recieve attention... maybe the excess oil that was getting chucked about thro' the missing plug hole has summat to do with that...or just coincidence ...but the battery is only one year old.

Anyway we'll soon be up n running ...cheers

that post was a bit before my time, lol...

just check that the parts described in that topic are not still in your rocker box, and use a new gasket. :L

hoping you're back in business, cooking with oil, (lol) soon
