G'day all,

I know this is a band aid solution but is there any proven products on the market I can safely put in the engine (without causing harm to the engine) to either stop the oil leak or condition the seal so as to stop the oil leak.

The leak is not coming from the sump, its not coming from the rear but is coming from the front.

It is hard to tell if its from the crank seal or timing cover seal.

I have removed oil from the engine's sump with a rag and within 15 minutes the oil was back again routing its way from the front somewhere. The vehcile was raised at the front on an angle so its definetly from the front.

Any advice on this would be good, thanks

Most likely the timing chain tensioner seal.

Leaks from behind the P/S pump, but gives the impression its coming from the timing cover or crank seal. It tends to leak right down those paths. And its under high pressure, so it will always leak quickly.

$2 o-ring and 30 mins if your time.

arm79,

Thanks mate. Would you know the size of that "O" ring?

I dont know if it is the power steering pump as the colour of this oil is light to dark brown.

But when the engine is switched off there are some signs of oil.

I'll load some photos shortly as I've taken a few, don't know if will be much help but will load these later today or early tomorrow.

Cheers

No no... I mean the tensioner is behind the P/S pump. Not actually leaking from the pump.

You need to remove the P/S pump to get to the tensioner and see if that is the true cause of the leak. There's a high chance, as it is very common as they age.

Don't know the details of the o-ring. Guessing they'd be about an inch round and 2mm thick . If I need one I just pop into Ford Spares and grab one. They are readily available.

And also to note, if your P/S fluid is still the factory stuff, or has been refilled with OE spec, that fluid id a brown colour too. Not red like traditional stuff.

It is not an oil leak. It is a factory-fitted rust prevention system. Most fords have it, seems to have been a very popular option. :lol:

G'day arm79,

Thanks again.

I did ask Ford for a price on that Timing tensioner O ring, ...$3.77

Is this an easy thing to fix and what do I need to take off apart from the power steering pump?

Cheers, Peter

Very easy with basic tools. 10/13/14mm spanners and sockets, 3mm allen key and some pliers or multigrips.

Best thing to do is take off the P/S pump quickly and make sure the tension is leaking. It will be very apparent if it is.

Best place for a doco is do a search on here for the head gasket replacement doco. From memory it has a pretty detailed explanation of how to remove the pump and tensioner and reassmble everything.

Here are the photos of the affected area.

Might be easier to show what I'm talking about

This oil spray I noticed on the front suspension. This could have been blown onto by the fan, so I'm not sure if the leak is from the tensioner or blown o ring near the power steering pump, I could be wrong.

to me that appears to be weaping from the front side near the thermostat housing where the head and timing cover meet.

My advice is to give everything a good dose of degreaser and a clean. remove your tensioner and give it a good clean up as well. over the next few weeks keep an eye on everything and see if you can pin point where the oil is tracking from. I could almost say without doubt its from the timing case/head seal. not a head gasket but the rubber seal that runs along the top of the timing cover. IF it is, usually you can get away with some sikaflex or similar to reseal the area without removing anything.

Would be the best outcome if this is the case too.

But yeah clean it up and then inpect for oil marks.

Has there been any noticable change in your fluid levels?

Dave

actually mine and my mrs au engines both weep oil from where the head,timing case and block meet on the passenger side of the engine..
not that bad though..
but if the engine were not degreased evey 6 months or so, the whole engine would look like that within a few years..

dc_todd (Dave),

Yeah could be, I'll clean it with a gerney or high pressure hose.

I have never heard of sikaflex, Where do you get it from?

How do you apply it without taking stuff off as some areas would be hard to get at.

Cheers, Peter

If you use a gerny, keep it away from your coil pack and other ancillaries, I would hate your next thread to be, pressure washed my engine bay, now car wont start.

Sikaflex or silastic, and car shop sells it. its basically black silicone for cars, stickier and harder to clean off s**t when you screw up. Only need a small tube, nothing drastic. once you remove your tensioner (3 bolts) and your serpentine belt it should become very clear where I am talking about that weeps, degrease that f**k let it soak, get some firm no steel brushes small ones like tooth brush size and have a scrub around, don't go digging at s**t that looks like its ment to be there, you could damage a seal.

We all know seals are for clubbing.

If your still having issues, I'll take some happy snaps and show you.

G'day dc_todd,

Ok, wont use the gerni, what method to clean the engine with would you suggest?

What about can of degreaser and use garden hose to wash it off concentrating around the front.

I've already had coolant go into the alternator also leaking small amount of coolant onto alternator as it is, hose is new , however using old type of hose clamp, the one with a type of spring or flex built into it. Maybe I should change the clamp whilst I'm at it.
