me too,firstly,but mines leaking the most behind the belt tensioner so thats coming out first.
If I have to go to the trouble of pulling all the accessories off,plus the sump,and radiator and unbolt the engine mounts,I may as well remove the engine and do every seal with it on the stand. 240k engine is it worth doing?????????

Nar man dont go to far.I fixed mine.Remove the belt,steeing pump ..do the correct procedure to remove the tensioner then chuck thread locker with silicone on the threads.It will fixit.

Try this first ... trust me.

It might just be your tensioner on the side of the engine.
I makes it look like it leaks from around the front ... it makes a hell of a mess and hard to find the leak usually.

I went on Stav's advice ages ago for this and it sorted it ... fingers crossed it is the same for you.

i was thinking along those lines, i found the idler pulley bolt leaking a little did a remove and refit on the weekend but still tempted to do the works and the front seal on the auto while its out as well.

[waggaclint]

most just leak from the timing cover bolts so if ya just remove em one at a time clean them up and refit them with some sealant on the threads im pretty sure youl be fine hey ill fixed heaps of them doing this also check the chain tension bolt as well they also leak as does the front crank seal...its pretty rare for the actual gasket to be replaced....

[Stav]

Mate ..I degreased mine ..siliconed it and its been fine. Fixing these probs can be a can of darn worms..

[Stav]

what grease did you use?

[V8falcons]

yep,did it on my wagon,any grease is ok I use castrol PD2,or EP2 what ever was in the shed at the time,you just need to lubricate the lips otherwise they will burn/wear prematurely.You need to push the seal back in using the the crank bolt and spacer other wise its abit testing trying to get it started and square.

Are you sure its the front main seal though stav,mine turned out after doing all this to be the timming cover mount screws up the top and the oil was spitting/running down on to the timming casing making it look like it was the front main!!!!!!
If you have your doubts do it any way as I said not a major job in my books anyway.

Ha Ha yeh,mine is about to click over to 250k this week, and I think I better do the fuel pump,as she's missing abit on idle on fuel for a while on gas its fine

[Stav]

I wish it was my timing case.Yep my first leak was my front power steering bolt and it needed alot of silicone to stop it. Next leak..loose timing case bolt.

Tommorow I may have a quick look behind my belt tensioner to see if there is a leak at the timing case. I had the head reinstalled at a dodgey wrecking yard which compromised the engine.It has little leaks which I am sealing slowly.If the car stops...then Il fix it.For now I hate the oil on my driveway.Not much but enough to make my steciling look ugly.

What spacer did you use man?

[V8falcons]

It was about a 60mm 3/4 drive socket,it works perfectly with a long bolt in the from of the crank,dont forget to emery/sand/rough up the groove in the crank from the original oil seal.

I went to fix what I thought was a leaking timing chain tensioner the other day. On the way I found out that a workshop I used to trust had completely stripped the thread on the timing case where the lowest bolt shown goes. Oil was running out when I took the power steering bracket off.





It's the one with all the copper RTV around it BTW! Does anyone know if there is enough metal in the timing case to put a Helicoil in?

[V8falcons]

sly,yep thats the same bolt mine was leaking(one of the times anyway) your drilling into the block there not the case/alluminiun cover if you use a helicoil yes you can do it but DONT drill too far in as you'll drill into to no 1 cyl bore.

[Stav]

Thats where mine leakt. When bolting it in it strips the thread alright.I would be defensive to helicoil as there may be a chance of dropping something into the engine wont it?

[sly]

So if it won't seal properly I'll need a new block... any other options?

err no you repair the thread,replace the timming cover gasket,and seals and o-ring for the chain tensioner.
A little trick I did with where your bolt is leaking is put an o-ring on the bolt with silicone. after you've repaired the thread that is

Hi everyone. Put 60 k/km engine in au, got massive oil leaks! 2 litres in 2 weeks, barely driving also! Just when it gets up top, gonna do the clean, silicone, tensioner o rings, thread locker, I was playing around with old engine today, is it fine, to lock un lock cam tensioner with finger? Mine fits, lol does it sit on the last step not fully removed, in correct position? Why can't you remove outer thread nut without locking full ninety degree as in full lock position, new engine w.a.p.i.t.***! thanks, are not fords fun, like there aren't better ways to enjoy life!

Also I think Whoosha did a photo essay when he did his son's AU - I can't find it. Use the advanced search function.

Doesn't look like a pleasant job, but then what is these days?

Cheers!

My 'how to' stopped my leaks but I wasn't losing anything like 2 litres in 2 weeks. It is a bugger, I was thinking to run some chalk lines in different places to see if I could track were most of the leak was coming from before I found Whoosa how to. You might need to try that at different heights etc to see where your is coming from.
Good luck

Keep in mind that the cam sensor has an o ring on it as well. It will look like a crank seal gone bad. But that amount of oil, may well be the tensioner if the leak is around the front of the engine.

[Rfordsfun]

Thanks all, is timing cover top of tensioner plug and side,right between block and tensioner port, hell of a place! 10 times cleaning and siliconing, fed up sheesh, about to put old engine in! did tensioner Oring, thread tape, silicone vct idler pouring out of their? How does that work ? Odd. Slathered with gasket goo, lol if not working might try metal putty, or remove and fix properly jus my luck ! Should of done it prior! Word from the not so wise 4 litres of oil in my local spots, let alone my drive way <- fords new symbol
