Yet another new post from me.. Hi guys

After replacing the gearbox and in the process cracking the sump..
Trying to get it splined on using a bolt across from gearbox to the sump which was rather stupid I was hoping it would pull it in a bit.
On the splines I mean, with gearbox on I then had to replace the sump.
However with the gearbox on not realising there are two smaller bolts that are Unreachable without removing box,
I did get it undone, the sump.. Don't ask how the sump had to be made into smaller pieces shall we say.
Hoping the pressure from all the other bolts might suffice and the rtv gasket upon refitting new sump... Said to smaller bolts were left out
I filled engine with new oil.. Other was already black after just running a short while, then finding release bearing snapped on lugs.
I considered it a flush.. Started it and it's pissing oil out..
I had a feeling I should of changed main seal but found the flywheel rock solid to undo..
I don't see that the oil is from sump and with inspection doesn't appear to be any around missing two bolts.. I know it's not ideal but didn't want box of again..

I would say it must be the main seal.. It's at a state of coming out fast.. Not even up to temperature..
Which assumes it's under pressure, its had some of that seal replenishment stuff in before I cracked sump and replaced with fresh oil.

No oil is in gearbox so nothing to do with that.

Joyfully another new bit to go on and gearbox of I think for the third time as the release bearing that came with a stage 2 clutch was made partly of plastic SNAPPED .. Was replaced for a metal one, I think it was a Valeo part as a a friend had same issue..
So now my new clutch is probably soaked in oil.

I know seal replenishment will be no good on that particular seal and box will be of again..


Questions are getting the dmf of it as the flywheel just turns the engine how to lock it down to get at the seal and refitting seal tips..
I believe a smear of rtv is beneficial around the odd shaped seal..
It is a odd shaped thing and eBay has an fai
Made one for £20.29

If anyone knows of somewhere cheaper or if they think fai is good enough please chime in.

As always thanks In advance..
Ain't life a bitch...

Also if any other ideas for what fault is possibilities,
its coming from between bell housing and block.. Oil I put in was 5w40 and it's far to fast a leak to be helped with thicker stuff.

Long post I know just trying to detail
Oh and of course mk2 punto 2002 1.9 jtd.
And to note this is just sat on axle stands..
Hasn't been driven and yes dip stick is back in with rubber seal and a touch of red hermitite red for good measure

I posted this in tech part also I hope this isn't classed a double posting just wanting some advice.
Cheers, Josh.

Trying to figure this out??? Are you saying you broke the sump tightening the bell housing bolts up? HOW? Are you sure you haven't cracked a piece of the engine block while forcing the gearbox back on?. Sounds like a box off job and start checking.:eek:

Aye, I struggled to make head or tail of this myself!:confused:

Basically sump and and clutch and gearbox have been fitted, two small bolts sit where you cannot get to them to put them in
"on the sump" as the flywheel is in the way...
I'm quite sure the lack of these two smaller bolts isn't the issue...
Having just pulled the box off oil is on the flywheel...
Suggesting it is the main crank case seal.

The only reason for fitting the sump was through my ignorance of using a bolt across from the sump "alloy to try to pulling box back on, pretty stupid.

You'll have to take off flywheel then, amazing how it wasn't leaking before and it is now. Is there oil on the back of the flywheel (Engine side)?

Yeah well it seems odd but inside the old box was a bit black and sludgy... No drip though... Was going to do it then but flywheel bolts are a pig....
Do you know if they are left hand thread..
Or is that the crank itself..

Cheers digger ?

Oh I had flushed it with some new oil first so maybe it dislodged some crud.


Now it has 5w40 fully synthetic... They do say it cleans your engine up better lol

there is a seal behind flywheel, they rarely leak

Cheers but because I had slight trouble removing the cracked sump..
Not knowing two bolts were tucked behind the flywheel, we've had it all in bits again..
Flywheel off, it's had a gearbox change and the old one was black and cruddy inside.
Was gonna do the seal then but couldn't figure how to lock flywheel anyhow..
Back of flywheel was oily and visible drip from the seal.
As it happens the two bolts I couldn't get at go into the bottom of crankshaft seal.. As it has a metal housing.

I will put my hands up and say I may well of disturbed that seal getting old sump off.

Maybe I should just use mechanics lol..
No I've done a bit in my time.


Note to anyone I managed to lock my flywheel with a crow bar getting purchase on a bolt inserted into the gearbox mounting holes on the block..
Surprisingly easy to undo then..
Will be applying thread lock sealant to flywheel bolts and get it torqued up, think it's 160nm
Il look it up though..

And no it didn't damage the crankshaft teeth was careful.

Cheers guys.
