Technical Oil leak engine

[Hharbers]

My 87 panda 1000cc 4x,4 is leaking engine oil. Its leaks where gearbox meets engine.
(I try pointing at it with allen wrench)
It dribbles from there to lowest point of sump pan where it drips on the Floor

What would be most likely causing leak. Crankshaft oil seal or sealing of sump pan?

Sump pan seals replacing is no to big fix to solve on street in front of our house but if my oil seal is blown i have to remove gearbox

Do i need cork seals as in my Haynes manual

In eper and online parts stores just Liquid sealer is Shown instead of a gasket

You can probably remove that thin metal cover, for a better view

These FIRE motors are generally pretty good,

But yes you might have Crankshaft, or even Gearbox shaft seal leaks (oil is quite different)

Oil pan/sump,

You will see how high the oily mess is, when removing that ( 3 x bolt..?). Tin cover

Thanks,
Its engine oil for sure.

It just started to leak a few days ago. I have driven just s few miles since

I have looked with torch light and seams still to be clean inside. I will remove it to have a better look.
Upper bolt is quite hard to reach

I think of its s blown crankcase seal i would suspect it is more wet of oil inside.

Do i need cork seals as shown in my Haynes or just Liquid sealer as is Shown in eper

i done a crankcase recently and mine was instant gasket from a tube. i would suspect its more likely that your crank seal would leak than the crankcase. if so do the crank seal along with the clutch

check the seal around the distributor too. the one on mine had turned as hard as glass and cracked causing a leak. a nice easy repair with any other rubber o ring seal of the same size

Dragonman Thanks, will look at it

Took the gamble and Remove oil sump pan. Sanded and painted it black and installed with siliconeliquid gasket. Looks complete dry again.

now i have an oil leak in a similar place! cant tell if its gearbox or engine cause i put the same oil in both more ivestagtion required.

Gearbox and engine same oil?
Both engine oil 10w40 or both gearbox oil.

When engine oil is more black you will see different if its gearbox or engine leak.

 

[binhoker]

10w40 in both

10w40 in both

No problems with gearbox wear or bad shifting? Why not using recommend oil for gearbox?

ive just rebuilt the gearbox and its shifting great great. the recommended gear oil is expensive and hard to find so ive put some engine oil in to get the car on the road. it works fine.

theres a chap on here (firstcar-y10) who has a gearbox with about 300k miles on it now. it was 250k some years back. he uses EP GL5 spec oil in it and has for years. my 50k 4x4 gearbox is a bugger to get gears in 2nd to 3rd and 3rd to 4th both crash quite hard when shifting. it uses the correct ZC-90 GL-3 spec oil that Fiat use. something i do not think i will ever use again.


i do have a spare 4x4 box that i want to take to a rebuilders. i also want to get a custom cut 5th gear made taller too. i think 5k rpm doing 70mph is a bit poor on the old engine. these FIRE engines give a good amount of low end torque for a petrol, so would be fine for being a bit lower in the rev range.

i removed the gear box and flywheel to check the mainseal turned out that the leak was at the sump joint near the mainseal. the gap is quite wide near either bearing. sump needs generous application of sealant in these areas.
