Range EFI 3.9 front cover oil seal

Hi,
Remove the old seal...looks quite good. Any more i put a new one but not seems to be perfectly "watertight".
Finally, I decided to put side to side the 2 seals, in case the new one is not 100% good .
Any suggestions ?

Don't put 2 seals on even if there appears to be room. Assuming there is space end float doesn't kill one, lack of oil will quickly kill the other

Ne mettez pas 2 joints même s'il semble y avoir de la place. En supposant qu'il y ait un flotteur à l'extrémité de l'espace, cela ne tue pas l'un, le manque d'huile tuera rapidement l'autre.

sorry but i don't understand ...end float ?

there is a slight distorsion on the right side of the seal (can see on picture) and the WD40 go through.

End float is the movement of the crank in the block from front of engine to gearbox, there is an allowed slight movement.

Check the end of the crank where it goes through the seal. It could have a groove worn into it. This will let oil pass if it is badly worn.

That will make no difference after a short time.

OK i keep only one on my cover. I put the older one but in good shape.
The inner lip is good as the spring. The outer lip (photo) is a little damaged but it doesn't matter for the seal efficiency...
agree?

Manual says : Press in the oil seal until the plain face is 1.5mm below the gear cover face. Mine is just at the same level as i use a wooden block, and not a press. If i do more i fear to damage the face. Is it important to go 1,5 mm furthur ?

It would be ideal to get into its proper position. Peut-être avec une chasse groupé ? Légèrement...

If the seal is damaged fit a new one.

Seals against the pulley assembly, not the crankshaft.
If there is a groove or other wear on the pulley assembly where the seal seals you have a number of choices.
1. Fit a new pulley - ETC7339 - which are very expensive. Used ones may have the same issue

2. Take yours to an engineering firm & have it built up & reground.

3. Fit a speedisleeve to cover the damaged area. I've used these for the same issue on my 3.5EFi. Take the pulley off, measure for the appropriate sleeve, fit the sleeve to cover the damage, remove the fitting flange on the sleeve & refit the pulley to the crankshaft.

ETA. If you use a speedisleeve you will need an appropriately sized piece of tube to seat it to the required depth as the fitting tool that comes with the sleeve isn't long enough.

Use the wooden block to seat flush.
Make a washer out of 1.5mm steel to fit on the outer part of the seal.
Place on the seal & use the block of wood to further seat the seal.
Remove the block of wood & the washer & it should be OK.
