Hi guys having issue with inlet cam gears leaking, new seals and s/h gears fitted, anyone came on this issue, Iโ€™ve tried 2 types of seals, canโ€™t get leak stopped, itโ€™s running fairly heavy on top of alternator. TIA

Find out for sure where the leak is coming from. I assume you have got the belt covers off to see it running? If it's landing just on the alternator and not going everywhere take a closer look at your oil pump area..

It could be:

1.the oil pump bolts loose at the front.

2.someone pryed on the oil pump when removing the crank pulley & it has a hairline crack.

3. damage/improper installation to any of the cam or crank seals.

4. intake cam gear lip out of round (possibly damaged if you've had them off and reinstalled them).

5.the VTC seals on the front of the gear could be leaking.

6. VTC gear itself could be leaking (At the back!) You can stick a mirror behind it and see if there is oil flinging out the back of the gear to see if its the gear itself without removing it. You can remove the gear and see if backplate rotates & if it does the gear is definitely shot.

No other places it could be leaking & all easily fixable in a few hours

Iโ€™ve figured cam gear is leaking at rear, where itโ€™s machine pressed in, one gear spins at rear one doesnโ€™t, so I figure spinning gear is shotย 

So the gear is at fault.. Your options are:

Have it welded with a very quick and low heat tig weld so it doesent ruin the rubber o ring inside. I can do this for a small fee if you post it to me.ย 

Buy a good used gear

Drop big money on BDE cam gears that fixes the issue by design by putting a dowel pin between the 2 parts that come loose and rotate..

I've got a good used vtc gear i'd be happy to sell for ยฃ50 + your broken gear.ย

Iโ€™ve got 1 gear that does not spin,, do the only leak if the spin?ย 

I've seen them leak from even without being able to rotate it, if you can rotate it then you will definitely need to repair or replace it.ย
