oil leak sealer

[lincolnsix]

I have a leaky gasket between the non overdrive gearbox/rear extension on my GT6,  the oil was 

 

changed approx 2000 miles ago and is still very clean.

 

Are there any risks in using a reputable brand leak sealer?

 

      Thanks for any advice,            John

its possible to remove the tail housing  with gearbox in the car

 

need to  drain oil  remove prop and coupling , undo the cotton reel mounts , jack  the box  up a little remove speedo cable and undo the housing , remove clean reseal and refit.

 

i have no experience of oil leak sealer additives

Thanks Pete,          I was banking that it was an inside job.

You may no get the hsg right off , due to things like prop tunnel getting in the way

depends how high you can lift the gearbox without rad hose stretch etc.

 

certainly enough to clean dry and add some decent sealer

Leak sealers i.e. the ones you pour into the oil were originally designed to swell leather seals (or cork gaskets?) so the the leak stopped... don't think they have any effect on modern seals. You can get the ones like a crayon which you rub into the joint and they might work at this point... I think Frost sell them? 

(they do... just checked)

leak sealer wont wuk on Gaskets,

it,ll doo its job on rubber type seals, as it meks,m swell up.

 

if yer gonna get it off, use a silicon sealant, or a Loctite type stuff  574 is v v good

butt, the flanges gotta be v v clean.

 

the Pen type, its like a  grey waxy candle

it wuks for a short time, then fails

 

If, yer after a DIY approach, then if ye can identify where its actually leakin frae,

then clean it all off, an seal it on oot side wid a sealant,

butt,its gotta be spotlessly clean,or silicon sealant wont stick
