sump bolts torque!!!
Hi All,
Have now changed my sump gasket twice now and I seem to be doing something wrong as it still leaks oil. Can you over tighten the bolts that makes the
gasket thin like paper and then disintegrates..I can't find my Ford Pinto engine book for love or money.....so how tight must the sump bolts
be....
regards
TimR

You can overtighten the sump which would have the effect you describe.
I would use some silicone gasket along with the cork gasket (and not overtighten) to achieve a seal.
Just a thought - the sump isn't distorted around the flange at all is it?
Cheers

are you following the correct sequence?
tighten the bolts either side of the main bearings first (make sure you also use sealant there too) then just work your way from side to side. Hand
tight with a spanner is the required torque, the bolts will snap if you go crazy and are a right sod to sort out.

A tip I heard was to apply sealant all round the gasket and then tighten all the bolts hand tight and leave the sealant to set. When set then tighten
the bolts to the correct torque. I've not tried it but sounds like it should work especially if the sump is slightly distorted.

thanks guys, I have already tried the sealant approach, but did not wait over night. I have done it this time and will check the bolts again
tonight.

have you checked the face of the sump? if it is distored it leaks and is caused by over tightening.
use a flat surface e,g, sheet of glass to check and dress it with hammer.
with cork gasket, it doesn't need much tightening. finger tight then about 1/2 a turn.

Burtons do a competition gasket for the x flow , they may do one for a Pinto ? Have used one on my xflow since the car has been on the road and reused
it when the engine was rebuilt with no leaks
