torx sump bolts

[craigus1977]

Heres one for ya.
Does anyone know the size for the sump bolts on a r19 16v? I measured the thread and it comes out 7mm but i'm sure you can't get M7 bolts. Are they a dodgy UNF size? As they also have a fine thread.
Cheers

It's French, they won't be anything other than metric

Thought so. Cheers dude

Lots of M7 bolts on them, despite my friendly engineering supply shop telling me they don't exist

I have a feeling those bolts are unusual too. iirc the exact same bolts on the megane 2.0 are 'E' type, which is the opposite of torx. Much less prone to rounding off although not always so easy to get the socket into some of those around the sump.

Those sump bolts are a pain in the arse, seem to be made of cheese and the torx bit chews out of them so easy. You'll probably have to chisel a few of them round.

teh secret is use a pick to remove any crud from the hole, use a decent torx socket, belt it with a hammer then undo it without leaning the ratchet etc over.
