wtf?!? hole in the engineblock causing oil leakage

[Enzo Molinari]

I finally had a breakthrough with my mysterious oil leak (front side of block, main suspect oil dipstick tube). After removing the oil pan, which wasnt all that fantastic, and the dipstick tube I found a hole in the engine block!!

Its not a damage but a machinedrilled hole that is supposed to be there. Question is what is it for? :S
Standing in front of the car looking at the frontside of the engine block its about 25 mm to the right from the oil dipstick. Machined horizontal, right through the block, coming out rather high in the crankcase. About 11 mm diameter. Ive got pics but I dont know how to post them...

Can anybody tell me what its for?

crank locking pin hole?

Had a cam belt change recently?

 

[Enzo Molinari]

Yes. timing belt was changed just before I bougth the car last week.

Near the gearbox, just above the sump? Crank pin goes in there when the timing belt is done. Bung/screw should be in there now.

I just had another look and that hole aligns perfectly with the crank. There is also a cut out in the crank that would make it possible to lock it with the cyl closest to the gearbox in its top position, through that hole.

It seems that the mechanic forgot to mount a plug in that hole after changing timing belt. Right?

 

[Fred@BTM]

yep correct, go slap him

 

[Enzo Molinari]

Thanx for the picture. Thats the hole and there´s the reason for it. How does the plug look like?
