I Have An Hole In My Block...

[Guest Sonny]

Hi

 

Yesterday after starting the engine, and leaving it idling for a few seconds, i've noticed that the antifreeze started coming out of the engine's block!

 

 

It's on the back of the block, on the side of the gearbox..

It looks like it's been corroded...

 

Any suggestions to solve this?

 

Thanks in advance.

 

Regards

Well it is unlikely to break a block given the warm weather so I'd go looking at all your coolant pipes first.

Thermostat Housing and numerous coolant pipes are above/around that area, as Rob said check for leaks there first. The only place where block leak water (if they haven't frozen) is out of the core plugs.

 

Cheers...

yes they can corrode through and leak, ive seen it twice now.

Guys, the coolant leak is through an hole in the block, that can be seen on the picture. It's around 5mm wide...

 

Can it be welded?

You could try liquid metalling it but it's not exactly an ideal solution really. I had this problem but decided it wasn't really worth the risk in the long term so replaced the engine

Well, I have a spare 180A 1.6 105bhp engine, and it is running. Maybe I'll use its cilinder block...

Don't see why patching is a problem, as long as the patch is good enough to withstand water pressure. I've seen thermostat housings held together with araldite with no problem at all.

or if you can get at it

 

drill it out , tap it and plug it
