Water Cap Thingy
irvined - 1/5/06 at 07:52 AM

So,

I started up the car last ight, and about 5 minutes later it dumped its water.

Its a 1300 XFLow, and the little cap on the block about 1.5" wide which is around half way up the cylinder has come out, the other ones are ok, but its come right out, I've never seen this happen naturally before.

Any idea whats gone wrong, and what do i need to do to put it back in again?

Cheers

sounds like a core plug has come out take it to a local motor factors and they should be able to match up a new one refit new one into block using some thread/bush lock they dont normally come out once fitted though

More common for them to rust through on old engines. If its not at all rusty, it may be that it's been replaced in recent history and not pushed in properlt, they are a tight hammer fit.

Great,

I'll nip down to my local factors and get some thread lock, the one which came out looks pretty rusty so hopefully its nothing nasty

Cheers

Er...

If one is rusty then they probably all are.

You should seriously consider changing them all, just in case one lets go somewhere really inconvenient. It's not a difficult job, just a matter of knowing the technique, and taking a bit of care. The parts are cheap, too. The downside is that one of them requires removal of the gearbox - and possibly the flywheel.

I know it's a total PITA, but you'll regret it otherwise...

I had the core plug on the back of the pinto block (covered by bell housing) fail. Temp repair until i take engine out was to seal it with e metal. It has been fine for 1000 miles. If you can replace then do so ans i suggest you do all of the others as a precaution.

Im sure ive seen people with race engines lock these in place.

Yes you can lock them in using 2 bolts and large washers. It means drilling and tapping 2 holes around each core plug. But nothing too drastic.

pretty sure I've seen somewhere copper or brass core plugs - never need to worry about them rusting .....

RIght, well changed the ones i can get into.

Was fairly trivial, no more leaks, just need to work out why the cooling isnt so cool.
