Title: Beastie water leak.
Post by: Amigo on 13 March 2011, 18:28:17
Had a look today & the leak appears to coming from a bunch of hoses that go into the back of the block just above the bell housing. However we can't pinpoint exactly which hose is the culprit. Should we drop the gearbox as it blocks all view?
  There are so many pipes & hoses & this is the first time we've had a go at anything other than servicing brakes, wishbones etc.
    She's in the workshop now & will stay there until done as i don't want to keep running her on water only with no coolant. If it helps she seems to leak the same whether hot or cold & still pressures up.

   Cheers, Guy. :y

Sounds like the HBV Guy. Take the wipers and scuttle off if you want btter access. If you take the plenum off its very accessible.
Much easier than dropping the box out. :y

Remove scuttle and pressure test the system. Mouth to coolant bottle neck and blow will probably do the trick while an assistant spots the leak if equipment not available.(and you dont mind the taste of coolant  ;) )

May need to remove plenum, then inlet/injectors and plastic wedge to view the v if nothing found, but sounds like scuttle off and blow will find the leak.

If it's hbv, scuttle off and run the engine, if no sign play with ac on or off.

Gut feelings are:

HBV
hose from HBV to coolant bridge
Oil cooler plate and/or stat weeping badly
If 1998, car, HG leaking from coolant jacket at the back corner of No6

As others say, plenum off (actually, folded forward to keep coolant system closed, inlets out, and pressure the coolant to about 6PSI (easy way is a modified coolant cap with a shrieder valve, and a bike pump)

Does that mean it's the head & if we take the injectors & inlet out do we need new gaskets to refit or is it o rings like the plenum chambers?
   Really need advice in schoolboy terms please!!!

Pretty much everything I've said for that investigation needs no parts.

The red gaskets each side of the plastic divider plate are reusable 99.9% of the time.  The O rings under the plenum are generally reusable if they haven't gone hard (ooo-eeerr missus).


Put a sheet of kitchen roll in each inlet hole as you keep moving down the inlet system to prevent things falling into cylinders!

No need to take heads off, just inlet gubbins so you can see what your doing. Its very easy as long as you have basic tools. :y
Guessing that Amigo's toolset is more for old Fords, in which case, he will need torx stuff

(Sorry if I'm wrong Amigo)
