i just replaced the intake gasket on the 3.0, and 3 of the injectors
were physically broken, too. anyway, well, replaced it, idled it for
about 30 minutes, car idled fine, no overheating no leaking ...
then later took it out on the road and coolant spewing out on the left
side by the water pump (the same place it had leaked before)
any idea what it could be?
Assuming you're seeing what you're seeing (with wind blowing over the
engine on the highway run, the leak could actually be anywhere...
radiator, lower hose, water pump, overflow container, heater
Did you follow the Ford steps, especially the first and third ones
below (and did you use new seals):
Apply a 5-6mm (1/4-inch) drop of Silicone Rubber D6AZ-19562-AA or BA
(ESB-M4G92-A and ESE-M4G195-A) or equivalent to intersection of
cylinder block and cylinder head assembly at four corners as shown.
Position intake gaskets onto cylinder heads. Align intake gasket
locking tabs to provisions on cylinder head gaskets as shown.
Install front and rear intake manifold seals as shown. Secure with
Carefully lower intake manifold into position aligning manifold bolt
holes to those in cylinder head. Use care to prevent disturbing rubber
sealer which can cause sealing voids. Install bolts No. one, two,
three and four and hand tighten . Install remaining bolts and tighten
in a two step process. Tighten in numerical sequence to 20-30 N-m
(15-22 lb-ft), then again in sequence to 26-32 N-m (19-24 lb-ft).
Nice when it's relatively easy.
Your other fix may not have been in vain. I've got my 3.0 apart after
non-classic blown head gasket symptoms (lots of white smoke + loss of
coolant, typically pointing to head gasket... but no loss of
compression or power, a real puzzle if it was the head gasket), to
find that I had an intake manifold gasket leak.
