Re: Core Plugs installed (w/pictures!)
That's a drag.....
Some engine rebuilders have this pellet they throw inside the core
before putting the core plugs in. Apparently it is some type of super
leak stop to make up for shoddy workmanship.... They are supposed to
'know' how to do the job without leaks, but with the workers they
hire....
Maybe go to a machine shop and ask about it. I think I would take my
heater core out of the circuit before using the junk though.

Re: Core Plugs installed (w/pictures!)
I did, but maybe not good enough - and I used permatex sealant. The
plugs held at 20 psi (the pressure recommended on the tester to test a
system that has a 16 psi cap), but they leaked - not heavily, just a
trickle.

Re: Core Plugs installed (w/pictures!)
I got a laugh from this: "to make up for shoddy workmanship..." I
suppose it's possible that the place I take it to "could" do this too.
I think I'm happier knowing that it will have some warranty if they
blow again - though I doubt they will if a specialty shop checks
everything. And besides, at the 20 psi testing pressure I noticed a
very small air leak around the passenger-side radiator end cap. I
didn't see any coolant leaking, but definately heard a hiss.
Who knows, maybe at 16 psi they won't leak and the radiator won't hiss,
but I don't want to take the chance of loosing another plug with a hot
engine at high revs on a freeway 25 miles from my home while passing a
slower vehicle!

Re: Core Plugs installed (w/pictures!)
Damn man, your luck just isn't running well for you.
That radiator is blown at the seam. Unfortunately if it is the plastic
sucker, it isn't repairable. It is a gasket that normally lets go.
Planned obsolescence at it's best. If it is a metal rad, you can take
it off, clean it well and fix it using plumbers solder and acid flux.
This works well.
