Rislone liquid copper block seal

[muff34]

has anyone ever used Rislone liquid copper block intake & raditor stop leak in an attempt to seal leaking intake manifold gaskets? Gm 3.4 with 85000 miles.

Stop leak and dope only creates more problems.
If intake is leaking stop leak will not seal the pastic gasket crak out.
Get a FEL-PRO problem solver solid rubber/metal intake gasket set and be done with it.

since you know this is a gasket failure any stop leak will only slow down the leak for a while.. If your coolant system is corroded or has a lot of debris in it from lack of coolant maintenace you could damage the engine .

as the metal expands / contracts this gasket leak will continue to leak ..gasket and the metal mating surface is usually damaged from corrosion.

Did you do any Test's?
Visual Inspect
Coolant pressure test
Smoke test


Symptoms-
Is the coolant reservoir tank contaminated with oil/gas?
Is there coolant in the block?
Is there any shortage of coolant?
Over Heating.

1) Replace any bad rubber hoses, or water pump.
2) Replace Intake gasket if Bad
3) If Radiator, or heater core, I would consider Metallic block seal.
3) If a bad Block, or Head gasket, I would consider http://www.steelseal.com , or blue Devil.

Go to any Auto Parts store, and ask what's the most perffered by mechanics.

If the block, heads, or head gasket is bad, it's worth the try!

Sounds GOOD.
Thanks for posting back the repair.

I used liquid copper Rislone to seal a head because one of the spark plug was showing some water due to a crack in the gasket. It works perfect but i don´t know for how long, some mechanics tells me it would last some 2 or 3 months, others tells me up to one year. The thing is that the first time this momentaneus solutions brough me another problem: a hose stocked and broke because in one corner of it the sealer accumulated and became hard way to the water to circulate.
My car is a Honda Accord 2000 VTEC 4 cil.

I don't know how you are sure it was a gasket issue. if this is a crack/or metal defect causing the leak into the cylinder it should hold. If its a gasket especially on the heads this may not last very long.

using these products the system must be clean. if you have lots of corrosion and mineral deposits from the use of non distilled water these sealer products cause all kinds of coolant retrictions. using too much product all at one time is not recommended.

I never used this product. I have used another product with good results .
