Engine Sealer

My son-in-law is having A problem with some porosity in the cylinder head. He had to opne the holes for the pushrods and hes got a small leak and we can see some steam coming out the Rocker Cover vent.

He put some Barr's Copper stop leak and that didn't do nothing.
Is there something better he can try?

Also somebody said try some Water Glass Sealer . I read on the net its used for concrete sealing. ANybody have any experience with this???


Thanks Tore

I used sodium silicate "water glass" to seal porosity in my A460 block cylinder wall. It appears to have done the job. Depending on how large the hole is, this may also be a solution for you. You can buy it at your local pharmacy. There are some epoxies available if water glass will not work for your application. Devcon makes several. Here's a link to sodium silicate.

I bought a quart, poured almost all of it in the block. This was a bare block. I believe we sealed it up with torque plates and made block-offs for the water pump holes and then pressurized it. We then rotated the block on the engine stand several times. Sorry can't really remember all the details, it was a few years and brain cells ago. Very Happy I would take Lem's advice.

Ceramic Seal should also work. Check your local dirt track supplier, they run it in most of the all aluminum deals that are hard to keep sealed up.
