HG stop leak recommendations?

[Zed Head]

Have you tried retorquing the head bolts?  Won't hurt unless you break one.  Is it the original engine?

Might be that the original gasket material just shrinks, degrades, and leaks after so many heat cycles.  It's some kind of organic material.  Mine looked fine after took the head off, except for the leaky spot.  The metal cylinder seals were fine.

I am afraid to re-torque the bolts. Last thing I need is to break a bolt.

Have already used them twice. So if I replace the head gasket I'll need new head bolts.  Had the head off in 96. It did get a new head gasket then. Forgot those details. You can say I have CRS lately.

It is the original engine

Years ago I used a silver powdery stop leak that worked very well.

That might be the Bars leak head gasket repair I've just looked at. I might try it.

Here's the permanent stuff that hardens, and one of the the silver powders (aluminum dust).  There's a bunch.  Don't forget the raw egg fix.

Or my Dad's favorite black pepper.

Me and Zed's plus some salt and you'd have a Contnetinal Breakfast. Fill your radiator with bloody mary mix, windshield washer tank with vodka and you welcome at my house anytime.

Cook some ribeyes on the manifold...

Party over heaaaar!
