Guys.

I found a leakage at the timing cover front seal and when I pulled the crankshaft pulley (harmonic balancer) it look excessive worn down to me, and I think this is the cause of the leakage. What do you guys recommend me to do?

Have someone used the speedy sleeve from SOR?

Its better to find an used Harmonic Balancer? mine has 3 grooves because I have factory PS and AC.

There is a direct replacement?

Yikes. You can speedi sleeve that but in your case it may be too far gone. That is usually the result of a mis-set timing chain cover and/or improperly installed front seal.

I think you could fill the grooves with JB Weld, sand smooth then install a Speedi sleeve over that and it would likely hold for many years. The JB Weld would support the sleeve where the grooves are. Just the sleeve alone is not likely strong enough to bridge the gap for long.

www.rockauto.com has balancers too. Not sure how their price compares though.

My guess is no. Too hot to not mess it up. They are cast or forged carbon steel?
Yeah, I don't know. It would be interesting to see. I have always been curious about saving machine parts like that. As many trucks as I have worked on my experience with machine shops and machining is very limited.
