Head Studs Leaking Need Help

[NOKA72]

Whats Up Guys...put This Motor Together With Head Studs...my First Time Using Them....started The New Engine Today Everything Is Beautiful ...oil Pressure Is Awesome...water Temp Is Good...sounds Great...rock Steady....then I See Water Shooting Out Of The Stud...retorqued That One Because At This Point Im Furious..and I Added The Coolant Tabs And Restarted..i Still See A Lil Seepage Out Of One Maybe Two.....what Can I Do......vinny

Don't feel bad it has happened to many of us.

Try more of the AC Delco tabs. It'll probably work.

Check your oil for coolant, cus the studs under the valve cover can leak too!

If the tabs don't work you'll have to pull the studs out and seal them with something. I use Loc tite hydraulic thread sealant (loc tite 545).

you may get away with it (50/50 chance) if you pull the studs out 1 at a time, seal and retorque them individually, but I wouldn't recommend it. I tried it once but it didn't work. Head gasket blew on the first drive. Filled the crankcase with coolant and graphite. (made a bad situation worse)

If it were my car and the seal tabs didn't do the trick, I'd start pulling the heads back off now.

leaks

did you use any sealant on the studs?

 

[Chuck Leeper]

Moroso ceramic sealer works for me.

 

[Just a Six??]

They need sealer! Locktite 567 Will Not Leak!! Read this article. I have never had a leak & dont use the tabs but I follow these instructions closely.
Good Luck. I guess you could do 1 at a time? never tied it?

I Used Arp Sealer...think Im Going To Try A Retorqe And Then See What Happens...if Not Has Anyone Had Any Luck With Swapping Out With Bolts One At A Time Or Am I Just Dreaming.....thnx

ARP sealer is junk. Permatex high temp thread sealer works great.

 

[Just a Six??]

Few work well. I know from 6 engines that 567 works. I cant say about others but I know some are good & many are not. I would go 1 at a time up to about 65 on all so they are even & then do the final all together at 80-85 or a couple more than what they are now. not much but a few for sure IMO Altho I have never tried it. Just what I would do. Good Luck!

Permatex Ultra-Black RTV works great.

Ultra black is what i used- no problems.

ARP sealer does NOT work, junk. I've used GM Teflon paste, Ultra Blue, Ultra Black and plain ol' black silicone with great results.

head studs

Make sure the threads are very clean !no oil or old sealer in them. thats the key to no leaks
