Just got my new motor running and there is water seaping up around the head studs. Is this normal? There dosen't appear to be any water in the oil and everything else checks out ok. Thought I would just put so stop leak or some type of cooling system sealer in there and see how it does? Any thoughts???

We had a problem with this about 2 years ago with studs, I think it was that the studs did not get enough sealer on them. I think we just bought good arp head bolts for them after a while of fighting the problem.

I've seen this with the bolts on the corners often. Use some teflon tape and see if that helps.

Use white teflon thread paste and coat the threads top to bottom after you run a tap down the offending holes. just lightly snug the stud then torque as normal. if it leaks after that just watch it after a few heat cycles it will seal up.

I have had the same experience with leaking studs. Have used liquid teflon, block sealer, and this last time used black silicon on the threads. Using black silicon is the first time I have never had a leak.

Thank guys I will try the teflon if the cooling system sealer and conditioner dosen't work. Like Mickey said it appears to be mainly the front two studs.

I personally wouldn't even mess with the teflon sealer, use silicone. Also, the only block sealer to use is the MOROSO ceramic stuff.

Where can I get the Moroso sealer? Would any auto parts store have it, or is it a performance parts item? Just asking cause I have never seen it.

Those corners have the water jackets right there, make sure you check your back ones too since they are set up the same as the fronts. You might not of noticed that they are leaking since they are in the rear.

You should be fine with the teflon tape, if you would like some added security use the silicon too. I did that on some vortechs that were redrilled for an older style intake and it worked great. I used a washer with the bolt, coated the bolt hole before stick the bolt in and it held. Still used the teflon tape too.

You should be able to find it at your local race shop.

This is the only thing my engine builder recommended me to use for my engine at the beginning of the year. I had two questionable valve seats on the heads when it was assembled. After running it for awhile I had some water pooled up when I removed the valve cover.

So I flushed the system (had antifreeze in the system since it was still in the 30s) and tried this Sealer. 6 races on it with no leaks. The place I bought the sealer from said he sold the **** out of this stuff. He mentioned that many guys run this stuff through their brand new engines at first just to seal up any possible leaks. Who knows?

DONíT USE WITH ANTIFREEZE!
