View Full Version : Broke through an intake port

I just notice that I have a spot that broke through on one of my intake ports, into a head stud. I have a few that have done this on my exhausts and have been told that this is no problem. As long as the stud and nut are tight this should hold everything everything in the engine? Or should put a dab of epoxy over the hole to fill it.
Won't this pump out my manifold pressure? 40 psi?

Decided to make an executive decision and put a layer of JB on the hole and used a greased up stud as a backer. Seems like its going to be ok, just smoothed it with my finger and the port looks pretty much like it used to. Just hope the epoxy stays put for a while.

now that will be a problem for sure. We never epoxy that because the 2 different metals expand and contract differently and it will come off. Most likely in the final round of the biggest race of the year. As long as you run a washer and nut and tighten it up, it is sealed. Nothing can get in or out as long as you keep your fasteners tight! Take the epoxy out, this stuff always seems to fall off. We run all 4 intake ports cut right in half and the stud actually sticks out ½ way with no issues @ all.

Like Bill has,...I've also see this ran successfully with no problems.

Well, I talked to a few other people (on different sites) as well and the general idea is that I should get rid of the epoxy. Then just seal the nut and washer up to the head. I am going to take that advice and cut the epoxy out. Now is the perfect time to do it when the ports are clean.
Thanks again for the info.

Cory,
If you like, over your next tear down ship the heads down and I can sleeve the bolt hols
if you like, .. no charge just pay shipping.
It is true though that it shouldn't give you any problems.

Hey Curtis nice to see you here. Actually I was going to send you the heads after next season anyways to freshen them, so I'll definatly take you up on that offer, and if the heads happen to fall onto your cnc mill (by accident) and they come off with larger ports that flow even better:D:D
I wouldn't say anything
Thanks for posting

Thanks for the welcome back, but really I don't have time to hang on forums, ..

Cory, How about a set of these instead?
go to my web site and look under "RFD Billet"
Joking aside, you should e-mail me how you've been running, ..

That is really all you need to do. I have seen people sleeve the port, does absolutely nothing and kills the port really bad, most people already know this and don't even offer it. It also compromises the port further buy taking again more material out. DON"T do it.
When you need a killer valve job that actually makes power with a blown car, send the heads up if you want and I will give you a 50% discount off a normal real rolled radius valve job. Either way, I would not under any circumstance remove more material than is already gone. Plus, keep in mind, the tube sticks out into the intake port and kills it! We flowed the heads without the tube and with the tube, it was really bad on those 4 ports. We pulled them back out and the port came right back. Being a blown car really does not kill the port as if it were n/a. But still not needed.
