I had to do exactly as Charlie said to get mine to seal. My heads and block were right, but found that when I put the used intake I bought someone had tightened it to the point of warping the intake around the mounting holes. Put in the resurface machine to smooth it back out, but felt it wasn't going to give a good seal with just the gasket. A thin smear across both sides of the gasket and all is well Very Happy

You know, just as sure as the world is round, that's how my intake was fitting in the beginning when i sat it on with out the gaskets. Ive had it milled and back on but still seeps. After milling it did fit better without the gasket but now i remember it it didnt sit down in the vee good. Dam thing had some rocking to it and was really ugly before the mill job. If it dont seal this time its going to a differant machine shop. This is really F-ed up. Anyway im redoing it today. I got the new gaskets in.
Thanks

I took the intake off today and cleaned up everything good. I sat it on without the gaskets and there was no rock and both sides sat flat with no space but the ends did have their gaps. Looks like its gonna seal. I put sealer around both sides of the gasket and you gotta have your ducks in a row with this ta31 stuff. I'll know tomorrow when i cranker up.
Thanks

There has gotta be something wrong with this intake. I swear I have done 5 gasket jobs and still the same problem. God knows I hate to back track but I don't have a choice. It's gonna cost me but I will find the sourse of the cause. This really suck. Heads, intake and block were all brand new and everything in it. Im gonna see if trick flow will check the heads and intake. Any thoughts on what the cause may be. I don't think any is going to the valley cause the oil still looks new or it may be hard to tell when the oil is new.
Thanks for any and all info.

What gaskets are you using? If they are the repackaged ones from Trick Flow (made by FelPro) then they may be too thin with all the issues you are having. You've talked about milling .020 off the heads, but didn't say if the block has been cut down. I know Lem and a few other venders here can get you the thicker gaskets, so that might be worth a try.

I have tried the 1/16 two times, milled intake and did the 1/16's again then did the 1/8's and just had cometic to make some.031 and still the same thing and I have done atleast 20 engines and never a issue like this. As for the block, it got square decked. I didn't ask for any certain amount to be taken off.
Thanks for any and all info.

Do you think its a good idea to pull the bolt up and crank it to see if I can see how the water is getting in? Im using a manual pump so I would have to cranl it to get water to flow.
Thanks

Put a $59 Moroso electric water pump motor on that baby with the cogged belt and spin the water pump without cranking it.

That's just what im gonna do. Do you think its ok to screw the bolt up? It the bottom front. Or would the intake crack if I do?
Thanks

Something is NOT correct ,that's for sure. Intakes(especially w/everything new) are not hard to seal.

Porosity

Post  460pulling on September 25th 2013, 8:42 am

It seems odd that it is leaking with sealer on each side of the gaskets. I would be curious to see if porosity is causing this from either the heads or intake. Just a thought.

I was lookin at my intake today and might have found what is causing your water to come up through the front bolt hole. The water jacket opening on a A460 intake is at the bottom of the intake flange where it meets the head. The front bolt hole is really close to the water neck opening.So if there's a crack or porosity issue in the intake where the neck bolts up,the water WILL enter the front hole and come straight out the top. Something to check.

Here I go again after a pressure test. My point of view shows porosity. About 7 spots in the local area have tiny little bubbles about half way down and all around the temp gauge housing and at the circumference of the bolt hole. Im fixin to see if I can post these two videos. $350, 5 headaches, almost put it up for sale, cried to yall and the problem is auctually in plain view. Maybe I haven't really cried yet but anyway I gotta see if I can get these videos on.
Lem, thanks for returning my call and your idea was the same as Trick Flow, ''The Pressure Test'' and it worked. I never thought the cause would be there.This is some thick stuff. For sure I don't think its something I did. I cant pierce a bunch of tiny tiny holes through this stuff. Either way it goes, thanks to everyone.

I pulled the intake today and dam, I thought it wasn't gonna let loose. I gently tapped a little bit of flat head in and some wd40 along the top edges and it let loose. Got it shipped of as well. Hope they will tend to it. TA31 aint no joke.
Thanks

They should send you a new intake imo,if it's a porosity issue.

Now that I got the intake off I see there's a liquid sitting on top of the intake valves. It don't know if its gas or oil. Im fixin to post a pic. The stuff is greenish looking.
