checking for cracked head or bad head gasket..

-
huh?

eye ball the bolt hole alignment on both sides, it should be easy to tell weather it'll seal or not. Also look at it from the front to look at angle between head intake.
 
Isn't this like your 4th set of intake gaskets? I mentioned before that something (Block, heads or intake) has probably been machined so the surface angles are not correct.

Intake gaskets are not rocket science. If you can't get it right in 4 tries something other than the gaskets is wrong.

the block has been 0 decked...Ive never had water in my oil this bad before.. its under the valve covers and happened recently and the only things I did was change the cam..so front cover and intake...once again if it was head gaskets. I think I would have over heating problems..bubbling of the water in the radiator. which leaves me to believe That Im going to do these intake gaskets 1 last time..with the cork end seals and if i get water in it again...I will pull them motor and change all the gaskets

I think what he's trying to tell you is that gaskets arent gonna do it.
You have a machining issue.

Many times don't get bubbling water in the radiator. That generaly happens when you have a cracked head. If you have done this 4 times based on what I just read I think it might be time to dig deeper into it. If it is a machining issue then you need to find out what you need to replace.
 
well see ive never had the white stuff under my valve cover like I do now...and the only thing i did was change the intake gaskets and front cover..thats all

and I jsut broke my new cam in and when i took the valve covers off there was nothing there, but just the other day i changed the intake gaskets and oil..which is the oil i just drained and now i have the milkly white stuff which is why i think im f$@$ing up
 
im going to drain the block and radiator and pull the intake and if theres water in the valley good chance its intake gaskets right? if its fresh water
 
There will always be water left in the intake because you can't drain it completely so your answer in NO that will not tell you.

You already have water/oil mix in your your whole engine since you stated you found it in the heads. That also means you have water in your oil pump, cam bearings, main bearings and rod bearings. Water can and will ruin the bearings pretty quick.

If all you want to do is replace the intake gaskets then it appears this thread is finished. Hopefully the 5th set of intake gaskets fixes your engine. I haven't read one post telling you that is what you need to do.
 
yes this is my 5th set but all the other times i never seen it look like this before
notice the sitting water and how the gaskets are moist

You need to check that intake allignment & make sure its sitting "true" on the top & bottom of the runners & water jackets, it is NEVER good when coolant runs through the oiling, even breefly it will do damage & shorten the bearings life.
 
ya, i soaked all the water up in the valley and poured the cheap oil in for temp.. im going to do a compression check on it tomorrow and see what the numbers are...if they are good then im going to guess its not a head gasket if there not in the 170-180 range im going to pull the motor.. this cam should have a effective compression if 8.5 my first cam had the same effective compression, so if the cranking numbers are similar im going to assume the head gaskets are fine.
 
Dude this car thing just isnt working for you.
It is excruciating reading your posts.
 
Just trying to help you out dude. You know I would be pissed to after my 5th set of intake gaskets. Im done.Good luck !!!
 
whats that hanging below the gasket in pics?

right below where the heat cross over would be, no cross over on theses heads though.

if they cracked in the runner from a thin spot, you'd see a clean area where the crack is surrounded but an tinted/golden .

the cork seals will do nothing for sealing the water cross over.fyi

After 4 tries I would rtv metal plates over all 4 cross overs [like when when you block the exhaust cross over] bolt down the intake snug [no gaskets] and then after the rtv completely dries...pressure test it again and see what happens.
that way the passages are blocked, so if it leaks it'll be from somewhere else.
 
What happened to the old intake? Where did the new one come from?
 
I'm with Joedust, you need to test fit the intake. Put the gaskets in and lay the intake on and check the end gaps with a feeler gauge. There should be pretty good size gap at the end runners with no cork gasket or rtv.If the gaps aren't there then it would cause sealing issues.

this is my old intake, ive never had a different one

and that little thing hanging down is the tab on top of the head gasket that has the brand on it

do you know how much gap? or what the angle should be on that?
 
I saw this same thing happen on a buddys 396 chevy years ago. I cant remember if it was the intake , heads , or block that had been milled but it was one or the other.
