well it seems im going to get to work on porting my heads sooner than i expected. thats actualy not a good thing. heres the story. i was driving home from work the other day car was runnning like a champ when i noticed my heat rising fast and my fan didnt turn on yet so i stopped home to see why.`````i then squeezed my radiator hose and there was no fluid in it. well i went to get my hose and fill it up when it struck me. there was no way it leaked coolant between yesterday and today and definatly not that much so i looked for leaks and nothin. i then proceeded to check my oil and just as i thought its as grey as can be and milky.. so my question is what happened all of the sudden? it runs the same and runs fine so my guess is intake gasket i hope.whats yours?

 

Could be intake gasket, head gasket, or a cracked block, intake manifold, or head. Either way, get that oil and water out fast.

 

If you're blowing clouds of white smoke out the tail pipe, then you cracked a head.
Like Trickster said, it could be a host of other problems as well... with the least expensive being one of the gaskets (intake and/or head).

 

billowing white smoke can be the head gasket to, have had it happen before.

Milky oil BAD. Def means you're coolant mixed with your oil. Trickster has the causes down.

 

Compression / leak down test.

 

if you dont have coolant stains on your block then it is not the intake manifold gasket it is your head gasket the coolant is leaking into your cylinders and is mixing with your oil.

 

Please don't tell me you are going to post that in every post.

 

Mind explaining that one? If the intake gasket blew on the underside, in the valley, then it would suck right into the valley and drain into the oil. How the hell does this 'stain the block'?!? How would it get outside of the block? What if the block itself cracked? Head gasket then?!? Intake crack in the valley? Where is the 'stain'?!?

Dammit, if your going to post mis-information go here <A HREF="https://www.thirdgen.org/techbb2/search.php?s="><IMG SRC="https://www.thirdgen.org/techbb2/images/smilies/search.gif" BORDER="0"></A> and get something mildly entertaining at least. (BTW that is clickable - Some steakman dude did it.) And I think everyone here, including the original poster, figured out his coolant mixed with his oil.

Oh yea, lose that dumb sig pic. It's obnoxious.

And as Steakman mentioned compression, leakdown as well as a coolant pressure test will help pinpoint it.

 

i ruled that out because it runs excellent the running condition never changed.not even a misfire.


i think it just leaking inside the lifter vally not external.

i rulled the mixing antifreez in the cyl out because it hasnt ran different or smoked more than the usual slight puff if i open the secondarys.


hope its not block head or manifold.im changing the oil in a few.

my reason for thinking its the intake gasket is because it happened all the sudden. i drove less than 1 1/2 miles and it happened out of nowere before the engine was to full running temp. i dont see how a iron head or block could just all the sudden crack with less than normal heat.i guess thats my theory of an intake gasket prob.anyways if my block is still good i guess this gives me reason to change my cam port my heads and swap to lt1 intake. i just wished it would have come another way.

thanks guys all your sugestions are appreciated.

 

ok finaly got it ripped apart. looks to be the back driverside intake gasket is leaking rather bad. the whole entire lifter area is filled with that milky oil residue. i think the intake is the wrong year for my old heads. the 4 corner bolts dont line up as well as they should. i dont understand why i didnt notice this when i put it on tho. it seems like they are putting pressure on the intake trying to lift up on it.

 

ok scratch that for some reason it looks like the whole drivers side wont line up. the passenger side is good but the threads on the heads are higher than the holes on the intake on the driverside. im gonna elongate the holes a little on both side and then see if i can get it to sit flat again.

 

That would not be a good idea, if anything it will only make matters worse in the long run.

 

have you had the heads milled ??? if so it may have been enough to narrow the space between the heads ... ive had lots of heads milled and never had to deck the block but ive been told that it is a good idea ... keeps every thing lined up correctly... tao

 

yes the head were milled. the thing i dont understand is that it didnt go on that way the first time otherwise i wouldnt have put it on. i put the intake back on today and flushed the oil with motor flush twice. im gonna flush it again tomorow. it seems to run good other than a valve cover leaking on my headers.no more water in the oil yet either.

 

cool ... hope you got it ... i was wrong on my last post i should have said the intake should be milled not the block ... i relized what i typed 2 hours later on my way home lol no clue what i was thinking ... good luck ... tao
