Intake or Head Gasket

Intake or Head Gasket

Postby trendkiller [OP] » May 6th 2008, 6:46am

One or the other is shot. This is on my 94 Safari with just 60k on the rebuild. Trying to figure out which one it is. I have no coolent in the oil, lots of white smoke, and a "Miss" at low speed, or idle. the miss disappears under heavy load or highway speeds. I have coolent running down the side of the block. I have to get in there with a mirror or something to see if its coming from the head/block mating area, or if its running down from the intake. Sounds like a head gasket to me, but if coolent is in the combustion chamber, shouldnt I start seeing milk in my oil?

If it turns out to be the head gasket, is it a problem with only replacing the bad side, or should I do the other one too while I have the intake pulled?
recommendation on head and intake gaskets ? fel pro ok?


thanks for any help in advance.

Hi trendkiller
Is this still under warranty? I wouldn't mess with it to much if it is. The "usual" rule of thumb, if the coolant is running down the front or back of the motor from the top, then it's Intake manifold. If the coolant is running down the middle of the block, it's either a frost plug or head gasket, you will have to get right in their and make sure with a flash light or light of some kind to make certain.
When it comes to head gaskets failing, their is a whole host of scenarios that can occur, it depends on the location of the gasket failure. You can have coolant blowing out the exhaust and not have any or very little show up in the oil. Either way it needs to be taken care of soon. If it's still under warranty then let them deal with it, it shouldn't have failed at all (Intake or Head Gasket) if that's what the problem is . Hope this helps.

Do both head gaskets at the same time. Very little extra cost to do the other one now.

Im pretty sure its my head gasket. My Rad is pressurized even after sitting over night. No its not under warranty. I have the capabilities to do the job myself. However, with finals 2 weeks away, a full time job...etc I have very little time. Im hoping I can at least drive it around for a week before I tear into it. If not, then im screwed. :banghead: :banghead: After some lunch, Ill pull the dog house off and take a look in there.

How Ironic.... Ive been driving around down a cylinder these past 2 weeks and on my way home from my last final at school the head gasket decided to let go the rest of the way. I have CLOOMS of white smoke on acceleration, complete mis fire at all engine speeds and a coolent leak when engine is hot. I am almost certain it is the head gasket and not the intake gasket. Im pretty sure its the passenger side, when I pull the plugs I will find out for sure. I will probably only replace the bad side if its the passenger side as I dont want to mess with the A/C system on the drivers side.

What I need now is a recommendation on what gaskets to use and any tips on swaping gaskets with the motor in the van. I have 4 days off next week and I should be able to limp to my buddy's garage to wrench on it.

Felpro should do just fine it may help to cut 2 longer bolt the same diameter as you head bolts to hold the gasket in pace so it doesnt shift while you slide the head on. If not a helper is a must it is hard to place the head just waire you want it. You will probably want to use the car was to rinse dwn the engine and the comartment around that side.
Hope it helps!

Look on the bright side, if you have to do a head gasket then you certainly will have new intake gaskets too :D
I did my intake gaskets last year, thank goodness I didn't have to do a head gasket. (I knew it was a leaking intake gasket ).

If you have all the top end apart and have to move the a/c compressor forwards to get the intake manifold bolts out, then won't the drivers side head be easy to get off anyway?....just peace of mind to know the head gaskets were both done.

It's likely too late but you also need to check the head for warpage while you have it out. If the head's warped and you don't get it milled flat the replacement will soon blow.

Its not to late... the van has been sitting until I get time to wrench on it. Im going to try some justice brother head gasket repair and see if that fixes it for the time being. Need to get this thing to my parents house where most of my tools and such are. Some 300 miles away =(
