I have a 1999 Ford Expedition. A couple of days ago The engine started losing coolant as soon as the engine cooled. I replaced the coolant only to lose it again when the engine cooled. I was told that it is more likely the intake manifold gaskets leaking. It seems they are right. What is the cost to repair if I take it to a mechanic?
View 1 RepliesI have a 1998 chevy silverado z/71 4x4. I had a water leak and had the intake manifold gaskets replaced. Ever since then, the check engine light comes on and it soots up the o2 sensors and the 4 plugs on the right bank. It may run good for a month or so and then it starts all over again.
View 1 RepliesThe truck we have is a 1999 Chevy Suburban 1500, 2-Wheel Drive with a 350 vortec engine. We replaced the upper and lower intake manifold gaskets with no leaks for about a week and several hundred miles then it started leaking oil and then antifreeze after that.
View 3 RepliesI am about to replace the intake manifold and gaskets. I know all of that process, but first question is if there is anything i should do whilst in there. Second question; what can I do with my intake to get more power? Mainly just kind of wondering before I get my parts ordered.
View 4 RepliesI have a 95 4wd f250 with a 351w my manifold gaskets are leaking I was wondering if when I that the time to remove the manifolds and probably be drilling and tapping should I go with headers if I should where can I get a very cheap set I'm on a budget...

Brake cleaner leak test definitely results in engine rpm change right around "butterfly rod" plug in front of intake manifold near no. 1 cyl. I'm pretty sure that's the problem - the plastic plug blew out. I watched a video showing repair, but it seems lacking.
I do not want to loosen up intake for access - I'd rather remove steering pump and gain some access to plug it up. There still isn't much access but, but eyeballing it, enough to plug, I think.
Three steering pump bolts came out easy. The fourth one is behind fluid line - extremely difficult to access, imo.
Somehow try to remove pump for access to intake hole, or bite the bullet and remove intake manifold for access?
I have a 2006 F150 screw 4.6 auto 116k miles that has evidence of a small coolant leak where the intake manifold joins the head. This is on the drivers side directly under the thermostat housing. The t-stat housing is dry and the hoses all appear dry. It's just wet right at the gasket where the manifold joins the head. Reservoir is still normal so it's not leaking too much just yet.
I searched this site and youtube but didn't find any other posts. Lots of problems with older trucks with composite manifolds but nothing for this one. It looks like a part of the bottom of the manifold is plastic but the entire top and where it is leaking is all aluminum.
It seems odd that this would start in the winter time just driving back and forth to work (no load). And, yes the antifreeze is good. Just wondering if this is a known issue with this truck. Is it just a matter of replacing the gaskets or is there some other flaw I should be concerned about?
If you have a coolant leak at the y hose for the intake manifold and the thermostat, make sure you replace the upper radiator hose as well as the y hose.
View 3 RepliesCoolant spilled on my upper intake manifold. I washed it off to the best of my ability but when i started the car white smoke came from tge exhaust. What my next move should be?
View 3 Replies2.4 Santa Fe ... I just took my Car to MOT inspection and found out there's a leak at my intake manifold and it's coming out of this place. it feels like brake fluid but my brake fluid is full?? I have seen many cars but never seen a part like this before. what is it doing there and why is it leaking ?
View 6 RepliesI have a 94 ranger and all of a sudden it started sputtering, i can hear a vacuum leak behind the intake manifold found what appears to be a pcv valve not hooked up is that the way it's supposed to be?

View 3 RepliesI've currently have 114,000 miles on this Pontiac Bonneville and I replaced the intake manifold last summer. Recently, I have been having issues with the intake manifold leaking a fluid on the right side of it (facing the engine) and been having dirt or some other type of fluid mixing in my fluid tank. The leak has been causing some smoking issues. Also, when I start the car in the morning white smoke comes out of the back of it. Where I need to start so that I can get this fixed. I'm assuming something went wrong in the replacement.
View 6 RepliesI have a 2000 Pontiac Grand Am SE sedan (base model) with a 3.4L engine at 142Kmi that was just diagnosed with an intake manifold coolant leak by an independent shop.
I've done some googling and found that this is a known problem with this engine (including a class action suit). So far the leak is just external; no coolant in the oil and no oil in the coolant.
I've just finished a marathon replacing the y-pipe, and doing the IPR screen. I had many seized/stripped bolts to contend with. 2 I had to cut off in the most awkward places.. Anyways, it all came together and completed the project late tonight...
Befoer even starting the truck I noticed coolant dripping from passenger side manifold/block heater area.. I obviously must have damaged something in my reefing on turbo to get it lined up with exhaust pipes, etc...
I cannot see the source of the leak, but it seems wet above the block heater, but pools there then drips.. I'm curious where to look. Could I have damaged the EGR cooler and its coming from there? At the manifold joint closest to the back, is there coolant flowing there? I am pretty frustrated, because after going through a day like to day, ripping my arms to shreds, straining for 12 hours straight, then having yet another issue to figure out...
Also this is as best as I could get the y-pipe to meet the turbo... slight gap at bottom.
I have a 1995 aero with 4 wheel drive and a 4 liter. Lent it out and the engine was run without coolant. Pretty sure the head gaskets are blown. I found a replacement 4 liter from a 92 explorer and wondered if it would swap in. Will the bolt pattern match, computer, mounts,etc?
View 5 RepliesI have a leak where my heater core tube goes into the intake at the rear pass side of engine. I have read that this part is pressed in. I dont want to remove the intake since i just paid $400 to have a new gasket kit put on. My question is can I bypass this tube with a hose from the water pump like in this video?
FORD 4.6 , 5.4 , 6.8, HEATER HOSE UNDER INTAKE REPLACEMENT THE EASY WAY !!! - YouTube....
If I can do a rubber hose like in the video I was to make sure that the tube just goes through the intake and that it does not supple coolant into the intake??
1999 F-250 LD 5.4... There is a hole on the back of the upper intake manifold, just below the back of the throttle body, is a vacuum hose supposed to be attached here? Have a serious vacuum leak, no coolant loss, no overheating, just had cop's and spark plugs done, now she backfires, stalls and will not stay running, mech. says its an intake gasket but the gasket and lower intake manifold look new.
View 7 RepliesI needed to replace the intake manifold gasket on my 2002 f250 v10. Tore everything apart put the new gasket in which was the same as the old one lyrics to notice something isn't right. I have been driving the truck for over 10 years like this. Is it OK to just continue bolting everything down and go on like this? I am guessing the prior owner 10 plus years ago put the wrong intake on. I keep looking up intakes but they all look just like the one I have. Also that port exposed is on the back passenger side.
View 3 RepliesI have a leak between the metal and the plastic of my water crossover.
Do I need to remove the manifold to replace the gaskets for the crossover and if so looking for a good thread showing how.
Our 2000 explorer xls 4x4 with 4.0 ohv just pop the code for the intake gasket leaking. My question is, would there be any way to tell if it is the upper or lower that is leaking? It has 188k on it but still runs good. I think I can feel a miss in it at idle but it is not a steady miss.
