Anti freeze leak :(

So on my last ride with my stang she started running on 7 I got home parked it and found antifreeze in my 8th spark plug. Is that a head gasket leak or what could it be? Ps it's a new motor with only 15000kms I'm so mad right now I had money saved for performance parts and paint but now I feel like this could cost me. Any help would be appreciated thanks!!!

Unfortunately that sounds like a head gasket leak. Luckily if your partial to wrenching, a new set isn't very expensive and if you did the work yourself you could still tackle the mod list.

You stated you "...found antifreeze in my 8th spark plug."?

Did you remove the plug and find coolant actually on the tip of the plug; or find coolant in the plug well?

The it not a blown head gasket, the intake manifold gasket is likely leaking, or the manifold is cracked. Just to be sure, cylinder #8 is on the driver's side near the firewall--is that the one in question?



I ask because it is not uncommon for the #4 plug well to fill up with coolant when the heater core nipple or hose is cracked, or if the clamp is bad...

You look at it and see it if the nipple and/or hose are leaking. It is right by the #4 plug...

It depends on what is wrong with it. If the nipple is cracked there is no real solution other than replace the intake manifold, if the hose is cracked it might have to be replaced or cut-back a bit. Or it might just be that the clamp is loose, improperly installed, or not even there...

If its the farthest one on the passenger then its #7 cylinder and more than likely its the hose goin from the manifold to the heater. Its a usual thing that commonly breaks on the intake mani.

It's kind of buried in there, but it's the only hose coming vertically out of the intake manifold in that area.

The stock manifold performs as well as or better than any of the cheap rip-off aluminum manifolds available on eBay--so it you buy a shiny one get it from one of the name-brand aftermarket vendors.

You can get the FRPP PI intake from a number of online vendors for $240, with many offering free shipping...

Intake manifold replacing in my opinion is a breeze. Just make sure nothing gets inside the heads while u have the intake off and ull be fine

Cylinders 1, 2, 3, and 4 (bank 1) are front-to-back on the passenger side; 5, 6, 7 and 8 (bank 2) are front-to-back on the driver's side--as in the diagram I posted above...

Good call,,,all the ones we have at work,,(f250),,the aluminum part across the front where the thermostat located usually cracks where the plastic and aluminum meets

Mustangs generally fail on that end too, however I have seen a half-dozen or so where the heater core nipple has failed. Sometimes mechanically (perhaps damaged) and a couple where the plastic eroded.

The most common failure I have seen on Mustangs is that the inner wall of the formed seal retaining groove under the T-stat housing erodes and the seal pops out into the coolant passage, it then leaks through where the housing and manifold flange join.

Unfortunately the manifold sold by NAPA is a rebranded, universal fit, Dorman unit. One that I would not recommend for use on a Mustang unless it was something one needed NOW.

Belkamp manifold from NAPA:



Dorman manifold from Autozone:



Unless they have changed it recently it is basically a non-PI manifold (smaller lower plenum volume and old-style runners) modified to bolt up to the PI heads...
