Leaking Heater Core
#1
The water level keeps dropping and I noticed the passenger side
carpet was damp Huh
Long story short I have a hole in my heater. Very small hole though.
Bought a new core but what a pain to install. Can anyone recommend
some type of "stop-leak"? At least to get us through the winter
months. I have this philosophy about "additives", don't use them.
I don't like adding any fluids to my car it did not come with.
Can you recommend a temporary additive that won't harm the engine?

No easy fix since you have a barely broken in motor,
I wouldn't add anything.
You could loop the hoses to by pass the core, save the carpet, floor pan and get a jacket Tongue

No easy fix and No additives.
Bypass the heater core and get a jacket.
It is 0700 and the temp is 57 so I will need
a goose down jacket.
Speaking of jackets, did that Ford jacket fit?

I did this job last, I was very happy when it was done, my body as well.
There are threads you probably found talking about this.
And no additive of course, even for a while.

I have used Bar's liquid aluminum stop leak with success and without any negative side effects, on small leaks. Just follow the directions exactly.

Chuck I have used that on older engines
Mike's engine is very new
Since he has to do the core anyways I would use an additive in it this soon.

Don, I agree with you but, Mike asked, so I told him what I'd experienced.
Don, Did you ever get those muffler bearings in stock? Chuck

Wish I knew more about this engine, it is a beast.
Can easily start off in third gear and will go up an
incline in first at 400 rpm. What kind of cam??

Yes but they already sold out again
See Mikes post - it's not the cam it's in the muffler bearings - frees up that rotational torque
