Core Plug replaced - why?

[SteveMelchiorre]

Quick question for you guys.

The Previous owner of my '69 Mustang replaced the first core plug and its now begun weeping a bit around the edges.
I do plan on replacing it with a proper brass one but my question is - Why would the previous owner pull and replace this one core plug? The others all look to be much older. Any ideas?

My have rusted through. I would replace them all with brass plugs

If it's the one in front it would maybe have had a block heater.
And since you live in BC and never have to plug in your car you probably don't need one, but if you lived anywhere else in Canada I'd suggest you replace it with a block heater. :santa;

Fair enough. I never knew the block heater went in the 1st Core plug.

I'll be putting in a set of CI Headers later this summer.
Can I also assume that with the exhaust manifold off the car, replacing the core plugs is a pretty straightforward operation?

Any hints or tricks?

If you can get access to the plug with a body repair slide hammer with a self tapping screw end (even a cheapo light duty one is fine), it will pop out easy. I used a socket that fit snuggly into the inside of the new plug and lightly tapped the new one home. NAPA recommended a product called gasket cinch for sealing and that's what I used.

Although Brass will last longer , its more prone to leaking a Steel is , The steel ones last 100,000 miles with proper cleaning and flushing ,how long are you going to keep it ? just a heads up

My last Mustang ('71 Mach 1) was with me for 12 years.

This one is my Daily Driver and I intend on keeping it and driving it for as long as I can.

8) the block heater doesnt have to go in the first opening, but it usually does as it is the easiest one to use with the engine in the car. as for your other question, yes, once the exhaust manifold is removed, it does make it easier to get to the other core plugs.

On the off chance that it was the first to rust out and leak and you'll be able to change easily, change they all. 3-M upholster cement works great. The shop never had any come backs.

Thanks for the advice Thad.
Is this the cement you mentioned?
