Default Intake Gasket Question

I know if your head gasket leaks, you can mix up oil and coolant and obviously nobody wants that. What about intake gasket? I've been told by my mechanic that the intake gasket is leaking, and I want to know if I have enough time to wait for a little bit (until it's warmer, quits raining, and the effects of this $500 clutch cost to wear off) before I tackle that project. If it's possible to swap oil with coolant from a leaky intake gasket, I'll be tackling that project this weekend. If not, I'm going to sit on it for a little while and just deal with the idle. Ps, this question is geared toward my 02 ranger. Also, the CEL is not on, but I haven't had it ran for codes (unless that's what the mechanic did. I didn't ask. Guess I should have done that )

Thoughts?

Edit to add: I thought it might ought to be a good idea to call the mechanic to see how they figured out what they figured out. He said they did not run it for codes, but they sprayed some kind of carb spray (???) that sealed the leak momentarily until it dried off and that's when it started idling crappy again. I also had the presence of mind to ask him if it's possible to trade oil with coolant with a leaky intake gasket, and he said no. Anyone care to confirm that?

No coolant or oil flows between the intake and cylinder head on the 4 cylinders.

He used carb cleaner to check for a vacuum leak. It'll briefly seal the leak and fix a rough idle. I just pulled my intake and replaced the gaskets. Make sure you've got a 10" extension for your sockets.youll need it to acess the bolts on top of the manifold. The bolt on the bottom in the back is tricky but it's possible. Good luck! Start to finish it should take about an hour or less.

Which year and engine do you have? I was excited when I bought this truck a few weeks ago because I knew it was a 2.3 like my 95 used to have, but was kind of surprised when everything was set up differently. If yours is the same as mine, I might try to prod you for some advice once I take everything apart.

I take it you're referring to the '02 Ranger in your signature, right? If so, then yes, it is a completely different motor. The Duratec engine you have was specifically engineered to have an intake manifold that pisses off literally everyone all of the time. That [redacted]ing hunk of plastic gets in the way of almost every possible engine work you can do.

On the note of coolant and oil though, it is worth keeping in mind that some intakes are set up to flow coolant through them. It seems to be more of a thing on V engines where the intake is in the middle on the top of the engine though. I've never heard of an inline engine that gets coolant like that though. There might be some aftermarket throttle body setups or something that have coolant flowing through them, but they'll usually be through external coolers. The gaskets for this one are incredibly straightforward. Just make sure you clean the surface on the engine and have a really disgusted look on your face when you look inside the runners and see the sludge-like carbon build-up.

My 2000 Ranger
Ruptured intake manifold gasket.
Leaking from coolant port right into top of head and then, of course into the crankcase.
Yes it is possible.
Especially since the rear coolant ports are now blocked off.
Spark plugs looked fine. engine runs great.
Compression test good
I could actually drain the radiator out the oil drain plug.
I worked for Ford Lincoln/Mercury for 11 years.
The only question I have, is this:
Do you still need to put RTV around coolant ports when using
a Victor gasket?
