I've got an '04 Tacoma with V6, that has a slow coolant leak.

It's got 177,000. miles on it.

The local shop did a pressure test to see where it was leaking, and they say its either in intake manifold gasket, or a head gasket, and they think it's the head gasket.

They said it would be $900. to $3,400. to fix it, depending on what they find when they tear into it.

They said it would be best to do a valve job on it, while they are in that far.

I haven't had to add any coolant in the last 200-300 miles, so it's not leaking bad.

I can get a complete NEW long block put in for $7,000.

Am wondering if maybe I should just run it 'till it "pukes" then put $7,000. in it, rather that spend $3,400. now, and end up having the bottom end go in a few years?

Thanks for your thoughts! Virgil B.
