help...coolant leak

[black35th99gt]

has anybody else had trouble with a coolant leak where the thermostat housing comes together with the intake, mine is leaking and i tried to silicone it, but it keeps leaking into the spark plug hole and causing a cyl. 5 misfire, i was wondering if there is a fix or buy a new intake, i am trying to sell the car, but i cant like this

It time for PI intake swap, My PI intake is in machine shop , drill and tap and clean up, before I put it on my 98gt tomorrow. Search is your friend. Wait you have 99 gt ? well I guest just swap the cross over with aluminum cross over.

replace the intake. Dorman has one with the aluminum crossover, both holes tapped (if you need them), a plug for one (if you only need one). No gasket required, the gasket is built in to the intake. It is a perfect swap, PI configuration, easy to install. I bought one thru a local Advanced auto parts for $200 bucks (their normal price was $280, but Westwood had a 200 buck price and advanced matched it...)

Works great, t-stat housing is aluminum along with the head-to-head crossover for coolant. The only good thing is that at least these don't split and let water into the intake like the GM plastic intakes did. This is just irritating. The GM EGR meltdown problem smoked a lot of engines completely when it hydraulically locked 'em up.
