In my Chevy 1500 with the 305 Vortec, the problem was the lower intake manifold gasket, which is the one that seals it to the engine block. On your 3800 V6 (in a Silverado? I didn't know that; I thought it was the 4.3, maybe it's an older or newer year than my body style), it could very well be the same. There is also a coolant line coming out of the manifold, if I'm not mistaken. Could be to the thermostat, but I don't have the truck anymore. To the best of my knowledge, that would be the easiest and cheapest thing to check.

How do you replace an intake manifold gasket on a 99 Bonneville 3800?
To replace the intake manifold gasket on a 1999 Pontiac Bonneville with a 3800 engine, first disconnect the battery and remove any components obstructing access to the intake manifold, such as the air intake and throttle body. Drain the coolant and detach the intake manifold by loosening the bolts in a specific sequence to avoid warping. Clean the mating surfaces thoroughly, then install the new gasket and reassemble the manifold, ensuring all bolts are torqued to the manufacturer's specifications. Finally, refill the coolant, reconnect the battery, and start the engine to check for leaks.
How long does it take to replace a lower intake manifold gasket a 3800 v6 engine?

Will a 3800 supercharger fit on a 3400?
A 3800 supercharger can fit on a 3400 engine with some modifications, but it's not a direct bolt-on. The 3400 and 3800 engines have different mounting points and intake designs, so you'll need to adapt the supercharger and possibly the intake manifold. Additionally, ensure that the supporting components, such as fuel delivery and tuning, are also upgraded to handle the increased power.
