Under the intake manifold, its very difficult!
On a 2002 Isuzu Rodeo, the thermostat is located at the end of the top radiator hose on engine. It is situated under the intake manifold.
on the themostat housing where the upper rad hose meets the intake manifold
Remove the intake and exhaust manifold, then remove the head.
It is located under intake manifold towards the back. It is above the starter.
The PCV is screwed into the front of the intake manifold, top right and has a hose coming out of it.
On the drivers side head..rear of the head directly behind the intake manifold
If air is leaking past the intake manifold gasket it will make the engine run rough. Check the intake manifold vacuum. You should be running a steady 18-24 inches of mercury without touching the throttle. Run a small hose with one end in your ear and the other running around the edge of the intake manifold to find the exact location of the leak. If the manifold vacuum is normal, check your spark plugs and wires. One other way to test is to run a propane torch with no flame around the gasket. The engine will speed up when you run by a leak.
Yow have to remove the entire intake manifold to access it. I highly recommend taking it in and having it done by a pro.
On exhaust manifold.
