1. Complaint: Poor Run Condition Stumble on Acceleration
Road test w/ shop Inspection. Test & Diag. Isolate EGR system for on-off evaluation. Is working properly. Significant vacuum leaks detected at intake/exhaust manifold assembly and air injection rail. Carburetor idle adjustment not correct. Compression check: cylinders #1-3 @ 150psi, cylinder #4 @ 135psi, cylinders #5-6 @ 155 psi.
Recommend intake/exhaust manifold and air injection rail replacement. Recommend valve clearance check and adjustment as necessary. Recommend Carburetor adjustment.

2. Complaint: Overheat after 1 hr highway driving. Occasionally spits coolant out relief hose.
1 gal. low on coolant upon inspection. Top-off coolant. no external leaks detected. Radiator & hoses in poor condition. Could not determine head gasket/cylinder head condition at this time.

3. Complaint: Exhaust fume smell in cab.
Poor run condition causing fume build-up.

4. Complaint: Check various leaks
Power steering pump leaking badly.
Recommend replace.Front Axle knuckle seals leaking. Oil gauge sending unit leaking. Transfer case rear output shaft seal leaking. Transfer case idle shaft seal leaking.


So i decided to tackle the p/s pump, intake/exhaust manifold and injection rail. After reading the response of my first post http://forum.ih8mud.com/60-series-wagons/290518-how-love-you-truck.html I decided to check the manifold gaskets first rather than replace the whole manifold. Gasket crumbled upon removal. I've pulled out the p/s pump and injection manifold which was rusted and crumbling as well. I'm not sure what the valve clearance check is and starting to feel a little in over my head. Now that I have the engine block exposed wondering if there are some basic things I should do before I start to put things back together. Comments/Advice?

Here are some pics of my progress.
Draining p/s, removing carb, removing manifold, engine block exposed, manifold out front & back, engine block.

You might want to do a compression test to see if you have a leak if you are burning up a lot of coolant and don't know where it's going.
