2001 Durango 4.7l. No compression on all 4 cylinders on ONE side. Decent compression on all 4 other side. Ideas?


That is an overhead cam engine - a separate cam on each cylinder head. Remove the valve cover on the side with no compression and see if the cam is turning.

Cylinder head tightening


You have a blown head gasket that needs to be replaced. The head may be warped too so it's not an easy job to do without the proper tools and parts.

How to remove cyl heads


Buy a chiltons manual that's specific the the cyl heads your trying to remove. I'm guessing your talking about heads on a car ? By not including a make, model, year , engine size , diesel or gas, overhead cam, naturally aspirated, turbo, fuel injected, carbureted there is no way to answer the question you are asking. Your biggest concern should be on how to reinstall them. Reinstalling heads are far more complex than removing them. All heads are different in the pattern in which they are tightened down ( to prevent warping ) . A specific amount of torque must be applied to each bolt. Some bolts require thread sealant because they pass through the water/coolant passages in the engine. Failure to do that will result in water leaking into you combustion chamber thus ruining your engine as well as your new head. Also the thickness of the head gasket must be correct because to thin or to thick of a gasket will change your engines compression ratio . The gasket thickness can also change your cc's in the combustion chamber. A gasket that's to thin can also allow the exhaust or intake valve to hit the top of the piston on the compression stroke. If your dealing with an overhead cam or dual overhead cam engine then the proper setting of the camshafts when reinstalling the head or heads is crucial . The above only pertained to gas engines. If you have a Diesel engine then things change dramatically . The pressures in the cylinder head combustion chamber area on a Diesel engine is unbelievable . One small mistake or oversight on reinstalling a head on a Diesel engine can be catastrophic .

Trying to locate engine number to determine 16 0r 32 cam


Unfortunately, your question is very vague and hard to understand.

16 or 32 cam?
Usually your engine will have twin cams, or single cam.
Overhead cam(s) or not. You could determine if your engine
is a 4 or a 6 cylinder, and then you will generally find out how
many valves the engine has.

If you are in a 4 cylinder car, you probably have 16 valves if you have a twin cam engine.
If you have a single cam, 4 cylinder engine, then you will usually have only 8 valves.

The only way that you could end up with 32 valves, is if you have a dual overhead cam, v-6 engine.
Each head will have two cams, and each cylinder will have 4 valves then.

I hope that this is what you were trying to ask. :)

I need to find out where the push rods are at in


If it has push rods, you will find them under the rocker cover on the top of the engine, they are hiding under the rockers. The rods ride on a lifter that rides on the cam and then they push the valves down, and squirt oil all over everything, a spring brings them back up. The overhead cam eliminated all these extra parts. Lifters, rods, rockers. Hope this helps.

Knockin noise at the top of valve cover, no motor power ,cyl 5 6 misfiring 92 maxima


Sounds like you have a couple of failed valves. Do a compression test on cylinders 5 and 6. You will have very little compression in either cylinder if valves are broken. You will have to have your head rebuilt at least on those two cylinders and possibly piston work depending on how the valves failed.
