Have someone get their ear down near the head mating surface while the engine is being turned over, and see if they can hear air whooshing through a gap or something.

Verify that the cam is turning.

Remove all the spark plugs, seal off one of the holes with a thumb, and see if there is any compression at all while cranking. If there is sucking and pressure on every stroke, the valves are not operating at all.

Turn the engint to top dead center on the No. 1 cylinder. Remove the valve cover(s).

Using the firing order, find the cylinder that is exactly opposite the No 1 in the sequence. As you move the engine back and forth past TDC and back, either the No 1 or its counterpart is transitioning between the exhaust stroke and the intake stroke. On one or the other you will see the ehaust valve just finish closing and the intake just starting to open as you cross TDC. If that is not the case, the cam is not timed properly, and compression can be realy affected by that.

With no compression at all it really seems that the problem is something common to all of the cylinders...

If the cam is operating properly, and at the right time, then perhaps something is holding the valves from closing all the way.

If the engine was moved through TDC or BDC or both without the cam turning, or with it mistimed; or if the engine was at TDC or BDC and the cam was turned, it is possible that the valve heads were bent from contact with the piston(s).

I have a 2000 chevy astro van with misfire code in cylinder 6. I was told that i have to replace the spider, fuel injectors. Could it be something else?

If, in fact, #6 fuel injector is faulty, you need only replace THAT one injector. If once you've replaced said injector and another check still shows #6 is misfiring, same code, then you have a faulty exhaust valve and are losing compression. Best to do a compression test on all cylinders with all spark plugs out before changing that injector. It could be good yet and you'd have changed it for naught. Compression test first, it's simple. I'f test shows low compression on #6 then the valve is bad and you'll have to pull the head off and d a valve job to re-seat the valve. Once re-seated, turn the face of the head gasket surface up flat and pour some alcohol into the head combustion chamber. If it doesn't leak out, your done. Put it back together.

First of all my mate bought a vauxhall corsa duel fuel he drove it from heathrow to where i live about 150 miles he said that it wasnt pulling good did compression test and number 2 and 3 had no...

It might be a silly question on my part but here goes.

Did you put a new gasket between the head and block. Only reason you would have water in the block is if the block was cracked or the head gasket was defective.

Do i need to have my 2004 dodge intrepid anti theft code reset through a dealership if the heads and head gaskets were replaced? the entire top of the engine ws taken apart adn put abcl together.

i would disconnect the battery. removing both the positive and negative battery terminals. with both ends disconnected, hold the two terminals together for about 10 seconds. this will proform a hard reset on most chrysler vehicles. also, if this doesnt work, try turning the key to the on position, and then proforming the hard reset procedure.

Put rebuilt head on now engine smokes and has aqlot of blow by

any time you put a new or rebuilt head on top of a used motor you are going to get some sort of blow by. the more miles one the Rings the more blow by you will have. when you put on the rebuilt head south the new valves. you increased the compression ratio. thus making the worn rings from being able to hold back all the compression. next time at least drop the pan and put new rings in. better new pistions and hone the cylinders. best pull the block have it bored .20 over (which gives you a 2.0L ) have the crank turned. have the cams inspected for ware. and just replace old with new. yes.its more expenses in the beginning but well worth it. because look were you are now. to fix it you now have to start over with a lighter wallet

Malibu was leaking water - changed intake & head gaskets - put all back together but now sounds like it is out of time and won't start - do you have an answer

One common issue when a shadetree mechanic changes the head gasket is that during the removal of the timing chain/belt and it's corresponding sprockets that the camshaft and crankshaft timing chain/belt sprockets are allowed to turn relative to one another if not properly indexed before reassembly. This causes the valve timing to be quite off once everything is put back together.
Checking to make sure that compression is proper in the engine should resolve whether or not this is your issue.

There is a way to check the timing ...a timing light but if the cars not running this will not help i would call that shop and tell them they messed your car up and have them fix it ...could be a lot more wrong with it other then just the timing if they pulled the heads
