Zero compression, engine is shot. Blown Intake and head gaskets can let water in the pistons, But usually not all would have water. Intakes can dump water in the oil also.
usually no unless there is so much build up on all the valves or are bent, they won`t close. you don`t say what year make engine of the van or why you suspect intake valves.
Have the engine computer scanned for trouble codes. Misfires are from loss of fuel, spark, or compression. Check the fuel pressure, check that all spark plugs are getting spark, and if all good so far, test engine compression. Low compression in a cylinder will cause misfires and loss of power.
It could also be a vacuum leak- a loose or cracked vacuum hose or an intake gasket leak.
Boy, it sure seems a lot of work to capitalize every word...
It is an odd answer, but I think one or more of your intake valve are not sealing. Engines make a horrific amount of noise if you pull one spark plug, then start it with the other plugs still in.
There just is nothing in the intake system that can make noise, except what is on the other side of the intake valves.
Do a compression check. If the intake valves are having a sealing problem, the compression will be low.
If the cam that opens the intake valves is late, you could get a short backward flow just before the valve shuts, which could make some noise.
This is a truly odd complaint you have. But that;s all I can think of that could do this.
In order to run a turbo you have to have low compression in your cylinders. when you drive to aggressively you can blow you turbo out and you car will have no power at all. A turbo pushes air into you intake in order to get that power. if it goes out your engine will run like its 30 years old and blown. get a new turbo. take care and good luck.
How about some history.. like was it running OK and then was parked, and later would not start? or has it been sitting? or quit while driving down the road?? Mileage? Does it run good now? If so I would recommend using Chevron Techron Fuel additive to clean up the injectors and back of the intake valves. That could help if indeed the valves are a problem. Some repair shops have a Motorvac or BG Injector cleaning/ intake manifold cleaning that would possibly help that.
You said you did to specs but if that was the case the valves would not be open at tdc.
triple check your timing(get a light if nessisary)
check that you dont have the plug wires mixed up
Note:
Izuzu engines are very picky and if the marks are not correct after turning over two rotations as stated in the book it will not run.
(im also taking that this is the v6SOHC engine)
