Valve Problem Possible on Windstar 2000

[Searles Lewis]

Here is a video with the engine and noise. I spoke to my neighbor, he stated the noise and vibration can be from anywhere, so next I'm doing a valve compression check, will post results here.

If nothing happens, I'll take the front valve cover off after that!

What do you think?

I'm not any expert, but it is sounding more like something other than a loose part in the upper intake manifold.
A broken valve spring or rocker arm is a much easier repair than many other things....and are things that folks have reported having had happen on their Windstar.
If it is in the front bank, that would also make it much easier......that is a long lean over to reach the back bank.

I do not think that it is anything driven by the serpentine belt....but to verify, you could take the belt off.....and start the vehicle....running it only a few seconds won't hurt.
If the sound is still there, then it is not something driven by the belt......if the sound goes away, then it is something driven by the belt.

I have always had a really hard time locating the source of sounds in the engine compartment.....even using the screwdriver to the ear method.....the sounds have always saturated my hearing to the point that I'm only guessing, usually wrong.

Please do not start any more threads on this probblem as it is to hard to follow with multiple threads.

Olopezm and Wiswind have a very good suggestion to remove serpentine belt to help eliminate possiblities. Very possible that the harmonic balancer is bad like Olopezm suggests, you mayy have to remove right wheel and splash guard to inspect and or remove.

To me it sounds like something hitting against plastic but hard to say with a video. Another possibility is that you have a a bad connecting rod bearing causing the knock. Report results of compression test.


WE NEED A ANSWER TO THIS QUESTION:

WHERE WAS THE ANTIFREEZE PUT INTO THE VEHICLE???? WAS ANTIFREEZE PUT INTO GAS TANK OR WAS IT PUT INTO THE ENGINE CRANKCASE THRU OIL FILLER CAP????? ANTIFREEZE IN OIL WILL DAMAGE BEARINGS.

It was put into the gas tank on Dec. 20th, by my landlord. I confirmd this by removing the fuel filter, which had green stuff oozing out of the intake side. It was anti-freeze. He was trying to retaliate for my attempting a wage garnishment against him.

I checked the valve compression-120-130-13-120-130-120, all fine.

My friend stated it might be a problem with the timing. I know he has broken, my landlord, into people's cars and apartments in the complex, and to tick other people off with kids, hired a convicted child molestor to do apt. maintenance, so I remembered back, and this happened about a week ago, maybe less, and I think it looked like when I popped the hood, two of the rear spark plug wires had been switched. That might account for everything.

The problem is, the haynes manual I have does not have a numbered pic showing the coil pack, and the spark plugs they attach to from it.

Does anyone know where to obtain that? My friend stated it also could the crank sensor affecting the timing.

What I figured I'd do is:
1. Re-attach the spark plugs and wires to the coil pack in correct order; and
2. Pour the remaining B-12 Chemtool into the engine compartment, run for a little bit, and then change the oil to make sure a lifter or rod arm is not sticking.

What does everyone think of that?

Was the anti-freeze put in the engine oil or in the gas tank??? If in the gas tank, the problems would be in the fuel supply system not internally in the engine as it would need to pass thru the injectors to get inside the engine. On the other side if in the oil the anit-freeze will cause damage to internal bearings and cause them to fail in time.

You say that it will not turn over. Did your friend try turning the engine with a socket and breaker bar on the crankshaft bolt that holds the harmonic balancer in place? Were the spark plugs removed to see if engine would turn over then?? Starter could be lockeed up also. More diagnoses need to be done to determine problem.

You were right about the whole thing. Not a valve job, but probably timing-think the landlord jimmied the van's door, then popped the hood and switched the spark plug wires.

He mostly hires convicts, so I'm sure if he did not already know how, one of them could show him how to do it.

So, to continue...

I checked the valve compression-120-130-13-120-130-120, all fine.

I'm glad you said that about locating and hearing. My hearing is really, really very good, and I am overly sensitive to a lot of things. However, I lack the ability to locate things like this. When my friend stated it could come from anywhere, he has problems too, it gave me relief as your statement has.

I think it was intentional sabotage. It sounded perfect with the plugs out, no problems, and now I just need the order for the coil pack and the places the plugs go into the engine.

Thanks everyone for the help!

Here's the numbering

Windshield side
1--2--3
4--5--6
Front of vehicle

Coil (it should have a diagram on it if it's original):

4 PIN CONNECTOR
-1--2--3-
-5--6--4-

Okay, I obviously now understand what the ordering thing inthe Haynes book means. Thank you!

I checked, #2 spark plug was cracked all the way around, looked like when he jammed the wire down from above, prolly doing it fast and nervous ,he cracked the plug, it has brown burnt marks al laround it.

I will hook this up tomorrow with new, Autolite spark plugs, plats, all 6, after I gap them tonight.

I will also check the coil pack, too.

Thanks for the visual, I understand he directions now! Wow, all this because he started harassing us, lost his eviction case, and now does not want us to collect the 9k$ in fees he owes for the lawyer.
