villager missing on cylinder 5
 
95 villager. It is missing on cylinder 5. I isolated the problem by pulling plug wires off the distributor until tbere was no difference off or on. I put an inline spark checker on the distributor and spark is leaving the distributor. Either the wire or plug are bad. Or the fuel injector is bad. Anything I'm missing?

Distributor cap has crack.
Distributor point is bad on 5.
Rotor needs to be cleaned.
Wait till real dark, pop hood open, start engine, and spray saopy water onto wires and dizzy. See what happens.

I checked those first. Cap and rotor are like new. Replaced less than 10k miles ago.

I should have mentioned that.

Plus there is spark at terminal 5. Inline tester blinked normally.

Plug, injector, vacuum leak, mechanical defect on that cylinder. Swap / replace plugs first. Measure the resistance of the injectors (they should be 10%). Spray carb cleaner to the intake to check for vacuum leak.

Plug was oil soaked. I cleaned it, regapped it and put it back in for now. I will replace it this weekend. Now to determine source of oil fouling.

One way
Or another
It is a spark plug
It is a spark plug, spark plug...

If plug is in plug tube, it's bad tube seal. If it's direct into engine head, it's bad head gasket. Have fun replacing that.

Since the oil isn't contaminated with coolant i am guessing bad valve seals. Do spark plug foulers work?

ukrkoz 07-24-2013 09:42 PM

Does it smoke blue when stepped on gas? Who says bad head gasket will nerecessily leak oil into coolant? It all depends where the burn through or rupture is.
I had several engines with notoriously bad valve stem seals, none of them fouled plugs at threads.

Big, bad valve stem seals or bad head gasket - you still have to pull that side head off. It's no smaller labor, unless you one of those magicians that knows how to replace valve stem seals without head removal. IF it is the right guess, which I doubt it is.

"Ain't no magic spell gonna fix this one, main!"

Overheard 20 years ago when 2 guys were trying to get an old le mans running. :)

I'm replacing the plug this morning and testing the injector.

Yeah, tricksters run compressed air inside combustion chamber to keep valve up and then manage to replace stem seals. Brrrrr....
Keep us posted.

I have a snapon tool just for this purpose. Hose with adapter threads into spark plug hole. Cylinder needs to be at TDC on compression stroke so both valves are closed. Plug in airline to hose and it pressurizes the cylinder. Tool looks like a hand held impact driver. Sit it squarely on the top of the valve spring and hit it with a hammer. It compresses the spring and is magnetized inside to grab the collet and keepers. Remove spring(s) and replace valve seal. Special insert goes into tool. Reassemble valves spring, collet and set keepers into collet. Tool goes on top of this and insert goes in between keepers. Give it another smack with a hammer and it puts everything back together. Very easy to use, no magic involved. I bought this tool almost 40 years ago when I worked in a motorcycle shop. Some of the chrome finish had peeled off. My son is a auto tech, so he took it to work and gave it to the snapon guy. He gave me a complete new tool, updated and improved. Was surprised to see the old one. Probably put it in their museum.

Oil seepage is not my main concern. The cylinder is dead and van is dying in traffic. I dropped it off yesterday at the shop; i don't have the time or ability to fix this one.

Bigplanz 07-26-2013 04:16 PM

Injector 3 and 5 are bad.

Bigplanz 07-26-2013 06:05 PM

Anybody replaced injectors under the intake plenum on a villager/quest? $700 repair estimate has me looking at diy options.
