i need help

[frankied570]

Hi i have a 97 ford explorer sport sohc that started once then stalled i replaced iac fuel dilter feul pump and battery and it started up today i drove round the block and parked no problem until i went to go to work tonight and after 2 tries started truck and drove down the street and it stalled it stalled three more times while trieing to drive back to my house it also makes clicking noise now from engine im stumped and realy need help i swapped around relays with same part numbers to check that when it stalled battery light was displayed n no check engine light comes on any ideas??

Can you identify where the clicking's coming from?
When you put the key in and turn it(Not all the way to engage the starter), do you hear the fuel pump cycle?
Have you checked fuel pressure?
When the motor stalls, is it running fine, and then just drops off?
Once the motor stalls, will it start right back up?

Kinda sounds inside engine not all the time and it starts back up but idles rough before stalling and i do hear pump working i just looked at my oil level and looks real high and brown milky sludge under cap thinking head gasket now

 

[frankied570]

Constant sound of hissing now to cant locate

Ok, now I get it.
Lower intake gaskets are cooked. 90% sure.
You failed to mention you were going thru coolant.

The coolant portion of the gasket blows out, and coolant drains in to the motor. Mine did exactly what you are describing. Mine wouldn't always stall, but would stumble.

Better make it a priority to take care of this before you destroy your bottom end.

Heads could be cracked also. But what your describing is lower intake gaskets.
I had multiple issues with mine, including cracked heads.

If I were you Id buy the lower intake gaskets and tear in to the top of the motor. My best guess.

SOHC not OHV

Your first post stated that the engine is the SOHC V6 which has no coolant in either the upper or lower intake manifold. Sludge in the bottom of the oil fill cap is not unusual and not necessarily indicative of coolant in the oil. Check for foam on the engine oil dipstick. If there's foam on the end of the dipstick then that indicates coolant in the oil. You can drain the oil from the pan to confirm. The water will collect on the bottom of the pan and come out first.

What he said!!
I'm jumping way to far ahead in my assumptions.

I ASS-umed it was an OHV by the year.

 

[frankied570]

I checked oil and its overfilled but not foamy from dipstick just under cap but ticks inside oil cap n ive been loosing fluid but not excessively havent drained oil yet tho

 

[frankied570]

And any idea on the hissing from rear of engine (i think the rear)

 

[frankied570]

And if not gaskets what else could this b cam sensor crankshaft sensor???

 

[Dono]

Humour me. Hows your coolant level?
Im pretty sure if it was cam sensor, you would be getting a code.

Crank sensor is on the front of the motor. No bearing to worry about there.

 

[frankied570]

Coolant fine no code but i do loose little coolant i have to add some every few months and i read hissing could be coming from fuel rail

 

[Dono]

That's all good news.
Loosing a bit of coolant every few months wouldn't cause a huge issue in the oil.
Back to.....I don't know what could be causing the stumbling, and stalling then.

There are enough differences from the OHV (What I have) to SOHC that I cant really even guess.

I have ticking too dk what it is as i accelerate it gets louder i changed intake manifold gaskets and changed oil and coolant thier was oil in my intake manifold too any ideas?
