Seafoam for lifter noise?

[kapk22]

Just noticed a little lifter noise today. We use to hear the same type of knocking/pinging in the older crown Victorias due to the crappy gas. 
 

I am wondering if anyone in here has used sea foam to remedy this.

Now the check engine light came on and she says it’s running a little rough and making noise.

Have you checked the oil quantity? 

 

If light is flashing have wrecker load and take to dealer, don't drive. 

 

If older car, possibly water pump failure and coolant leaking into oil sump, watering oil and killing lubrication. Very dangerous to engine. To check, look on dipstick (when you check oil qty and look to see if oil looks ok or whether it looks "milky". If milky, its coolant and don't drive, have towed).

What engine? - please look at putting location and Model & Year in your profile signature - https://www.fordedgeforum.com/settings/signature/

 

What's the mileage?

What's the service history, oil change intervals, and oil used?

 

If you've not kept up with the oil changes then the sludge that forms will cause poor oil circulation and lifter noise and bearing noise will result - you may be lucky that the use of Seafoam cleans the engine up BUT if you use it to clear sludge from a badly maintained engine, make sure you do a few oil changes at very short intervals because the sludge and debris dislodged by the Seafoam will trash the engine in very short notice.

 

I'll also ask the same question as @enigma-2, have you checked the oil level and if there's oil on the dipstick what does it look like.

Cleaning hasn't been the issue, so I don't see Seafoam doing much of anything unless you have bad varnish buildup in the engine.  Cushioning is provided by additives like Molybdenum and full synthetic base components like ester oils.  It will be trial and error as to which oil works in this regard.

 

Some have reported Amsoil is effective.  In my testing thus far, Driven FR20 has been quite effective.

 

As to +ve effects on wear/longevity, IDK.

found the oil was down about 3/4 of a quart and she just had it changed about three weeks ago. 
 

2010 edge sport 3.5 liter 

 

118,000 miles

 

 

 Codes found - P0174 and P0171

 

pulled the mass air flow sensor and cleaned it according to instructions. 
 

reset/cleared the computer with obd reader. 
 

she just filled up with premium and waiting to see if the code (check engine light) comes back on. 
 

I am thinking we may need to replace the mass air flow sensor, air filter, and evap purge valve. I don’t want to just start chasing parts, but I believe the MAF sensor should be first, if the same code comes back up. 
 

I also realized (remembered) dad pulled the air filter out and blew it out with the compressor when we cleaned it last weekend.

P0171 & P0174.

• Problem on the MAF (Mass Air Flow) sensor, dirty or faulty MAF. Over oiled filters will cause the MAF to attract more dirt
• Downstream vacuum leaks of the Mass Air Flow sensor
• Possible cracks or damage on the vacuum connection or PCV line
• Stuck open or faulty PCV line
• Faulty or failed oxygen sensor
• Failure in the fuel injector
• A dirty filter resulting in low fuel pressure
• Exhaust leak of the first oxygen sensor and engine

Look for vacuum hose/connection leak. I had a hose crack and got these codes (Ford fixed under extended warranty. Years ago and warranty paid $160+ (forget exact cost)).

wow!

 

I did not see those other possible issues on the tester we used at the parts store. However, she filled up with premium Friday morning, after having the codes reset (cleared with a tester her son has).  
 

the check engine light is still off and the car has not ran rough or started the way it had been.  I am hopeful the cleaning of the MAF sensor did the trick. It sounds like we will have to wait another couple of days, or until she has driven 100 miles to see if the light comes back on. Crossing our fingers. 
 

as far as the vacuum lines go, I watched a video on YouTube where a mechanic used a smoke machine to find a leak in a Ford Expedition. I don’t have access to one, or that would be a great test. 
 

thanks for the additional info.
