P0116 code,

bought a used 08 4x4 V6 4.0, with a P0116, and cam and crank code 0335? Changed the Cam sensor, no help, took it a local trusted shop, found the Cam planetary, was missing the device to send the signal to the cam sensor, im including a pic, this and the chain were changed, alittle less than 2100.00 this truck had 76000 miles on it, apparently never properly serviced. Lots of sludge in it. Pic included so others can be better informed, running some Seafoam in the oil to clean it proper, after the shop cleaned it.

 

Yikes

 

Holy crap. I'd remove as much of that as I could with some plastic scrapers first. When you flush it, there's a really good chance your oil pick up on the pump will clog and you'll have problems.
When you do flush it with Seafoam or the 'solvent' of you choice, I wouldn't run it too long without dropping the oil pan to check the pick up.

 

That engine is done brother.

Run what you would like to on it, but there is no way that thing is NOT going to die an early death.

That's what happens when you go over 10,000 miles between oil changes.

 

Fram oil filter explains it all.

That looks like something out of a scary movie... good lord. Find a low mile engine from a wrecked truck and swap.

The "local trusted shop" changed the chain!!!! fuckin a they bent you over with doing any work on that motor.

 

Well, it runs good, sounds good, the shop cleaned all the sludge out, im using the seafoam ask a extra precaution, good compression, and the fuel mileage is not bad, going to cross my fingers and run it until it falls apart.

 

Did the shop also clean up the oil pick-up tube, in the oil pan? If they haven't, please get them to.

 

Yes, and what was amazing to me, the oil pressure has been good every time I have driven it, so it never lost oil pressure.

 

Keep us posted. If it continues to run well, it's a real testament to the durability of these engines.
But damn.....

 

are you going to do a quick drain? seafoam will dislodge the sludge, but you dont want to circulate it much!

 

The shop cleaned and flushed it, going to do a oil change at 1000 miles, added just a little Seafoam to help make sure it gets the small stuff missed.

 

Its from West Virginia, should have known better, I from Martin County across the Tug River, but it does have the new frame from Toyota, ill keep it posted if anything happens.

 

That filter has nothing to do with this. This is simply a lack of oil changes, going too far on probably sub par bulk oil. Even the "darling" Toyota filter would suffer badly under neglect like this. Any good filter would go into bypass at this point from plugging up.

 

I wonder if the oil was ever changed. I've never seen an engine with that much sludge before. Just wow! I too would be looking at replacement engines....

Good luck!

 

Holy shit. Thats nuts

Ok so 250k mi instead of 400k+. Whatever will he do.... These things are tanks

 

The original owner must not have know what an oil change is.

 

Well he was a West Virginian! Lol, day at a time, the truck runs great, no engine noise. Just see how far she goes.

 

Agreed. I wish I could find it, but I took a picture of the inside of my 3.4 liter engine in my old T-100 when I changed the valve cover gaskets at 221,000 miles. That engine was close to spotless. I was blown away when I pulled that first valve cover. I had that truck for 17 years and ran Fram filters and Castrol GTX dino oil.
The filter and oil have little to do with it, in my opinion. Just keep it changed on a reasonable interval for the service use it sees.

 

it was a joke lol... fram has a bad wrap (cus lets face it they dont have the best filter media)... original owner didnt care enough to either get oem toyota filters or get something better like wix... makes sense why they didnt change the oil at all.

 

My much lower mileage 22RE looked spotless as well when I did my last valve adjustment @120K miles. (My truck was killed by a semi not too long after that, so whoever got that engine from the wrecking yard got a gem!)
