Extension of oil change interval. No mineral oil has entered this engine. The polytron addictive prevented further damage. If engine has been running on a 20w50 engine would be knocked

Is the right side of the engine missing chain guides?


I think they never changed the oil just topping it off.

If it was changed the gunk won't build up like that. The owner might be saying one thing but since none can actually say they saw the oil changed work with the worst case scenario.

We have a Toyota 4runner 2007(V6). 1GRFE with the following fault errors pulled out from the pcm

1) P0016- crankshaft position-camshaft position correlation (bank1 sensor a)

2) P0022- camshaft position 'a'- timing over ratarded(bank2)

3) p0012- camshaft position 'a'- timing over-slow (bank1)

4)P0456- evaporative emission control system leak detected (very small leak)

Symptoms exhibited by vehicle:

1) oil light flickers
2) so much internal engine noise
3) sluggish movement

Diagnosis:

** Since oil light flickers, an oil pressure tester would be used to determine oil pressure from the oil pump using an OTC oil pressure tester. After this is done a comparison would be drawn based on what the manufacturer recommends

N.b oil pump is an internal part within the engine


a lot of sludge and worn our bearings

Engine comes down. grin

Following to see what happens next.

Troubling pictures.

Not sure how a vehicle allegedly serviced on synthetic oil ended up like this
Re: Toyota 4runner 2007(1GR-FE) Fix by 9icetoo(m): 11:39pm On Sep 03, 2018
Owner is either not aware of the vehicle oci or is being economical with the truth. There is no way a vehicle serviced with synthetic oil will end up like this. Except maybe the synthetic oil he has been using is adulterated.

I maintain that oil has not been changed in over a year.

Best case scenario here is to try and clean both upper and lower part of engine with brake part cleaner, put engine back together with new timing chain kit, run the engine for about 5-10 min with engine flush+oil then change to oil only(information for those dealing with sludge not necessarily this case)

Can't post pictures but when I opened my Octavia valve cover, even the mechanic that came to inspect the injectors was astonished at how clean the internal of my engine was. My Camry was same when I changed timing chain. Never opened the Honda city but looking through the oil fill hole, it looks spotless. I've also seen some friends engine internals especially when changing valve cover oil seal and even the ones running mineral oil don't have it this bad. This person has been skipping oil changes.

what kind of gasket did you use? Graphite or steel multilayer? if the latterhow did you handle the cleaning of the mating surfaces to assure no leaks whatsoever?

Secondly did this engine suffer oil shortage due to its poor state?

Excellent job btw... You truly deserve some accolades #teamsreplacerebuild
