Great day in the darn morning…
Hell my Nissan Altima VQ had the looking litttle bit of varnish on the valve cover like this vehicle has. Slightly golden brown… Now the rest of what I could see inside that VQ motor was totally clean of any varnish. None there… And that was true at 360,000 miles plus by the way.
Now I had cut the interval over time from 5k miles or 5,500 miles down to 3k miles in that Nissan Altima VQ.
The varnish in this motor of it only had say 75,000 miles or 120,000 miles… Then I would agree with some of you guys on the varnish color being on there…
Sweet baby Jesus… That vehicle has darn near 300,000 miles on it… This is not a big frieking deal here.
Good news…. I’d bet good money HPL EC in there would clean that light varnish fairly well in that motor. Use that for 2 times back to back and that would clean that motor right up I would think.
And those cam lobes do look really, really quite good. In terms of that… those are in great shape.
And 3/4 in 5,000 miles is not unusual in those motors. These motors are known for oil return holes filling up with carbon and plugging them up. Therefore leading to those motors burning oil.
