Here is my latest UOA on my 2004 Nissan Sentra 1.8L with ~48,000 miles.
Oil was Royal Purple 5w30 with about 5,200 miles on it.
Car is mostly used for a 2 mile commute to work and back in stop and go traffic.
I have had a gurgling sound from the heater core for almost 1.5 yrs. I thought it was just air in the system from my poor coolant change job until it was suggested to me that the headgasket might be leaking combustion gases into the cooling system which is why all efforts to bleed the system fail.
The UOA seems to support this but it would be nice to here other opinions on this from the forum members!
