Just within the last couple days I noticed my 274 800km V6 making some intermittent griding/chattering noises from the valvetrain on the front bank.
Upon start up,it's quiet,but shortly after it starts idling,you'll hear a "grind grind grind" for about 5 seconds and then it stops and idles quietly again for about 15 seconds or so and does it again. I also noticed this condition after pulling out of the parking lot at work this morning,while driving slowly,you could hear it chattering away,even under light acceleration.
I use regular 10W30 oil and added some Slick 50 that my dad had sitting around on Saturday. Adding the Slick 50 made the car feel smoother and run smoother,but didn't eliminate the grinding/chattering. When I am due for my next oil change in 2000km,perhaps I should try that high milage stuff? A friend of mine had knocking valves in his 240SX and used that stuff and said it took the knocking away.
Maybe it's something else? The car runs fine,it's just noisy. I don't know what my oil pressure is like since we don't have oil pressure gauges (how stupid),and it's only coming from the front bank.
Any suggestions...apart from a 3.0L swap?
