Ok my moms car is an 02 GP gt 3.8l non supercharged, it recently started a nasty valve train noise, seems like it isn't getting oil up in the heads. The car only has 77k (i know that don't mean anything) and started doing the noise intermittently. First time she told me it was making a noise now I started the car and it was quiet as can be. She told me it came back a day or 2 later and it sounds like from both heads, the rear sounds slightly louder. Also now it does it every time it sits. I even had it sitting inside the heated shop last night and still did it
What i've done so far: Oil change with 10w30 w/ 75% of a bottle of Lucas oil stabilizer, while i had the filter off i blew compressed air through the filter housing out the pickup to make sure nothing was blocking it.
I started the car and after about 2 minutes the noise went away and i could see a little oil flowing in the head through the oil fill, not as much as i thought it would be but i havn't played with these motors too much yet so i'm not sure. Almost sound like a lifter losing its prime? Once it gets passed the 2 minutes or more it runs beautiful.
Thank you for your time for reading and please any ideas post them!! Or even similar problems.
