Growling is back.....

[jpflip]

Yes it is back. On my last oil change i have switch from Mobil 0W40 to Castrol syntec 5W40. There was no more lack of oil pressure on start until last week....Did around 500 miles with this new oil and the growling is now there at every cold start.. The tsb 1728 was done twice to be sure this valve was not at fault but no success......Really discouraging....

Sorry about this post but I just realized that sounds to be normal for some people..... Feel better but stupid.....

You say 'at every cold start', but how long between starts? If I use mine daily I hardly get anything, but if I leave it a week it makes the same sound as your video, for maybe 3-4 seconds.

Thanks Richard for your input. In fact when I used the car once every day I've never get the noise but after a couple days without using it I'm most certain the noise will be there. It's seems to me so abnormal and when that happen I feel like when you are listening to someone who is running his nails on a chalkboard. May be I'm getting car hypohcondriac.

That TSB is if you have no oil pressure and a warning lamp on due to the no oil pressure which isn't happening in your case.... you have oil pressure within a second after start up. It sounds like a timing chain tensioner has leaked down which is common place when the vehicle has been sitting. Some engines bleed down over a 24 hr period while some engine bleed down over several days. If the problem doesn't worsen and stay consistent I would consider it normal for your engine.
