Vehicle is a '02. I'll take a look at the Liqui Moly additive. Should it be used in place of MMO/Seafoam additive? I've recently used Seafoam through the TB, and I USED to put MMO in my fuel. It would quiet the injectors quite well. Although, I haven't used it in a while.
I'm with you. It's a quick sound. I haven't heard any clacking/ticking sounds after sound I'm concerned about. I'll experiment with different weights in my future oil changes, starting with 10/30. Then I'll find the sweet spot.
Ironically, that's what's in there at the moment. I forgot the cap orders 5w20, and I bought a 5w30 version of the Castrol Ultra-Clean. I'll do a good 10w in Motorcraft oil my next oil change. I'll have to find the proper time to complete the service.
I may switch to 10w30 on my next change, and then if the rattle still progresses, I will switch to 5w40. It may be a temporary band aid, but I dread doing the timing. The passenger valve cover was absolute hell, so I would probably aim towards an engine pull route.
Thanks! I actually tried that last night, and that helped the issue. It has been happening for quite some time now. It's only at startup. Purrs like a kitten, and the only audible click is the noisy injectors. I'll try the flood mode again tonight.
Hello all. As of today, I am a new member here at B.I.T.O.G.com. My question in concern is a very quick, quiet rattle noise at a "Cold-Start" (or when the car has been sitting for over 4 hours). My vehicle has 120,000 and I have been the owner since 109K. I have done 3 oil changes so far, 2...
