ticking 4.6 please help!
Hey guys,
I have a 2002 Ford Expedition. It was making the dreaded timing guide noise. Just that, it was not making any other noises. Not a problem. I took the timing cover off. Both tensioners and the guides (all 4) were pretty messed up. Chain had eaten through them. No big deal. I replaced the tensioners and all 4 guides. Though everything was in the clear.
Put it all back together, and right on start up it was ticking. It sounds like it is in the valve train. I was like what the heck? It is considerably loud, actually it sounds like a diesel. The sound increases and decreases with the engine rpm. I am positive the timing chain didnt skip a tooth. It has all new parts, a this is new. Oil was changed, and I am just bummin right now.
Can you guys think of anything?

The oil pressure is fine. It never made this noise ever. I wouldn't think that replacing the tensioners and guides would effect anything else. It was fine before I took it apart, replaced the parts and now it is doing this.

Rod knocking or a broken piston. That is WAY louder than a valve train knock. Listen here for a valve train knock. Around 22 seconds.

Does the sound ever go away??? If it eventually goes away or softens down it could be your catyillac coverter... Mine just went on my denali and it sounded like a real bad rod knock just like that, but then it would get quieter as i drove it more... Just suggestion....

I know for a fact it is in the valvetrain.
I am going to drop some straight 40 weight in her and see what happens.

The sound hasnt gone away. However, it is getting quieter. That is kinda nice. I think when I removed the tensioner the oil pressure dropped in the the lifters. I know they aren't technically lifters, but.......

I would put good money on it being anything other than a valve train knock.

Well guys....................
It wasn't a rod knock, nor the lash adjuster........
I was the timing chains themselves. They were streched and the slapping themselves. Problem fixed, thank God.
