2003 Ford Focus DOHC Zetec 2.0 *Cam Gear Bolts Wobbly*

The cam gear bolts seem wobbly, the intake side started first and progressed and now the exhaust gear seems to be starting to do the same
The car is warmed up so its somewhat quiet, but when it first starts there is a repetitive grinding noise, more like a rotating part rubbing everytime it rotates and at about 1200 rpms there is a vibration from the engine.

Ill make another video, but after the car is warmed up it doesnt really make them noises.

The car is running a turbo at 6psi, no engine work though. My valve seals or piston rings may be bad becuase I am running about 100 compression through all 4 cylinders.

Leave comments on what it could be?

Thanks for all the help

Did you find out what it was??? I have the same engine (Although without the extra 6PSI turbo) and I'm always paranoid I wont know what the problem is if I run into one. Especially a potentially engin killing timeing belt problem.

@watcbd i never found out, didnt seam like it was anything

i talked to a couple of my buddies and a shop i go to, they said that it was mostlikely the alignment of the bolt, because the cam didnt wobble and the timing was good

the noise you mainly here, like the click clacking is actually the 42lb injectors that i installed to compensate for the 6psi boost

@PattyWaggon93 i have the same on mine just more :P and i did ask a ford engine builder and he said they do so because of high rpm use:P

[PattyWaggon93]

@solveg18 im not suprised then

well after i boosted it i rarely brought the rpms about 5-6k

but when the tire spun all through 2nd gear i would tend to redline it at about 6800rps

@PattyWaggon93 hehe mine dont stop before they hit 7500rpms :)

@solveg18 my car at a factory tune never had a rev limiter or speed limiter

i tuned in a rev for 7k cuz hitting second gear or trying to launch my car had a lot of trouble sticking

@watcbd this engine is what's called a non-interference engine hence the timing belt brakes there would be no valve damage or to the piston.

Drop in a Cummins 6.7 L and then the noises will be justified.

what kind of turbo is it? is it a kit? and did you do anything else to the engine after installing the turbo or just leave it how it was? thanks!

@PattyWaggon93 My car is like that but worst... Problem is i can't find a damn cam gear for my 89...
