Camshaft bearing cap broken

So I was installing my new mutha thumprs and I accidentally broke the front cam cap and now I don't know what to do... I'm not sure if ford sells them individually. Should I try to outsource one or go to a machine shop first and see if they can fix it? My car is sadly down until this gets fixed.

Looks like this guy had the same issue and had it welded back together. Problem with this source is that they never returned to update the thread. I would definitely talk to a machine shop.

Cam Bearing Cap! Need Help!!

The torque specs are 89 in/lbs. You can ask fullmetal7777 about the difference between in/lbs and ft/lbs.

As a side note, it would be helpful to future people searching if you included pictures and kept the thread updated. Too many people have unique issues like this and find relevant threads with no resolution or conclusion.

Good luck! Keep us updated!

I think you have to pull the whole head. Those cam caps and journals are line- honed.

That's what I was thinking too. The cam towers are not replaceable like the TFS 2v heads. Even if you were to try and get it welded, there's no way of machining it to the proper size without overboring all the rest of them. If there was a way to overbore them and then put bushings and then line hone, that would be a solution, but the cost involved is way too prohibitive to be worthwhile. You'd be better off going to a scrap yard and pulling a good low mileage head. F150 or any other 3V 4.6L application should interchange properly iirc.

So I went to the machine shop today and he said the same thing that he would want the head but after he looked at it it was an easy enough weld that he thought he could fix it and I think he did a good job with it. I'll send you pics in a bit. I'm getting ready to see how it fits. It didn't screw up the bearing part at all. So I'm keeping my fingers crossed!!!

Another question I have is why is the timing chain resting up on the head? I have tightened and torqued all the bolts down and have just the valve cover left to do. I'm unable to get pictures uploaded for some reason.

What do you mean resting on the head? Like there is no tension on it, it's just laying there slack?

No it's tight. But on the drivers side where it's coming up out of the timing chain cover and over the cam phaser it rubs very slightly. But everything is lined up perfectly

Minus that obviously

That seems odd. Did you put the cams on the right sides? I know one is shorter than the other but I'm not sure if you can put them in on the wrong sides.

Defiantly possible the cam is in on the wrong side. If it's the shorter cam it's going to pull it closer to the head I would think.

Which side has the shorter cam? I thought the passenger side did?

Alright so thank you guys so much!! For everybody else:

ATTENTION: Do not install your cams on the wrong side! It's easy to do and just be careful of which one goes on which side.

Besides that I am buttoning up everything tonight and going to start her up tomorrow and hope she runs good!!

Here's the broken cam cap after I had it welded. It's ugly on the outside but it looks good on the inside with no rubbing on the cam at all.

And this is what happens to the timing chain if you install the cams on the wrong side :S

The [img] links you posted were messed up and the pictures wouldn't display. I fixed them in my quote. Thats what I was asking if it fixed. Glad you got the car sorted out and this headache is over. We had one member spend a few with problem after problem getting his sorted out.
