The TQ wrench strikes again.....you will need to extract and replace that.

 

will jb weld work on the studs? I dont think i can do the stud change

 

No, it will need to be at minimum drilled down and a helicoil added

 

R u telling me that i have to drill into the current stud and take it out?

 

Yes. Or buy a new valve cover, you will destroy the pump if you attempt to use one screw....and that's best case scenario. Worst case you crack the cam or launch the pump off and cause a major fuel leak.

 

I am not a pro mechanic or so but i used the car couple times and there is no leak.I used jb weld to get the broken piece together and also used to hold the stud and pump together.Will put the screw after it cures well.Here are some pictures.I dont feel like i will destroy the pump nor the engine.Did you have any experience with that you are so sure on this?

 

The repaired area has no clamping force on it and when the nut is installed It has a good chance of breaking all that JB weld off. I would say there's a poor chance of that repair lasting very long.

 

Yes and No.I also filled the inside to make connection for broken side.Is it easy to get the stud out and replace with new one?

 

Can someone share if there is any document or video about it?

 

Not really, the pump will have to be removed and I believe the studs go into the upper cam housing by the looks of it. once the pump is out hopefully there is some stud left to grab with some appropriate size of visegrips and remove..I would never drill in that area without taking the valve cover off and covering everything in sight.

If you don't feel comfortable doing that I would strongly recommend finding someone with some experience to do the job.

 

This is absolutely amazing. JB welding a freaking cam driven HPFP that has two studs holding to the cam. Astounding

 

You dont need to tease us.I have only one stud that is the problem and use the jb weld.If it will not work the.l will look into changing the stud

 

Here's an Ebay picture so you can see how drilling in that area might not be a good idea for you.

 

If you run a vacuum there won't be an issue drilling only deep enough to get a helicoil in to hold a replacement. I've done it a few times on BMW valvetronic motor bases when the fasteners snap lol!

This is very similar but I would still encourage extreme caution

 

DOes anyone know why in step 8 the penalty of accidentally loosening the 21 mm nut on the pump is replacing the pump itself? Why isn't just tightening the nut back up enough if it does come loose?
