Guys, this is the second time I've had to deal with this so I thought I'd share this time just in case there is someone else that has the unfortunate experience of this in the future. There is quite a few of us running high HP and torque now-a-days so I figure the more amount of tech we can get out will just help us all.
About 3 months ago, just after my car went into Failsafe mode from breaking a pin in my MAFia, I could hear a rattle in the top, passenger side of my of my motor. I broke out the old screwdriver stethoscope and pin pointed it in the front of the head and began pull the valve cover and this is what I found.
I was pretty relieved to find the tops of the bolts still in the valley in the head and not disappeared down a drain back hole. Just some light rubbing on the chain and gears (enough to polish them) was the only other damage. I removed the cam gear bolts, zip tied the chain to the gear and slid the gears off about half way, just enough to be able to **** the tensioner sideways and started drilling.
A couple hours later I had the bolts extracted and I drilled the heads of the new bolts for safety wire just in case, in the unlikely event, it ever happened again......lol. I got the new bolts installed and torqued to the Ford specs and then safetied them.
I put it all back together and changed my oil, started the car to let it warm up and then chainged oil again. All was well.........Up to last night and after a pass, the same chatter came back. Keep in mind, my car hit Failsafe last weekend about 4 times due to the Supercharger Bypass valve being completely destroyed. :xpl:
This is where I'm at now. Notice the difference in the position of the tensioner in both pics. At least the safety wire held the bolts in the tensioner this time.
I cut the safety and pulled the bolts right out.
Tomorrow I'll drill them out and I'm going to over size them this time and possibly stud it this time. I'll update as I progress.:beer:
