Removing Cam Cover Bolts
Looking for some how to info. I have several stripped heads on the drivers side cam cover. T40 doesn't work and T45 won't fit!

Re: Removing Cam Cover Bolts
Those look like combination Torx and Allen Head
I used the T-40 Torx-3/8 socket and apply lots of pressure down on top of Torx socket when applying torque to the Torx bolt to remove. If the Torx bolt head is stipped.......... Appears to me you have to drill (bit diameter of bolt) so heads pop off. Then remove the cam cover and take a vice grips or as some suggest 8 inch pipe wrench to get a better grip on the remaining stud for removal. If the Torx are not completely stripped, you might try tapping the Torx in place then push hard (pressure down on Torx) as you turn the Torx wrench. those are T-40s and you can use a 9/32 drill bit Trying "other" tricks might mess up those aluminum cam covers By the way....you do NOT have to remove Brake Booster to get drivers side cam covers off.

Re: Removing Cam Cover Bolts
Use the T45 hammer it in basicly making the head of the screw T45
Get yourself a low cost hammer driver local parts store or Sears,put the T45 on the hammer driver give it a few good whacks,always works for me. Pete

The trick there is to have a good quality T-45 Torx and once you get it hammered into place keep a lot of pressure on it as you turn. I used the T-40 Torx-3/8 socket. It is also easy to hammer in a T-45 Torx-3/8 socket just using a regular hammer on the socket or the impact driver if you have room. Hopefully the stripped T-40 Torx are not over by the brake booster Last edited by Dynomite; 03-09-2010 at 02:18 PM. |

It appears that scholtmj was just replacing T-40 Torx bolts with new Allen Head bolts without removing the cam covers? Some of those Allen Head bolts look beat on also Last edited by Dynomite; 03-09-2010 at 02:26 PM. |

Two of the damaged T40 bolts are under the brake booster so off that goes. |

Re: Removing Cam Cover Bolts
I've had luck with stripped torx heads by using a flad headed screwdriver that fits snugly into the torx pattern. I then use a pair of vice grips to clamp onto the screwdriver handle and that gives me the leverage to pop the bolt free.
The trick is to put as much pressure on the screwdriver as possible as you're turning with the vice grips. I'm guessing that the cam covers are getting the same black crinkle finish (al la Black Widow)? TomC 'Crabs

I am not sure about anti-sieze on the cam cover bolts? Maybe that is for Stainless bolts in aluminum since they may be more conducive to galling I see recommendations for using anti-sieze on the water jackets (4 bolts each side of injector housing). Anti-sieze on spark plugs also. Last edited by Dynomite; 03-09-2010 at 02:54 PM. |

I'm actually moving to powder coating with some color. The crinkle paint did not adhere well and was only rated to 200F. All the black under to hood was too much as I'd like the motor to stand out. |
