Cam Housing Gasket
Yesterday I was attempted to pull off the cam housing to paint only to find it is a royal pain in the butt to get it off. Doing more research shows these can be difficult to remove and better left along if there aren't any leaks. Well now that I've pushed and pried on it, even though it hasn't come off, oil is leaking out the bottom. Should I finish what I started and just keep banging on the thing until it comes off or just bolt it back up? Guess I'm asking if the damage has already been done to the gasket or not.
Thanks, Dustin

Unless you like fires, I'd replace the gasket. Is there any chance you haven't removed the inner bolts?

That's exactly what happened. I didn't realize there were inner bolts! doh
 Thank you!

Make sure you take the timing belt off the cam too!

cam gasket
I just finished rebuilding my upper motor. Two thoughts on the cam housing. When you finally get all the interior bolts out and start to remove the cam housing be sure to have a friend helping to catch the hydraulic lifters, and mark each one so you get them back in the same order. To re-torque the interior bolts use a short hex drive socket. To get the socket through the cam opening will require grinding down the outside of the socket until it fits through the hole in the cam tower.
Sounds like a great project. Also be sure to pull the cam tower all apart and replace all the seals. Frenchy |

Mike, can you explain what you mean by using a short hex socket? Are you saying to use a different socket solution than what I use to uninstall them?
Thanks Dustin |

If you use a long hex bit when torquing the cam box you will typically not get it torqued to spec due to the bit twisting when under pressure. If you use a short bit you will get more of a true torque value. Unfortunately to get the short hex bit socket (socket part) to fit through the hole in the cam box you must modify either by grinding it to fit, or put it in a lathe and turn it down.
