Removing Cam Cover Bolts - ZR-1 Net Registry Forums

Gentlemen,

I am now officially stuck. How the heck do you get the rear (firewall side) cam cover bolts off? The top two are easy, but the bottom six on each side are out of my league.

What ratchets, adapters, and extensions are you using to get to these bad boys? I'm past the frustrated point!

Check this thread in the solutions section.

On the drivers side, it will involve removing the brake booster or undoing the motor mount and jacking up the left side of the motor.

On the passenger side you will need to disasemble the evaporator box to get to the back bolts, not too tough, be careful not to damage the evaporator.

Thanks Rich.

Any idea how to get at the bolts to begin with?!? I can't even fit my socket into the bolt head, much less attach a ratchet of any flavor. Are you using an allen wrench L-shaped torx?

As was mentioned you will have to remove the brake booster or unbolt the motor mount and jack that side up to reach them. Get an impact driver also. The torx pattern can strip very easily if your not careful. An impact driver will get them out stripped or not.

Roger... off comes the brake booster. What about the passenger side?

GOLDCYLON · 11-10-2011

You need to disassemble the Evaporator box, also referred to as the Suit case. Recommend changing to stainless hardware at this time as well

You don't want to remove the booster unless you plan to replace it; it will really have you cursing and you will be a certified contortionist. Ask me how I know? I recommend as suggested to jack up the motor on that side.

You will also want to invest in a new, high quality torx bit socket. If you strip a head of the bolt you will really have some regrets. They are really tough if the first time being removed.

Lemme axe a dumb question...

Won't we be twisting the C-beam when we jack one side of the motor up? Does the motor actually lean to the opposite side, or are you (in fact) just lifting the motor up? I'm sure the C-beam has some elasticity, but just curious to know what if any precautions are taken - or even necessary - when Uz guyz are jacking one side or another to twist the motor.

Man, I am getting ready to pull my cam covers for refinishing. You guys really got me worried about this job. Is it really that bad getting these bolts out?
