good job. I guess you decided not to degree the cams. If you ever remove the timing cover you should definitely do that

looks good

Great write up! It will help a lot of people in the future. I didn't think blue & red would look very good together but I does give them some pop:cool:

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

Great write up man! Alot will appreciate this! :-)

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

still cant get my drivers side cover off :( this sucks. Putting the headers on the car was a hell of a lot less frustrating.

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

Did you do these?
Take the motor mount nut off on the drivers side
Back off the passenger side nut
Tilt the motor quite a bit
Disconnect the sensor on the brake reservoir
Bend the oil dipstick towards the drivers side fender
Take off all the bolts holding the covers on
Take off the firewall clutch adjuster (either factory or OEM)
Take off the bracket that holds the power steering reservoir in front of the drivers side cover

Once you get the cover to clear the brake booster, its still won't come off all the way. Once it clears the brake booster, lower the motor a bit, and then you have to wiggle it on out.

Or just remove the brake booster. It is not that hard and 30 minutes tops.

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

agree........THAT IS WAY easier that way

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

Maybe I am just stupid... :SMASH: I still have it unbolted actually, but I wasnt able to pull it completely away from the fire wall. It was real tight and didnt want to come out enough for me to move it around.

Ill get a second hand to work the jack and see if I can have better luck on my next day off

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

Did you disconnect the brake pedal from the booster? If not, it just unclips. Also disconnect the two hydro lines and vacuum line up at the boost along with the two brake lines under the booster and the single electrical connector at the resevior.

BTW when I mentioned that I take it out, I mean I take it out, not move it out of the way with the lines still hooked up.

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

Sorry it took me so long to get back on thats my post on SVT that your quoting, sounds like you got it back together ok and running.


BTW you only have to remove the brake lines you dont have to remove the pressure lines from the pump.

I have heard about this key way issue but I must have had 98 cams because I had no issue with reassembling it.

also what tabs are you talking about on the chaine guides???? maybe Im just confused????

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

Keyway issue is only with 96-97. And the cam gear doesn't go in the same way on each side, on the drivers side it is flipped, so the keyways doesn't bind and fits flush. And the passenger side it needs to be grinded because it doesn't seat on the cam properly and binds up, and you will break it if you torque it down.

The chain tensioner has orange plastic chain guides. The guides are partially held onto the tensioner by two small fittings, that are really cheap and break easily if any side to side force is applied. Maybe in a engine with less heat cycles they aren't as brittle, but with 90k miles, they were very brittle.

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

alright, got the brake booster out and both valve covers off. Is there a specific way to make **** sure you dont skip a timming tooth? Are you supposed to pull the cams as the engine stopped? or turn it to TDC cylinder #1. Thanks, im trying to figure this out

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

I used wires to keep the tension on the chain taunt. I also used white out to mark the timing gears like crazy to make sure I could tell if it moved.

Dyno tune for E70 is happening on Friday :) So dyno numbers coming soon!

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

Dyno up! Car runs great now. Picked up about 22hp peak, same torque. Car pulls really strong up top now.

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

22HP with a non degreed install...
Where's Modularspeed? This is beginning to sound familiar

Do you have a before dyno sheet to do an overlay?

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
 

No. I don't. It was a different dyno and a while ago.

But we did an overlay with another mach one with 5 more hp than i did before the cam swap, and vs the stock cams at 6500 I picked up 35hp over that car.

At 5k though it used to drop hard on the hp, and now it stays even with the new cams. Up top it made a huge differenence

Re: Removing Valve Covers and Installing Cobra Cams - A Complete How To With Pics
