Raise the car

[GPXSS]

Lyle, I think he's talking about the 3.4dohc, and you are talking about the 3.1. 3.4's dont use cam bearings, just just rid in the aluminum housing.

Dood I don't know what to tell you. Ride height went up after the new struts. No matter what your reasoning is, your wrong - I saw it with my own eyes and the gap between the tire and fender flare increased noticeably. I'll find the pics just to shut you up. And no it's not a bearing.

Ok, fine. They raised your car. They didn't raise mine. Whatever.

Alright, if you don't think that our cams have bearings, then what do they have? What stops them from burning out?

Now, Yes they do have bearings and if you even argue this with me anymore you are a moron. The type of bearing that our cams have is a "Lubricated Plane Bearing" In this type of bearing the cam housing acts as the "Outer Race" and the camshaft acts as the "Inner Race". Oil is then pumped between the race's. This provides the load bearing mechanism and lubrication for the system. This type of bearing is used where the least amount of mechanical parts are required with the maximum amount of load capacity. ie. Internal engine bearings. The main bearings and rodbearings are the exact same design. The only thing is that, one of the race's (commonly outer) has to be a soft material. ie, Brass, Bronze, Nylotron, Babot, etc. and in the case of our cams Aluminum. That's why we install "bearings" in our engines. This material is known as Babot which is a soft alloy. The babot acts as the "outer race" in place of the cast iron in this design.

I hope this explains a little. Keep in mind, I am an industrial mechanic and install bearings that are worth alot more than your car.

You are so lame. Even when your proved wrong rather than acknowledging it you add one of these in
There are cam seals; I have never heard them called bearings. I'm failrly certain you threw in some 'bearing' lingo in the last post just so you could convince yourself right when the fact is that you initially were probably referring to a regular bearing. I'm done arguing. Obviously your an industrial engineer - you can't be wrong... o wait forgot:

in the case of the 3.4L DOHC. the Camcarriers ARE the bearings.

no it does not have your typical "throwaway" style bearings but the alumium case is the bearing.

How the fuck do you expect the cams to turn and keep from seizing if the case wasnt an integral bearing?? LMAO!

we had a machine shop here at work goof up and accidentally "bead blast" a set of catera heads and bead blasted the actual bearing journal of the camshaft journals..
those heads were now junk.
they may not look like bearings but the cam carriers are bearings.

quit your bickering.. End of story.

How did this thread get here? Tryin' to find out how cam bearings or lack of, can get my car a little higher. Which may be a mute point anyway, since I have read some more and found out that headers really don't do that much for performance on this vehicle. Now I'm sure someone will disagree. Show me dyno results. In the words of Paul Harvey..."And now...page 3." (and I have seen a lot of useful information in this post)

No joke... new struts (KYB GR2s) raised the rear of my car about 2"

Ok, let me get this straight, you have a W-body with a rear monoleaf suspension. You replaced the rear struts (shock absorbers), and it raised the car? Shock absorbers only dampen the oscillation of the springs, they have nothing to do with ride height. Unless your old struts we so fucked, they were seized in the down position. Then your suspension would have been "held" down by the struts. Therfore any old brand of struts would have had the same effect.

Lyle

Ya Jackass. Don't talk to me like I don't know what I am talking about. I believe it was you in another thread that posted about camshaft bearings in the DOHC... try again. Yes, the new struts raised the rear about 1.5-2" Do I need to dig up the damn pictures? The old FE3 struts were beyond shot. When I removed them they bottomed with the touch of my finger and stayed bottomed. The KYB are GAS struts, not oil like the FE3 stuff. The KYBs therefore apply upward pressure at all times. Hence, the ride height increased. So ya, get it straight.

Looks like it was JMGTP that caused the thread to go in this direction. But doesn't matter anymore, because I'm sick of reading all the bickering....
