Toda Spec C's with somewhere between 6000-10,000 miles of use. Everything is great except the #4 VTEC lobes on both cams. Use them or not?

The good lobes...


And now the suspect #4 lobes:

 

sorry~ no idea

 

then why reply?

 

To get an extra post. Why did YOU reply?

 

haha

then non of you guys know and REPLYed

 

How bad is it on the #4 VTEC lobes on both cams ?

 

When you rub your finger over it, do you feel anything?

 

Depends on how much you getting them for? It doesnt look that bad on the cams in the pic. And its only on one of the lobes per cam?

 

to bitch at him.

i'll contribute...

if you can feel it with your fingernail, it's really bad.

happy?

 

Yes, on the frontside and backside of the "ramp" there is a noticeable groove that run horizantally on the lobe. There is also a very thing metal ridge building up on the edge of the lobe - almost like there is metal "squirting" out the side. If I were to run my finger nail across this ridge I could knock it loose.

Ausmith -who is still curious why both the #4 VTEC lobes show these signs of wear with only 6000 miles. Why don't the primary and secondary lobes show similar wear?

 

Improper Valve Clearances ????

 

If you are buying these cams and you can talk the person down to a cheap price I would probably get them. I think that you can send them to Web Cam and they can repair that lobe.

 

TTT for the Monday morning crowd.

 

Can you have those #4 lobes resurfaced or will that have a negative effect on the contact area. They don't look too bad from the pics, but if you can catch a finger nail on the grooves I wouldn't feel too confident. Let us know what you decide...good luck

 

If there is a ridge build up on the edge of the lobes it means the metal was deformed and you are know out of spec. You are also running the chance of creating uneven wear on the rocker arm if you use those cam shafts. I did not read your whole first post but if you are considering buying those I would think twice.

As for the reasons for such wear...??? Anything that will prevent free motion of the rocker arm is a possible reason. A lack of oil is also to consider.

Do not resurface the cams-
I would advise against, you wonder why???
spinning at nearly 10k RPM-
and to have it break would be horrible!.

get them check by a shop who can do the X-Ray test and see if there are any flaws in the metal and then measure them to see if there is any unwanted ware.

Good luck.

 

Oh yeah,

if you can feel it, it`s really bad.

Soon, they will lool like my OEM cams.... And will f00k up your head

 

Here are a few more pictures close up on the suspect lobes. If you look closely you can see the metal on the edge of the lobes. I'm just ver curious as to the root cause - more for education than anything else. I was told when I bought the cams that they had "Normal Wear" - needless to say I was disappointed when I opened up the box. I speculate that the valve springs had coil bind or that the #4 rod broke not allowing the valves to open.




Thankfully the person who I bought them from is a quality individual. He was selling them for a friend and didn't take the time to examine the cams. He is going to send me my money back, although I did **** him off from coming on a little too strong once I saw the cams were damaged.
