anyone had a camshaft failure? I had a customers' car come in this past week and #2 intake lobe was cracked and loose on the cam tube. The dealer parts guy told me they hadn't seen a single cam failure yet
Wow, thanks for the info. That is amazing. I've seen camshaft with hole drilled through in the middle, but I don't think I've ever seen one where lobes are pressed in. Things I learn everyday!Fiat is using a cam that is a hollow tube with the lobes pressed on rather than a solid piece with ground lobes. When the car came to me it was full of oil but the customer told me he had added oil. The lobe failure doesn't appear to be oil related though. I'll post pics after I get to the shop today
Yeah, really. I mean, hollow cams I have seen, most racing engines have been using them for a long time. I still think they are super sexy. But this pressed lobes are totally new to me, I just didn't know anything about it. So fascinated.Hollow cams have been around for ages. As for a tube with pressed on lobes, it's becoming the new norm. There are plenty of engines out there that are like this. It's just that nobody knows, thus they never worries about it. There are plenty of other things in various engines that if people knew about, they would lose plenty of sleep. At least this is not like the old days where cams would wear out or a major victory to get a motor to 60K before it needed to be rebuilt.
Just to keep this thread going and all of you up at night:Pressed on lobes.......bah!
At lest they could weld them on?
Something other than press fit?
