Guys, yesterday at the junkyard i found a '90 240 sedan with a B230F and only 97000 km's on it. Was smashed up, so obviously written off. Anyway, I was out collecting valve shims and decided to buy the whole camshaft ($20), since it looked very good. I also bought the throttle body ($20) and the IAC valve ($10).
Here's the problem: I have a '91 740 (B230F, NA), and the camshaft appears to be exactly the same as mine except for there's a roll-spring pin inserted into the end of the camshaft where the distribute shaft inserts into - so you can't run the distributer off of it. I can't think of a good way to pull it out. So is it worth it to keep it?
Regarding the throttle body, it appears to be open, just a hair, when "fully closed", and I can't feel the faint click of the sensor tripping when I work the throttle on it. I wonder if someone adjusted it because the IAC valve perhaps wasn't working. Seems wierd that would be the case with only 97k km's on the car. I wanted them because I thought they would be good, with so low miles. Maybe I should ditch both those items.
So I'm wondering if I should just take all that stuff back, or maybe go whole hog and grab the whole head next weekend - assuming I could convince them to sell me the head for the marginal cost of the head minus the camshaft I already bought. Any opinions? I would appreciate the input. Yes, I've read on here that camshaft lobes generally don't wear, but I'm not so sure about that. And, not only do I not have a dial indicator gauge to check them, but I don't have the oem specs for the lobes to know what they should measure.
