I went to perform a valve adjustment and the exhaust valve on #4 wouldn't tighten. I got frustrated and called in a travelling 914 mechanic.
The screw was binding in the rocker, but he got it tightened enough to try to adjust. It wasn't moving while turning the engine. I was left with instructions to pull the rockers and check the pushrod as it might be bent. I pulled the pushed out, and it looks pretty straight to me, so he said to pull the lifter out with a magnet and inspect it. This is where I'm stuck. I was having trouble with my extendable magnet extending and collapsing while trying to pull the lifter out. I bought some new magnets, but I'm still not having any luck. The mechanic said that it takes some finessing to get out. Is there a trick to it? What makes it worse is that I have been using one of my boss's cars in the meantime, but they're selling the business (closing on sale Wednesday) so I need to give the car back. I'll get the mechanic back over here soon, but going on my knowledge of the car, if the pushrod isn't bent, and if the lifter turns out to be OK, then it won't be something I can fix over the weekend. Help... (IMG:style_emoticons/default/unsure.gif) |

Another thing you can check now: Since the rocker arms are off (I assume you removed both sets?)
are the valve stems sticking out from the head the same amount? If the problem child is now shorter than the "good" one then you are dropping a valve seat and the valve is being held in too far. If you had a leakdown test kit, you could pressurize that cylinder through the sparkplug hole and see if you hear air escaping from the exhaust. |
