I have a 1987 Chevy R30 with a 454 TBI and I noticed that there is oil pooling on top of the intake on the driver's side. I didn't have a chance to do any real investigating tonight since it was too late, but I was wondering if there was a common problem with oil leaking on the intake manifold. It seemed to be puddled. I'm pretty sure it isn't the valve cover gaskets because I can feel them on the exhaust side and they feel nice and soft plus they definitely don't leak on the exhaust. Any suggestions? Possibly a PCV valve problem?

I have a 2000 Ford Explorer Sport 4x4 with a 4.0 OHV engine. I bought the Explorer with the temp gauge not working and now its time to fix it. The gauge stays all the way down on cold and doesn't move a hair. I tested the gauge by ground out the red/white wire and the gauge sweeps as it should. After that I thought it must be the sender so I replaced it and it didn't solve the problem. The thing is the harness is a single wire, but the sender I pulled out and the new sender both have 2 pins. I went online and checked the part number and its for my application. I really think that these senders are boxed wrong. Anyone have any advice? Thanks.

The truck has a 5.7 engine and lately its been having a starting problem. Sometimes in the morning it wouldn't start....if I came back a half hour later to try yo start it again, it would fire right up. Now it wont start at all. It has no spark whatsoever. I replaced the coil, had the ignition module checked which checked out good. I replaced the cam sensor in the distributor against my better judgment. The only thing left is the crank sensor, right? Unless of course I have a bad wire or ECM, but I have no pin-out to do continuity checks. Any suggestions?
