OK, here's the story. I dropped the engine to install the seal between the sheet metal and the oil cooler. I had the fan, and all the sheet metal off and then put everything back with the addition of the rubber seal for the oil cooler. Now its back in the car and running gud! At idle and low RPM it makes a tweeting sound that goes away at about 2.5-3K. Its not the alternator belt. I removed the belt and it still makes the same noise!
It sounds like rubber or plastic rubbing on something and I have no idea what it is. All I know is that the WCR is one week away and I don't have the time or energy to drop it again even if I knew what it was which, I don't. Any suggestions?? (IMG:style_emoticons/default/headbang.gif) |

This thing is driving me up the wall (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif)
I've observed the fan form one of the heater outlets and it appears to be spinning true to the crank. I sprayed some lubricant in thru the timing hole onto the fan thinking it would change or stop the sound: no effect at all. I took it for a drive and I think it's getting worse. It doesn't go away at speed. It seems to be load sensitive. Say I'm at 3500 rpm in 4th with my foot on the throttle, it won't be so bad. Then when I lift off the throttle the sound will increase. It seems to be coming from the passenger side front of the engine. I even went so far to pull my #4 rocker shaft. I made solid bushings to replace the springs when I built the engine. I thought maybe the clearance was too tight. I machined it down. No luck! People keep mentioning the distributor. I have a relatively new Mallory pointless distributor. Do they need lubrication??? Help! |
