I finally got my most recent purchase up on the "big jackstand" and checked out the structural bits. There is some damage. Like it ran over a median or 10 ton bouder, but I can fix that.
The damage to the underside included tweaking the engine tins (both horizontal and vertical) about an inch up and an inch left on the driver's side. So the engine may have / must have taken a hit too. My biggest concern is the "clacking" sound the engine makes. I started it up just fine. It idled fine for the 20 seconds I was willing to let it run with all that racket going on. Then I shut it off and started running through the possibilities. Needless to say, most of them are not good. Gerbil with a jackhammer was the first one to come to mind. Just kidding. My question is, where should I start to try to find the source of this sound? Thanks, Dawn |

Before you strip too many parts off, take a good look at the push rod tubes too. If it's idling fine, the valves may be working OK, just a lot of racket from the pushrods banging on the inside of the tubes... Even with a bent pushrod, the valves may open enough to keep the engine running, but they would be slamming shut due to the bent rods.
Good luck |

And the winner is...

I checked everyting but the crankshaft (sorry Sir Andy, I couldn't bring myself to drop the engine yet (IMG:style_emoticons/default/sad.gif) ) It turns out, the oil level was a little low and a little thin. Don't know what weight it started out as, but by all estimates it was at least 1/2 gasoline. (IMG:style_emoticons/default/huh.gif) An oil change and a few minutes of running totally eliminated the clacking. (IMG:style_emoticons/default/smile.gif) So now I have a new question... What would force that much fuel into the oil? Possibly the lack of a fuel pressure regulator? Thanks again!!! Dawn |
