Default Idling Problems and Wierd Stuff in Oil

I'm having some problems with my Samy and I need help! Earlier this year my Dad and I bought an '87 Samy and he drove it home approx. 50 miles and said it ran good. I live on the other side of the state and didn't even see it until he had started taking it apart for various engine repairs. After it sat around all summer he eventually removed the valve assembly and took it somewhere to be redone. Then he, my cousin and I put everything back together. One of the problems with putting it back together is that my Dad unhooked A LOT of stuff that didn't need to be unhooked, which he also didn't label. It wouldn't start so it was assumed that the hoses were not hooked up properly. When I got home I took a bunch of pictures of a Samy in the neighborhood and shared them with my Dad and we finally got all the hoses hooked up right, then it was a struggle getting the right TDC and rotor position before it finally started. But then the idle was really high so my Dad did something and then it wouldn't start again. By this time, my Mom demanded that it be towed out to me because she didn't want it in the driveway anymore. That was the orignal plan to begin with but both my Dad and I had hoped it would be running at that point. So anyway, he towed it out here and I worked on it and got it running but it it was idling high and sounded like crap. I checked the oil and it had gas in it and through a long painful process of trying things and changing the oil (FYI - it was never driven with gas in the oil, just idled for a short time), I replaced the fuel pump and changed the oil for the umpteenth time and I think I have that problem solved. One or two more oil changes, though, to make sure the gas is gone, before I drive it. It is still idling high, though, and it sounds like it's missing, but the most distressing thing is that when I changed the oil there were flecks of an orangish colored substance. The flecks don't respond to a magnet and they are not sharp, but I have no idea what they are. So, the current problems are: idling high; missing; strange stuff in oil. I really hope you guys can help!

Thanks in advance,
Terri

The orange stuff is possibly silicone/RTV used to seal the sump etc maybe?

I've been thinking about what that could possibly be and since there has been gas in the oil it is probably knocking all kinds of stuff loose. I think at this point I'm not gonna worry about it too much unless someone comes up with something else that it might be.

Things are running better now. Here is a list of everything I did, but what made the most difference was replacing the vacuum lines and the rubber hose part of the return gas line that was plugged.

Replaced:
distributor cap
rotor
spark plug wires
spark plugs
PCV valve
fuel pump (diaphram was torn - gas in oil)
fuel pump lines
vacuum lines

I discovered gas in the oil while troubleshooting all of this and changed the oil twice before I got on here and found the solution, so I replaced the fuel pump and changed the oil again, but I think I am going to change it twice more. Luckily it was not driven at all, just idled for short periods of time. Everything seems to be running good now so this weekend I will change the oil and drive a little bit, then change the oil again.

Thanks all!
Terri

glad you got it sorted. Sorry I didn't see this earlier or i would have recommended the hoses replaced for the high idle. Running too lean from small vaccuum leaks and the various systems not being able to preform properly. Looks like you figured that one out on your own though! Don't know what the non-metalic orange stuff was, but hopefully it was just sediment or paint flecks, or maybe pieces of filter elelment. If its a big concern, you can always get the engine chem flushed at a quick lube shop, they're always trying to sell me that service.

I looked at a lot of stuff on here and replacing the vacuum hoses seemed to be a common theme, and I was also REALLY glad to find a thread about gas in the oil and that the Samy hadn't been driven when that was occuring. This forum and all of you experienced guys are a great resource. You've saved me a lot of headaches and probably a ruined engine.
