Perhaps your GM 4.3L engine has Piston Slap? Piston Slap is common on many GM engines. Especially the 4.3.
My 2001 Safari 4.3L has piston slap in really cold weather. Especially during its warm up phase. For more details, surf: http://www.pistonslap.com/photos.htm
For me, I get my local auto shop to install Synthetic "5-w30" during colder weather. In the summer hotter months, use normal Synthetic 10w-30 oil. This seems to help reduce engine noise...
Hope this helps...

The best way to determine a noise is use a automotive stethoscope because a knocking noise you think may be coming from one place will actually resonate from any where,and a stethoscope is the best way to find out.The 350 chevy engine has a push rod driven fuel pump and it's hard to tell how many people that's been charged for lifter replacement that didn't help the problem because it sounds just like a lifter and it's just a worn fuel pump spring or worn push rod.

First, its a 4.3, V6, not a 350 V8. And had many, with never a pump rod go bad. Thing is, the fuel pump is in the tank, electric. And getting a "ear piece scope" in there is very difficult. If its a half speed always "tick", its a lifter. Piston slap will be engine speed, and a slap on the throttle, will increase it. Pretty simple. 50 years Chevy, 175000 my Astro...do what I said..Rislone...or just live with it until the cam gets "wiped", which is many years. Lose a little perfomance, but not worth any major engine work...

Ticky, Tocker, Stetholooker......Cheap!!

34 years in the automotive racket, I can tell you all that the BEST stethoscope which works and can been thrown at a wall, stepped on, drivin over and has multiple functions is..........: A very, very LONG Screwdriver!! Prefferably one with a synthetic plastic handle and not wood. The high impacts plastic gives a clearer and better resonance picture than wood. Again just my own opinion. I have a craftsman which is 24" and it gets almost anywhere I want. Those "Doctor" Ear type are good if you plan on giving a full physical and a " pap smear", then perhaps that may work well. But for us motor guys, I think most might agree with me that the screwdriver described is the best way to go and usually the cheapest.......!!!! You will be amazed at what you can hear and how clear it is!!

If your compass needs reset, I believe it just says C when it does. You simply drive the van in a tight 360 degree circle and it should reset.

In the first place I was using the 350 as example not as part the problem,maybe you should learn to read before putting your big mouth in gear. DLM1

Some peple don't know how to use the proper tools, yes a screwdriver will work so will a wooden and maybe you could cut off your dogs leg and use it to, but there are the right tools and the wrong ones and you don't have to use a doctors scope they make one for autos in the twenty first century some people just can't understand how to use them I guess.Personally I've diagnosed several knocks with them with no problems as with a screwdriver but sticking a six inch screwdriver down in an engine bay with the motor running sounds a little stupid when you can use the right tool with a 30 inch line, of course that's only my opinion but I still have both my ears and all my head from not using a screwdriver, wooden stick or dog leg. I'm sure your quite an automotive genious but maybe you should update your tools a little more often. DLM1
