Knock, knock, knockin'

[Knucklebuster]

I have a 93' N/T Eclipse. It knocks like a Jehovah's Witness when I accelerate. Is this a valve adjustment problem, lifter problem, or maybe valve seat issue? I guess it could be piston rings, but I haven't done a compression test. Also, it puts out white smoke when it idles for more than a few minutes, or when you start it up after a few hours. If I can't figure it out, I guess I'll have to put it to pasture, because I'm not being paid to be the village mosquito sprayer.

PS: Thanks for your reply DSMBOB

Sounds to me like a rod knocking. It could also be a lifter b/c hydrolic lifters sound a lot like rod knock when they're bad. If the knock is very consistant, never to miss a beat, it is more than likely a rod.

Watch the movie on my site.
Does it sound anything like this?

Change your oil or just drain it and see if it looks like that...

If so get ready for either a rebuilt bottom end or drop the pan and do what everyone is telling me I should do.

I just watched your movie, and that is what my car sounds like. What do you suggest? New Rods, lifters, and a valve adjustment one time, or something else? Thanks.

i have a 93 Laser RS NT, it did the exact same thing. I tore the engine apart and found 2 rod bearings had spun and were chewed up. With little time, cash the best option for me was to buy a good short block, everything was ok so i rebuilt it that way. I have 10000 km's on it now and runs strong. This also gave me the oppertunaty to replace the 7-bolt engine with the 6-bolt block, hopefully not having to deal with crankwalk.
