pinging/knocking only on startup

[hooziewhatsit]

Hey all,

 

This is my first post and first question here. So far I've learned a lot just by searching for my problem and not finding anything quite like it.

 

Anywho, on the wifes '91 Loyale, it pings/knocks usually at least 30seconds to a minute after being started. It is much more pronounced when it is cold out. During warm weather (or after the engine is warm) it stops knocking almost immediately.

 

Only thing I can think of is a problem with the oil pump. It's cold, has trouble pumping until it warms up a bit, etc. Oil pressure shows up fine though and still runs fine.

 

Had the oil changed not too long ago.

 

If it is the oil pump, I'd like to replace it before it does any real damage.

 

Thanks,

-Dave

 

 

ps, d'oh, figures that after I post I find this:

For some reason I can't get the first link in that article to work?

 

Sounds a lot like my problem, any other ideas if that isn't the case?

Another EA82 with lifter tap! Everything you need to know is probably contained in the other thread that you found. (Don't be afraid to ask more questions though).

 

Good luck!

ya, thats not pinging or knocking its just the lifters pumping up. if it goes away, its nothing to worry about. just keep up on your oil changes

Cool, if it won't hurt anything I'll just let it go.

 

I make sure to let it warm up in the morning before she drives it.

 

I have the skills to do the fix, just not the time or a place to do it. Right now we can't really have it down while it's getting fixed.

 

I have some other questions I'll post at some point :-)

 

thanks

ignore it until it starts doing it when its hot, or at random interavals while driving..
