I have this check engine light that goes on and of while I drive. What can be the problem ?
I have to change my valve covers to the original or replacement ones. I have chrome ones now and want to restore it back to original valve covers. Where can I buy them and which ones are correct? Thanks, rollsman4

Hi Rollsman4!
To diagnose your "Check Engine" light yourself, if you don't have a scanner it is pretty easy.

1: Pull your ashtray out. Under there is the ALDL connector.
2: With the engine off/key on. Jumper a wire from terminal "D" to "E". Your check engine light will begin to flash.
3: Count the flashes. 1st sequence should be: 1 flash-pause-2 flashes. This will repeat this code 2 more times. = Code 12
Then it will flash in sequence (3 times) the trouble code that is stored.
Example: 3 flashes-pause- 4 flashes, then it will repeat this 2 more times. = Code 34
If there is more than 1 code stored it will go on to next code.
If you get a code or multiple code #'s, let us know what they are (if you don't have a chart) and we can tell you what the problem may be.

Valve covers. The correct ones are made of magnesium and have a black finish. There are aluminum repro's that you can make look like the originals. Or you can keep an eye out on Ebay for a set off of an '81-'82 vette.

Hope this helps!

Hi Sarge, thanks for the fast response. I hope to find time this week to check the check engine light.
As for the valve covers I believe Paragon and Mid America list them as OEM replacements. Would that be acceptable in a Judging situation? I was told by one of the judges at a corvette Show in NJ that I should replace my chrome Valve covers. I know I will never Go for NCRS judging, but for the local shows I will.
In fact Mid America has GM written in the description.
( Black Aluminum ). I want to register for the L81 registry, how do I do it?
How can I find out if there are mechanics in New Jersey that knows how to work on Vettes?
Take care and thanks for your help, rollsman

You should have a email with the hyperlink. I sent it earlier today.
Take care, Sarge

Hi Sarge, I never received the email. Sometimes this happens. Would you mind resending it? Thanks very much,

Re-sent. I had sent it through hotmail.com instead of yahoo.com. Sorry 'bout that.
