I have 1998 Chevy Blazer, 4.3l.
I have been tracing down a vacuum leak and it lead me to the PCV Valve Cover. The problem is the one listed is NOT the one that I found!
AA and AZ list item Dorman 47026. This part has "3" vacuum connections. One to the PCV valve and 2 to????

The part I have on my blazer has only "2" vacuum connections. One to the PCV valve and one vacuum connection to to a check valve for the HVAC and 4x4 lines.

Any clue or guidance please.

 

It is a part for multiple applications, as in many different vehicles. You only use two of the nipples and cap the other one off. If I'm not mistaken, some of them come with caps and some you need to snip off the ends of the connections you will use and leave the other one be.

 

Thanks Bert. That makes since, I just couldn't process that last night. LOL I will check it out and just get a cap.

 

Howdy!

I replaced everything from my PCV valve to the PCV valve cover on the intake plenum, including valve cover grommets. Got all OEM parts from a Chevy dealership for about thirty bucks. Ended up being more convenient for the same price, but confident the right parts went in. Good luck.

 

Thanks Balzin...
I got that fixed but it didn't fix my HVAC problem but at least I know it is right now :-)

 

I wish you guys would post where you got the parts, the parts no. , and the cost. It would help the others following on the forum that have the same problem and are wondering. Thanks! Jim
