Looking for efe valve 81 k10 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Matt Man · 01-27-2017, 03:51 AM

I'm looking for a efe valve for my 1981 chevy k10 that has a 350, I might have to install this back on my truck and I'm having problems finding one. Thanks.

There's a lot on eBay. Might not be specifically for your application but I would think as long as it will bolt up, it should work.

bump any other suggestions? Would like to find a rebuilt or NOS part.

Which style did your truck have? The one with the actuator mounted at the valve or the one with the actuator raise up near the valve cover?

Low style: P/N: 5234815, searchable with results on ebay.

I wonder what it would take to adapt an early model bi-metal spring-actuated heat riser valve?

I don't know which style it had hasn't had one since I have owned it. I might fail my re-test for smog so I'm trying to find one.

I'm trying to find the exact original design to please the California smog lords. I am going to be re-doing the exhaust which will have the original manifolds so I want to put the efe valve back in which honestly makes a lot of sense to have anyway.

Thank you very much guys for the info, I will look into the parts.

Thanks again!

Got a question, I'm confused on how it will look once installed, am I going to need more parts because I think its supposed to look like this.

How old do vehicles have to be in CA to be exempt from emission tests?

In Texas, it's 25 years and older.
