A friend of mine has used Oregon Cams to regrind the face on OEM hydraulic lifters to re-use them. He has had good luck with the service. Has anyone else used Oregon Cams for this or have any comments? Thanks.

Have heard of them, but not used them. Did see this from Delta Cam in Washington a few days ago about doing this and what to watch out for.

A lot of the Slant guys use Oregon. Never heard any complaints yet.

Wonder if they're grinding them flat or with the original curve...would require some very specialized equipment.

haven't used Oregon, but had a Machine shop in Smog Jose that reground many a cam and lifter sets. never a failure

Ya know, this is something that is done for every engine rebuild in the piston airplane world.

Lifter resurfacing machine video for those curious how it works.

I appreciate all the responses. I am amazed at how old this technology is and how it seems to be coming back.

Something to consider is at what Radius is the lifter ground? I use Rockerarm Specialist in Redding as they grind on an 80" radius, some others grind on a 100" radius which spins the lifter a bit slower.

Do you have a link, I am getting confusing search results.

I’m waiting on link too, have about 6 sets to do, all 50 or more years old.

The name changed to Rocker Arms Unlimited

I would bet a large amount of money that they don't refinish the lifters themselves
I've been to their shop before they sold the business the first time before the one partner died, I have dealt with Gary since he took the business back and moved it into Redding and sold it again to the current owners, I think they are still operating it, I have not heard of anyone on here using them to refurbish flat tappet lifters.
Rocker arms yes Lifters no

Well, they use the word "we" a lot here:

Lots of talk on A Bodies only about good cam and lifter regrinds from Oregon

looks like they have changed their marketing and parts they want to service

Does the OP want to have lifters reground out of justifiable fear of using the new ones that are out there, or is it due to having obscure parts that can't be bought new anymore?

I talked to TREND they said they can regrind the correct way.

Door #1, fear of using the new Chinese junk that is out there.

Hylift Johnson still made in the USA, and the very last one as far as I can find.

If I was building a flat tappet engine this is where I would start first. Not found in Summit or Jegs ect., but you can get them directly thru them, or thru Hughes. They may sell these lifters to other various cam makers, but nobody selling cam and lifter kits will tell you whose lifters they sell so best to go right to the source. Don't be fooled when cam makers try to tell you not to mix cam and lifter brands. These cam companies don't make lifters at all, they buy them and rebox them and have for years.

This guy has three videos where he got some bad parts and eventually found a workaround for this problem. Salty language warning with this one so letting everyone know in advance.
