Zmanco Posted August 27, 2009 Share Posted August 27, 2009 My new lash pads finally came in and there's a lot of surface rust. I really only care about the "channel" where the rocker will slide and am wondering if it's ok to just install as they are? If it was a bolt I'd use the wire wheel to clean it off, but for a machined surface that doesn't seem like a good idea. Suggestions? Quote Link to comment Share on other sites More sharing options...
MAG58 Posted August 27, 2009 Share Posted August 27, 2009 Woah, did you buy them like that? I'd definitely have a talk with whoever sold you those, I would NOT use them in my car, that rust is starting to get into the fine machined surface, you would no longer have a constant contact patch between the rocker or the valve and wear on all three would be accelerated. That's just my opinion though. Quote Link to comment Share on other sites More sharing options...
MoNkEyT88 Posted August 27, 2009 Share Posted August 27, 2009 I'd get your money back. Any part like that should be covered in oil when you receive it. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted August 27, 2009 Author Share Posted August 27, 2009 Believe it or not they came from Nissan Motorsports (via a dealer). I don't think there is any other source for lash pads. Quote Link to comment Share on other sites More sharing options...

I hear you, but here's the real issue: there is no other source for .160" lash pads, plus I've been waiting for these for almost 4 weeks and am behind on the build. So I'd really prefer to find a way to use them if it can be done reliably. What do you think about soaking with WD40 and then using some really fine steel wool? It looks to be surface rust only.

sweetleaf Posted August 27, 2009 Share Posted August 27, 2009 Those look really bad. I would exchange them Quote Link to comment Share on other sites More sharing options...
Robert Posted August 28, 2009 Share Posted August 28, 2009 Sandblast, or use a steel brush grinder and see how they look when the rust is of. But as others mentioned, the surface must be smooth, so If the surface is rough, you must use some fine paper to smooth things out. On a side note, I ordered pads directly from Nissan motorsports, and they were very quick to ship out some excellent looking pads.. Quote Link to comment Share on other sites More sharing options...
zxtman Posted August 28, 2009 Share Posted August 28, 2009 I have lash pads in my tool box that are over 20 years old and have no rust on them. Could your lash pads be an aftermarket part made with inferior metal??? I would question the supplier. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted August 28, 2009 Author Share Posted August 28, 2009 Thanks for all the suggestions. I used the electrolysis method to remove the surface rust and then some 0000 wool with WD40 and they cleaned up well. I wish something would go as-planned on this project ...

Could your lash pads be an aftermarket part made with inferior metal??? I would question the supplier. Were they new, or well used out of an engine? Thank goodness for that oil flim "slug" on some of my parts crying to be used... Quote Link to comment Share on other sites More sharing options...
Daeron Posted August 30, 2009 Share Posted August 30, 2009 Wowsers, that looks like crap. How did they come out? One very useful mild abrasive material I like using on steel when I am concerned about material removal is a green scotch pad. Quote Link to comment Share on other sites More sharing options...
Xnke Posted November 19, 2009 Share Posted November 19, 2009 Zmanco, I just received the same .160" thickness pads, and they also came rusted up straight from NISMO. I think they just haven't been oiled, ever. Quote Link to comment Share on other sites More sharing options...

2eighTZ4me Posted November 19, 2009 Share Posted November 19, 2009 They all come like that now. These parts have been sitting on warehouse shelves for eons now. Rust is almost invariably there. I've ordered many sets from Nissan in the past and they're almost always rusty. I just hit them with a wire wheel on my bench grinder and they cleaned up quite nicely. Oiled them down, installed them and have been doing fine for quite some time on several motors. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted November 19, 2009 Share Posted November 19, 2009 Make sure you test the wipe pattern after the install because they probably are thinner than they were originally, after you take off the rust. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted November 19, 2009 Author Share Posted November 19, 2009 Make sure you test the wipe pattern after the install because they probably are thinner than they were originally, after you take off the rust. In my case the rust was really just on the surface. They still measured 0.160" after cleaning with 0000 steel wool. In hind sight I was probably more concerned when I started this thread than I needed to be. But I had ordered some a year before from Nismo and they were in perfect condition so thought something was wrong this time. Quote Link to comment Share on other sites More sharing options...
hunterzed Posted November 22, 2009 Share Posted November 22, 2009 Found this on one of the other forums as well. Some guys might find it useful if you don't already know about it.

Cobra_Tim Posted November 22, 2009 Share Posted November 22, 2009 Clean and check the thickness... They'll be fine. Quote Link to comment Share on other sites More sharing options...
