Jersey Posted January 8, 2004 Share Posted January 8, 2004 Hey all. Finishing the build on my cousins L28ET, rockers on, ask him for the retainer springs... he lost 'em Yep, so now i have to find a set for his P90A and just wondered if anyone knew of a good place to get 'em? Also, does anyone know if they're the same between the P90 and P90A? Thanks. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted January 8, 2004 Share Posted January 8, 2004 The springs are all the same, but, is this one of the funky P90A's without hydraulic lifters? Hydraulic lifter heads don't use the springs. You are referring to the springs that go on the back side of the rocker arm, and connect on either side of the rocker pedestal, right?

RB26powered74zcar Posted January 8, 2004 Share Posted January 8, 2004 If it is indeed a regular P90, I have a ton of those springs... just pay the ship and there yours... let me know joel Quote Link to comment Share on other sites More sharing options...
Jersey Posted January 8, 2004 Author Share Posted January 8, 2004 It's a P90A head and it's the retaining clips that hold the rocker arm to the Hydrolic Lifter or HLA. I'm not sure why they're even neccessary since the rocker is cupped around the ball headed HLA but i'm guessing it's some sort of saftey issue. Anyway, i appreciate the replies and the offer Joel. I called nissan and they're actually still available - $1.99/each. So my cousin make a $24 mistake and missplaced them. What burns me up is that they'll show up in about a month or two when the swap is all done! lol. Thanks again. Quote Link to comment Share on other sites More sharing options...

Jersey Posted January 9, 2004 Author Share Posted January 9, 2004 That's real odd. I know they were on there because we (he) pulled them off. Does the top side of your rocker arms have slots in them to accept the clips? Like i said, i really don't see much of a need for them since the HLA holds up against the bottom of the arm and the center part of the arm is held down by the cam? Anyway, weird why some P90A heads with HLA's would have 'em, and i guess some don't. Learn something new each day. The ZXT that it came out of was built in 10/82. I wonder if they ditched the idea later the prodution date ZXT's? Quote Link to comment Share on other sites More sharing options...
Jersey Posted January 9, 2004 Author Share Posted January 9, 2004 I'm just thinking AGAIN about it.... i think he has me thinking wrong and you guys are right... this P90A head didn't have the springs EVER. When we first bought his '78 280 about a month ago, someone used a larger tappet on one of the intake valves, which is why the Z always ran on 5cyl's and we got it so cheap , and we ripped the top part of that motor apart, and i do remember the springs on that N47 head. I bet since it's been about 2 weeks since we pulled this P90A off to have rebuilt, he's confused and is thinking of the N47 head! And to boot, he's got me pulling my hair out looking for them, saying i must have thrown them out! LOL. I will find out for sure if this is the case tomorrow but now that i'm thinking about it, i bet this is the case. I think the memory goes with old age first Sorry guys if this whole post was mis-information. Will confirm tomorrow. Quote Link to comment Share on other sites More sharing options...

Jersey Posted January 9, 2004 Author Share Posted January 9, 2004 Confirmed - he was thinking about the N47 head. This is the first time i ever worked on a HLA head and now i know, they don't use the retaining clips. Thanks and sorry about the post guys. Lock, no idea what you mean?
