I've got the heads off my '89 for a valve job. I am tearing down the head before taking it to the machine shop. The book, and the chiltons on-line says to remove the cam seal and then remove the cam. Is there a step I'm missing? Everything is apart, but I cannot seem to get the cam out.


Also, I'm really torn about getting some performance cams for this thing. I really want to do it, but then again its just my winter car. It looks good, and I'll have it for at least another year.
Anybody have suggestions and maybe some links to good cams?

On the back of the heads you will find an access plate. Take thos three bolts off and remove plate. You will find the retaining bolt for the cam shaft. remove the bolt and washer and the cam should slide out the front. Good luck

 

had the same problem...struggled with the cam and then realized there was that one retainer bolt behind the plate...I was like

as for choices of cams...Nismo Euro and Motorsport 260s are a affordable and decent choice for a standard bolt-on automatic VG. you could go more aggressive, but you say this is just a winter beater for you so no real point.

Yeah, I saw that bolt. I was running out of time so I didn't go any further.

I'm guessing I'll call Motorsport tomorrow. I'm looking that these:

do I have too many miles to do cams?

 

is there any company that makes performance cams for the VE?? sorry but i didnt feel like searchin after i read this thread

 

I don't see why...as long as your valve train is solid you should be good to go, have the mechanic examine the components very closely. I had my spare heads acid bathed and purchased new lifters. all the remaining OEM components I planned to reuse. other than that as far as head preperation I only had planned on replacing the valve stem seals and of course new gaskets, then slap in cams and drive off.


as for VE cams, there aren't any(one advantage of the VG over the VE)...of course you could have Crower or maybe Web Cams make you a custom regrind or new billet set, but being that the VE has 4 camshafts, good luck with the bill, it might be some $$$!

 

damn... thats what i thought... oh wells, i wasnt planningon gettin any right now anyways, i jus thought id ask

 

You could have Crower or Web do a custom grind. And you don't have to do all four. You could get good gains just from doing intakes or just doing exhaust. You would need adjustable cam gears in any case and I haven't seen any of those available for the VE either.

 

I talked to the Motor Sport guys, and they had no clue about putting thier cams in a Maxima VG30 head.

Is the '84-'89 VG30 Z head really the same?

 

same head...I've seen Z31 aftermarket cams done on 2 VG Maximas with no trouble. make sure they know you want the N/A cams. you have to realize they probably never really sell these to Maxima drivers so this might be kinda surprising to them.

 

The cams are the same basically from the heads down both engines are the same Z31/maxima.

 

all right then. I'm ordering right now. brb

 

done
