Well, my d16a6 rebuild is getting more expansive everyday!

The following pics are of the exhaust rocker arm shaft, at first, I wasn't even going to dissasemble the rocker arm assembly, but I got bored.


I'm guessing that the groves that are etched into the shaft (and in the rockers themselves) are not a good thing. This only happened on the exhaust side, the intake side is still nice and smooth. I'm also guessing something like this is not machineable, and Majestic Honda wants $160.00 for a new shaft and 8 rockers, add that to the camshaft, valvesprings, and retainers that I was planning on replacing, and I may as well just get a new head ($624 for a stock rebuild at importperformanceparts.com or apx $1500 for a performance one from Exospeed)

So, is this a common occurance with these engines? the rest of the engine was suprisingly clean (except for a blown headgasket)

Anybody out there have a used set of rockers and shaft that's in good shape? I can get another head on Ebay for $50.00 or less, but I have no way of knowing if it has the same problem or not.

Keep in mind that I'm building this engine for reliability (I want to get another 150,000 mi out of it)

 

Ever notice how the avarage inteligence of replys drops over the weekend on this site? Or maybee I just ask stoopid questions on the weekends. I'll re-bump this tomorrow so the weekday people can answer this.

 

yeah actually i do the board is more dead.

Im rebuilding my d16a6 right now and havent touched that thing cause it looks scary and complex. I hop mine dont look like that.


I think though you can get that machined out somwhere

 

A little *bump* to get some fresh ideas from the weekday folks.

 

Looks like heat and lack of oil roasted that thing. How do the inside of the rocker arms look? At this point, all I think you can do is polish that thing out and check the clearance to see if it is still within spec.

they're pretty deep, I'm thinking that they're beyond polishing, but i guess i could take it down to the machine shop to see what they say

the rockers are gouged too.
