Disassembly begins.......


It doesn't look too bad.....




but since I know nothing of this head prior to Saturdays's delivery..... I''ll be as observant as possible during disassembly



I began on the exhaust side... the cam comes out easily enough...




and I'm seeing more crud as parts are removed, below shows the underside of a cam cap, and the exhaust side oiling tube... both show a fair amount of build up




Removing the intake side oiling tube shows a fair bit more crud that was under the tube...




I should be saying at this point that I'm following this post for disassembly - http://www.sr20-forum.com/ve/219-how-install-cams-springs-retainers-ve.html


So following the above post, I remove the 10mm Allen plug......



eeeeew.... quite a bit of sludge here..... its a good thing this head, and all the hardware are getting cleaned, the head will also get pressure checked.


With the plug removed, the small bolts holding the rocker shaft removed, now the rocker shafts can be removed, freeing the rocker/VVT assembles for removal.




Once the shafts are removed, and the rocker/VVT assemblies removed, valve removal can begin





all the exhaust valves are now pulled, and a fair amount of crud can be seen




I move to the intake side, and finish disassembly....




Now, the rocker shafts are under the head, and they are resting on the rocker/VVT assemblies in their own baggies, on the right side of the block holding the valves, are the valve keepers..... So my question to you (reader) is... what is in the small bag on the left side of the valves, and how many are there??



More to come......

Valve spring seats, two per spring set. You do the math.

Looks sludgey.

close.... but 2 per spring would mean 64.... 2 per valve... would be 32

mhm, VE have dual springs, not all SR20s do but RR and VE sure do. Ever get a 54C cylinder head, yet?

Nope... from the few photos I've seen of the 54C heads, I believe the VE ports and bowls are superior... You also can't beat the secure method of mounting the rocker/VVL assemblies in the VE
