Since its not a brown top with a vacuum advance distributor.
So either way that would work.

3rd Gen ZC Identified by: Internal coil, large distributor, single butterfly TB. Black cam cover. Cam cover bolts on the sides. Small cam pulleys. Inlet Manifold stamped PM7. +7cc PM7 pistons, 43 cc Pent roof combustion chamber. As a "ZC" this appeared in the JDM EF3 Civic and EF7 CR-X, and also in the JDM Honda Quint Integra GSi (DA1 chassis). This is the most commonly produced ZC, manufactured in Japan from end of '87 through to early '91 D-series version D16A8/9 (Euro Civic Si) (sometimes +7cc P29 pistons)

^ Looks like the one he has as the cam cover bolts are on the sides and it has a JDM cam cover plate (you can see the japanese letters on the cover).

He could also use P29 ECU according to this information.

But all of the engines I mentioned make similar power with similar specs and use similar/same casting heads.

if it's a discontinued part you'll have to go junkyard hopping.

OP, why are you killing yourself trying to find an upper water neck with a bleeder valve ??? PLENTY of Honda engines do not have them and can be successfully bled without a bleeder valve/screw... a bleeder bucket can be purchased at most local auto parts stores and this device is extremely effective in eliminating air pockets and bubbles within the cooling system and can solve this issue for you.





I haven't opened a bleeder screw in years... the bucket does the job.

Not sure you read and understood JR's helpful advice. Instead, you instantly reacted emotionally in defense mode, as usual.

It appears you don't want assistance and feel positive advise given is an attempt to troll.

I believe it's time you move along and find assistance elsewhere if you are going to maintain an attitude as seen here.
