I have a few questions for a unfortunate/upcoming Head Gasket removal and replacement. It is on a 1991 civic dx which I believe is a D15B2 engine...

-What all needs to essentially be removed. ie. Intake man, Exhaust man, coolant hoses, sensors, spark plugs, valve cover, spark plug wires, upper timing cover.? WHAT ELSE?

-What all do I buy, ie OEM head gasket (someone mentioned a Z6 one for a little higher compression?) head bolts? gaskets?

-Also check head / block for warpage..

I am just wondering and I can not find a DIY step by step for this, and in my opinion Helms/Chiltons do not cover it all..

THANKS ALL!!! Also where do you recommend buying these parts..?

 

i recently replaced my head gasket on my 91 CRX with a d15b2. I had to remove the intake manifold, but i just took the nuts off the head and pushed it back. the same thing can be done with the exhaust manifold, and the distributor. i would recommend doing your timing belt at the same time, as its easier to get to with the side of the engine with the head off.

you should buy a "head set" from the parts store (I recommend a Honda dealership for a head gasket) along with a timing belt, tensioner, and water pump.


when you do a head gasket, you should ALWAYS have it resurfaced by a machine shop. around here (southern cali) it costs about 50 bucks to get a head resurfaced and hot tanked. its very worth it, and will save you money in the long run.

p.s. i don't have much experience with the ZC head conversion.
