Ok, I have a 1990 civic dx with a d15b2 engine. I am trying to do a head gasket replacement. The head I have is a rebuilt d15b2 head from another car. I am not sure that the head is TDC on the compression stroke. Could someone please do a thorough explanation on how to set up a head that is not on the vehicle please? maybe some pics would be nice. or a link to a walkthru that shows how to set a head up when its off the car. Oh, and yes I am a honda Noob! TIA
Image shows where its at now, it looks like the marks dont line up

 

You all seem so knowledgeable can no one help me with my issue?

 

That camgear is used on multiple models. If your engine is 100% stock meaning a complete D15B2 with matching camshaft, you use the two marks at 3 and 9 o'clock level with the head. The other mark is used for different variants of the D-Series engine.

 

When you've lined up those marks, make sure the 'UP' is facing up as well.

 

Ok so when the 3 and 9 o'clock marks are lined up should the intake and exhaust valves on cylinders 1 and 4 be closed?

 

thanks guys

 

So with the marks at 3 and 9 oclock, were the valves closed?

 

Both intake and exhaust valves would be closed on compression stroke.
The exhaust valve would be open during the exhaust stroke.

 

Pick up a shop manual! All of this is described in great detail with pictures! They aren't very expensive and usually pay for themselves the first job they help with
