Compresion test, post results. Then a block check test depending on the numbers from the first..

 

If crankshaft pulley came off (someone failed to tighten retaining bolt), the timing belt sprocket may have come loose from the crankshaft (woodruff key drops out). If this happens valves will be damaged.

Check compression to identify cylinders that won't generate compression. You can also remove valve cover and check the valve stems to see if valves are not fully returning to seated postion.

Cylinder head must be removed to repair damaged valves. Suggest having cylinder head rebuilt; damaged valves replaced, all valves reseated, new valve stem seals, head checked for cracks, and head shaved perfectly flat. Of course a new head gasket will be required for reassembly.

good luck

 

Okay, I performed a compression test and here are the results:

1) 0 PSI
2) 0 PSI
3) 165 PSI
4) 160 PSI

Is the next step pulling the head?

If so, what should I look for once the head is removed to see if there is valve damage?

I would imagine a blown head gasket would be quite obvious by condition of the gasket. Is this normally true?

 

Yes, pull the head.....try to be as gentle as you can with the old gasket, it might "show" issues....or once you flip the head over it might be real evident as to the issue.....Check the deck surface for warps....then take the head to a machine shop or buy one from a place you trust-warranty....then replace everything needed (gaskets, seals, hoses, t-belts, wp, ect) ...you are there, now is the time....you don't want to see most of those parts ever again.

 

Your first step should be to get a Honda Shop Manual to guide your work, if you plan to DIY. Check ebay seller automanualsource for a good emanual for $21.99.

Cylinder head removal requires removal of timing belt. You should find out if water pump was replaced when timing belt was replaced, and replace water pump at this time if indicated.

See my previous post for list of things to prepare cylinder head. No short cuts, as you'll probably spend about 6-10 hrs each way for removal and installation. You don't want to do this job twice!

good luck
