Could be several problems, but I would start looking at vacuum hoses and troubleshoot the EGR valve to ensure it is functioning properly.
I hope you were aware of Honda service bulletin 97-047 which was for blown HG on D series engines. It gives the PN of an all metal HG and a set of head bolts to go with it. I wasn't and ended up having to replace the 1st HG I did on my HF 6 months later. On the bright side, it only took about half the time the 2nd time

After putting it back on the engine idles rough and will not rev up, only bogs down. I have the timing marks perfectly aligned. Cam shaft pulley 3 and 9 o'clock marks in line with top of block and on the crank I have the mark on the timing belt pulley lined up with the arrow on the oil pump/bottom of the block. The TDC mark on the crank pulley also lines up with the pointer on the timing belt cover. I have read that there could be a crack in the head or a piston. I hope not. Have any of you had a problem like this?
