On my sixth item I meant engine knock. My car gets almost to half of the meter and I lose a little bit of coolant. My Accord is starting right away now that the weather is warmer. And Ive had the vibrations even before I changed the timing belt. Thanks for all of the replies and sorry it took me so long to reply.

 

The vibration at idle could be if you jumped timing and drove the car for a while especially with that amount of mileage. It happened to a civic that I had. Which had over 200,000 miles daily driver. 130 miles a day. It turned out that the timing was off 4 teeth.(jumped timing) Changed the belt and still the engine ran rough only at idle. Top end cruising improved, more smoother. But since the timing was off 4 teeth had to get to work so I ran it for a while. Turns out I bent some valves in the head running it w/ the bad timing. Got a decent junk yard head D16Y7 block. Put it on and the engine ran better than when I first got it. Wow w/ 280,000 + miles blowing smoke usually happens. If you love that car that badly I would shop for a swap w/ the same block or a performance swap. Good luck.

 

Since the vibration was occurring prior to timing belt work, then I would go with the motor mount.

As for losing coolant when warm, check your cap, or just go ahead and purchase a new one if the old one is cracked (around the seal) or in bad shape.

As for engine knock, that to me indicates timing. I have a little engine knock on my 460, but that is since I took the EGR off and haven't reset the advance curve in the dist., but on the Honda, I doubt that the cylinder is getting hot enough to ignite early and thereby giving you the engine knock or piston slap. Double check your timing, mechanical and and at the distributor. I would do that before anything else, as if you are off on your timing, it needs to be settled first.

 

Car does not smoke though :P. By a performance swap you mean an h22 or something? And I dont know that much to change out a complete engine heh.
