You cannot replace one or two cam covers. They have to be replaced as a matched set. Look here in the WTB forums. That's your best bet.

Number one cause is cam timing.
So I went to the shop today to see what was going on. I asked if he could check the timing again and he let me watch as he removed the valve cover. The timing was off and I mentioned that but he said that they tried the correct timing three times but it didn't work so they reset it to what they thought I came in with. I asked if he could remove the cam covers and try again. He reset the timing for the cam markers to line up and started putting the cam covers back on and it made a weird noise. I noticed that the teeth of the cam gears were not splining in and we were actually on teeth to teeth. Two of the cam covers are now cracked, that was the noise. He then got the cam gears to spline and seat properly although the markers seemed a tiny bit off and replaced all the cam covers.

He tested for spark and VOILA! We have spark! Billman is right it was timing all along.

He didn't want to try to start the car as there is a crack on two cam covers. So issue is solved and the car should be able to start.

He said he will replace the two cam covers from a rebuilt s2000 motor he knows of and it should not be an issue. He said he can not order the cam covers individually as Honda won't sell them individually and you have to buy a complete head.

I'm happy that we at least know the car starts now.
Great to hear that you mechanic cares and perused the issue.

I would say, too bad your mechanic is so totally incompetent. If op hadn't been there to set him straight, and notice obvious things the mechanic didn't, car would still be down.

Actually, car is still down due to mechanics incompetence. Now he wants to replace incompatible cam caps. More incompetence...

After doing a little research and from what you guys are saying, the cam caps can not be interchanged. I believe he is getting an damaged F20c (bent valves?). Will swapping the entire cam caps from the damaged motor work (assuming these cam caps are fine)?

Thanks for all the replies. They have all been tremendously helpful.

Yes. Take the entire upper assembly (10 piece matched set) from the bent valve engine and move it to yours. Re-adjust valves and you're set.

You need the rocker assembly as well? So the caps and the assembly are line bored together?

I just wondered because I saw 10 and I'm like, there's only 5 cam caps.
