hi everyone my first honda just joined this site as 2 days ago I bought a 2001 crv and today it had a misfire so done a compression test and cylinder 3 has next to nothing and cylinder 1 and 4 had 175 cylinder 2 about 160 but no one does the valves other than Honda can you tell me what other heads would fit the B20Z1 block please all help and advise is needed

 

Local machine shop..yourself.......or buy another b20 head.

 

first do you know if the valves are burnt? why not try to adjust them first before taking the head off

 

Hi yep checked clearances yesterday inlet valves were all 0.005 and exhaust valves were all 0.008 so I removed the head and the 2 exhaust valves on number 3 cylinder have burnt out and one of the valve seats is damaged luckily enough found a breakers yard with one in 65000 miles on the clock just been in an accident written off rear end so had the engine from that collecting it on Monday thanks for the reply most appreciated
