hey guys i have a 90 crx si with a d16a6. i bought it becaus ethe guy said it broke down one day. apon further inspection it slipped timing. i replaced the belt and tensioner only to find out it doesnt have any compression. i did a leak down test at tdc and it blew air out of intake and exhaust ports. / so i assumed it was bent valves. well i pulled the head out and all valves are fine!!!!! any idea's would be helpful thank you :D

 

Did you set TDC at each cylinder and did the leak down test? It doesn't take too much to bend the valve shafts and have a bad seal. They might look good but if they are leaking, they are not sealing.

 

I just means your timing is off. You have an exhaust valve opening when you should be on a compression stroke. Start your timing belt install over from beginning. Hopefully, you have not bent a valve.
