So ive read all the accord forms about this problem but now i have to ask what else could be wrong I have a 1990 ex and something's knocking in the head i have tried adjusting the valves and did a compression test. What could it be; im running full sythetic oil and not burning anything nor is any coolant disapearing. Replaced the Raditor,trany, distributor, wires, plugs, and have a short ram intake with all the vaccuem lines hooked up along with headers. if anyone has any ideas or lives near milwaukee let me know.

 

Sounds a lot like a rod knock to me

 

I dont think thats it but how would I check that out, and wouldnt that cause a little bit of a rougher ride

 

no so much. If it's slight it will just make noise and you will notice a loss of power. But if you have adjusted the calves and they are correct that makes me think rod knock

 

higher octane gas?

 

I use 93 octane only and I noticed that when the motor is cold its fine only when it heats up does it start it. could I have over tighten the valves, it was the first time I did a valve adjustment but when i did it on 2 out of 4 cylinders there was no drag with the feeler gauge on both intake and exhaust those were the ones i fixed the rest were fine ?

 

I re did the valve adjustment today and got the car to stop knocking for about 5 miles but now it has returned just not as loud i think im going to re do it again tommrow and see what happens now that im getting better with a feeler gauge or am i just waisting my time please let me know

 

my 1994 accord does the same thing manual tranny. AT 2100 rpms it knock but @ higher rpms it stops, been doin it since i had the car got me stupmed

 

yea I dont know what to do at this point im gonna save up some cash and go all motor H22 and run this engine in to the ground
