ok so i bent to two valves on my b16 head, so i picked up some type r valves for the head, gave the head to my boy and he swapped the valves and i am still gettin low compression in the 4th cylinder, now how did i bent the valves? i blew my lsvtec and i noticed valve marks on the piston and cracked sleeve, cracked piston, and threw a rod lol so i bought a b16 block mint so i slapped the head on the block and started it up and i was ridin on 3 cylinders i did a compression test and on 4th cylinder it was 60 so i gave my head to my friend and he swapd the valves and still the compression is 100 wat the f*** can be wrong?its not the block the other three cylinder # where 200ish PLEASE HELP IM SOOO CLOSE TO SELLIN IT!!!

 

did you face the valves and grind the seats

 

yes i did

 

anyone esle

 

does the motor smoke at all?

 

Is the head warped at all? After you bent the valve did you check the valve guides or anything to make sure they werent messed up?

 

well i did not do the work myself, should i take the head to the machine shop and ask them to check it out for me? im riding on only three cylinders and as of today the car is off the road again.

 

 

bump

 

ur piston rings on that forth are gone i got a brand new type-r bottom end from acura it wouldnt start so i did a compression test and it was 60 across the board b!tched out acura they sent me new rings n gaskets put it all together i didnt even mess wit the head it was freshly built and it fired right up.

 

i will let u know wats the deal, i did a wet compression and it was 150 instead of 100 but i still dont understand why im drivin on three cylinders maybe bad dizzy
