how to remove valves

[minivan]

how do you remove valves on the 1.6 dohc non vtec engine?

with the head off and placed on something steady (ie. a workbench), place a wadded up rag into the cylinder dome of the valve set that you are removing. Take an old deep dish socket that is slightly smaller than the spring retainer washer. place it on top of the retainer and give it a good couple of sharp wacks with a rubber or plastic mallet. try not to use a steel hammer, this causes too much impact and shock. The retainer clips should "pop" out of the grove on the valve....wallah springs,retainers, clips and valves are out. A little magnet will help in retreiving the retainers clips. Hope this helps.

how do you get off the valve seals?

 

[hybrid89]

carefully pull them straight off with a pair of plyers.They should not be reused.

the best way to remove the valves is by using a valve spring compressor to compress the springs, no whacking necessary.

head off, only way. for valve springs you can get away with compressioning the piston chambers but it's much easier with teh head off, plus good time to change the head gasket and get the ports cleaned up.
