Looks like i am going to need a valve spring compressor for replacing my bent valves. Is there any kind that is better than the others? Or should i just pick up one from ebay? I see two kinds there one is an 8 inch auto engine valve compressor and one is UNIVERSAL OVERHEAD VALVE SPRING COMPRESSOR AUTO TOOL or are there better ones? Also if my valves are bent could it have messed up my my valve seats? And yes the autotensioner went bad.
