Hey guys,
i had some trouble with the car the other day and ended up running a compression test. dont recall the figures right now but basically cylinder 1 was way down on all the others which were very similar. Pulled the rocker cover off and found that the push rod had slipped out from under the rocker arm. the rocker arm (roller rockers) looks fine but the push rod is slightly bent. pulled the rocker assembly off the 1st cylinder and ran a compression test again with some oil in there, still no compression. a few questions as i remove the head:
1. if i need to replace the valve, does that mean replacing all valves? could be expensive!
2. are all valves considered equal, or are some better than others, some bigger, etc.
3. what else will need replacing?
4. what caused this???
in case it helps, the motor is a 308 with yella terra stage 3 heads (not sure what that means exactly), it has roller rockers, solid lifters and a cam (not sure which one), springs are yellow so maybe YT also but unsure. nothing known about anything else. everything appears clean and in good condition with the obvious exception.
thanks guys,
Paul
