no, seals. the guides are not a seal, the seal seals. the guide is more of a bearing that keeps the valve straight as it travels... its an umbrella type on these toyotas which hardens and does not seal well over time. the valve seal sets down by the spring seat, which is a lower area of the head, so oil pools there when the engine is off. the hot thin oil leaks past the valve seals, down the valve guides, and into the combustion area. if the valves are closed it pools ontop of the intake and exhaust valves, or if the valves are open, it leaks into the combustion chamber.
i dont know how to more clearly explain this, beyond with pictures. -------------------- |
