yeah valve seals, its notorius with the 5sfe go on the rav4 boards. the valve seal cant keep a good seal so very small amounts of oil with drip down eventually into you cyclinder(s) and on start up be consumed.
i have it, sucks. when i have time college and all i plan to replace them and my valve springs with 2jz ones. This post has been edited by x_itchy_b_x: Jun 24, 2004 - 5:19 PM -------------------- |

Same here. I remember reading something a while back that the valve stem seal problem was pretty widespread in all "F" head Toyota engines, but that may have been speculation...

supposedly, im still gunna do sum reasearch before i say sumthign stupid. but yeah the valve stem is the narrow rod on the valve that is connected to the head of the vavle. hard to explain with out pictures lol. if this T was a valve the bottom line would be the stem -------------------- |

oh the blue smoke problem.
My dads s-10 has the same problem, as the engine heats up the valve seals expand and the oil leak dissappers. The sad thing is the engine only has 99,500 miles on it. The only way to fix this problem is to change the valve seals, but this doesnt last very long either because the valve stem seat has worn down and starts to wiggle over time; this causes the valve seals to wear down faster and the leak returns. I had to change valve seals 3 times on differnt cars. its a bitch to do. |

So eventually, would you be losing oil? Because mine does the same thing, and it prolly takes a month or so before I notice my oil is down. My dad says I have scarred cylinders and oil leaks through the scratches. But this seal problem that you're talking about seems feasible also.

well, if the valve seals continue to degrade then you will start to burn oil continously, and you will eventually lose oil.

This seems like a pretty common problem? Is there any recalls on any parts of the F series motors?

Is it just a "ware and tear" thing, or is it caused by rough driving, or both?

From what I have seen are these seals start to harden up over time. When they get to the point where they no longer can seal the moving valve stem, oil gets in.
So I assume its from wear and tear? I dont exactly know the reason. |
