I was bored at work today and was thinking... VTCs and turbos fail for the same reason. Ultra Hot oil in the passages ends up cooling and sludging. So why not use the same solution for the VTCs as for a turbo? Am I dumb for thinking this or could it work?

Won't work. But an engine pre-luber might.

Eh worth a try oh well. Oh and Jeff I got the package friday, Thanks

I know . I think I paid for the $.40 delivery verification on your order. Just to see how well it works. Nice for $0.40 huh? hehe

Why won't it work?

How much oil is in the vtc assemblies when it's already running and how much oil is in the assemblies before the car is started?

Well for the before and after oil quantities to be the same is why a high quality oil filter is necessary. b/c the quality of the antidrain back valve comes into play.

I still think the lower o-ring is the culprit that leads to the spring failing! I've got almost 90,000 on the engine and there is no problem with the vtc's. The o-ring was worn at an earlier milage, could you imagine how bad it would be in another 10, 20, or 30k miles. When that o-ring fails to seal completley, then when the vtc's disengage(above 3000rpm) the oil is supposed to stop flowing through the assembles and the spring is supposed to retract the vtc assembly back into place(rotating the cam's and changing the timming), but when the oil still gets past the o-ring it still wants to partially pressurize the assemblies, this is when something goes wrong.

Also keeping the connectors clean.

He is saying that the failure would be caused by lack of oil at start up. Not that the timer it self would not work but that it is to late and the damage was done at start up not "shut off'

Well if the oil drains out of the assemblies, then the oil is now able to 'bake' on, and a cycle begins creating the varnish and possibly sludge. So by using a good filter this can be prevented.

Personally I'm all for a pre oiler (I forget the other name for them). But it's just a cylinder that has a solenoid on it and it captures oil under pressure, so when the car is started cold you can manually open the solenoid and then there will be oil pressure before the engine is cranked over.
