so what will happen if you just let you VTCs tick? will the fail? what happens when they do fail?

 

AFAIK nothing bad happens, and performance does not change. This has been my experience. My VTCs tick like mad, but the car itself runs fine, so I ain't losing one bit of sleep over it.

When people ask about the noise it makes, I just tell them my engine is always "in VTiCK"!

 

Tell them its a limited edition Diesel maxima.

 

so if nothing bad will happen to the engine and the performance is basically the same then why fix them? is it just because of the tick that they make and you want to stop the ticking?

 

Umm, because there have been cases of the VTCs breaking apart and totally destroying an engine. And they DO make a difference in performance, its just that you become used to the disabled VTCs. When people put new/rebuilt VTCs in they notice an immediate difference from before.

 

But how common are disasters like that? I for one do not have the cash, know-how, tools or time to have this done. And in addition, there are several stories of VTC repairs undoing themselves no long after. They can't be that important if the car runs fine without them.

 

I have read of maybe 2-3 since I've been on here.

 

2 or 3 occurances out of several thousand (?) 3G owners here = enough rarity for me not to fix 'em.

 

With the luck I have, mine will probably be the next one...

 

I think the VTC ticking like a popcorn machine makes my car sound MEEAAAN !!

 

Naw with my luck it would be my max blowing up, and I have a VG!

hey guys just asking a ?....certain small aircraft have an external primer unit for the engines that pumps oil from the pan into the cylinders heads.....my ? is, is there any way to adapt this to help our aging cars…..machine small holes in the valve covers or heads…..just asking don’t flame me guys……

 

An external oiling system?

 

Dry sump lubrication? Sure. Expensive though. But a preluber might work. Thought about one for a few years

Just putting holes in the valve covers won't do anything. Has to be inside the oiling system. Which none of us know should be screwing with

 

Ahh, I forgot what they're called. It just stores about 1qt of oil under pressure and turns on just before start up. Then a few seconds later re-presureizes and shuts off. I think kits sell for around $160. Its supposed to make a huge difference on start up engine wear.
