Has this ever happened to anyone? What were the consequences?

 

The motor will make a weird vibration above 4000rpm. Longterm, I'm sure it'd mess up some stuff, mostly bearings and such.

 

Yes engine vibrates something feirce. starting at 3500rpm and not stopping toward redline.

 

This car list is the third one I have been on that addressed the 4g63. So, I have been reading peoples questions concerning this engine going back to 1990.

Almost twenty years ago, even if you took your car to the dealership, there was a good chance of the car coming out of the shop with the oil pump out of time. Any independent shop could be counted to do the same. Then, over time, more mechanics had nasty experiences with timing jobs and learned. Now, you don't read of it that much but it still happens. There is always the new guy or the first time DIY owner. So, yeah, over that time it has happened a lot.

As I recall, there are six ways the balance shaft can be set and only one of them is correct. So, it is possible to experience varying amounts of vibration. The major consequence I remember reading in numerous accounts was the owner not happy and wanted the job put right.

 

Reason I ask is because my oil pump was out of phase done by a friend (works at a dealership).

It had a FIERCE vibration like you guys said especially closer to redline. A week later I had him redo the job after finding out what it was.

A month later my oil pump went (19k miles on it). It took out my thrust bearings, thrust landing and crank

I'm wondering if over time the "out of phase" oil pump had anything to do with it self destructing.

I learned three lessons:

1. Remove balance shafts so orientation of oil pump doesn't matter
2. invest in a nice oil pressure gauge setup
3. Only go to a trusted mechanic that has done the job numerous times

Six ways? Only two ways I thought. The oil pump sprocket turns a gear which turns another gear which is also the front balance shaft right?

 

six ways????

 

That could be why I get a little vibration at about 4k but it stops at around 5.5-6k rpm's. the first time I did my cams my balance shaft timing was 3 teeth off, it felt like you were constantly on rumble strips haha. I redid it and all the marks lined up (I rotated the engine about 20 times to make sure they lined up properly) but it still has that damn vibration now and i'm not sure what it could be.

sorry to kind of thread jack

 

There is not six ways.

You turn the oil pump sprocket so the counter weight drops to the right. Thats how you know its in phase.

 

This is what happens when you write without checking. The big gear in the oil pump has 21 teeth. The small gear 14 teeth. So the ratio is 1.5:1. In, other words, you are correct.
