Default new vvt actuator, chain, tensioner, and guides

well, it finally happened- I dropped the car off today with 125k miles for the whole timing shebang! I have been hearing the chain slapping around for a while now, and finally have the extra cash to get it fixed! I should have it back in a couple of days...

Good luck with the repair... but DAMN! You have 125k on a MS3?! My other 04 MZ3 only has 110k miles on it...

Yeah, I drive a bunch! I got the car back today, and it is great! I didn't realize how bad it had gotten; it's like having a brand new car again!

Glad you got it all fixed up. Mind sharing what all that cost? Also, what symptom(s) were you having that let you know that the work needed to be done?

I'm glad , too! The bad part is that it cost about 1000 bucks, including the synthetic oil refill and rental car for 2 days... I knew it needed to be done because I could hear the timing chain slapping against the inside of the valve cover. It was kind of a dead giveaway for the chain being all stretched out. The VVT actuator had been making noise for a while (the mad loud sound for a couple of seconds after startup), and the chain guides just because it was all apart anyway, and only added a few bucks to the total.

Hope that helps!

Mike, you may drive as much as I do. As of 12/2/2011 I have a little over 158K on my '07 MS3. I'm about to have the timing chain replaced, and am researching whether the VVT actuator should be done as well. It does not make the big noise others talk about, but I would hate to have to go back in to replace it later.
I have a quote for just under $700 (independent, not a dealer) for the chain job alone, so i guess the actuator will add another hour of labor plus the $120 part.

Yeah, it sounds like we are about tied on mileage; I was starting to think that I might be the highest mileage speed 3 around! If I were you, I'd go ahead and do the vvt as well, so you don't end up tearing the whole thing apart again...

I thought I had a good chance to be the highest mileage Speed3 in the USA, but I reckoned there could be other contenders somewhere. I remember when you joined this forum back in '07. Do you plan to keep it for a while longer? I'll drive this one as long as it stays reliable.

I had the shop order the VVT as well yesterday afternoon. We'll schedule the work when they have all the parts, so I guess it will be middle of next week or later.
What are the guides? I don't recall seeing that on the TSB parts list.

After that, I should replace the stabilizer end links. They make a lot of racket on bumpy roads now, and I just have to decide whether I want to try myself or pay the shop to do install them.

After that, I might put on a short ram intake so I can actually hear the turbo.

I'll drive it until it doesn't make sense to fix it anymore, and then I'll probably fix it and keep driving it! The timing chain guides are just plastic pieces that the chain rides on. It was only a about 30 bucks for the parts, so I just replaced them since it was already apart. No extra labor cost involved.

Well got a while to go for this hopefully(only 39k right now).

Thanks for the info.

Will look to do this round 125k.

Other than regular and this major maintenance, have you had any other issues at all with the ride?

Just got mine early summer. Had thermostat fixed first 30 days free. Other than that been solid.

Shit jus did a 780 mile trip to Charleston, WV. Cruised bout 80 there an back. Got about 28 mile per gallon with spirited drivin(going round slow folk).

Must say car is to much fun.

This is my DD and plan to keep for awhile. damn thing has all I have ever wanted(Turbo, HIDs, Leather, Navi, 6 speed, and 4 door hatchback). Can fit da kids and still have fun...wooot!

Still workin on kids.
