I'll probably be doing this soon. For you guys that did it yourself, about how long did it take? I don't really want to pay the dealer to touch my car

There is a how to by @Rokusek;. It's pretty in depth. Cams are not marked for timing so many shops have bent valves trying to do it.

The tools listed in my OP where made by a guy in NC, he had them to me in 3 days after i ordered them. this is an easy job but its very in depth.

Thanks for the Mention @Raider;

HOW-TO VVT

[Raider]

If you have purchased from Street Unit, you missed the threads about them being shitstains.

Take it to the dealer. This is not a shade-tree job.

Oh you could? Got the timing tools? Know the cams are not marked for timing? We do have the how to posted, but even experienced mechanics have mis-timed these engine.VVT is no more than $1200 via dealer. 70001 miles or 84 months and 1 day from sale date-out of warranty.

@Rokusek's write up is gold! Good stuff. Thanks again!
I got my kit from @EdgeAutosport.com.
Good guys, both!

should we always replace the VVT actuator along with the chain and tensionner or is there a way to know if there is any issue with it ?

[Raider]

Since in there, yeah.

[season_of_ages]

In regards to upgraded parts, is there a complete list? I happened across a thread that mentioned the DCR VVT and that's definitely something I'm gonna look into, now that I wanna piece together a kit. I've only started looking into this after giving serious thought to the fact that my engine has over 120k on it. I don't wanna miss a thing!

The new version VVT, would that be as good or better than the DCR VVT?

I haven't read of any failures of the new design VVT from Mazda that we installed correctly. I don't remember the time frame exactly but I believe the DCR was released before the new VVT was released. I know a handful of guys got on and bought the DCR and to my knowledge none have failed.

I emailed DCR yesterday to see if they still give a credit if we send in a new core. If they do I'll send the one I ordered in and have it "upgraded" just for peace of mind.

If they do not offer the discount I may just run the new Mazda version. Idk if 250 dollars more is justifiable.

Edit. So DCR emailed me back and they no longer offer the credit for new VVT core. If you send in a new core the price is 200. If you elect to have them supply the core its 250.

Does the Gen Pu VVT Chain also need to be replaced at 60k?

Idk if the pu's have the same issue. I would assume that they would not be affected. I believe the recall for this came out before the pu was release. But don't take my word for it. The chain is not normally a service item. Should be good for life of motor.
