How To: Mazdaspeed 3/Mazdaspeed 6/CX-7 VVT The Roku Way

Do it all.

 

Yup, do it all. Ask all the questions you have. I and others will be more than happy to answer them to the best of our ability.

 

Should I loosen both cam gear sprocket or just the VVT one, Some say need to loosen both to even the chain tension, other say only the VVT

 

You truly only need to loosen the VVT bolt. The exhaust side can stay.

 

Ok thanks, just wonder the 6m bolt thread on the timing cover has a small damaged on it, I think I still can put the bolt on but not sure it’s can hold the crank pulley just to snug the crank bolt in? If not do u think I still can time the engine ?

 

Make sure you remove all specialty tools from the engine when torquing.

I might need to update OP on that. Its mainly used to keep everything aligned.

You can get a crank pulley hold tool to help hold the crank. That then becomes a two person job. Which it should be anyway.

 

Yeah if you try to torque the crank pulley bolt with that smaller alignment bolt in, you're probably going to crack your timing cover. At best.

 

Yes that exact what I have done before, tried to be smart ass thinking the 6mm will hold the pulley so I can tight the pulley bolt down, ended up damage the timing cover lol

 

Yeah don't do that

 

I read that dont touch the top of the cam follower HPFP, what happen if touched it? I think I damaged the top of cam follower last time I took it out trying to squeeze it in, now I can hear the noise like the cam hit the follower when in the cabin, should I replace it as well? thanks.
