Timing off because RD Motorsports

[Moose_Speed]

Hey guys. Having a few problems with my car. Had RD work on my car and have a few issues. My car gets 0-8.05 knock on part throttle. Goes away under full boost. Have trouble code P0016 crankshaft camshaft correlation. Have had new chain, VVT and tensioner installed. Paid to have done. Was then told I needed a cylinder head. Sounded terrible. Replaced head and reset timing. P0016 was never remedied by RD. Code keeps coming back. Also my breather hose from the valve cover to the cylinder head is missing. New plugs put in and set to spec. Thanks ahead guys. New to forums and such

P0016 is crank cam position correlation. So sounds like a timing issue.

I'm no expert, and I'm not sure how the breather hose will affect things, probably not well. But...

I had a similar problem a while back. Car started fine, ran fine. But if you got on boost from 2500 to 3300, it would pull timing like crazy and bog down. Once it got to 3300 the power would hit all at once and it would pull. Turned out to be the engine being improperly timed. The intake came was off by a significant amount. It had the tensioner and vvt replaced before I bought it, so someone didn't know what they were doing putting it back together.

The first thing I would check is the crank position sensor, since it's easy to check. The line needs to line up with the 20th tooth back counter-clockwise from the gap in the crank pulley teeth.

If that checks out fine, it could be your cam timing. Checking timing isn't to bad, it involves pulling the valve cover and setting the engine to top dead center on cylinder 1. If the slots in the ends of the cams don't line up, it's improperly timed. It is possible to time the cams without doing the crank, or removing the chain cover, but, you have to ensure the crank pulley is properly set using a TDC pin. If the crank is off, the whole job needs to be done. Timing without pulling the side cover involves pulling the cams, so....it's involved. I managed it, but it wasn't without challenges.

Not trying to scare you, but it sounds very similar to my problem.

You need to get the timing redone. It's off a tooth or two.

Thanks man! Sounds like all my symptoms. Thanks for taking the time to explain. I'm new to the Mazda platform and was unfamiliar with this set up. I bought the tools and I had just replaced my cylinder head.

I had checked my crank sensor several times to tooth #20. But originally my crank sensor never matched up with the 20th tooth hence my code I guess.

I had ordered new cam and cranks crush washers and new crank bolt. And I will probably pull the timing cover and recheck it all. I was in a rush originally cuz I had my car in a friends garage.


I really appreciate the help. I owe you a beer! Probably work on the timing next week. Just trying to get the car running good, have a baby on the way

Sounds like you know what you're doing. I didn't get the friction washers the first time, ended up doing the job twice to replace them, just to be sure.

I have access to all data at my work. Will probably use that. Problem i had was all the DIY videos or posts have pieces missing. I work at a dealership working on benz but it feels different when its your car lol. Will keep you guys posted and try to post pictures. Thanks again man
