STRONG word of advice, make sure your shop knows what they are doing with the MZR head. You do not shim the cam buckets, so the valves either have...
Highly unlikely the pistons need to be replaced unless they are actually cracked or broken. The valves on the other hand will need to be replaced...
Just throwing it out there that I’m finally on the Royal Purple bandwagon and I have better oil pressure with RP than with anything else I have...
I just have one question. Did you manage to get any of the fluids into the drain pans or did you just use the floor? LOL Sent from my iPhone...
Tighten better? You can’t really thread lock it because it has a filter inside.
I got her running just to get it out of the garage at my job, but I need to open it up again and redo the valves. The shop that did my head work 3...
Broke everything down over the last 2 days and found out exactly what happened. Turns out the VVT was not the cause afterall. Apparently, my...
My VVT actuator failed and my timing chain snapped. Damage wasn’t too bad — just 2 bent valves, bad VVT actuator and broken timing chain. The...
I have an intake manifold with the runners already deleted that I've had listed for sale on here for the years I was a metal member AND is still...
I had the same wishful thinking. Turns out, they're just as bendy as the OEM valves. RIP to both our engines at the same time.
Also, just for the sake of the build diary, here's a link to the video I made showing exactly what happened to the VVT actuator: Mazdaspeed3...
Valves are bent. Rotated the exhaust camshaft so the exhaust valves in both Cylinder #2 and Cylinder #3 were closed. Pictures speak for...
350+ WTQ is about the stock clutch limit. Beyond that is when you NEED to start looking at new clutches. As for traction, you shouldn't really be...
Well, boys and girls, it's been a little while since I've posted an update on the ol' girl and I am sad to report bad news. The "revised" VVT...
That’s not a similar issue at all. That’s a leak. 14.7 is stoich, which is “perfect” AFR and where you should be any time your foot isn’t on the...
Glad you figured it out. Sent from my iPhone using Tapatalk
Ok, so just for clarification… step 1 is INSPECT and TEST things, not throw money at it and put in new parts you don’t need and see what happens....
The bad one — likely ENG BAR 3. Visibly inspect all of them, test them if you can’t visibly see if one is bad, if they are all good then you have...
Bad ENG BAR fuse or O2 sensor. Keep driving on that “spiritedly” and you will likely blow your engine. Sent from my iPhone using Tapatalk
“Brand new” is just code words for “not properly secured” where I come from lol Sent from my iPhone using Tapatalk
