Sorry if this not related to the thread, I think the cam lobe on my engine is not looking good, Im not sure what cause is, maybe last time when I take the head off and put them back together I did not really a good job? Thanks for the input

Maybe I will pull the pump out then take a photo the follower, the video doesn’t justify enough the sound it make when inside the car, especially in cold weather. Sorry if this off topic but any chance the 02 sensor can fail the wrong reading without through any code? I noticed with the obd2...

Ok, Do I need to remove the pump housing to take out the cam, or just the pump itself

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. The part...

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

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 ?

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

Ok thanks. So I should replace the VVT, the chain, the tensioners, washers, guides, the oil chain and sprocket doesnt have to replace right... Maybe I will do it in a month a so, I live in Aus and not have to order part oversea, the dealer here quote a crazy price for parts lol

Hi Im about to do the timing chain on my cx7, just have something wanted some advices...thanks My cx7 is 2011, I assumed its has the revised VVT sprocket, Is that absolute necessity to replace the VVT? Will it make the engine less noisy? I can see my chain stretched. I plan to replace all the...

Thanks again. I have an oil leak near throttle body, does that mean the pcv valve stuck?

Yep I already tap a new bolt on it, just dont know why its happen cuz Im preparing to do the chain, really dont want it happen again...

Hi guys, I want to ask for another thing... Last time when I replace the engine mount near the timing chain, when I try to put it back it wont go back line up with the bolt, it stay very tight toward the cabin side, I have to ask another 2 person pull it back just barely line up with the bolt...

I might just do a flush anyway. Does this have anything to do with the oil cooler?

Should I do another trans fluid change? the radiator changed about a year ago, so maybe from the old one that leaking.

Could it be the oil cooler, I heard that some of the mazda oil cooler does have trans fluid and coolant run thru it, I noticed some leak near the cooler as well
