nope. the c-clamp holds the backing plate to the chra. the comp cover is held on by bolts
that o-ring is between backnig plate and cover
unless I'm completely mistaken about what turbo he has

if that's the case, that sucker looks a whole lot smaller (and I'm guessing its prob lighter too), might be a cool mod for us NB2 people.

If you need an 01 compressor, I haz one for sale btw. same size/style as the left one
hello impuls you are going to need the matching mazdaspeed compressor A/C bracket in order to fit the smallerMazdaspeed compressor unit in your NB. The compressor pulley in mazdaspeed compressor is about an inch longer therefore it will not align to the crank pulley , trust me on this dude.

Yeah I thought I had the MSM bracket but on my inspection today it turns out I don't :(


I also wanted to look closer into my now returned weird noise. Since I stumbled upon another person with the same issue and he replaced his pinion outer bearing. But the noise comes from the pinion area for sure.
So I put the car up in the air to look at everything and went through the gears
A bit rich on decel and at 2:30 nice pop and the only exciting thing

Looked closer and after going through gears and hearing it start out it in 5th and idle to keep speed.

Has that. Still decided to leak.

Now me and the mad scientist have to rip apart the block, and replace the gaskets that never sealed.
Also clean that bitch off.

No gaskets other than OEM end seals.

I also recommend this stuff:


Of course, you may never get the pan off again

Shouldn't there be a bolt right under that water pump coolant pipe? I swear there should be a bolt there securing the oil pump if you are missing a/c. might not be your oil pan gasket, but oil leaking from that hole

If you have a/c there, there's generally a bolt there as one of the bolts holding the compressor on.

That is a very good point. How long has the compressor bracket been off the engine? You may be seeping because you are missing said bolt.

My 1.8 VVT engine with factory installed oil pump started leaking because I didn't replace that bolt when I removed the AC compressor bracket. Started out very slow but is now coating that corner of the engine quickly. Replacing that bolt is now on my to do list.

I personally like the Ultra Black series of sealant. That's what's been used.
For whatever reason something didn't seal or hot blown out when I was trying to start it for 3 weeks straight and when it finally started it leaked.

Meh, I didn't put the oil pan on.
So there's a lesson there.
I'll be happy if someone can pull anything out of my build. Helping each other is what it's about.


The bolt idea is interesting, I never noticed any oil from there though I'll check though thanks for the heads up.
One question which one are you talking about? The one facing forward on the engine?
I thought my bracket was still on there but I'm guessing that after the machine shop ranked it and what not it disappeared.

You see that round thing jutting out of the front of the engine block on the left of this picture? Its the aluminum colored thing. Yeah there should be a bolt going though it. Its like M8x1.25x85mm JIS.
