There should be a gasket between the flange and the turbo. I am doubtful that any permatex hold up to the temps that the turbo gets to.

 

The CHRA doesn't get anywhere close to as hot as the turbine housing does.

Just checked the FM install directions looks like they recommend "smearing sealant" on the gasket and fitting before install. So I'm guessing A there is none there or B in the disassemble/reassemble process the seal was ruined.

They Do recommend a Gasket part number 02-70510. I'm wondering if I can get that locally or if I have to get it from them. I'd really like to be doing break in this weekend!!

Called Flying Miata- I love that company they are so great and so patient. They gave me a Mazda part number. Ordered the gasket from the local Mazda dealer they said hopefully they get it tomorrow morning! FM also said I could use the permatex only as a short term solution. When I get the paper gasket to coat both sides with permatex And it should be good to go!


The smoke in the exhaust seems to happen about the same time as the oil leak from the return line so the two may be related, but then again I'm certain the rings aren't seated properly yet, and being as the car has only been to 180 once I'm guessing the smoke may be related to that also. I guess I'll know for sure when the gasket gets installed.

 

I don't understand why Mazda would have a garret turbo drain gasket.

 

They don't. I called flying Miata and told them I needed the gasket asap they checked napa, autozone etc and they said the fastest way to get it would be to use the gasket for a msm oil pick up. And that I should be able to get it at the dealer faster than they could get it to me.

Did i I mention how awesome flying Miata is?

 

Just to confirm the oil return line can just be removed and reconnected since there's no oil in it when the car is off correct? I don't need to drain the oil to install the gasket do I?

 

If you drilled the pan in the correct location then the drain port is above the level of the oil in the sump, so yes, you can pull the drain hose off without worrying about it peeing oil on the floor.

Got the new gasket in today, coated both sides with permatex as reccomended by FM. Fired it up and it appears to be all good. Unfortunately my tuning laptop took a poop, so no break in today. I also noticed a possible leak from the heater core. I'll see if a new worm type clamp does the trick.

 

The heater core pipes are really easy to deform. Get a pipe swaging tool like this to get them back to round:

HDX Swaging Tool HDX053 at The Home Depot - Mobile

 

I got one and used it before dropping the motor in, unfortunately the deformation was maybe 2 inches back and the flare section on the tool couldn't reach back far enough to fix it 100%. I got about 80% fixed, if the problem persists with the new clamp I'll pull the hose and add some sealant.

 

An Oiteker clamp works really good for shitty hose connections. Mcmastercarr calls them "full circle clamps " I think. You need a 5 dollar set of pliers for them too. You will never use worm clamps on anything ever again.

 

I used verious sized sockets to get the heater core pipes back to round. Also, spring clamps, like the stock ones, are great. Use those.

 

Damn those are nice! How do they compare to t bolts? There's a place local that sells t bolts of all sizes but their hours aren't ideal. I hate worm gears, but right now it's what I got, plan to upgrade once it's all running. The t bolts and worm, gears I like that they can be installed without removing the hose.

 

Fired up the car, still smoking and leaking oil once the car gets over 160. Removed the return and feed lines to check for obstruction, nothing obvious. It looks like the oil feed hose may be leaking at the fitting, and there does not appear to be a restrictor in the line so maybe that's the problem? Too much oil pressure?

The turbo is a Garett 2560. I pulled the oil feed line and it does not appear to have any restriction. I'm not sure yet how to tell if the turbo has a restrictor in it or not yet, but if it does not I'm thinking this may be caused by oil blow by. According to Garett the turbo should see 40-45psi at max rpm, but I'm getting 60psi at start up tapering to 40 at idle. It could be a hot side seal, but if the seal is shot I feel like there should be some shaft play. The shaft is solid, no wiggle no nada.

 

find a 1/8" pop rivet, pull out the shaft, unscrew oil feed, put the rivet collar on your oil inlet fitting, reattach oil feed. stop posting.
