Don't be offended but, you might want to read thoroughly more often....

In general no, it's not enough to warn "the whole interwebz" over a broken bolt.

Now, over a bolt that goes into the engine block where the product itself is time consuming and finicky to get in there initially then yes, I thought a warning would be nice just in case someone feels the bolt not tightening up. Otherwise I suppose I could of said nothing and someone gets the same issue turning the bolt never feeling it get tight and voila; a broken end of a bolt stuck in their engine block.

You literally would have hardly if any room to get a tool in there to remove it without pulling the engine. So yes, I felt the potential for disaster justified the warning for the relevant thread concerning a product if the screws are taken from the same supplier and another bad batch comes along.

By the way, it was 2 bolts that started to give way out of the 3. 1 of them was just drastically twisted to it's last thread.

mac11 - I usually respect what you have to say, but at times it seems you're just looking for a fight. I'm sure Richard buys his bolts like everyone else, so you don't need to be his protector unless you know that he inspects and tests every bolt he ships.

Vlaze - you seem to be saying that the bolt in question was twisted multiple times without shearing - as if it was made of rubber. If that's the case, it would certainly be something I've never experienced.

It is a good idea to think about things like this, but I haven't worried about it and been totally fine. I live in Fargo, ND right now... and it gets past -20degF at times. Due to a mechanical failure on the Subaru I drove my '90 RX-7 all winter last year with the Sohn OMP adapter on it, no problems. I use Royal Purple 2-stroke oil.

Underhood temps are warm enough to thaw it out after a short time.

My solution ;)

I tapped a Greddy Catch can and I am planning on putting it up front next to MSCAI when I get it. I'll post pics when I get it installed.

That's a very interesting tank and location, corres78. I worry about the location of the output of the tank. It could introduce air under hard acceleration, but only if the tank was running real low. Shouldn't be an issue as long as it is checked and topped off periodically.

I do like the setup as I think it's more economical and less invasive. The setup I have is an exact copy of Nemesis8's. That required a new, smaller battery and some cutting of the battery tray to fit the oil tank. There is still the issue of securing the tank and battery.

Hi!

I don't think, that this will be a problem as long as the oillevel is over 1/3 (capacity of the tank is 0,9 liter / ca. 1/4 gallon). My oillevel sensor (not installed yet) will give me alarm, when the level is below 1/2 (at ca. 450 ml). ;) Max line is at ca. 0,8 liter.

Does anybody know where to get an adapter these days? Quick searching on Google didn't find anything except maybe an aviation site. The first pages of the thread said he sold through email but that was 6 years ago. Any help is appreciated!

This is the place, bought one about 5 months ago:

Awesome, thanks.

Okay guys, I am bumping this due to some new info. So, I was out beating on my RX-8 (turbo) today and while testing the temps of the intake piping and intercooler piping with my Flir, I noticed one seriously hot spot sticking out at me.

Keep in mind that this was taken at idle and not even my turbo was this hot. Everything else in the engine bay was at about 200-215F, give or take.

Except the SOHN adapter. It was almost 100F higher than everything else except the turbine housing (duh). Houstonrx8er and I were really blown away by this and it got us talking. I use Idemitsu in my SOHN reservoir and it is a Synthetic Blend. So, I looked up the MSDS fro Idemitsu and it says the flashpoint is 158F. So if the adapter is 300+F and the idemitsu in the reservoir is 130F (i measured it) then what do you think is happening to the Idemitsu when it enters the 300F SOHN adapter?

Definition of flashpoint:

The temperature at which a particular organic compound gives off sufficient vapor to ignite in air.

Basically it just means that if it hits 158* it can ignite. Flashpoint is not auto ignition, it had me confused as well.

Hmm, I always thought it was the point at which it turned to vapor.

A but weird that a part that produces no heat of its own is hotter than the source of its heat. Suspect that it's showing up hotter than normal because its a different material with different emissivity from the rest of the engine. You've got your FLIR set to e=0.85, but aluminium is down in the 0.10-12 range total emissivity, so it might be blowing out the result.

Do you have a surface temperature probe you can confirm with? I'm tempted to check myself, but car's in storage.

If not, try a couple of tricks: put a piece of black electrical tape on the adapter and see if it still reads that temperature. Or spray a bit of water on the adapter: if it's really 300+F, the water will noticeably bounce and fly off, as opposed to running down the surface.

That's a good point, never thought of that. I should try a laser thermometer.

sorry couldn't resist....

I have a an IR thermometer we can test this out with, I'll be over in an hour or so.

prepping for my SOHN install and following with interest.

would you mind doing a good pictoral of the install and posting it up??

There is already a good one available on this very site.

i searched *(of course..) but apparently my googlefu is weak.....

i shall search again..

edit..... found it... thanks.. tried a different search string...

Its fairly simply, just a pain in the ass working down there in the tight conditions.

I'm actually having a harder time figuring out how I want to feed it (reservoir and placement) than doing the actual deed.

That flash point is nothing to be worried about. The flash point of gas is something like -40F

I used a Weapon R catch can for my Oil tank. I cut the bottom off and wired in a spare low oil level sensor. Then wired it directly to my oil pan sensor. If either is low I get a factory oil light on my dash.

Then I cut off one of the nipples on it. The other goes to my actual catch can(a cheap ebay one)

I had a radiator shop put on a 1" pipe nipple on the angled side and weld the nipple closed and bottom back on.

The bottom drain opening was taped to 1/4" NPT and I ran a hose to the sohn

This is an option, I found it quite elegant. Not originally mine though. Comes from rotaryman13's thread https://www.rx8club.com/tech-garage-...nstall-241563/

You can barly see in that picture but the container on the right has a barbed nipple i believe to be 5/16 and you can drill and attach a level sensor of your liking too!
