I searched previous posts for this but couldn’t find anything, so...

Is there any concensus on the best option to change from the original screw-in oil screen on my O-470L to a spin on filter adapter? I know there’s the Tempest adapter, the Air Wolf remote filter, and the Cessna adapter Ridiculously expensive!)...

Can I get some ideas on this from someone who’s done it and managed to not have any leaks? The Tempest adapter looks the easiest...just thread into the screen hole and tighten. I read somewhere that in at least one of the installations the screen is supposed to be left in. I think that was the Air Wolf. I also read that a while back there was an AD on the Cessna adapter regarding threads problems.

I don’t think I have any access issues. The screen is inside the large cowl door on the right side and I could probably spin a filter on or off without removing the cowling. I would still remove the cowling however for checking everything else.

Ideas?

Airwolf makes it easy to change the filter without making a big mess. Adds two oil hoses to your maintenance requirements. They need to be changed every 10 years, and are potential points of failure. The adapter that goes where the screen is now isn’t any less prone to leaks than the Tempest adaptor.

Tempest eliminates points of failure by having no hoses, but there are a few gaskets that need to be kept tight. There’s a bolt that the torque needs to be maintained on. You’ll make a mess removing the filter the first few times. Eventually you’ll come up with a system that works for you to get the filter off without spilling.

Cessna adaptor-has no advantage that makes it worth the money.

My own preference is the Tempest option.

Thanks Pinecone. All good points. I am leaning toward the Tempest. Simple, quick installation.

When installing my 520 we checked the OEM filter adapter, and the threads were failed (per AD) so it's scrap. I just installed a Tempest instead, which does not have an AD and goes on very easily. Just make sure you align the gaskets properly, bust out your handy 1" socket and torque wrench, and the whole install takes <30 minutes.

While I haven't run it yet, I'm happy with the quality and fitment so far. We'll see how it does over time.

The Tempest appears to be a reincarnation of the old F&M / El Reno filter adapter.
I had one of these on the C-145 in my old C170.
It seemed to need to have the gasket(s) changed and/or be re-torqued pretty often, to prevent leaks.
Also it was awful easy to loosen the adapter when torquing or removing the filter itself.
The Cessna adapter for the 470 (per service kit SK-210-160) looks very similar to the Tempest.

I plan on installing a filter on my C180 when I have the engine overhauled sometime in the next few years.
The Airwolf type has some advantages, but I don't like to clutter up the firewall or have any more hoses.
Someone (Marty?) mentioned in another thread that they installed an oil pump housing (?) from a different model engine (470U?)
which has an integral oil filter fitting. I recently saw an IO-550 so equipped, it's sure a clean way to go, esp if you were having the engine overhauled anyway.

One of my hangar neighbors came by a couple days ago, and noted that Tempest changed the gaskets somewhat recently because of the leakage/torque issue. Mine were different than the ones he had installed some years back. I safety wired the adapter in place and will torque seal it as well just to know if it moves, but hopefully they sorted that out. Worst case, I throw a socket on there occasionally, but I'm optimistic that won't be necessary.

Thanks guys! When I mentioned the Tempest to my mechanic the other day he said just what you guys said...” The Tempest is fine. You just have to make sure you don’t loosen the adapter when unscrewing the filter.”.

I haven’t seen one installed but with the cowling off I imagine there’s room to hold the adapter stationary with a wrench while unscrewing the filter.

It’s just a matter of being careful when you unscrew the filter off the Tempest.

Gasket replacement on the Tempest was revised for more frequent gasket replacement via their ICAW.

An oil filter will make your engine run 10 to 20 degrees higher depending on the condition of your baffling. Not really an issue for guys up north like you. But in south Texas it makes a big difference in oil temps. It's a pretty common complaint down here.

I'll bite

How does adding an oil filter make an engine run hotter?

I put an El Reno on my Ercoupe, and a Tempest on my Current C-172, it made both of them run cooler. About 10 degrees on the C-172, and at least 20 degrees on the Ercoupe.

My guess is that it was a typo and he meant to say "Cooler"

I should not have made the previous post about the oil filter adapters and high oil temps. It had no business on this thread. What I should have said instead was;
I have a box full of oil filter adapters, and at least a couple/three of them will fit an 0-470. I will look as see whats there, and take some photos, when I am out at the hangar this week.

PM'd you

After reading through the above posts again I’m wondering if the oil filter installation is going to make it more difficult to get my oil temps up now that the weather is cooling. I’ve already got tape over almost half of the oil cooler. Since I just have the green arc on the gauge I don't know my oil temps by the numbers but at the recommendation of Steve Ells I’m gonna pull the temp probe out and test it in heated water and then mark my gauge accordingly. I’ll mark 180 deg and then 212 on the gauge face so I know how the face is calibrated.

Anyone else done this?

Oil filters are worth the effort regardless of other considerations, screens are just to collect the pieces after your engine comes apart. I'd check the TCM manual regarding winter operations & perhaps suggest a lighter weight oil for the winter.

Bought the Tempest adapter and filter for my ‘58 182. Got the adapter in with no problem but couldn't get the filter canister on and it was the short one. Installation was blocked by a combination of the starter (above), the motor mount, the intake manifold and the firewall. Sent it back and will stick with the screen for now.

Wouldn’t the Airwolf adapter fit? I always considered it a slick set up. Our already had the spin-on filter adapter with a Stec starter when purchased. But I would sure like the filter on the firewall, mounted straight up and down. I have a pretty good system for changing the filter. But it only works perfectly If I can get all the planets to line up. Otherwise there is some dribbling involved.

I have an Airwolf adapter for a Cessna 185 with an IO-520 D. I know this isn't in the marketplace section, but if anyone wants it, just PM me.

I did the gauge calibration by pulling the temp probe out of the block and putting it in 180 deg water measured by a reliable kitchen probe. Used a metal cup heated on a backpack stove sitting next to the motor. My buddy put a mark on the gauge face with a Sharpie. We went to 190 deg and that was one needle width more. Seems like the one dot will be enough. I haven’t flown yet but I also went to 80W oil so that should help get the temps up where I need them. It’s the original gauge with the plain green arc and red toward the right end. It says “100 to 225 deg” on the face below the arc. At 190 the needle is straight up...about where it should be given the range.
