Hey all,
Does anyone have a use cast pan, Clarks, Otto or Offy that they would sell? I'm prepping to pull the engine out of my '68 and want to reseal it while its out. I thought a cast pan would be nice while I'm replacing the gasket and have it off.

Also, any big benefits to one brand over the others?

Thanks,
Dave

Since there doesn't seem to be any used ones available, next questions are...

1. Which of the available new ones is better for cooling (Clarks or Otto)?
2. Is there a big benefit to the added spacer to increase capacity? Does this cause any issues (ground clearance, leaks, etc)?

Thanks!

Dave

A guy in Phoenix has two of them for sale on Craigslist. I have purchased several parts from him for my '65 Corsa 140 & he is great to deal with.I met him at the Toss several years ago.

Otto



Polished Offenhauser

The Clarks pan has more fin area than the Otto pan, but in the real world, any difference in oil cooling between these 2 pans would be so slight as to be difficult to measure. Adding capacity is a debatable advantage, as it just takes longer for the oil to get up to temperature, and adding capacity by lowering the oil pan increases the chance of something hitting the bottom of the pan and possibly causing a leak. There's a sizeable, noticeable ground clearance advantage to the Otto pan vs the Clarks pan. Both are really good pans, but the Otto is lighter and has more ground clearance, which may or may not be a big deal.

I have several deep aluminum pans for sale. Let me take some photos and post later tonight.

I think the biggest advantage to aluminum cast pans is
better seal to gasket due to obvious stiffness of the
castings. Many stock pans seem to resist any efforts
to straighten.

Down side is occasionally I hear of new cast pans not
being flat which makes holding gasket tight difficult.
Check flat/straight with straightedge before using.

Go with the Otto pan for the ground clearance.
If you want a deep pan I have a dirty one for $100.

I thought I had two but remembered I sold the second one a couple of weeks ago.

This one is verified flat on the gasket surface and it's clean but the outside needs a little love. As is typical, fins at the rear edge are rugged. I would smooth them up if I were going to run it. They could also be repaired with a bit of TIG welding work.

I'm thinking $80.

We have a long steep gravel driveway, and over the years our Otto pan with angled fins has caught and broken off fins. I think a pan with fins running front to back would of faired better

Thank you!

I was in Palm Springs this weekend and don't remember seeing any aluminum oil pans for sale. I did see some valve covers but not pans.

No one is going to exclaim regarding the ask for the Otto pan and valve covers for sale in Phoenix?

$1000 is a big lot of cabbage!

Yes the new Otto pans from Clark's are not flat. Someone on here warned me.
When I got the pan it was not flat and I called Clark's. They said they'd send out another the day I called. Great service, BUT THE NEW PAN WAS NOT FLAT. Two places that were 0.040" off, basically the replacement pan was warped in the same place as the first pan!!!!! I told Clark's about this and was told the pan would bend when bolted down - NOT 0.040"!!!!

Clark's should send the Otto pans to a machine shop and get them cut to be straight and flat!!!

I did like the Otto pan because it isn't as deep. I need the clearance going up my driveway. So I kept it and fixed it myself - grrrrrr.

Wow! I've only ever seen one other Otto Parts magnesium pan. I almost bought it, but couldn't pull the trigger on the expense.
