Oil Pan Modifications

Topspin · 03-06-2010, 02:22 PM

I'm just getting ready to install my modified oil pan with remote filter and thought I'd post a few photos while it's still accessible. #1 is the inside of the factory pan showing the routing of the oil across the inside of the pan to the filter and then back to the main passage. #2 is the filter tubes and tray removed. #3 is a side view of our 4 wheel dr. pan with the useless tube through it. #4 is the 1/8" aluminum pieces I cut to make the new extended sump after cutting out the tube and stock filter housing. #5 is the welded up, completed new pan with about 2 qts. additional capacity.

Here's a couple more photos of the new pan-filter combo. #1 is simply a comparison of the stock filter to the new HP-1 Fram high capacity filter. #2 is the remote mounting to the opposite side of the engine. #3 shows the new inlet directly to the main passage and also the new sump area is visible. The new system will eliminate 3 very restrictive 90 degree corners and offer more filter area. Possibly a little oil cooling will be a side benefit with the system mounted outside of the pan and it's 250 degree oil.

Everything looks great!

There are better filters than the Fram, though. Unfortunately, WalMart ruined both the quality, and quality control, of Fram products, and I haven't heard otherwise. I use Wix or Mobil 1 products.

Thanks Big Blue, and I know you're right concerning the quality of the Frams, but I had it on hand and it's the proper size for the mocking up. I've got 2 or 3 around and will use them up and move on. Did you ever find your AMX? The picture below is for you - how about a 500 cu. in. all aluminum AMC complete with dry sump, belt drive cam, and fabricated tunnel ram?!

DROOL!!!!! That would be Big and Bad! I won't even ask how much. But thanks for sharing.

No AMX yet. He decided he want a Big Bad Green one, so I bought an ERTL model of eBay, and spend another $30 and 30 hours detaining it to be a 500 Special. We also bought his sisters green CRV to give him, as she has a new pink Corvette, and no job...

Still looking for a '69 BBG, not in an auction, or asking Barrett Jackson prices. As they only made 284 in this color, I think patience is the rule in finding the right car.

First class work again Topspin. It looks great.

Darn you Topspin, I didn't realized we have such a wonky setup. That's gonna give me nightmares and it's all your fault.

Seriously, nice job... that's got to be an improvement. With all the incremental improvements you've come up with, that engine has got to be more reliable.

Thanks $, you're the best!

Thanks and Sorry Bruce, I'm certainly not trying to scare anyone. It's just when I'm unable to drive the R, I try to find something to do to Her! Now I've got to get going and figure out where all the parts belong again.

Actually the part that scared me was when I looked into the pan passages leading to and from the filter. That's what the first photo shows. The second is a stock Vette pan showing the passages leading straight down into and out of their rear mounted filter. My system eliminates one of the stock passages entirely and I've opened up the other considerably for better flow.
