while checking my canton 242t for leaks I noticed that if I set it on a flat surface the pan rails are not flat.. in some places there is a 1/16-1/8 of an inch of a gap.

Will the pan rails flatten out when the pan is fully bolted down and torqued with the support rails in place? The engine is getting assembled and I don't want to have to crawl under the car to replace this thing..

thanks..

Between the thick oil pan gasket as well as the pan support links that go between the pan and the bolts which run the length of the pan I wouldn't worry about it.

Thanks, I thought it would probably even out, but with so much time and money invested I wanted a second or third opinion on this thing..

Well, for a third opinion, I would think a 1/8 gap could be a leaker for sure, depending on where and how the pan is deformed. What does the pan look like? If both rails are straight and flat but not parallel, maybe the pan will twist into shape when installed, but if they are dneted or wavy I would try to straighten them. I HATE oil leaks. I've used a hard flat surface (5/8 steel welding table in my case) under the pan and a tool & hammer (chunk of 3/8 plate or similar, be creative) to tap down high spots on a pan between bolts, and bolt holes that are pulled in from overtorquing. Just be careful not to make any wrinkles or creases. Long gentle gaps are preferable to smaller, but localized, gaps.

not trying to hijack your thread, but will the canton pan work with studded two bolt mains with out any clearance issues. I am going to stick it under my engine while the motor is in the car if things will clear for me. Thanks Art

Thanks for another opinion, the gaps are long in the middle in one side, maxing out at about a 1/16th, and in the rear on the other, a long gap but runs almost to an 1/8th.. I will tap the thing into shape..

On the other side, hijack away, I am putting the pan on a two bolt studded main today so I will anwer that question later.

Well, found out that the canton pickup I have does not work.. It is for the standard volume 3/4 inch pump.. the pump I have is a 10% over HV melling high performance unit.. Not sure if there is a big difference between pickups but the standard one certainly didn't fit.. ordered up the HV pickup and will see what happens..

SS RRR

Is that what Canton recommended? If not, it'd be a good idea to talk to Canton to see what p/u they require for the pump you have.

The pickup I tried is what came with the pan, 20-013, in addition to being the standard volume unit, there was NO way it was going to fit.. the pan was almost a 1/2 inch off the back of the block with that pickup in there.. I ordered up the 20-023 for melling HV units, I will give them a call and confirm that is the correct pickup.. if the height of both pumps is the same, the pickup I tried in addition to being for standard volume pumps was welded incorrectly, it was angled when pressed in and bolted up..

I'm running the same pan, with ARP studs on the stock main caps.

Thanks for the INFO!!!!! do you run the stock windage tray with this pan also or is the pan equipped with some better oil control parts

J's 82

no, no stock windage tray, it has all you need built in..

It cleared the studs, but I didn't rotate the assy. so didn't want to sign off on that just yet, glad someone else chimed in.. I had to clearance it to clear my billet oil filter but apart from the pickup issue it would of gone on yesterday..

Well the official verdict is that the 20-023 oil pump pickup is shorter than the 20-013 pickup..

the one I had was advertised as fitting the hv units but it turned out to be the 20-013 for standard melling pumps... to fit the 10% over melling pump the 20-023 is needed and now it is on all fits just fine.

as for the rails, well straightened as best I could, I was not happy with that aspect of the pan. We'll see if it leaks.

cleared the 2bolt studded mains no problem..

Lessons learned..

my Canton leaks in the pass rear corner at the rear main seal.
Nice pan design regarding oil control - crappy fitment.

The pan works better with the cork SBC gaskets rather than the silicone factory ones with the spacers in them..
