You mean gasping for oil? ;)

I vouch for the trap door pan from Powell......have it and run many tracks and it works like a champ.......a great investment if you are tracking the car!
And don't forget the under car rails........and the rear bar.......

glad I found this. So from what I read you do new pans instead of sending in cores due to oil contamination in the welds? could you add a oil return bung for my LSJ-t swap in the process if so then i will email gloria to order one up

for sure I have been off these boards as my hard drive crashed and i have been ipading it. not as easy to deal with forums and passwords unkess they are saved lol. Juat making a new batch of pans over xmas cheers

John, with the pans, do you want cores or not, I have I think is a new LSJ pan, wouldnt mind using it to get a baffled pan next year.

I will be getting a pan, need to find out if the gen 3 LSJ is the same or when I receive the engine send the pan up to you and have it baffled

LSJ is the largest capacity pan but has a wide sump and deep trough makes it a more difficult task to trap door ,we have to run extra baffles. The LE5 is better/easier. Between the different oil pans, here is 1.5 litres difference in capacity and the dispstick tube length and indicator is different as is the boss height in the pan for the tube. LNF and LDK are different to each other in height also

LNF and LE5 pans are the same; LDK and LNF are different. LDK is a inch deeper than LNF holds 6 litres and will not fit a KAPPA car which has a welded in cross member under the oil pan. Plus indicator tubes are different as I have said although they look identical they are not

this can lead to overfilling engine with oil if the tubes are mixed up which is a bad thing

I just make trap doors with new pans. The oil pan metal is difficult to weld also s,o we constantly look for ways to make them better

so how much for a LNF baffled pan? lol. not trying to trash a bearing in this car. the TBSS was enough lol. im going to be placing a big order from you guys soon when im about to head home so this definitely is something id like to grab esp since I plan on doing some track days this year.

Please contact Gloria@powellraceparts.com with your zip etc so she can quote shipped pricing.
As detailed we now make these from new oil pans; the contamination of the alloy with oil makes a used pan problematical. Even so, the issue is welding on what appears to be a reasonably poor grade of alloy used to make these pans. They are made variously in Israel, China and Chekoslovakia (sp) so we are currently revising how we make these things. Sometimes its needed to use epoxy on the outer surface of the pan to seal the porosity that is happening during welding. We have experimented with many different accepted welding and welding prep techniques. Recently, making a radiator for a 70's GM 4x4 resto-mod we ran into the same issue.

What that means is I shipped the last LSJ oil pan yesterday, that we have in stock, and a new trap door pan series is in " production"; all our parts are pretty much ultra low production custom made.

MY orginal GM racing trap door pan made in 2005 I still have, but its a shelf ornament, as it leaks like craZy from the welds and is a colossal pita, even with an epoxy coated base. My Powell version happily doesnt leak. Not all of them do. Its the luck of the draw. Going forward I expect folks wont have to deal with it, as we will have found a new way to make these trap door pans.

yea that makes sense with the contamination. the metal always has to be clean as possible so I cant picture it getting cleaned enough lol. but ok, I will get in touch with her. thank you.

Are these trap pans still available?

Email gloria, im sure they are.

I tried to buy one last year I believe, ended up getting a refund as GM doesn't make the LSJ pans anymore. Other pans I can't speak for but as long as you or Powell can source a new one you can still have one made.

So would this be a remedy for when I would take a corner so fast that the car wants to bog out and seem to shut down or would that be fuel pump related?

No, this is a remedy for when you take corners so fast the engine starts making rattling noises and you have to do a full rebuild. Ask me how I know :)

colodude18 do you run Powell trap door oil pan now or some other solution?

Yes, I ran his LNF trap door pan ever since my rebuild in 2013. I recently switched to his LDK pan when I got my new LDK engine.

I run his pan on my Cobalt as well. It's good to know they must to work well for you as you are probably one of the very few people that have actually done an A to B comparison.
