high mileage 240 leaking pan gasket, how to avoid stripping dipstick tube?
Hey all!
I've got a 200k+ 1993 Volvo 240 wagon with the original B230F and AW70 intact. She just recently started leaking out of the trans pan, from what appears to be the rear of the pan, out of the gasket.
I daily drive this car alongside a super low mile '98 Ford Escort wagon, so I'm not exactly desperate to do the job, but I want to make sure I do it right when I change the gasket. I've read that when you remove the dipstick tubing from the pan in order to drop the pan, you can sometimes strip the tubing, and it's sometimes easier to just slap a new pan on; however, I am not able to locate an AW70 pan anywhere near me or online at a price I can afford. Is there any other safe way to remove the dipstick tubing from the pan without risking stripping it, or any other method to avoid having to remove it? I am 99.9% sure it is leaking from the pan gasket, and I was getting ready to change the trans fluid out anyway - so I figured dropping the pan to replace the gasket, then flushing the rest of the fluid out through the trans cooler lines (like I do with my other 240 and my cousin's 745) would be a good thing to do. I am super worried about stripping the bolt and having to totally replace the pan, since I love this car and I do not want to damage it in any way.
Is there anything I can do to avoid stripping the dipstick tube when I remove it from the pan to drop it? What else can I do?
What gasket is best? I currently have an iPD-sourced cork gasket to use, but I've read that a rubber one is even better. My Escort uses primarily cork gaskets, and I've never had any leaks with it, but then again, it's a Ford, not a Volvo.
I'm currently in school to become a mechanic and Motorsports engineer, but when it comes to my own cars, I guess I get even more worried...I love my Volvo and my Ford just too much.
Thanks!

You can remove the pan with the dipstick tube attached but it is a pain. You have to remove one of the mounting bolts up on the bell housing. It's a real pain to get to but can be done.
Are you sure it is the pan gasket that is leaking? It is very common for the tailshaft bearing to wear out on these cars after 200k miles causing the rear seal to leak. I have replaced a couple on 240s before. You have to replace the bearing and the seal as just replacing the seal without the bearing will cause the new seal to leak.
