    I am in the process of replacing the shift shaft seals on my 328. Or at least headed in that general direction.... Like so many others before me I have discovered that the dipstick tube/dipstick tube extension needs to be removed. This is probably a 10 on the PITA Scale of 1 to 5.

    I have loosened/uncoupled the 27mm (1-1/16") nut and removed the dipstick tube. I am now working on removing the tube extension. Here's the rub....Based upon the posts from others I think I should be able to remove the extension tube out with my fingers or with wire, with out removing the 24 mm fitting that screws into the block. That's just not happening. Any suggestions?

    I have tried to remove the 24mm fitting and it's seized. (Even after soaking it with PB Blaster for two days.) Assuming that this is the only route left, is it safe to use a small propane or butane torch on this fitting? Any thoughts will be appreciated. Thanks

    Have you tried to use a sharp pick to pry it out? I used small craftman pick and was able to get it out easily. As for the 24mm fitting, I was able to to fit a 6-point socket on it and use a 1/2" rachet to remove it, I remembered you can get add pipe at the end of the rachet driver for additional leverage. I would make sure to use a 6-point socket. Mine came out relatively easiy. It's really tight in there and having a small head rachet and a thin wall socket really help.

    Hi Ken-

    I haven't tried a sharp pick yet, however I have tried using a long screw driver as a means to see if the tube extension will at least wiggle. That effort failed. Did you use your pick as a lever in attempt to get the inner tube to wiggle around in the seat of the fitting?

    As for the 24mm fitting; I am using a craftsman 24 mm deepwell socket and a flex head ratchet. I had an old piece of metal conduit (about 10 inches long) that I have fashioned into a cheater bar. No luck with this configuration. I am now to the point of considering the use of a propane torch to heat the fitting.

    Getting back to your original point; I'll try inserting a punch into the tube extender. The larger diameter shank should give me more surface contact on the inner surface of the tube. Maybe this will be an improvement over the screwdriver. I'll let you know.

    I've had good luck with "frozen" fittings by drenching them with penetrating oil and letting them sit for a while, then repeat.

    In a pinch, 3-in-1 often works, too. This works far better than spraying with WD40.

    Use Kroil if you have them, my guess the someone may have used lockite on that fitting. If you are going to heat it up, it's real tight in there so it might be hard to get the flame in there. Make sure you have no fuel leak or bad hoses around, plan and clear your escape route, fire extinguishers near by...

    Yeah, dipstick removal is a PITA fer shure!!!

    I've had a couple of tubes that were bent or kinked. Luckily I was able to fish them out with a hook made from a piece of coathanger.

    Before I used a torch, I'd try heating the block in that area with a commercial grade hot air gun. You really really don't want flames in that area unless there's no other alternative.

    I had some time to think about the matter and came up with the following. The eye-bolt Should probably be 1/4 x 6". The washer(s) should be at least a 1 inch OD and the wire 16 gage or clothes hanger wire (14 gage?) I'll let you know how this turns out. If all else fails I'll try Kroil and let it sit for a day or two
