for some reason i can not, put in new intake seals on my 99 x1 with out them leaking, if anyone can give me some tips or pics or what ever, i know thats where my problem is i just cant fix it. | ||

Before tightening, I reach into the intake manifold with a finger and feel to make sure the manifold is aligned with the head. Adjust as necessary to get both sides aligned with the heads, then snug up all four bolts. Use the same technique to make sure all is still aligned then tighten the bolts. ymmv.. :-) | ||

Lubricate the new rubber seals with something like Sil-Glyde (Look at an auto parts store). A tube will last for years and has many other uses. | ||

Based on everything I have read about this topic, it looks like the main source of leaks after seal replacement is the alignment of all the pieces that go together. Now like I mentioned in your other thread, the FSM refers to an "upgraded" molded plastic seal/flange assembly used in the post-2001 X1s thus acknowledging the alignment issues with the old design. May be it is just a fiction since no one seems to make any references to this new part. Everyone is using the "old" separate seal and flange assembly. May be someone with a Parts Manual for a 2001-2002 X1 can confirm this myth. | ||

ive done all the things mentioned. anyone here in SO.CAL that might want to help me out? | ||

Damn, 4th attemp, i took my time making sure everything nice and even, everything alined. and STILL not right. S.O.B is still F-ing leaking, it seems so easy, but im just not getting it. | ||

Do you have the flanges correct, the front to the front the rear to the rear? The bolt hole/slots in the flanges/heads are not opposed 180 degrees, could be the flanges reversed, which would offset the port opening. Don't know if its possible, just a thought. I've replaced dozens of sets over the years and never had a problem. | ||

Also make sure all your mating surfaces are clean and smooth, not grooved or scratched. That includes the head surface, the flange-to-head surface, and most importantly the flange-to-seal and seal-to-intake surfaces. If you have a nick, or a piece of old seal stuck to 'em...you're screwed. Old toothbrushes and brake (or carb) cleaner, followed by a wipe with a clean rag. | ||

flanges are in theyre right spot and everything what super clean. | ||

Edgar a suggestion put it all together loose including the throttle body / carb then start from the outside and work in, or in and work out unless some thing is drasticaly wrong it should work, I have not needed any lube for any thing except injector orings. I would examine all parts and be double sure that parts are in good condition and in the correct orientation. I have done the intake tract 3 times now its fiddly but not difficult. | ||

I don't know if this is possible or not but you could try pointing the carb cleaner spray hose (or propane nozzle) to either between the flange and the head or right at the gap between the intake manifold and the flange and see if you could further pin point the source of the leak. The manifold should have a fairly tight fit inside the flange. The seal should also stick out a bit once it is seated inside the flange. May be you have seals and/or flanges which are out of tolerance. |
