Hi guys. I think it's just down to "stiction" attributable to the parts concerned not having been separated for 13 or more years but I don't want to apply too much force in case I am missing something. I need to replace the intake manifold seals on my 2000 X1 and have followed the advice given in sections 4-105 and 4-106 of my 1999 and 2000 model years service manual and removed the air filter assembly, disconnected the throttle cables and the rail and 2 screws that hold the air intake and throttle body to the under-side of the intake manifold along with the TPS electrical connector and there would now appear to be nothing holding these components together but they don't want to come apart and I can't get to the two allen screws on the gear case side of the intake flanges with the throttle body in situ. Any tips or suggestions would be gratefully received. Richard } | ||

Stiction I believe it is. When I did mine, I had the same issue, and worked around it. Of course, lazy person that I am, I didn't disconnect or remove much of anything. Don't remember exactly what I did, but it was decidedly 'fiddly', and involved a goodly selection of allen wrenches. Thank goodness the the gearside screws only need to be loosened a bit, not removed. Once you get a turn or less, the manifold clamps will slide out to the primary side. One caution: If you do get the throttle body out of the manifold, make sure you have a throttle body seal (p/n 29539-99Y for an '01 X-1)on the bench beforehand. Hope this helps, Dave | ||

Thanks Dave. I had planned on re-using the throttle body to intake manifold seal but I take it you wouldn't recommend it? Richard }  } | ||

I would not use the old one over. In addition to its age, it has been through many heat cycles, and is most likely very brittle and stiff. Has probably 'glued' itself to the throttle body (hence the difficulty in getting the throttle body separated) and will tear when coming apart. Hope this helps, Dave | ||

Don't reuse the seal. Period. Replace all 3 of them. Make sure to use SylGlide on all of the seals.. | ||

Thanks guys, I'll order the throttle body to intake manifold seal now. I'm in the UK and am not familiar with Syl-glide. If this is just a US brand of basic silicon grease, I can get some in the UK. Would copper grease be a suitable alternative? Richard | ||

As a pig of a job goes this one would give Arnold of Green Acres a run for his money and I assume that experienced HD / Buell spanner men use ball ended Allen wrenches of various lengths and have finger joints even more pliable than ET? Anyhow, I finally managed to overcome the stiction between the inlet manifold and the seal holding it to the throttle body by applying several sharp taps with a light hammer to a 1/2" or so diameter aluminium bar introduced between the cylinders from the primary chaincase side and pressed up again the base of a convenient tab on the underside of the throttle body as per the attached photo. Said seal, along with the 2 intake seals all appeared to be in good condition ( still pliable and with no cracks or splits or signs of leakage ) but, on the advice of two good folk on here who know better than me, have now been replaced with the help of a smear of silicon grease. Thanks again for your help guys. Richard  } |
