need to know what's the name of the part and if I will be able to fix it myself or bring into a shop to get it fixed.
I think it's called a bypass tubeIf you are very handy, and VERY gentle, you may be able to replace it yourself, but it's trickyWhat happens is that the plastic gets brittle from the engine heat and degrades, causing the leakMore often than not, when you go to remove that tube (and I've done a lot of them) it's going to snap or break and leave part of the tube in the intake manifoldThis means you have to use a pick tool, or very carefully, a grinder, to remove the remainsYou should plan on a good hour or two for the jobIf you DO choose to do it yourself, be very carefulThat aluminum intake manifold is not very forgiving of mistakes with a grinderI think if you have a shop do it it would be worth the extra money to see that it's done rightGood luck.
