I have had a small coolant leak for the past month but just yesterday it seems like its way bigger now and I want this fixed ASAP! The leak seems to be coming from the lower intake manifold and possibly the throttle body but im not entirely sure. Is it possible for me to fix this myself if I have no experience disassembling engine components? Im thinking its just a gasket or something but I have no idea because I havent spent a whole lot of time checking it out.

A lower intake manifold is something you'd probably want someone with a little experience to help you with. I just did mine over the weekend and I posted a couple pics, you can see that thread here: http://www.bonnevilleclub.com/forum/...ic.php?t=25292. Within that thread there'* a link to another thread that details the procedure even more. With your experience level you will absolutely need a Chiltons, and like I said you'll want another person there who knows engines moderately well. I was pretty timid about digging into mine, but my buddy from the TCCOA was a HUGE help for helping me get past my apprehension. If you're nervous about doing your own spark plugs, you'll definitely want some help/supervision. Doing the job yourself will save a ton of money, but keep in mind that if you've got coolant leaking into the engine right now then your motor is already being damaged. If you know it'* coolant getting into your crankcase, get your oil drained yesterday (yes, I meant to say yesterday). From what I understand if coolant is getting on your main bearings kiss that motor goodbye. Whatever you decide to do, do it pretty quick. Either way, at least pull your dipstick and check for milky white stuff (coolant) in the oil. If its there, drain it ASAP.

Just changed the oil myself last week and I didnt see any milky stuff whatsoever but since this problem got worse just yesterday I think I would do best to check it again. The coolant seems to just spray out all over the transmission from under the throttle body but I cant really see under it so it may be coming from the manifold. I most likely wont be doing this alone so I guess I'll just have to find some way to dish out the big bucks. If by some miracle I could do this would I need like an engine rebuild gasket kit or something?

Get a mirror. If it'* coming from between the TB and the UIM, It'* probably an $8 gasket to fix. If it'* coming from between the UIM and LIM it'* a $4 tube of Gasket maker.

Hmmm... if you say it'* spraying out all over the transmission then you really should get a good look at where exactly it'* coming from. See if you can clean up the coolant that'* already spilled on the tranny and then have someone run the car and look to see if you can see it dripping or running out anywhere. And yeah, check that oil again. Hopefully a gearhead will pop in here and verify what steps you chould take. I know for sure if you do the upper and lower intakes you'll need gaskets for both, and a new TB gasket if you remove it.

I solved this same problem not a month ago on my own car. Find out where it'* leaking.

Sorry, took way long to post there... Dame, if it'* coming from between the LIM and UIM, shouldn't he go ahead and replace the gasket? If the gasket is torn and continues to degrade it could potentially leak internally, could it not?

There is no real gasket there, Just Loc-Tite gasket maker from the factory. If it leaks to the outside, It'* only another couple inches to leaking internally.

I'm confused. So what was the thing I just put in between my LIM and UIM over the weekend? I know it'* kind-of a hard plastic deal, but isn't it potentially catastrophic if coolant gets from the water ports into the internals? If the gasket is starting to fail externally isn't it just a matter of time before it works its way to the internals? Relieve my confusion please!

Ummm..... You have an L36? And yup, it'* just a matter of time.
