3800 Intake leak

Well I've filled my radiator reservoir tank on my 98 bonnie a month or more ago and after checking it every now and then I've noticed a drop in its level. Sso today I decided now would be a good time to pull of my throttle body to take a look at that EGR pipe and wouldnt ya know it, the intakes leaking... Its not as bad as some but its enough of a leak to keep me from driving it any longer. I'm gonna see about either getting a refurbished upper and lower intake to make replacing mine go a lot quicker or fix the ones I have. During this I'll snap pic's of the process and load them up on a webpage. I got a manual and all but if any of you done this before want to give me any tips on this job let me know.

Sorry, I can't give any tips. I'd be interested in viewing pics though. I've been trying to understand this whole deal with the EGR pipe & the upper intake manifold. My 97 SE had two upper intake gaskets replaced over the course of 110,000 miles. Good luck anyway with the job.

Well I got the Upper intake off right now. Anyone know what the O.D. and I.D. is for the new egr pipes?

Take a look at here

is from a intake I got off of someone. Pic link 6 should be a lower case "I" in the name "image".

There was an issue until '98 or '99 that was related to a too wide EGR pipe that degraded the plastic of the upper intake manifold around it due to heat. That was addressed in a TSB and fixed in production cars.

However, there's something else or maybe the same that's causing leaks, though usually not as catastrophic as previously. I was unfortunate enough to get it on my '02 Bonnie at 17000mls... I don't have to say that at 25000mls I'm eager to schedule a visit to the dealer for this recall. ;-)

Well I got my car back together today. I'll upload the pics of what I done to a webpage later on. Right now I need to get out and drive and see if the systems truly going to stay sealed or not. The dang gaskets cost me a 100 bucks... If i had preordered them from somewhere I could of got them for less.
