Okay Gents - it looks like you've created an OCD Park Avenue problem solving crazy man. Before the IM problem the cruise was not working but I wasn't really going to do anything about it. I just figured that I probably wasn't going to be able to fix it myself and I didn't want to spend Dealer $$ to have it repaired. But, with my new found sense of capability and ... Read More
Glad to hear it Tracy, those engines are pretty good, and if people had guidelines to replace the UIM the same way Honda / Nissan owners's are told to replace their timing belts, there wouldn't be any problems with them. I'm glad you did not have to replace the engine for an unknown engine. I hope your UIM came with a downsized stovepipe that you put to use, and your test ... Read More
Hello All, I finished my repair on Monday after fighting with a faulty starter and convincing the salvage parts guy that even though the starter was testing okay on his test jig that it still had a problem. Everything finished up okay - check out pic link below. Got the head surfaces all cleaned up and the side gaskets laid down along with the corner gasket sealer. Let that sit overnight ... Read More
Wow. That throttle body really is clean! Good pictures guy. Hopefully when it's all back together, you'l have an engine good for another 200K miles.
Fellow BPAers, More progress today - I know I'm going slow here but I'm just trying to take my time so I don't have to repeat this process anytime soon. Removed sensors from throttle body and cleaned the heck out of it then reassembled the it. Ensured that all fluids were evacuated from the head ports and then set about doing the final cleaning on the gasket area on the head ... Read More
You do not have to cover the entire gasket surface, you just want to cover the gaps where the 4 pieces of the LIM meet. Maybe put the aluminum sides on, then a dab of RTV down in the corners, then put the short rubber end gaskets down, then another dab of RTV in the corners on top, just to make sure nothing gets past the gap. I thought of one ... Read More
The only thing I'm concerned about finishing up the repair is applying the gaskets correctly - as far as adhering them to the head/IM surfaces. Are the only areas that get some gasket sealant the two strips that sit on the block? Or do you have to follow the pattern around all of the holes (bolts and ports)? In the pics that I've seen I only see sealant on the end ... Read More
Great pics! You look like you've almost got this done. Did you look up inside the stovepipe channel of the UIM to see if it was cracking or rotted? It does look like your LIM gaskets were deformed some around the little square ports. You're LIM looks great, can I bring my next one to you? :) Yeah, now I look for cars with the 3.8L with description "blown head gaskets", ... Read More
I've tried to reuse my spark plugs the last time, but I ended up replacing them. I think it wouldn't start, but I'm not sure.. it's been a few years now. It's gonna be up to you. ;)
Okay folks - here's the latest. After a mess of labeling, unplugging, bolt loosening, and draining I've got the plenum and intake manifold removed. Once I confirmed the parts I needed I placed an order online which should have everything to me by Thursday or Friday at the latest. In the mean time I spent most of the day cleaning the intake manifold. It was pretty gunked up but the results ... Read More
Do you recommend that I change out my spark plugs? They look good to me - I think they were changed out about 4 or 5 years ago. I know I have to change my wires because I caught one of my wires and the connector head came off. Anything else I should consider changing out while I've got everything opened up?
Yep, the engine will definitely sound different without compression when your starter turns it over. Glad to hear it's turning. In the worst case of hydrolock, you may break or bend a connecting rod or piston. The heads are iron, the Lower Intake is aluminum. I wouldn't worry about changing the oil until you swap the parts. In my experience, I think all the parts (I've used Dorman) now supply the ... Read More
If you put the oil into a milk container where you can see the bottom, is there water? Even if none showing, I'd turn the engine over with plugs out for 5-10 seconds a couple of times after oil pressure is up. On mine, I'd wait to let starter cool and I'd do that several times. That will flush the oil between the bearings and crankshaft to reduce damage from coolant ... Read More
PS That "going to 130" drop in temp reading was a typo on my part - that should have read "going to 230"
imidazol97 / bowfan Okay - here's the latest on the diagnosis. Shut down A/C - disconnected neg batt - drained oil/coolant - oil did not look like it had any water in it Removed motor cover and other components to allow access to the plug wires and plugs - disconnected spark plug wires Removed spark plugs - had some minimal coolant drainage After I finally got all the plugs out I ...

I've never been clear on which years in which H-body used the metal sleeve as part of the tenioner and which used a 2nd plastic elbow to carry the heater water. Good thing is the packages usually have both tubes and 4 o-rings and you use which you need. >needle gauge in the red zone. The 3800s are somewhat resistant to overheating damage to the heads and gaskets. But I'm concerned ... Read More
That's a lot of good info I hadn't thought about. Perfect time to do the elbows. On my '98s there was only one elbow used and one O-ring that goes on the metal pipe of your belt tensioner. ( On some models there are two elbows used.) If yours only has one elbow, you take the O-ring off the elbow you don't use, and put it on the metal fitting. ( ... Read More
The big mistake was not putting coolant/water directly into the radiator when the reservoir showed low. That allowed the engine to overheat. With the relatively low miles, I'd try to resurrect the engine if the test without plugs seems okay for cranking. Drain the oil and change filter. Put in cheapest oil from Walmart and cheap filter. Just get the coolant out that's in the old oil and on the bearings, ... Read More
Here's a few pics of what you might see http://smg.beta.photobucket.com/user/bowfan/library/3800-UIM-failure
Hey TD, Not a problem. It sounds like your upper intake manifold (UIM) has done the norm. There is a little metal stove pipe that goes through the lower part of the UIM or plenum, which allows exhaust to be mixed with the air as part of your exhaust gas recirculation (EGR) system. That stove pipe comes into close contact with that plastic plenum, and the original design has a water ... Read More
Hello all, I'm new to the BPA forums but have read most of the posts from the last 10-12 years - insert way to much time on my hands jokes here. In Msg 49 a problem is described that matches my problem but I am at the very beginning of the diagnosis process. Here are my specifics: 1998 Buick Park Avenue - 83K miles - purchased used from dealer in 2000 ... Read More
imidazol97 - I believe I may have the same problem that you discussed in Msg 49 in the Buick Park Avenue forum. I have read all the msgs in the forum and would like to know if you could assist in diagnosing my 1998 BPA issue. If you are inclined to help I would be glad to hear from you. I can post here or you can msg me privately at ... Read More
I have 3.8L V6 1998 Buick Park Avenue (Non Ultra) and it has recently starting dying. At first it would die whenever I took my foot off the accelerator and just coasted with traffic. When I put my foot back on the accelerator it would just lose power and die. I would have to stop wherever I was at, put the car in park and restart it. It would restart each ... Read More
1998 Buick Park Avenue Our A/C is delivering cold air on the driver's side and hot, hot air on the passenger side. The floor fan is very hot air, too. Your help is greatly appreciated.
1998 Buick Park Avenue Driver Side Door Handle Replacement A tip broke off an arm like protrusion on the back of my door handle - supergluing did no good as I was able to easily snap it off again. A replacement handle was $93 at my dealer (ouch). I replaced it in about 2 hours, working slow and carefully - all is well now. Put window up. Remove the inner door ... Read More
I don't know about questions 1 & 2 but number 3 I know about. I have a 1997 Park and had the same problem with the driver's door. The inside of the door has to be taken apart to reach the problem. As repairs go these days, the entire latch showing outside has to be replaced and has to be painted to match your vehicle. Parts & labor $140. My Buick ... Read More
Go to your Buick dealer and ask about a service bulliten. Shake/Vibration in Steering Wheel, Floor, Seat at Highway Speeds on Smooth Roads (Diagnose/Balance Tires/Wheels) #00-03-10-007G - (10/01/2004) Models: 1998-2005 Buick Park Avenue, Park Avenue Ultra It involves replacing front control arms if needed.
The engine could not be salvaged for less than $4800 for repairs. I surely appreciate all the advice and encouragement from this forum. The mechanic even tried to find a used engine. My next step is selling to a junk yard or donating to charity. I shall miss this car. Thanks for your help.
Hopefully if it's upper intake manifold leaking it's in time to avoid damage to bearings from sitting with coolant in the oil. You didn't mention anything about coolant dripping from the motor so that eliminates waterpump for coolant loss for me. Because I've heard about bearing damage from running a motor with a leak too long in other discussions, I'd recommend having someone check about what's happening. I hope there isn't ... Read More
Come back and let us know how it works out.
Thanks for a quick response.... I will arrange to get it towed to a reliable, well recommended mechanic..... I appreciate your help.
Your car had coolant disappearing and that was warning sign to immediately find the problem. You don't say if you've had the car since it was new so we don't know if it's been repaired before. The plastic upper intake can develope leaks that allow the coolant to get into the air stream that goes into the motor. That may be the cause of the roughness which probably occurred when the ...

The check engine light had been on for some time but car ran rough occacsionally but gas mileage was fine. My buick park avenue, 1998, was draining coolant, which we replaced. after several days, I drove a 10 mile drive, waited three hours and white smoke came out the exhaust. I drove to an auto parts place and they added water to the overflow tank. the engine temp had risen to ... Read More

I was interested in buying a pre-owned 1997 or 1998 PA, until i read all the postings about this car. I'm really disappointed right now! I kind of fell in love with this car, and i'm just tried of driving 4x4's! To add on to that,i looked at all the info about the PA on the NHTSA website!(Whoa!) Still, i feel the PA(ultra)is for me.
