Kudos for the Video! Sorry for chiming in, I would appreciate your initial thoughts. Have you heard about - Trentvorty Safe Vehicle Theorem (do a google search)? It is a good exclusive guide for discovering how to repair your car the simple way without the normal expense. Ive heard some great things about it and my friend after a lifetime of fighting got excellent success with it.

I want to thank you guys. I had a friend come over that is more mechanically inclined and this helped us step-by-step to perform this operation. I really appreciate also sharing the torque recommendations and how to do it. I found out the last person who did this had really loose bolts on this area. Now I know that it will be put in correctly. :-) I also appreciate your meticulous explanations on what to do next. It was exceptionally helpful! Two thumbs up on your video!

Im mid process on this right now. I purchased just the gasket. Clearly you recommend replacing it all but should I really worry about it? Also; what indicates that the lower is bad? There's so much coolant and oil all over my block it's truly hard to tell what's what.
@kainhall
@kainhall 3 года назад
coolant all over the block and in the oil = lower intake gasket is bad...... you answered your own question. . and yes.... spend the extra 20 bucks and replace all the gaskets.... coolant elbow O rings, injector O rings, thermostat gaskets . the upper intake gasket CAN be resued if its still soft and isnt messed up but its like 10 bucks for a new one....... and peace of mind is worth millions
@stephenh5944
@stephenh5944 3 года назад
Did this yesterday and today. It took a bit longer than 17 minutes. Just take your time and go slow, it's not that bad. The most difficult parts are removing and reinstalling the fuel rails, and getting that bendable bracket to line up. For some reason the bracket has an on-size screw hole, when it could have been made oversize. You might want to drill it out a bit and paint the bare metal right after removing the throttle body to make attaching it to the throttle body easier.

I replaced the spark plug, wire and coil but it continues. I did a pressure test on a few cylinder and the number 1 cylinder has only 75 psi, could the upper intake cause a loss in pressure

Thank you for the video but I’m wondering how to decide if it’s the intake or the head gasket. My daughter’s park avenue is definitely leaking from either the intake or the head. The coolant in the radiator is sludge but the engine oil is good. I am leaning towards the head gasket what is your opinion?

I did this repair on my 97 lesabre also including lower gasket and probably watched this video a year ago before I attempted the repair. Immediately after putting it back together I got a throttle position sensor fault code. Replaced it hoping it had just went bad but code still exists. Now I'm getting a map sensor fault. Maybe 2 hours of running since repair. Any idea what the problem is? I suspect the Dorman intake plenum insert was not up to par. I was aware it didn't fit as snug as I'd have liked before installing but thought it would be efficient. Not in not so sure. Would that cause my engine fault codes?

I don't get the difference between the upper and lower intake. I have a buick 2000 lesabre. My mechanic said I need a whole new intake. And I noticed I'm going through a lot of coolant. don't see any other problems. Is the upper intake only related to losing coolant?
@1AAuto
@1AAuto 7 лет назад
+SirTalksALot01 Well, intake manifolds are often associated with the loss of coolant. It's likely the gaskets which are shot, but it's possible that the manifold itself needs replacing. You could do a little research on intake manifolds and coolant leaks, or maybe just ask your mechanic for clarification. It's hard to say what your problem is without actually being able to see it.

A little late but incase anyone else sees this and needs to know the straw looking thing goes into a hole on the left side(passenger side) of the upper intake plenum. It goes into the part of the intake where the pcv is housed. I have no idea why they dont come installed into that hole when you buy the intake but just remove the gasket face the straw looking tube up into the hole and stab it in while reinstalling the gasket onto the intake.

My upper plenum was aluminum or like a cast iron, not sure, but it was not plastic. For some reason I can not find the right gasket for the plenum.....have any idea where I can find a gasket for it. So far I have gotten the wrong gaskets, that are ok for any thing 95 and up but not 94 and under to 92.......Help.!!!.........Bobby

+semaarairsoft123 Unfortunately, we don't have a video on replacing the head gasket for this vehicle. That's a particularly large job on most vehicles though, so if you're a beginner in auto-mechanics, or you don't have a well experienced mechanic friend to help you along, you might reconsider trying to do it yourself. We typically won't discourage people from doing their own work, but it's important that you know the scope of any job before starting on it. This is a pretty good article to read through to give you a little info regarding blown head gaskets on these motors.
