FEL-PRO MS 98014 T Engine Intake Manifold Gasket Set for Buick LeSabre

High quality and manufactured properly! Seems to be far superior to the GM replacement.

If you’re going to go aftermarket and purchase a O-ring seal or gasket, this is your number one leading brand I highly suggest, but don’t forget it is always better to go Oem

FOR L67 OWNERS CONFUSED ABOUT UPPER VS LOWER FUEL INJECTOR O-RING SIZES, LIKE I WAS: During this job I figured i might as well replace both the upper and lower fuel-injector o-rings on my 2001 Regal GS (with the supercharged "L67" variant of the Series II GM 3800 engine). Upon inspecting the old o-rings, i found that the uppers were exactly the same size as the lowers (as stated in a few owner's forums).I ordered this gasket kit directly from Amazon (not a third party seller) in January 2020; several reviews and customer answers seemed to suggest that it included all 12 o-rings. For my engine, this is NOT true.Besides everything else, the kit came with 1 bag of 6 black o-rings which perfectly matched all 12 of my existing uppers and lowers.But the kit also included 1 bag of 6 slightly thinner black o-rings. At first i thought these thinner 6 were compatible per some engineering revision, but the box said that only 1 set was actually for fuel injectors.A Fel-Pro customer service rep couldn't figure out what the thinner 6 were for (his system didn't even show them as being part of the kit; great job Fel-Pro records dept!); he said he's been at Fel-Pro for 18 years and he almost never sees kits include the upper o-rings since the injectors are typically left plugged into the fuel rail. He guessed that the thinner 6 were lower o-rings for a different engine variant.Via some sleuthing around the websites of other car parts retailers, I determined that (at least for me) you need to buy two packs of Fel-Pro "ES 70599" to get the remaining 6 correctly-sized o-rings.All if this is illustrated in the photos included with my review. Hopefully I saved somebody a bit of confusion, frustration, and possibly a fuel leak and engine fire.The rest of the kit is as good as I'd expect from Fel-Pro. Some bits that are definitely for other engine variants, so don't worry if you don't recognize some things.

In a world filled with cheap options, you can't cheap-out on such a critical component. This was exactly what we needed. This full kit provides you with more than you'll ever need and covers everything in the intake system. I found that the intake had been done previously, bit they used the cheap plastic gaskets instead of this. Now combine cheap parts and a shitty shop job, and you get a disaster. They had over-torqued the lower intake and popped the gaskets doing the reinstall, causing the problem to reoccur. Ain't no wonder why I got the car so cheap. But, I was able to correctly diagnose the problem before it became worse. By using the much higher quality gaskets in this kit, this engine won't see this problem again for the rest of it's service life. I recommend also doing the valve cover gaskets any time you're this deep into the engine. A few more minutes can and will save you a very big headache later. You can't put a price on good maintenance. Your car is your investment. Take care of it, and it'll take care of you in return. I also recommend fully replacing the upper intake plenum and gasket while you're in here. Also available here on Amazon. Fel-Pro once again comes through and the sellers here get you exactly what you need for a better price than your parts house and just as fast. I've included a pic of the final lower intake install using this gasket kit on my GM 3800. The one thing I do recommend doing differently than what the kit provides, is the RTV sealant. They give you the black in this kit, but we went with the red high temperature RTV. This past week, this car ran for 23hrs straight doing a 1,500mi continuous run without faulter. BUY WITH CONFIDENCE!!!

I was loosing fulid out of the radiator classic symptom everyone complains about but the radiator is not leaking. My friend had a 2001 like mine. Same thing. I found milky looking oil in my oil cap. Oil still looks like oil. Lower intake manifold gasket is letting the oil into the The coolant and vise versa, the radiator cap also had a film of darker slimy muddy oil on it. I been driving the car like this for a while. In traffic it will overheat. It blows the water into the engine oil I figured it would damage the engine if I kept driving like that. The water burns off as' steam out the exhaust , not a good thing. So I ordered the Dorman 615-180 Intake Manifold upper kit and the Felpro MS 98014 T Intake Manifold Gasket for the lower. Job was a lot easier then I thought. It took some time I didnt rush. I rented/free a torque wrench from Auto Zone. I have a 2001 Impala 3800 series 2 105K mi. Been lossing coolant for 3 years slowly but got worse. The upper wasnt real bad but the LIM gasket was horrible. You can see it shrunk brittle and old oil and coolant was nasty broken in some' places.I replaced the upper intake plenum with the Dorman 615-180 Intake Manifold it wasnt in bad shape but when your taking it all apart just replace it anyway to avoid problems. It's been 4 days now and all is well so far, parts worked well had no problems with them and the local auto stores wanted like $140 plus for the Dorman 615-180 Intake Manifold kit. Shipping was fast.It took me about 4 hours late in the day to take apart. Started cleaning to put back on. The next day 4 hours to put back on. It would have faster if I was set up but looking for tools and stuff took longer. No serious special tools were needed. Oh and I cheated I didnt take the altenator bracket off if you have help you can slide the LIM back in place slide the water inlet back in without any trouble. You should replace that plastic water elbow while apart also.I used the old one I replaced it couple of months ago but if orignal replace both plastic elbows cause they are ready to go. I also replaced the thermosat with a better quality one. As a do it yourselfer I am paying foward to maybe help someone else, I read all the reviews and watch youtube videos and they really help me. Hope this info helps! ~Lou

So far so good

These are tge only way to go when buying lower intake gaskets. Felpro has this design figured out. It has been 3 years ,and no leaks. If your looking for a great gasket...Felpro is the inky way to go. At least this set.

Liked it

I mean...my car works again. I bought the piece and my dad installed.

It does what its meant to do...

Aluminum design is how the oem should have been.
