Part 2 Intake Removal and Installation 98 DGC 3.3L

[@PAChadClancy]

Great video. Did all this myself after watching part 1. Totally agree about taking the wiper tub out but people need to also remember to reattach the tub drain tubes. I remembered that lying in bed the night I did it. Be careful with those wiper arms. They're aluminum and I broke one trying to use a 3 jaw puller. Ended up making a tool for pulling the arms. Also, good idea to hit the rear 3 plugs and o2 sensor while top end is off.

[@JKMCANON]

Yep, intake plenum not torqued down enough. Cleared it right up. Thanks for your help!

[@andaantr]

Awesome. One thing that I'm kicking my butt on is not replacing the O2 sensor when I had everything off. So I'm going back in probably soon.

[@autoparts321]

Thanks, I was wondering how to take that wiper tray out. I couldn't find the bolts. I guess they are hidden inside. Your videos are excellent.

[@davecooper360]

Great work! Thanks for taking the time to post these 2 videos on this job. I replaced the valve cover gaskets and spark plugs and wires on my 2001 Town & Country a couple weeks ago. I removed the wiper tray assembly before starting and it was STILL pretty challenging for me. I'd never done anything like that before. I'm a total mechanic wannabe so I enjoyed every minute of the 8 or so hours it took me lol!! I can't imagine taking the whole top end out.. I don't know if I could do it.. but I'd refer to these videos of yours if I did. Thanks again!! Cheers!

[@jerrynorflet2292]

Excellent, Excellent, Excellent !! I know it takes allot of work and effort to make these videos. You have to hold the camera. perform the work and document parts. Not to mention the editing. Your videos actually give many of use the inspiration to do our own work. Thanks, I'm sure you've saved many thousands of dollars in mechanic fees.Thanks, Jerry

[@905speedgta]

good work. one thing to always remember when changing gaskets is to completely clean the surface for the new gasket. glad to hear it turned out in your favor

[@johnm.woodman1790]

Very good video, thanks!

[@JKMCANON]

Your video inspired me replace my very leaky valve cover gaskets and spark plugs on my 98 Grand Voyager. After removing the plenum I noticed two of the manifold bolts had broken necessitating the removal of the manifold and replacement of the valley gasket. It's all buttoned back up but i have a problem: it won't idle below 2500-3000 rpm. Vacuum leak? All vacuum hoses have been replaced with new as they were very brittle and kept breaking. Any help would be very much appreciated. Thanks!

[@raymondbeerenfels8089]

Thank you for the video it was a big help in taking off the intake manifold. I bought new valve cover gaskets and I want to put them in, can you tell me what to do with the thick rubber gasket that is in the cover? The gaskets I got are the blue coated metal ones, they are not as thick as the rubber one that is in the cover. Do these blue ones replace the old rubber one or do they go together?

[@autoparts321]

You were right. I did the soapy dishwater spray around the intake, connected 80psi from the air compressor into the brake booster hose to the intake manifold. There were leaks all the way around the upper plenum gasket. I pulled it off (actually only took about 30 min) because I had practice and the wiper motor housing was off still. I forgot to scrape some old gasket material from the upper half of the intake. After that runs like a charm, no vacuum leaks any more! :-)

[@Georgiehz]

i had my mechanic on my 94 cav on a problem that i do feel and still its feeding in to much gas and so i drove bout 40 miles total on half tank then had just 3 lines left or say lesser than dat i put in 7.45g of gas and filled it almost to the brim... sooo is it my gas gage playing wit me cuz i do smell some gas leakage but dont know were is coming as my van has done all tunnings. i hope u catch my drift thanks DGC!!

[@joeyboync]

I was thinking (before I got to the part where you removed the wiper tray) that it would be so much easier to remove it. I had to remove the one on my 2001 to replace an 02 sensor and it wasn't that hard to do and gives you so much more room, i went ahead and replaced the spark plugs too while I had it off.

[@PearComputingDevices]

Good job, I stumbled on this as I was looking for a head gasket video. Very detailed, and well done, especially for a first time. I love my 3.3 in my 2003 Chrysler T & C, faithful & smooth, but even an engine like this needs major work now & then. Ever do the water pump, or that metal pipe? If so your already versed like me living in snow heaven, Any time you change that pump, change that pipe too! I've changed out a few and the pressure from the new pump can weaken a weak pipe, = more $ & time!

[@chrismcdowell6877]

Thanks for the video. I have question for you. Had to take off my intake manifold to access the metal heater hoses connected to the firewall. While there I replaced spark plugs and wires. Installed new intake gasket and reinstalled everything else. Started the van and noticed that the engine would jerk a little then I would hear a pop from the muffler. Would this be a vacuum leak? Was I supposed to put anything on the gasket when installing the manifold? Any help would be great. Thanks.

[@autoparts321]

Seriously, there are vacuum lines on the back of the intake manifold? By the firewall? I don't remember seeing those. Uhmmm. I only had 2 bolts and 2 nuts on the upper plenum to lower intake. They are right in the middle left to right. I torqued them alternating from inside to outside bolts. Is there any extra bolts for the upper plenum? I noticed a couple injectors wouldn't seat very well in the lower manifold. Could that be it? I'm going to blow compressed air in and use soapy water bubbles

[@pinkonemd]

This helped me big time. You are a good teacher.

[@thayer334447]

great video! just one question what are the torque specs on the valve cover bolts ?

[@atencio1372]

Man what a great video. I was hoping u would attack the head gaskets. Just need the does and dont on how to replace them. Plus my ABS light is on. 1998 caravan 3.3L

Thanks for the info on the cowl/wiper box removal. I gotta do it to install the Dorman strut box repair cap kits!

Still helping us technical guys 12 years later. Laymans terms is best with good visual recording.

[@905speedgta]

@@Lego70001 that’s all I ever wanted my videos to do is help people. I still have so many videos never published, and in March 2024 I made a very detailed video on replacing parts on my 2021 Nissan maxima. It’s hard to edit and upload these days, I barely have enough time for my projects, but I’m looking to get back on KZbin making videos, I always loved helping people save money and showing people that no matter who you are “ work in a office, never touched tools younger,older, “everyone can repair their own stuff with the right directions

[@KZ3W]

Spot on GTA ! Great video and advice . Whoever built your van , must have built mine . That "liner" that was saggin' after you took off the wiper tray ,,,,,, mine was saggin' also ,, 😅 . ( at 12:21 and 12:29 in the video ) Guess worker was at lunch when they were adhering ( I guess glue ) this . 😅 .

[@905speedgta]

they are more towards the brake master cylinder. somethings not right here, I understand the small amount of bolts that secure the plenum, bu from what it sounds like the gasket didnt seat properly. did you just install a gasket or did you use silicone too?

[@autoparts321]

HEY, I CHANGED MY UPPER PLENUM GASKET LIKE YOU BECAUSE MY VALVE COVER GASKETS WERE BAD. Now I think I have A MASSIVE vaccum leak. When I start the van, it runs at 3000 RPM and won't slow down. Throttle is closed. I blew smoke into the intake and its coming out from under the upper plenum somewhere. DID YOUR ENGINE RUN A VERY FAST IDLE WHEN YOU HAD THE BIG VACUUM LEAK FROM THE MISSING BOLTS AND SEALS ON LOWER INTAKE? THANKS!

[@905speedgta]

@andaantr hey its no big deal.. If you decide to do the O2.. Just take the wiper tray out.. you could access it better that way

[@KZ3W]

:25 seconds to :29 seconds ,,, " Thank God " ,,,,, Best part of the video ,,,, 😂 . We ALL like when that happens .

[@905speedgta]

i havent. I had a 2003 DGC with the 3.8 same thing and the water pump went but it was covered by chrysler. I hears about those pipes. and to be honest, Id have to look and see if the 1998 model year had the pipe you speak up.. for some reason I remember a hose going right to the block..I might have it, might not..got to check on that..

[@mateymate3066]

great video very informative and right on the process, i would like to know how you removed the throttle cables from the manifold air intake throttle??

[@905speedgta]

great to hear!..stick around illhaving new caravan videos soon.. Im working on one right now

[@jamesurquhart5410]

Immensely helpful! I was looking at mine and wondering what to expect on the back side of the plenum. Now I know. Thank you.

[@cheyennedogsoldiers]

I did mine during the summer and its made a huge difference. Gas mileage went up and so did the performance. One other plus is that the cruise now works correctly. I'm assuming the vacuum leaks where killing its operation.

cheyennedogsoldiers Thats for sure. since the cruise is electric/vacuum controlled. Glad to hear it worked out. Check out myChannel and subscribe to us for new videos. ANy other questions please feel free to ask

[@alexrubio9804]

what did you use/do to clean lower intake manifold and plenum?

[@clarathames8274]

905speedgta, my fuel rail problem is the end where it makes the C. I notice you have some clamps on that end to seal leaks. Where can i find these? it's the only thing that has me down.

[@grawey77]

As I see in your second video you discovered the secret to easy service on these vans. This also applies to the 2001 through 2007 Chrysler mini vans.

[@905speedgta]

if you have missing bolts you have a problem. it sounds like you didnt tighten them in sequence. or you did and accidently skipped over a bolt ( i did this ). the bolt that was loose was the one on the left hand side by the fuel rail. tighten them all down again while its running. Dont forget about the vacuum line s on the back right side of the engine. let me know how it turned out

[@BalancedFrequencyz]

Did seafoam cause you problems??

[@ChristopherWiesmueller]

i used the video to guide me on the 3.8L engine, which is almost identical, except it is a must to take out the wiper tray, I couldn't have gotten the plenum out otherwise. Also, this is the best time to get back there and replace the rear spark plugs. The only problem with working on a van this old is the number of rusted and seized bolts, which is why I had to do this work in the first place (broke the head of a seized EGR valve bolt). I did a lot of spraying and torching to get this apart. BTW, if you happen to lose the alternator B- nut, it is a M6 1.0. Be patient on the EGR tube bolts...if it is it not coming out, keep working at it...breaking or cutting the EGR line will put you in a new kind of hell.

[@alwow77]

I had to change a heater hide behind the motor so I took off the intake and changed everything put it back together. I didn't put the wiper tray back yet and I went to start it and it's dead. Any ideas. Battery is charged and I don't know what it could be. The dashboard lights up and when I turn the key nothing. Do I need to reset anything since I took the intake off. Thanks

[@BannWorthRulz]

I have oil in my radiator, could this job solve my issue or would I have to pull the heads off as well and replace the head gaskets?

[@donaldspencer6804]

I did similar work on my 2000 Dodge Caravan, I got the parts back on just fine, my problem is I can't remember exactly where all of the vacuum lines go and I have a plug that I can't figure out where to put.

[@ChaotiX1]

Is this intake kit just an OEM rebuild, or aftermarket? Can you even BUY aftermarket rebuild kits for this engine?

[@michaelschmidt7014]

I find that, when ever I need to do work in the plenum top area of the engine, removing the wiper cowel and tray opens up a lot of room to work. In regard to the fuel rail the cross over on mine is starting to leak. Are there "O" rings in the clamps for the cross-over section? Of course Chrysler has no rebuild kit for this they are VERY happy to sell you a new Fuel Rail assembly for $144... frankly, I AM CHEAP ! I would rather spend $2 for a set of "O" rings and replace those.

[@905speedgta]

no problem. Was it a bolt towards the passenger side of the engine>?. Ive seen it twice already when Do it yourselfers do these jobs it seems the bolts on the passenger side are not tightened enough...Good luck to you and Work on your own cars from now on!..Srew paying the mechanic lol

[@905speedgta]

Im actually having a similar problem. its a fuel issue...Im in the process of figuring that out for myself. Ill let you know the results

[@samdroidva]

I have a 2000 caravan, can you come to my house and do the exact same thing? please?

[@905speedgta]

Clara, thats actually a Chrysler recall. Call a local dealer and send it in for service. recalls are Free of charge

[@JKMCANON]

Hmmm, just torqued them evenly beginning with the center bolts working outward. No kidding, saved $1200 on this job alone!

[@nataliemuzyka8113]

Which brand for the gasket set did you use? i cant seem to find the right lower intake manifold gasket, they are all too big?

[@905speedgta]

Roger Barnhart I used felpro. what year is your van? for some reason Ive worked in a auto shop and auto parts store before and there catalog systems are messed up . If you have a 2000 or a 1999 caravan voyager or town and country with the 3.3 or 3.8 try ordering the parts you need for a 1997 1998 caravan. anytime I get a 1999 or a 2000 ( especially 2000) I get parts for the next generation caravan wich is 2001 to 2007 and many things are different

[@asth8413]

905speedgta the reason why you get the same parts on the 99 to 2000 from 4 th is because they change the motor in the 3.8 and 3.3 so they had 4th generation block. The engine look pretty much the same other then horse power. So actually 3.3 had 180 hp and the 3.8 had 200hp. Chrysler lied in the engine specs. Great channel. Good video too:)

[@905speedgta]

head gaskets are easy. just follow the video, and when you get down to the heads remove all the bolts, remove all exhaust bolts carfully from ex manifold..use pri bar to pry up heads..send heads to machine shop to het checked for warping. have them deck the heads, have compression test done. buy head gasket set with new head bolts..sound like u have a dirty abs tone ring in the back wheels.. a contaminated tone ring can Give the ABS comp a False reading. Result abs light is on..let me know

[@905speedgta]

yeah, it sounds like you have a big vacuum leak. What id do is get yourself a spray bottle fill it half way with water, and add a few drops of dish detergent to it to get a soapy mix.. Spray everywhere you worked while the engine is running. theres not many vacuum lines But ive found leaks at the PCV Valve and at the intake plenum because the intake plenum wasnt properly seated and torqued down.. try that and let me know the results. Im willing to bet your problem is a loose intake bolt..

[@905speedgta]

they are replacements..scrape the old gasket clean from surfaces and install the new gasket

[@scottdc2105]

I just replaced the plenum gasket on my 1998 caravan 3.3 liter, torquing it tomorrow, any verification on the 21 ft/lbs would be appreciated since that info is all over the place on the net, thank you.

[@905speedgta]

@@scottdc2105 yes 21 foot lbs is where it’s at, as long as it’s the plenum bolts and not the intake manifold bolts. The torque specs on The manifold are way higher than 21 foot pounds . Tighten them hand tight with a ratchet don’t go crazy , then follow the torque specs. Make sure that you use a cross cross pattern when tightening them . You will be ok .

[@scottdc2105]

@@905speedgta the specs i got after asking you tells me 105 to 115 in/lbs and from haynes 10 to 12 ft/lbs. after that i planned on 115 in/lbs, where did you get your specs, i came across a wide range of specs, its hard to get a straight answer on the net.

[@scottdc2105]

@@905speedgta yes i see 21 ft/lbs on the tighttorque websight but the majority values are in inch lbs such as 84 to 105 in/lbs, considering the threads are into aluminum much softer than cast iron i want to be very careful , i know there are two steel studs and only 2 bolts into aluminum they must be of uniform torque.21 ft/lbs is 252 in/lbs, twice of the average ive seen.

They go rid if the 3.3 and the 3.8 because the pushrod engines were to easy to work on, I know some one that has a 3.3l carivan with 275000 miles on it no leaks still runs good

[@arome-md4vf]

Those both motors can go easily 350k miles before they die. I personally dont like the new chrysler 3.6 liter vvt motors. I but you're right the 3.3 and 3.8 were pretty solid.
