Hello, 6 years later and your video is still useful for me 😂 Got a misfire code so i just needed to take the manifold off, gonna try replacing spark plugs coils and wires first
have a v6 st200 same engine....changed spark plug....aint simple job....nor its pretty....good work!!!!
NICE! this is the same engine I have in my Ford Contour and it needs those valve cover gaskets replaced badly! Thanks for posting this video.
no rubbing exhaust just internal squeeking.
broke down engine to timing chain found it was a bad tensioner.
keep small coffee cans to label and separate bolts and put back in reverse order.
thanks bud(old friend that died last year, always gave me little coffee cans.)
Wow, this video is inspirational. I've exact same engine on an MPV of 99 (Japan market). Also oil residue on the engine's rear. The gaskets etc need replacing. Fuel injectors need cleaning. May as well venture out now to do it myself with removing the air intake manifold. Thanks!
Awesome video. It's the same engine in the 99-02 Cougar. This willl help me alot. Much kudos ModMini👍🏼
These vans are a pain in ass my valve cover is leaking too .. it's got 165k and it's annoying me that I have to do everything this video just showed ;( lol but thank you for all the tips
Thank you for posting this video. I have a Mazda with a similar v6 that needs valve cover gaskets due to a leak into the spark plug access in the cover. Your video gave me the insight needed to tackle this project.
Super helpful. Replacing only the intake manifold gasket and plugs /wires. Thank you for the video.
***** Glad it was helpful. Thanks for watching.
***** Found oil in the rear spark plug tubes. Changing the valve cover gaskets after all.
Man man man this video is awesome, thank you, you explain step-by-step 👏 thank you
FYI, the subtitle in the beginning reads "Gen 1 MINI Cooper S Valve Cover Gasket"
Great videos!
Oops. Too late to do anything about that. :-)
Very well produced video. I was interested in how to replace the spark plugs and it appears that the air intake manifold must be removed to have access.
Yes, that seems to be the case here.
bigbird385 Hi, Replacing the spark plugs does not require removing the manifold. The front ones are easy once you use an extender tool and for the rear three spark plugs just remove the ignition coil. Watch out to make a note of the spark plug cables - which goes where - before disconnecting from the coil.
I have watched this so many times just to get my motivation lol. I love how exact and detailed you are. I need to do my valve cover gaskets but also need to replace the ingnition coil pack ASAP on my 2001 mpv exact car you are showing. I have not been able to find any correct videos. Do I have to remove everything as if I am doing the gaskets just to remove that coil pack? I really am trying to avoid disconnecting everything right now. Thank Jennifer
Sorry, I haven't worked on this car in years. But yes, uninstall until you can get to the coil packs.
if replacing just the coil pack, no need to remove intake manifold, go straight to 5:22 to remove coil pack, just use fingers to feel the bolt
Great video and very well presented. Our mpv is leaking a little oil. Where are the most common places oil leak from? Thanks for sharing.
Outstanding video very profeciona. Thank you
It's amazing how much work is required just to change the valve cover gaskets on this car. I used to own a 51 Chev pickup. Changing the valve cover gasket required removal of six bolts. End of story.
Was it a straight 6? Those are super simple even on BMW's.
Thank u so much for sharing ur information, it really helps a lot
Nice video very knowledgeable thank you so much for the info a very important question where can I get a computer for this vehicle
Great video! You made it look at easier than it is.
Good video,
But if you unbolt the overhead intake manifold, it pretty much just can be moved to one side out of the way without disconnecting everything.
Good to know. Older car and not familiar working on Mazda engines, I didn't want to risk anything cracking or breaking.
Any video. Lol! Thanks. This sounds expensive...trying to avoid $1000+ from shops
I just ran across this video, and it was super informative. I have to work on a 2000 MPV (exact same engine), and I've got to change the spark plugs. One of the things I have to do also is replace the EGR valve. Do you have any info on how to disconnect the EGR from the exhaust? Thanks in advance.
Nice video help alot
this was designed by engineers with no ideas how hard it would be to replace the spark plugs.
Good video thanks for showings us. Now there is anyway to see the head gasket remove, because water came out with my oil after overheat or is the same procedure
Alfonso montano I did not replace head gasket for this car. I think the owner has since sold the car... so I won't be able to help with additional video.
Great video, thanks
My MPV has white goo on oil cap. Saw this video and am gonna attempt to change the gaskets as you have and the water pump. Any other suggestions.
That may be a blown head gasket. Check the dipstick to see if chocolate milk is there as well.
YES DEFINITELY IS AS THE COOLANT PORTS ON GASKET ARE BLOWN INTO CYLINDER BUT IF NOT RIDING ROUGH ITS DEFINITELY SO BUT EITHER WAY NEEDS TO BE CHANGED.
Gracias
I have a 2000 Mazda Millenia with a 2.5 L V6 and 132,000 miles on it. The engine has started making a very noticeable knocking sound at idle, but it gets quieter when I speed up the engine. This makes me think it could be a worn or damaged harmonic balancer (pulley damper) rather than something inside the engine. Do you have any experience with this type of problem? Just like to get your opinion before I start taking things apart. Thanks.
New Jeffersonian I don't have experience with this engine and it could be anything, but usually knock is internal to the engine, most likely connecting rod bearings. A worn harmonic balancer would probably get worse as RPMs increase. Worn connecting rod, wrist pin or crankshaft bearings typically quiet down as engine load is increased.

I appreciate your quick reply. The reason I think (and hope) it's the harmonic balancer is because I had one wear out on a 1992 Pontiac Firebird and it made the same kind of knocking sound. I first thought it was a serious internal problem and the engine was likely ruined, but a friend told me that if it got quieter rather than louder as the engine speeded up it was probably the harmonic balancer. When I got it off the crankshaft I found the cushioning material was badly worn and split. After replacing the balancer the engine ran smooth and quiet and I drove the car another 4 years.
PS. Thanks much for making this video. Very informative.
Bannington That is a possibility and should be readily evident by removing the right front wheel and looking past the wheel liner. Good luck.
Forgive me if I missed it, but did you use a torque wrench when reinstalling the valve covers? Btw, what is your favorite rechargeable impact wrench for this kind of job?
Thx, just what I needed! 👍
How long does it take you to do this job, an experience mechanic like yourself? I believed my 2000 MPV has the same issues, it's so bad that the exhaust muffler blowing bluish smoke. But after awhile it's not blowing anymore, perhaps you can tell me why. My engine oil level is not normal either. Thanks.
I think it took around 4 hours. I've fixed a lot of cars but I've never worked on a Mazda before.
The stick appeared normal maybe a little darker considering I just changed the oil 2weeks ago. So if it is the head gasket, will he process be the same...not that mechanically inclined but follow instruction.
Head gasket is much more involved. You have to remove both intake and exhaust manifolds, coolant and camshaft sensor connections, as well as engine timing.
Thanks for the video. 👍👌
Can you please tell me the torque specs on the manifold bolts, my mpv after doing the job came back with a manifold pressure code and lean bank 1
Great video did you have to change the air intake gasket?
+charles hawkins I believe it was a basic single layer flat steel gasket and reused it.
Wow. just spent a load of $ and three days to replace plugs, PCV, plenum gasket Cat Conv and fuel inj service. Now I see why it cost so much and took so long. Al this just to pass smog in Ca.
Alan Muratet Haha. You'll probably get better fuel economy from now.
Ford Duratec 25... Same as in the Ford Contour. Find a contour SVT plenum and gain about 10HP.
+Scott Simoncic Performance minivan, woohoo! :-)
Is it necessary to remove the intake manifold if just replacing the spark plugs on this vehicle? The front facing plugs are easy to access but the rear facing plugs are a lot more difficult to reach.
no need to take out intake manifold, I don't remember if i needed to move aside the igniter box but definitely you have enough space to take out the rear plugs with an extension, getting spark plug wire puller makes job easier but not a must
Good Video.But how long was that task?
A few hours at most.
Warning! this video is 10 years old. My 2001 MPV is now 23 years old, 156K miles. FIRST check to see if you can unbolt the "Exhaust Recirculation Manifold," (shown here at 2:50 - 2:57). If you cannot remove those two steel bolts into the aluminum intake manifold (rusted solid ??)... you will never be able to remove the intake manifold and complete this job. A propane torch on the aluminum has not helped.
EDITED: 24 hours with WD-40, then an 18" braker bar with 10mm socket was successful on the frozen bolts of the Exhaust Reciruc Manifold, after 23 years.
Are the new gaskets an upgrade that eliminates the need for the sillcone bead?
+Philip Arndt Sorry, I'm not sure. Many gaskets the bead is not required but at a sharp corner like that, it's a good habit to put a small bead there just in case and to eliminate any chance of future leak from that spot.
+Mod MINI I have a 1999 mazda millennia with a 2.5 v6 dohc is this the same engine and if not would I still be able to use this as a tutorial
+Christiano niclel I don't know if it's the same engine. If it looks like the one in this video, it probably is.
hey question, i just bought a 2000 mpv and i noticed the vac tube unpluged and wasnt sure were it went to but after this vid u mention during the uninstall that it was the activation vac. if thats un hooked how bad is that for the car? as of right now the car runs fine with no issues. also, the heater lines rnt hooked up to the in/out ports on the fire wall, where would the ports be on the motor located? thanks.
+hcracer1985 Hello - I don't know what the line does but over time it will probably cause a check engine light or affect efficiency. If it was me I'd want to fix it. I've only worked on this Mazda a couple times. I'm not sure about your second question, sorry.
+Mod MINI yeah it's ok. I just bought and plan on fixing it. My other question pertaining to the heater hoses is, where on the engine block do they route to get coolant?
+hcracer1985 I already answered that above - "I'm not sure about your second question, sorry." It will probably be somewhere near the thermostat but I don't know. Just track the hoses.
what is the name of the battery tool you used it
Watch that mega fuse in that little black box..
i have a 2000 mpv and it makes a chirping spound by the alternator area but no belt or harmonic balancer on enging running...
have replaced alternator and belt ond tensioner for nothing and ideas befor i tear into timing chain area?
+Scott Tyler Exhaust rubbing on anything? My MINI Cooper makes a chirp sound when the exhaust is rubbing on something.
my valve seal is leaking oil, now i know what what to do c:
what sizes of sockets you used to remove the manifold ?
This was a friends car and 5 years ago. But since it's a Japanese car, they are probably 10mm or 12mm.

btw, to change the 3 back spark plugs do i have to take tho whole intake out?
I think you probably need to remove the intake, unfortunately.
I have the same question!
no need, enough room to do it without removing intake manifold
I HAVE DONE WITHOUT BUT TAKES A TREMENDOUS AMOUNT OF FEELING AND PRECISION TO DO SO. NOT EASY BUT CAN BE DONE.
Anyone know the name of those 2 hoses he took off at first??
do you not need taut settings when tightening up on cover
I show only the battery powered tool in the video so viewers don't get bored. I go back and snug them down with a hand socket tool.
hello, would nyone here care to help?
i have the same engine, have it top overhauled. almost done, my mechanic doesnt know where the hose from the oil filter goes to. if anyone would be kind enough to take a picture? thanks
I have the same 2001 MPV. Last year, I had to remove the throttle body (plus a lot more) and disconnect all large radiator hoses to replace the T-hose (Torture hose) I think you quickly glossed over what it takes to remove the throttle body. Too little dialog and too few close-up photos. Plus, you were completely silent upon reassembly.

anyone has any idea how much this work would cost?
You didn't torque the intake bolts?
I went back and verified tightness by hand, but I have been doing this long enough that I don't need a torque wrench for a valve cover gasket.
***** fair enough,thanks very helpful video.
where is the PCV valve located?
its right below EGR valve, at 3:17 he was removing the vacuum hose to it
12:29
I got a Mazda MPV 2000
Alfonso montano Probably same engine.
Great video and very well presented. Our mpv is leaking a little oil. Where are the most common places oil leak from? Thanks for sharing.
+Oren C Sorry, I don't know. I was fixing this car for a friend. Get the car in the air and track it down. Oil goes down and toward the rear of the car. Look up and forward and you should find the culprit.
