4G63 Head Removal Process - 1G Talon TSI

Basic overview and step by step process of removing the head from a 4G63 motor. Some steps may differ depending on your car but hopefully this video is helpful.

Just completed this job on my eclipse. I’m a KZbin mechanic and it took me 4.5 hours. I was super detailed and labeled bolts and took a lot of pictures. Legit saved me $1400 would of been $1600 but took my head to the machine shop

[@rocquechatel149]

I was in the middle of doing mine when I got stumped, thank god there are smart people like you out there

[@lemonke8882]

This video may not have many views, but the views it does have are people who insanely appreciate this video.

[@WilliamDye-willdye]

Thank you very much for this detailed, careful, step-by-step video. It's a big help to the DSM community. Hopefully I won't have to take off the head on my Eclipse anytime soon, but it's only a matter of time. Thanks again.

[@sand0077]

Very clear and concise description of the procedure. With luck I hope to tackle this job on my wife's 91 eclipse but with the 1.8 liter engine. I'm presuming it will be less involved since it's a single cam. Fingers crossed!

[@ian376]

Excellent tutorial. Easy to understand and the pacing was very good. Its been a lil while since I had to do a 4g63 head and this was the refresher I was looking for. Thank you!

[@clutch-slayer]

Ian Kotowich thanks for the kind words!

[@atuaredeye]

Josh yes its a good video but how do you put the cam gears back on with the belt still attached?

[@lukegibson1000]

Josh you need the tensionor tool

[@recheveste31]

the last 5 seconds of the video killed me

[@pueblodsmrs5624]

thank im removing mine too to change the valve cover mine has a crack video came in handy keep up the good vidz dsm4life

[@XuniqueLyEm0x]

very nice information just bought 1996 talon si now i can get an idea how to remove the head

[@user-sf9fz1ep5o]

Hey man, love the video, question though. Is it necessary to remove cams to remove the head? Timing belt snapped this morning and I may have to/want to remove head and check valves and pistons.

[@7giop13]

quick question , how did you get your cold air intake? I've been looking for one to install on my naturally aspirated 93 eclipse and i cant seem to find one for it, wanted to know if you did any modifications for it to work? what did you do with your MAF sensors?

[@aguia473]

Good friend I have a Mitsubishi 1.600 gti 16v 4g61 engine is more or less the same, I don't know the torque of the screws can you tell me if you know?

[@Daddimirr]

Threw a jackstand on the edge of the pan and gently removed my driver motor mount to get the head off instead of the stud

[@brainscan83]

Hello Did you use MD998738 tool?

[@nathancruz2843]

When reinstalling cam gears, will they stay the correct tension with the zip-tie method?

[@clutch-slayer]

+Nate Cruz I don't have a definite answer for you... I have never had an issue with doing it this way, and I've done it numerous times. The 'proper'/service manual way to do it would be to use the MD998738 tool that compresses the tensioner. From what I have seen the zip tie method I use in the video doesn't affect the belt tension significantly.

[@davidaguayo3785]

How are you have a plymouth laser and am looking for the water pump inlet pipe do you know were I can find it

[@cypherhill9852]

Just a question but does the battery have to be disconnected at all during this process ?

[@clutch-slayer]

Not a bad idea in case you short something out

[@Blah4551]

so if the 2 cam dowel pins are @ 12 o clock....What if the timing marks on the teeth not even with each other?.....

[@clutch-slayer]

+Brad Hernandez Hey brad, I think you bought some parts from me off of DSM classifieds lol, your name looks familiar. If the 2 dowel pins are both pointing straight up and the teeth aren't exactly lined up it isn't the end of the world. I believe if you head or block has been decked, the lines will not be perfectly lined up. I had this issue when I swapped heads with a used one that I had decked, the timing marks on the cam gears were both slightly facing upwards. If the timing marks are rotated different directions then more than likely that's just from the belt not being tensioned yet. After getting everything where you think it should be make sure to rotate the motor at least 6 times and see where everything is sitting. The most important part with the cam gears is that the dowel pins are facing straight up. A good way to check your work is by counting the number of teeth on the belt starting at the tooth above the timing mark on the exhaust cam and ending at the timing mark that falls on the tooth on the intake cam. It should be 39 teeth on the belt. If it is not then there's and issue. Hope this helps.

[@Blah4551]

+ausernamenonewants really? lol.... ive only bought 550cc injectors and a rec. intake pipe off classified so far....but upon further inspection ive just moved the cam dowels to the true 12 o clock position and the timing marks on the teeth lined right up...so i kinda feel stupid there...and i also rotated the motor 6 times with a 17mm socket and breaker bar and didnt hear anything bad so i believe everything is fine with timing..

[@tunerrepairsek8907]

cool :D

[@atuaredeye]

how do you put the cam gears back on while keeping the tension?

[@lukegibson1000]

atuaredeye you need the tensioner tool

[@dayanordonez6876]

setup the timing and install a pin un the tensioner

[@nathancruz2843]

I'm doing a cylinder head replacement job on my 98 TSI. Moving everything from my cracked head to the new, and if this video is accurate it will save me tons of time! In the service manual it looked like I was going to have to remove the complete timing belt along with all the other belts associated with it... But watching your video it seems I can replace the head without all the side jazz? This is my first time attempting a project like this, and would appreciate any other advice for a smooth project. I already have the intake off as well as the exhaust (those were simple in my opinion) but when reading up on removing the head, I was intimidated.. Any precautions will be greatly appreciated. Thank You P.S. Loved the ending, I'm glad I'm not the only one those things happen too ha.

[@clutch-slayer]

+Nate Cruz Lot's of people have been using a similar method to mine without having to take off the timing cover or anything, as long as you keep tension on the belt with the cam gears and pay close attention to what you're doing, you should be able to do this without re-timing the entire motor. There's tons of info on dsm forums out there so don't be afraid to read everything you can lol! Also don't remember if I I mentioned it in the video but I like to tell people that there's nothing wrong with labeling ever part you take off, bagging bolts, and taking pictures/writing notes. The first time you do any project is a learning experience so do whatever helps you learn the best.

[@nathancruz2843]

+ausernamenonewants all sounds good man, thank you a ton! video was extremely insightful.

[@schubie02]

Did you need to drain any fluids first?

[@clutch-slayer]

Steven Schubert probably a good idea to drain coolant and oil

[@jdmguy185]

yes drain ur coolant oil u dont need to

[@TheHeadlessHorseman]

but I would change oil after doing the head gasket because some dirt may have gotten knocked down into cylinders

[@anthonyplascencia7526]

not gonna lie this looks intimidating for a rookie. every time my car breaks down I research and youtube and have replaced easy stuff like spark plugs, alternators, starters, water pump etc.. and i always fear ill mess the car up by not doing something right but I've never had a problem. just a fear in the back of my head and looking at this idk if its too big for a rookie like me to tackle but at the same time how will I ever learn if I don't try but then again I don't want to take that big of a risk on my 98 GST. @Clutch Slayer do you think I should save and get it done professionally or do more research and try and fix it myself? I would say I'm a experienced rookie

[@clutch-slayer]

That's how I learned but it's not the best method for everyone. If it's your daily driver, I would let a shop handle it. If it doesn't matter how long it will be down for, take your time and learn how to do it. No reason to rush, label every bolt, do all of your research and don't be afraid to step away from the project if you get stressed.

[@anthonyplascencia7526]

Clutch Slayer great advice :) I would say you came in clutch haha and It is a project car sitting parked so I do have time. Do you have any other tips or tricks or things to look out for when doing it? I don’t want to cause more problems for myself. I’m still going to research a lot more but just wondering if you have any personal input to add

[@anonconformist1504]

@@anthonyplascencia7526 there are several sources to download either the 4g63 engine rebuilding factory manual, or whatever car your engine is in. Those manuals have step by step instructions. If you can prepare frozen food, you can do this. The platform is still very well supported online so get a copy and have fun.

[@StoicFighter]

I think I can do this

[@jakehemauer9102]

What does mean by 6 bolt?

[@clutch-slayer]

6 bolt is an early 4g63. The crank has 6 flywheel bolts. They are usually less likely to crank walk

[@jakehemauer9102]

@@clutch-slayer So is there different types of bolts like 3 bolt or is it just 6 bolt?

[@clutch-slayer]

@@jakehemauer9102 6 bolt and 7 bolt are the only two options. Other than Evo 4g63s which are completely different.

[@jdmguy185]

might be cus i got a 2g but my fuel rail spacers never go past the threads maybe mitsubishi revised it like tht? idk who cares great video though

[@onelowvdub]

omg all that red rtv I stead of grey bond is giving me ocd

[@jdmguy185]

i use a gasket with rtv at the sharp corners

[@onelowvdub]

@@jdmguy185 why you telling us

[@jdmguy185]

well personally i think just using rtv isnt as effective as a gasket but to each their own.

[@robbalinski1606]

There's proper gaskets for every place on that head that's slathered in sealant. a few dabs of sealant for the VC is the only point sealer should be used on the top end of the motor.

[@jameskujawski6651]

Re: with A/C. Please explain in more detail how I'm to get the head off, please ~ time stamp 8:35. Thanks
