- เผยแพร่เมื่อ 23 ธ.ค. 2015
- Join me on this Christmas Special as I attempt to cure a chronic oil-burning problem on this '96 Geo Prizm with almost 240k miles on the clock.
The procedures performed here will apply to these 4-cylinder engines used on Toyota Corolla and Geo/Chevy Prizm vehicles 1993 thru 2002:
1.6L 4A-FE
1.8L 7A-FE
Part 1: Intro and vehicle history, symptoms, plan of attack.
-Pre-teardown compression and leak-down check.
-Cylinder head removal.
Part 2: Piston removal/cleaning, piston ring replacement.
Part 3: Cylinder head exhaust valve cleaning/lapping.
Part 4: Reassembly, start-up, test drive, follow-up.
Enjoy the series, and Happy Holidays!

"Everything you need, nothing that you don't". Damn, I wish they still built cars like this. :(
I'm an old mechanic from way back. I don't work on cars today other then my own. Great video! It's good to see someone that knows his shit and is so methodical and is not intimidated ripping apart an engine to SAVE an old car. Hayes repair manuals come in handy. I can't wait to watch part II. Cheers. Keep up the good work!
Thanks Rick! It's satisfying to get an old worn engine purring like new again with an easy teardown 🙂
Now that's the stuff I enjoy watching the best. Can't wait bring it on . 👍👍
It will be fun watching the rest of the series. Thanks Ivan!
Merry Christmas to you and your family!
AWESOMENESS. Yes, the feeling of satisfaction is surly noticed. nice job Ivan.
Thanks for another awesome video, both from you and Eric O!
My popcorn is in the microwave, I'm ready for this series! cant wait!
Nice work Ivan and looking forward to the other parts.
The A series engine is awesome. I got 180K out of 7A-FE before the body got a case of the crustys (Copyright Eric O) It ran as smooth as day one. Looking forward to this series Ivan. Merry Christmas.
+Toyota Tech Oh 180k is just barely broken in for one of these engines! The body on this Geo isn't bad either...after replacing the rocker panels :)
great videos, thanks for sharing your . Keep up the great work.
Good work Ivan Merry Christmas !
thank you for this series.. btw this is called an in-frame overhaul.. i am going to be doing this to my car before i convert to E85.. will be posting vids for that too..
badass case studies. im going thru all these videos.
These engines with the 5 speed were tough as nails. Love the cam gear design a nice reliable mostly maintenance free design.
+AbandonedSC Oh yeah and super easy to work on! Hasn't burned a drop of oil since the rebuild :)
VERY NICE!
I totally thought someone was yelling at around 19:16 when you were checking number 2 again lol! Had my volume up a bit ya got me, freaked me out hahaha! Great video Ivan
merry Christmas to you and the family have a great day for rainy scotland
You're awesome Ivan. No joke, I didn't want this first installment to end. lol I would have watched all four parts in a row if they were up! Can't wait for the rest.
Bought my daughter a 97' Corolla with the 1.8. Unbelievably reliable. After almost 10 years of ownership, aside from regular tune up stuff, the only engine part I've ever replaced on it was a thermostat! Still going strong. Some oil consumption but nothing major. IMO one of the best vehicles you can buy.
+Baxrok2 Agreed, one of the most reliable vehicles on the planet! That's why I'm excited to get this one cured...no reason it can't go another 200k miles :)
Merry Christmas! Hard at work even during holidays! Always fun watching your videos! Thanks for sharing, looking forward to the next parts
+Angel Garcia so you did not notice that this was filmed in the 12th of December?
+K nope
+Angel Garcia thanks for pointing that out
how would Ivan know that this is 4 part series without finishing the job and filming... right??
Angel Garcia ayye thats my name too bahahaha
great work.
that dude must love that car...
You have to have one to understand
I'm looking forward to this video I enjoy the more mechanical ones. You must have spent some time in a lab you take good notes. I'm going to copy that cylinder pressurization setup.
+Eric Corse Yeah one too many years lol...the garage is basically a lab where you can use a hammer and get your hands dirty :)
I just found your channel through SMA, good job man. God bless!
Hi. The engine has been changed three times already. There been some issues that it was overheating on the first changed. It turns out it was low on coolant also. On the second changed it overheated however the thermostat was not working so there was no way of knowing because it was not working. The fuel pan was changed also on the first change also.
The third engine many parts were changed like the radiaror was change. As well as new thermostat and coolant. The car was low on oil and I took it to the shop just in time. The engine was sounding loudly and might have been stirring. It turns it was low on oil after 2 days that this engine was put it. It was sounding very good and the car had many new parts put in. The car may have been burning the oil. How is that the car burns the pil after just 2 day ls of the engine being replace or leaking the oil. Everything was working fine. We do not what happened. I just on like 300 miles in 2 days time. Then the loud sound started and oil pan light went off and then we check the oil on the engine it was low. Please. We been trying many times to replace this engine and it being done right
Man I'm glad I came across this series Ivan. I'll probably be following your lead in the near future as I just picked one of these cars up to be my automotive guinea pig -something to play around with. It has 308k original miles on it and surprisingly the thing still scoots quite well. I just uploaded some videos about it and hopefully will add some more soon.
Wow 308k miles! How much oil does it burn? I think synthetic oil would have prevented the problem in the first place...
Yeah quite surprising to me too but the more I dig into these cars the more I find out that these engines just seem to last and last. Their biggest issue being the oil burning problem. Mine's the 7AFE 1.8L btw. I think it uses oil as I see some light smoke out the tail pipe every now and again but I haven't driven it much at all. I just did a comp test will post the video later today.
Ivan same oil problem with these engines in the UK. Toyota were replacing FOC short motor only on cars upto 100.00 miles on the clock.Merry Christmas Tam.
Good stuff man. Looking forward to pt. 2. When are you going to make another appearance with Eric O? It's always fun watching The Jedi and Padawan together.
Sure hope you did the compression check BEFORE you drained the oil???
Are there any oil channels running through the Coolant distribution assembly on the 4A-FE engine?
The spring loaded gear is to stop gear chatter and the service bolt is to make reassembly easy because without the bolt the spring inside the gear will stagger the two sections..Just thought I'd clear that up.
+ZIGgassedUP Yeah it's a pretty clever setup!
Restoring compression by fixing the cylinder heads will cause blow-by past the rings if they have a lot of mileage on them. They will lose tension over time and become clogged. Check piston skirt for wear to prevent piston slap & prematurely wearing out the rings you are installing. Did plenty of engine rebuilds after cylinder head rebuilds & new compression exceeding the existing ring tension. Merry Christmas Ivan!
+Robert Hayward So fixing one problem makes another one worse. In this case I told the owner that there is no quick fix; we have to solve the root problem of oil burning first before cleaning the valves etc...wasn't that much extra labor to get the pistons out once the head was off anyways!
+motoYam82 Agreed and the oil control rings is the root cause...I enjoy your diagnostic videos. Merry Christmas Ivan you have a very bright future!!
What an awesome video series.
I have two Toyotas. One has the 2SZ-FE (1.3 - VVTi) and the other which is the high mileage banger has the 1KR-FE (1.0 - VVTi) engine. The 1KR is a 3 cylinder engine, but it is very good on fuel. Its like having a diesel without having to worry about the DPF failing, a dual mass flywheel or blown turbo. It was also much cheaper. I'm starting to get worried about the oil consumption of the 1KR as it must be using half a litre to a litre every 1000 miles or so. I've heard differing stories about the problem. Some say the piston rings themselves are faulty and wearing out the bore of the cylinder and it needs a new short block and pistons. Others say it was just faulty oiling rings and bad design of the oiling channels that would become blocked up, and that you should drill some extra oiling channels next to the existing one when you change the rings.
So an engine rebuild seems like something to try. The car has done 112,000 now. It needs a new clutch sooner rather than later as well so i would probably drop the engine and transmission and do them at the same time.
Most people would probably tell me to scrap it or sell it but i much prefer to keep something if it can still work. Its done so well. It needed a new water pump and i had to put a new battery, new exhaust and 4 tyres on it in 10 years of ownership. I think thats pretty good.
If your rebuild is sucessful that car will probably do another 200,000 miles.
+zoidberg444 You will see the issue clear as day in the next part. Yup no reason the engine can't go another 200k after the rebuild!
+motoYam82 Looking forward to it. Merry Christmas to you and your family Ivan.
Boy I had 95 Escort with the 1.9 Mazda and a 5 speed. I had 375,000 miles on it when the uni body was rusted out. Engine still purred like like a kitten. 45 m.p.g on the highway.
+Glen Harper Those are neat cars too! wow 45mpg?? The Prizm/Corolla will get high 30s on a good day...
Glen, for what it's worth, the 1.9 CVH in escorts is all home grown Ford, the Mazda engine was the 1.8L BP with a DOHC head setup.
يرحم والديك ارجو الرد اته فتحت الكاور وشديته وصارت فرت الديلكو ثكيله اله ترخي الكب الاخير
@motoYam82
the head bolts are 10mm of 12pins??
thanks in advance
A split cam gear to quiet down the valve train?!? Those Japanese people are very clever. Incredible!
It's a beautiful design. Also makes changing the timing belt a breeze 😁
Hey I have a Toyota I did not put oil in it but I did put oil in afterwards and my motor is rattling when I put it in drive it shuts off
I got here because South Main recommended you. i have an '99 corolla 1.8 L that burns a lot of oil. i don't know if it applies to the 1.4, *but the problem with the '99s is that the piston runs a lot hotter than it was designed to run. The oil return holes behind the oil rings clog up with the crud that oil becomes when it is overheated. The fix is to replace the pistons with ones with the new design that has more return holes, **_or you could do it yourself by drilling more holes in the piston grooves behind the oil rings._** There is a great tutorial on the Toyota nation website.*
+Cooll Asice Is it this link: www.toyotanation.com/forum/131-8th-generation-1998-2002/402362-diy-oil-consumption-fix.html
Maybe this video series would be helpful to the forum! There are still thousands of these Toyota engines in service today, needlessly burning through thousands of gallons of oil :)
+motoYam82 Yes. That is the post.
9:51 P0401, Did you have to remove the EGR valve to clean the pipe?
My mothers (late grandmothers) 2000 model Toyota Corolla runs the 1.8 litre 7AFE engine which blows a tiny bit of smoke at 217,000 kilometres but I think that it's just leaky valve stem oil seals !
I enjoyed the series. I noticed your leak down tester only has an upstream (orifice) regulator/pressure gauge. How do you determine leak rates? regards
+Texas Pipeliner The louder the hiss the bigger the leak :)
Hey bro I have a 94 Geo Prizm its burning oil, I have 275 thousand miles on it I need to know where did you order your kit head gasket and piston rings
My motor started rattling on my car because I accidentally did not put oil in it but I did put oil in it my car ran for like 3 days with a motor rattling I don't know what else to do when I put it in drive it shuts down and when I put the car in reverse it shuts off the car does not stay running unless I until I put gas on the pedal and that's when the car stays running so do you have a number I can call or what
I like that
try the pressure transducer on the verus and you probably will not want to use a gauge ever again. scanner danner chanel and tst have great vids on it. great job.
What's tst?
knurl the pistons if your not replacing them.. resize the ring grooves... knurl or replace the valve guides, and do a proper valve grind...
Anyone notice it was tdc exhaust when it came apart.
Im working on my buddies and he been coming to me since it had 116k and its at 403k now, these little cars if tuned an took care of right, it will last forever but its now also going thru hella oil.. I always tell him stick with civics yrs 88-2000si
Compared to my 97 Accord 218k (which I love) , how do you rate this Prizm?
+Steve Allen Toyotas and Hondas from the 90s are both unrivaled in reliability and longevity. I'm a big fan of both. Toyotas seem to have a more durable suspension though...after hitting several curbs, the wheel bearings and balljoints on this one are still original!!!
I saw you're update video and I asked what was the compression test was so the compression wasn't that bad so the proof that a good ish compression doesn't mean that it can't consume from the rings I'm working on a 1.8 turbo VW engine and it consumes more oil than normal and the compression is fine but it can still consume oil thru the rings or the 20 valves seals or turbocharger or the crank case positive system so not as easy as the one you are working on because there are a few possibilities and they are time and part intensive.
+V10PDTDI Turbo engines are known to consume more oil than NA just from the design. First place I would look is the turbocharger itself...see if there is oil collecting in the intercooler.
+motoYam82 I know some turbocharged engines consumes more oil but in general the 1.8 T engine is not known to consume oil it's a different story for the AUDI 2.0 litre 2009 and up longitudinal they are known for bad rings and PCV systems and about the oil in the. Intercooler system I've never seen any turbocharged engine without some oil in the intercooler system the only thing that I know I replaced one injector one time one of the injector failed open and the engine got a great amount of gasoline in the crank case it was driven like this a short distance like I said I did a compression test and everything is okay but like in you're video even with acceptable compression test the oil rings were still not okay if it wasn't you're exhaust valve leak you wouldn't not think that the oil ring would be defective but the 2 compression rings were fine for the millage.
my93geo same qt. every 1000 mi since 100k miles I can live w.that .my Haynes wore out too.
omgthemusic
Wow man
PCV?
What is the correct way to do compression testing? (take plugs out 1 at a time or remove all while testing individual cyl)?
Doesn't really matter as long as you are consistent!
And a full gauge package kind of rare in that era
Just curious if you checked the valve clearance last time? seems pretty strange they would be leaking so soon. Awesome video though! Looking forward to part 2
+Jake Andrus yeah I was surprised too! You'll see the answer in Part 3...
Right on, have a great Christmas Ivan
got a 98 carolla same fix ill
ship it to you
My 94 Corolla only has 278,000 and 170-180 compression, no cylinder leakage , IF it starts burning a qt every thousand miles, I can do this .. but it's still strong! If it ain't broke, don't fix it!
And no crusties! I'll probably have to replace the front brake pads pretty soon. Damn I miss working on my Ford every couple of weeks! LOL not!
its probably orig caused by it getting overheated a few times in its past, weakened the piston rings
My 7AFE burns oil when I accelerate after coming down a hill.
Why are these engines called reliable when the oil burning problem is common?
My corolla 2000 7afe still good, I have been using 10w30 mineral oil into it.
Is this car worth all the labor cost
is the russian flag red white and blue now?
the first time saw that was on smack down wrestling.
Awesome video, terrible music, lol. Just kidding man. Happy holidays.
My corolla still has everyone beat at the quickest startup 😋😜its a 93 DX too :D
1.because Orthodox Christmas Day is around the 7. january (ok, i googled it :-)) happy upcoming xmas .
2. nice video
3. how affordable are you that it is economical to fix this historical car? or is it a collector item? was it the birthplace of Sophie Turner? ok i googled her birth date as well:-).
4. 5stars for the tip you gave eric o. (crankshaft sensor). i had made the same mistake as mr o.
+Paul Grottel Historical Car hahaha that's a good one :) Well this fix is hands down cheaper than buying another beater in similar "excellent" mechanical condition.
Personally I get a real kick out of vehicles that look like they should be in the junk yard, but can still be made to run and drive like new for a small investment.
Is this Chris fix?
"Several Head On Collisions" - that is definitively not correct, and I hope it will never get there, for my sake. Other than that, I am happy that "Turbolet" had such a good reanimator around ;)
+Artem Balashov Ahhh guest appearance by the vehicle owner himself!!
Artem, we'll have to do a post-repair interview for the viewers here after you put a few thousand miles on the "Turbolet"! I want to get the first-hand user impression on before/after power, acceleration, oil consumption, mpgs, smile factor etc. :)
Stay Tuned everyone!
First thing to do would be an engine flush, if you can get it to idle. If its burning oil then the issue is with the rings.
how come you haven't turned the crank top out each cyl
+Daniel K Please be more clear and constructive with your questions.
Don't you have to t,d,c each cylinder to make certain. The valves are closed for a leak test
+Daniel K Yes. That is why I turned the crankshaft 180 degrees between each leakdown measurement. Sorry didn't show that on camera...
Happy New Year!
You started with a mistake early in your video... the Geo/Chevy Prizm is a Toyota Corolla, but they were NOT made in Japan. To avoid import tax Toyota contracted with GM to have the Corolla made in the US, specifically in California.
More specifically at the NUMMI factory in Fremont, California. Which today is owned by Tesla, but does NOT produce any GM or Toyota vehicles any more.
*edit to add... the NUMMI factory closed in 2010, and since then the parts for these vehicles do come from Japan.
Why is this DOHC engine look different from the Acura B-series DOHC engines?
Well it's not a Honda...
Is the car worth enough to justify such extensive engine work?
+MyassesDragon Absolutely, considering this thing is about as easy to work on as a motorcycle lol! Piston ring replacement book time is 10 hours...that's 4 hours less than replacing the water pump on my Suzuki XL-7 haha
at 2:40 what did you do to get it start?
+toolman talal Magic :)
+motoYam82 plunging back the connector for the first injector is magic .... LOL
K ha ha ...lol
did you just do a compression test with the all the oil drained.......
+Martin møller Absolutely.
motoYam82 im guessing that why you started using your red tape for the oil caps :P
Better safe than sorry haha
idd :) by the way i like your videos :) your really detailed with your repairs.
if you should improve on something its camera skills :) like ERIC O :P
Hey bro im mexican, and i have the same car... where i can get the book? Thanks for the video 👍🏻
Hey Zion, you can search for "Haynes manual Toyota Corolla/Geo Prizm" online :)
Thanks bro, really thank you!!
That's why you do not do valve jobs on high mileage engines, worn rings and new valves equals oil burning.
+Bullitt Garage You won't be disappointed with the final repair then!
I have the same engine in my Celica. Why won't this car die? 300K+ and still strong shifts smooth every damn time.
My toyota corolla was Loosing ALOT of OIL i mean LOT like 1 Quart every 3 weeks. Turns Out My Cheap Ass Never REPLACED the Washer on the Oil Pan Bolt and it was leaking thu that bolt but when the wind hit it it would spread it all over the place making it look like it was a rear main seal leak or timing chain leak but nope it was the bolt Washer on the oil PAN. Now it just looses oil from the pistons every 3 to 4 months just a lil bit nothing like before so yeah change your washer on your oil pan bolt ....FML
that run lol
hmm my 95 corolla 1.8L didn't burn a drop. Granted it only had 130k on the clock before I sold it.
+argonian bilbo Did you run regular oil or synthetic? This one got really bad after 200k miles; not sure how much it consumed prior to that.
synthetic 5w30 castrol
ahh that might help with the high temps for sure. I'm putting this Geo on a strict regimen of 5k mile Mobil1 5W-30 synthetic!
I run mobile1 in my 944. Love that oil but its a little expensive. Thats why I use castrol in my daily drivers. Except my truck. Its a daily driver too but gets mobile1. Only has 60k on the clock and is 10yrs old. I use it to haul sometimes so I use a higher quality oil.
Well the little Geo only holds 3.5 quarts so the oil change is cheap, even with the best oil :)
what are you doing ?
+Daniel K Ummmm fixing the car? What about yourself?
It's funny because in UK nobody would attempt to fix it. It would be worth scrap money in UK. Good for techs - they can at least get their hands dirty in US.
+Gregory May Scrap prices over here are like $20 per ton...So this little Geo would be worth less than $30!!!
I think in Russia people would jump all over a used Toyota product, even if the steering wheel was on the wrong side lol! Honda not so much...the roads are too rough for a delicate suspension.
just asking
Pasando vergüenza
The piston ring issue is not a common problem with the A series engines, EGR is common with these at very high mileage. You're thinking of the ZZ Series engines, which the pistons were made small and to compensate, they made the rings bigger.
PCV
19:22 you scared it
When you consider parts and labor, wouldn't it be cheaper to just junk the car?
+siucbset No way man! Toyotas from the 90's are timeless classics, and will outlast any modern plastic disposable cars on the road today. It's a thing of beauty. Ask this question after the conclusion in part 4 :)
motoYam82 Okay, sounds like a winner. I will follow the entire series before I make my assessment.
Pine Hollow Auto Diagnostics frame rots by left rear wheel suspension support rod on these bushing bracket tears out of frame
Its my 1st car and I wouldnt want to sell it. Def the best first best car to have...even today. I see a good handful every week. Sadly, mine's at home sittin on a misfire D: Possibly low compression and the engine isn't responding to the cable and spark plug which DO spark*. (they're new... as well as ignition coil)
Dang this car doesn't worth its worth all this work. Run it till it's end.....
mybe u can buy a cheap motor w low miles on it and be done with it
the motors are a dime a dozon lol
+Jim B A '97 motor with low miles? Where would you get one? That's like playing Russian Roulette...sitting in a junkyard for 15 years does an engine no favors either lol
It is not upside down Russian flag, it is Serbian flag, heheheheh
Russians younger brother
My 93' 177k runs like new, no shit.
