Thanks man!!! 5 years with my 740 and never check that PCV box until my car starts leaking! 😂
Really enjoying these how-to style vids, might do this with my 940 turbo when I get the chance
Thank you, just what I needed to know how to do for my 740 Turbo. Been leaking for the 6 months I have had it, just found out about the flame trap clean, but didn't know how to do it.
Just bought my first volvo 740 turbo wagon!!
thanks for putting this one together man! been something Ive been putting off for a long time
thank you for doing this video man! Was dreading this job but I may do it this weekend! Cheers
Things seep oil everywhere after 30 years! Definitely true, if you have the cash replace all the rubber hoses because at this point the rubber is just falling apart especially in hotter climates.
Thanks for this bud, i just got a 940 turbo and am gonna do this asap
Awesome info man. Got this issue with our S40 big time.
Has to be the issue!!! Thanks much
No worries man glad i could lead you in the right direction!
LOVE the intro.. So classic you
Thanks you are one of the few who even own a 740 Volvo, with a stick trans, this car is unmatchable as far as a car for driving goes and easy to "Kick-Ass-on the road too, it just sticks to the road if you know how to drive; the one I have is a 1988 has 170.000 on the speedo, car must have been used as a student project from Wyo-Tech, because all of the left side of this car was simply torn All-to-Hell, it was as if they were trying to figure out how one of these cars comes apart, because they just cut everything up and made a mess of the inside, I start trying to find out why i had no head lights low or high beams checked all of fuses, i did find a blown fuse for the high beams and when i pulled the lever to bring them on, it blew the fuse, as i was digging around under the drivers seat i found a plug in for the lights which brought me high beams, But still no low beams and no blown fuses, no current at the lights no viz able broken or cut wires, switch is good because the tail lights work. This is amazing this will be the first time I have run into a car that has a low beam head light issue where most of the people i have contacted didn't have any clues other then "That Car is Too Old"!! I went through the all of the books or guys who had shops even the dealer here in Oakland California, only to find out not one person could give me information.Robert the Volvo repair guy seems to only work on fluff or PicnPull cars, not much detail repair. you were right the P.C.V. vent box tend to plug up this one was not bad although I find 0-5 weight synthetic engine oil won't carbon up because it doesn't break down under extreme heat. i checked the timing belt and found it to be a bit loose and just moved the set nut to remove the slop. i have a slight leak of oil at the distributor, where oil will leak down the back of the engine, i do believe there is an O-ring in there. As i dig through my 740 i will put some information out on what I find out this low head light inoperative problem. Also I will bring up some of my experience Racing Volvo, and all of the "Hurt" feelings I ran into. Glad to see there are still a few 740 people out there.
Thanks this video helped alot ive got a 940 turbo and when i give it gas so the turbo spools it spit oil from the dip stick and oil fill cap hop this will fix these problems👍
I know this is an old vid but love the vids👍🏼keep it up
I've just got rid of the box on mine using the plate that Yoshifab sells and a catch can... and a B20 vented oil cap for good measure. It was spraying out oil under heavy boost previously and now it seems to be ok.
You r the KING dude!
Hey what did you use to cap off the IAC valve off? Love your vids man one of the few people who understand the potential of 240/740/940s, cheers.
My 740 Turbo started leaking out the rear main seal a few years ago so I sold it... Wish this video existed back then. I loved that thing.
you obviously didnt love it enough
I bought my 745 turbo knowing it had a rear main seal leak… 3 years later still drippin’
With my 91 the egr assembly is located exactly next to it. I took off the intake for room and still struggled with egr valve/ pipe. Mission complete, but an oil leak is still present. I'm wondering if I should have made a gasket on the bottom of the box. When I go in next time I think I will high temp gasket the bottom of the box ensuring a proper seal. Good video dude
He's right.
I've owned 4 of these, I always do this and all/any leaks stop. My last 740 completed 250,000miles still with a dry engine. Volvo's seals are made to last and will do so with the slight negative crankcase pressure created by this.
Good advice.
Good video, thank you for not putting music (noise) in your video.
Ohh man, there is not so much guy who work with the 740. And a got one 87’ B230E, red block of course. So thanks for all information, actually I have used various of them myself on my Volvo 740 GLE. So I. thanks!!👍🚘
Very welled explained thanks
Hey ya, where do you get that strut bar brace? (not sure of the name), the green one. Totally agree on the pvc system, also check the egr if your car has one. Most modern cars have a similar issue. The systems that reduce pollution do so by trapping all that nasty stuff in the car as a opposed to spitting out into the air. Volvo was really ahead of it's time with these. Another thing to check is that the path to the evap canister is free from restrictions.
I just replaced my RMS.
Looking at this video, I remember I still have to do this on my 740.
Not sure if the b230k model has it.
what do you think of replacing these oil separator boxes with an oil catch can? if you've done that
Hey man, how r u holding up? Hope recuperating well?
why didn't you just delete the pcv? I removed it partially on my V70R. did you have to replace the mainseal?
Totally doing this! (As soon as I have some time hahaha)
Before i started watching your videos i actually did not know about this trick, and have never seen or heard of anyone in Sweden doing this! Now this just might be me being deaf and or blind though. But this does not concern me anyway as i have the 760 with the v6. Love your vids btw and greetings from volvo land!
I replaced the box in my Volvo 940 Turbo last year after reading about it on volvo 7/940 club. This guy is on point. It can spare you a whole lot of troubble.
Good Job.
you are Volvo king........
Can you use muriatic acid for cleaning the pipes and whatnot? Thought that might be a effective way to clean it.
Have you had to swap out many fuel tanks with all of your Volvo experiences??
Den stora frågan är kan den börna?
Klaang klart! Det är ju en volvo
Klaang bjuu börn dåå
Do you think it could be the same issue on a 2.5 straight six 960? Obviously it's a whole different engine.
But there's a person thats selling a gorgeus 960 near where i live but he says it's and i quote "Sweating oil"
I figure it's an easy job to just replace the top block gasket but i was wondering if there's a possibility it's something else.
EDIT!: Ended up buying a 945 b230fk with m90 box and its dripping oil very slowly and very minimally from somewhere in the engine space. We took out the oil return pipe from the turbo and put some new gasket and tape to properly seal it but it seems that wasn't it. Search continues
When is clogged that can make your car loose power or when start the engine and let it warm up sound like bubbleling
I soaked mine in de greaser and then stuck a hot pressure washer into it. came up spotless.
thumbs up bud
Are the inlets for the heater core on the firewall directional meaning, can coolant only flow one way?
Hola amigo,,,,buen video,,,,,,queria hacer una consulta,,,,,,,en la pata de valvulas se ve un cable que va conectado a la tierra en la parte inferior derecha,,un cable ancho, ese cable va conectado en un tornillo a la carcasa junto con una caja negra cuadrada, que tiene mi volvo (gl 740),,que por dentro es un metal recubierto,,,esa caja no lleva ningun cable,,,,,,tu sabes que funcion cumple esa caja negra,,?,,gracias,,saludos desde chile,,,,
You should reach out to IPD to see if you can get some sponsored parts. These are real cheap. Ordered replacements from them instead of trying to clean them these parts because of your vid!
I had a valve clicking but once is warn is ok but when you move forward is like running out of power I thought it was the distributor spark plug wires and spark intake gasket and manifold gasket I did transmission change and angina service and nothing I don't know what that could be or if is a vacuum leak
Hi .can you tell me where does the canister hoses should be link .by a video please.
Did this and my car makes a crackling noise near radiator at startup, could i have knocked something loose?
Its because there is stuff mounted in front of it, the way you take it out, on some models. In order to get the stuff in front of this out you need to take the intake manifold away.
Now you know.
Can you tell me where the boost sensor is located?
Friend, I have a Volvo 740 from 88 that when I turn the key the car won't start for nothing! I already tested the fuel, the air and ignition are ok!
Any suggestion to solve this problem.
help!
My 84 244 is leaking oil I think that's clogged I'm gonna do it do I have to replace anything else?
Your videos have me snail trailing in my underpants
Dude FUCK the oil separator box, lol. I've changed mine twice now because my "OEM" new one blew apart.
Braden Carlson yea they're a pain , I've heard of the replacement boxes falling appart.. that's lame as fuck
Does this apply also to the 1988 760 Turbo?.
I thought you had to remove the intake manifold and throttle body to do this on the 940 glad to know, how hard is the rear main seal to do ?
You do. Anything 91 and over (740, 940)
Is this part in the 1984 volvo 244dl?
it's the same on the whiteblocks volvo PCV S/V/850:s Common issue!
i was gonna do this on my volvo 945 but there is a valve of some kind that is covering the 2. bolt and not sure how to deal with it. greatfull for any help.
The valve of some kind is easily removed. Take a 22 mm spanner and just loosen the two nuts retaining the metal pipework. The top mounted pipe is secured to the inlet manifold, remove the 2 10mm bolts securing this to the manifold. Then continue to remove the 22mm nuts, the metal pipes will ease away, careful not to loose the olives and small gasket at the inlet manifold. A 24mm nut hold the valve in its retaining cradle, remove this and the valve can be left gently supported by the 6mm rubber hose. You now have access to the breather box bolts that also secure the valve cradle. 10mm bolts may also be securing a section of wire harness to the cradle, its best to remove these at the same time.
Interesting, my 240 is pumping the oil into the air flow meter, which is causing it to run badly. The oil is saturating the tube going into the intake.
K techie question, do you think this being clogged would cause the car to smoke? My sons turbo 740 will smoke bad while idling at a red light, doesn't do it all the time, just randomly
smoke means the car eats oil, that might be a bad headgasket
So, what was it?
always replace rms when trans is out. I made the mistake and had to drop trans again because rms failed
He broke the lower hose holder of the oil separator box, it stayed inside the engine.
Maybe it didn't cause a leak?
My question is if your Volvo has started to leak small amounts of oil, will replacing the PCV stop the leakage or is it too late?
Hey, 3 months old but thought I respond with my results. I had to go the hard way. My Oil return hose ( line off the PCV into the block) totally disinegrated, it was clogged, corroded and in several peices. This video is on point good stuff for sure. I had no choice but to use the WWW.CLEANFLAMETRAP.COM Method. Dropped front end, IN engine bay hoist, Dropped oil pan, sump screen totally obscured by plastic hose peices. Flushed oil system 5 times. Installed entire new system, reassembled, including busted motor not otherwise identified. Oiled her up, ran SEAFORM thru due the 387K Odometer read. Having concluded no one had ever serviced the PCV. Car History 1993-1998 Car was Volvo lease to Co. 1 driver who buaght it at 5yrs old (50kmiles) from Volvo Leasing as he was the OG drive and continued until I (with 2 college age kids late 90's, I'm no delusional on who drove it)I buaght her in May 2020. So serviced same place 27 yrs. No record of this service. I go at length becuase no one ever goes that far to ensure the bottom end of this system is clear and the possible irreversible damage. If nothing else this is a cautionary tail, and a testament to the 230B durability. Prior to repair replacement I drove 1100 miles 15 hrs straight from point of purchase home. BTW, I did finde service records that the shop recommend 20/50 wgt oil. I do not!, I still have the "snail" trail and I am doing the front & back seals, timing belt asap. I'd rather have a small leak then a clogged system for now. Good luck.
I need me a Volvo
Heay What u used for cleaning? asetone?
brake cleaner
Get a tripod or one of those gorilla grip tripods so you can film yourself actually doing the thing. It'd really improve your content!
i have volvo 940 turbo
just cut the oil cap seal and no more pressure in the system... work on the s70 as well
Wouldn't this have a negative affect
@@ethixhiggins5059 would it flip a check engine code ? maybe but no pressure in the system to blow out seals …..neg is youll sooner or later loose some oil to it venting out as steam....but cam seals/rear main are not ez to do for a normal driver just expert car people...$1.00 seal (oil cap) or $ 400 cam seals ? should you change out the pcv box yes but in the mean time you can have no pressure in the block..
@@AwakeDude911 i do not want to tackle the rear seal on my 940. Thanks for the tip it actually comes of great help. I need to do my harmonic balancer and waiting for the timing belt kit to do that and the seals and i was worried if I did those if it would be pointless if i didnt change the pcv box first but I feel like it would be okay with this quick patch until i get the pcv box its on the way.
What do you mean "oil cap seal"? The seal on the cap where you pour the oil?
@@ett_baer ...yes thats the 1 or that the seals off the oil dip sick also works ...you need to let pressure out of the block with out the oil spilling out...
Anyone know if I can pull my PCV box out of a carbed 740 like this? (i.e. without taking the manifold off?)
Did you ever get an answer for this?
cant that be on 940 turbo to? in that case would be a very easy fix
yes its the exact same and it makes a big difference.
Jimmy Augustsson yep this pcv box should be cleaned on any b230 powered Volvo ! 240 740 940
sweet, i will try this when i get to the volvo soon, might be easy to sell :D
Jimmy Augustsson at the same time when cleanin pcv u should clean intercooler and pressure pipes
I can use brake clean and a screwdriver and I won't damage the box? I don't wanna replace the box either lol and I'm about to do this job.
If you buy an aftermarket box don't be surprised when it comes apart at the seam. I just clean them out like D&L...
Wassap
Where is that bottom bolt
A How to fix video but yet he's saying you'll figure it out😂🤣
did you even watch the video?
lol
@@l00pdigga42 holy crap this is a year ago that I comment on this
You know I would just dunk it in purple power.
#1 cause is piston rings
Literally its dumb easy on the 740. Try doing the same job on a newer volvo like the s60. Lol its 200x more difficult. Rather do the pcv box than a crank seal or rear main.
Phillip Gagliardi. I've done 2 on the p2 cars so slurp down my long on 😏
i would love to buy those usa headlights. so sexy ❤❤
Pvc should be done on the whiteblocks too, significantly more of an arsehole job to do though
HI someone had cut that small hose on top on my car allowing oil to leak out of it I guess altho not a lot over time it has gotten on everything below, funny how the mechanics who work on my car never mentioned it and I have asked them to clean the oil and check it. They are so fucking lame, they have never done things they should I've had to learn and do everything as a woman, they suck.
Half ass helpful- did it fix the problem or what ???
