Wow! Great find! I'm six redblocks in of ownership and I've never checked that hose for blockage, although I have serviced the breather boxes. Will do so today. 65 and still learning!
Don't feel silly!!! Probably a lot more learning in this video for many people this way! Well at least for me, seeing the whole process of fault tracing along with your explanations helps me more than the one's that only show the end result...
You are not an idiot. If this stuff was simple, everyone would be doing it. There isn't any one of us that haven't had a case of the "stupid" working on a car. Mine was getting the third and fourth cylinder mixed up on an air cooled VW while trying to set the valve lash. I was turning the crank to the 4th cylinder and adjusting the valves for the 3rd cylinder and then moving the engine to adjust the 4th cylinder valves and wondering why in the hell the 3rd valves were so damn loose! After reading the book about 50 times, I figured it out.....and the car ran great after I adjusted the valves correctly.
No Worries, I'm sure we have all been there. I have certainly been there with a 960, if I remember correctly. Exact same hose... Assume... makes an ass of you and me :-)!
Don't be ashamed of what you discovered. It is all about keeping it real and even if it helps just one person then that can only be a good thing. You did the obvious checks and you realized there was nothing fundamentally wrong with the engine.
I had a similar problem 7 years ago with mine. I had too much pressure on the system and was actually blowing oil out of the front seals. It turned out to be a broken nipple on the flame trap. Once I replaced the trap the problem went away and hasn't returned. You live and learn!
No embarrassment involvo'd. You've done well and now I can't wait to check my engine too for the SAME issue of unreasonable oil leaking. TNX for all posts you do. You really like the 240s and 740s almost as much as me! haha (Notably, "Clean Your Flametrap" is a real popular and ingenious web author).
Thank you all the way from Kenya 🇰🇪. Made the same mistake as well. Going to check that hose right now. BTW, I have subscribed as well. Keep up the good work. 👍🏾
before watching this, Lemme guess. The flamelock as we call it in finland? on the hose coming up from the Black PCV box? EDIT: OOOH its the damn hose... time to go look into my hose... bet its blocked too cuz I been struggling with this issue, tho Mine is spitting caskets out due to boost. Thank you always learning new little things here
i went to check my Micra and found I had too much Oil in him and I had Oil firing out of the filler Cap , Not only an overfull Engine Oil level but also .....The wrong length and markings of another Micra engine type Dipstick , What a little f**ker , Been adding Oil by the dipstick level by .5 litres too much for 2nd time since purchase in 2020 (lesson learnt ? Don't trust the things you should trust and search all possibilities ..) Oh and by the way , I used the actual cap , not a glove as it will suck the cap when close enough onto the hole . A silicone glove may become an issue if you get it sucked into the engine I would think .....
Haha yeah, what a trap! 😅 I know what you mean about the glove, I do get worried it's going to pull it in, especially when everything is working like new!
Thanks for the video. I have to go through my pcv system on my 1990 740 this spring. I bought the new flametrap insert and some hoses and the intake gasket to fix the system. I have to replace oil pressure sending unit because it quit working.
Thanks, in the previous video on this car I changed the oil separator box and found it was possible without removing the manifold, just incase your inlet gasket doesn't need to be replaced. Wishing you success with it!
Thanks for this and the previous video. I have had giant puddles of oil under the car. It had many faults. The pcv box was clogged. The nibble on the intake was clogged and the vacuum line crispy. Now it finally sucks the glove instead of inflating it
Hi, I too had the same problem. The clogged and hardened pipe and the clogged ducts. I cleaned the ducts well and put in a new tube. But now the idle has risen to around 1000/1100 rpm. Why?
I'm happy because I solved the problem of too high idle after cleaning the oil vapor filter (the small filter near the injectors). It was the TPS that was misadjusted. It was at the end of its stroke and did not close the throttle body properly. I adjusted it and now the idle is ok.
Did your car start leaking right after you changed the oil catcher? My 940 is leaking and I think it started leaking around the time I changed my oil catcher. Maybe we have the same problem?
I've just seen a couple of your video's and there really good. Leave the mistakes in there as we all learn from it. My 940 has a Buick/Holden V6 fitted to it and I've just spent a small fortune getting the correct rocker cover gaskets for it. Not only that it has now left a small oil deposit on the driveway.
Glad you got it sorted out and it wasn't anything major. No reason to feel silly, these kinds of things happen. I have switched out parts before where the real issue came down to a blown fuse. Thanks for the videos, they are great. Keep them coming.

Oh you actually did, my bad for not featuring the comment! I've got to do the hoses on my turbo as well, they're not blocked but just badly perished, they must generate so much more heat, the plastic timing covers seem to go brittle on them as well
Ironic that I was just having similar issues on my son’s 240. I found the nipple into the manifold Itself needed clearing. It was completely blocked solid. Thanks for the vids. And don’t feel bad- it happens to all of us!! :)

Saving this video in case I need to fix the PCV on my b200k. It is basic though when you think about it. Just find the PCV and clean/inspect every single tube and component. Also funny watching all PCV videos on youtube because there are people out there who genuinely believe that you are meant to have that excessive pressure pushing out the rubber glove. The argument is "It's called POSITIVE crankcase ventilation. There shouldn't be a vacuum!"
Inspired by this after working on 240 and sending it to college with daughter, went out and looked for the flame trap and hose that was Your Answer. Couldn't find the hose on the 940. Where should I look? How different in this function is the 940 from the 240? 1991 240; 1995, 940.
I like the way you wade into the real issues of rescuing old cars and make mistakes so we do not have to. For a lot of us, we fix it ourselves or we walk.
Love watching your videos. I have a 1993 240 Volvo wagon with 84000 and have been working on fixing things like ground wires tailgate wiring harness and hinge ground strap she runs awesome
I wish i had a ultimately quick fix like you had with your redbock. I have the same problem you did of an engine that inflates balloons...except in my 240 i have the rare B23E engine which has the Kjet fuel injection system which is rather different to other redblocks * bet you were elated when you fixed the balloon issue 👍
2nd question: 240 engine heat guage IN and OUT. Bought new Water Temp sensor and Coolant temp sensor. Any insight on these going bad? Any insight on the best path to access these hard-to-reach sender/sensor?
Normally there is a filter type thing in the y-piece, this is notorious for getting blocked. Its about 1" diameter, but some models don't have it. Did you check the large diameter pipe for blockages?
On 3 of my 4 red block 2.3L Volvo's I run a 140 valve oil cap which has a center steel breather tube extension coming out of the cap center and connect a heater hose down to the frame. Any blow-by is exhausted thru the hose, and yes there's some minor oil discharge to the ground. In the states, after 25 years the car is exempt from emissions testing where I live. If needed, you can remove for smog test and use the sealed cap. Search eBay for Volvo 140 oil cap, you'll see the application. 👍
Does the 140 oil cap fit b230f without modification? I don't have space for fixing the crankcase ventilation on my 240 for a while and now I'm too worried to drive with it and risk blowing a gasket and needing even more repairs.
Silly? Not at all. You followed the leads. Almost all of us would have done the same. Good detective work. And good for you for putting this out there so that the rest of us can get to the solution faster. Thanks.
You are NOT stupid or silly mate ,,This is a learning curve,,Give yourself some Credit You’ve found a potential problem and sorted it ,,IF we all knew straight away what the answer to all the problems of a Volvo Engine We’d All Volvo Technicians,,,Don’t put yourself ,,YOU are doing something others Wouldn’t,,,Keep up the Good Work,,Loving the videos,,,,Budgie Bognor Regis UK
I like to use the oil dipstick hole instead for the glove. With valves and cam moving under the valve cover there's a lot of activity and moving air /gases.
Really glad it turned out to be something this simple, glad we could help. Travis was spot on, hats off to him. I'm chuffed about the honorary mention for 2nd place though! :P My 240 just got a fresh TÜV sticker today - old Volvo's just aren't made to die.
Great follow up! So happy for you and the 740! Those compression numbers were great too. I was cheering them on as each one climbed. Great video buddy!
Wow that's a great find! I am so thankful for UA-cam comments sometimes. Just imagine where we'd be without the internet! Nothing embarrassing about this and I wouldn't feel ashamed or a little bad. It's called learning and you learned before doing a major job and then finding out nothing changed. Great video as always! You make me miss working on my 240s! I can't wait to get my 85 out of storage and start making videos of it again!
I sometimes want to upload the problem first, wait for the comments, then fix it 😅 There's alot of people that know alot of stuff and being Volvo guys, mostly friendly too! Can't wait to see the beard back on the 240s!
I thought that I had an open vacuum hose to the intake manifold, but it turned out it was nearly clogged. Replaced it and now it works perfectly fine. Glad I didn't have to replace the oil trap 👍
@@Involvod Oboy, that's awesome! A couple of videos ago I said that I bought my first 240, your videos have already helped a ton! I'm looking forward to the gasket video!
You obviously know your way around these engines big time. I’ve only seen two of your vids so far, but your approach to troubleshooting is fantastic, and remind me why I love the B230s so much.
@@Involvod not that bad, untill an exhaust stud breaks off in the cyllinder head. I got it out though, good as new now, except for an erratic idle it developped. Going to buy a smoke tester soon I think.

Cheers! Sounds like a hassle, but surely a better motor than those Renault ones they fitted at the factory 😏
Ive had a 740 and 940 that both needed new breather box and cleaned flametrap/ hoses. Seems its an oft overlooked system.
Yeah definitely, out of sight, out of mind perhaps!
Glad you got it sorted out and it wasn't anything major. No reason to feel silly, these kinds of things happen. I have switched out parts before where the real issue came down to a blown fuse. Thanks for the videos, they are great. Keep them coming.
Yeah, always got to start with the basics eh 😄 Thanks again!
Great find, well done. Always good to see the faults found and fixed.
Cheers!
going from the compression test it's a healthy engine.
That vacume hose: good find !
Thanks! It's always a relief to see good numbers 😌
New bits n bobs and shinny clean things on an old motor cant be bad :D
No it certainly needs alot of them 😅
