1993 245 B230F 316000km PCV oil drip hose missing.

Post by sergitin32 » Sat May 16, 2020 10:50 pm

Hello forum mates,

I am trying to reinstall a missing PCV oil drip hose that fell into the oil pan... I already disengaged the oil pan and fished the old hose out of there, now I have the new one and because of the lip or flange I can only think it goes from top-down, but there is no way on earth I can find how to install such. It does have a certain fold here and there which makes me think there is a proper "right path" for it to go through the crankcase structures but not a clear idea on what this pathway is.
I obviously don't feel like fully dropping the pan since it involves either doing it with the pump simultaneously after lifting the engine and losing the driver side (Canada) engine mount or a bunch of other work if just taking the pan out. Anyone has done this job before? Any advice? I have all new parts to get the whole system in an as new shape, the pan is loose down there and the tranny front flange piece is also down... I just need to get that hose in place to resume with the rest of the job.

Thank you.

Hey, Rick here with what may be the same issue. I've opted for the drop the motor mounts/crossmember/rack & pinion, and built a engine bay lift from channel iron.
I've cycled the engine oil thru nylon 5 times to remove what was left of the corroded, errodide, crumbling 27 yr old "oil return hose" and Seafoamed It with 5gls of fuel in the tank. ( Seafoam High Milage 1/3 fuel tank, 1/3 valve cover, 1/3 sipped thru the fuel pressure line.)
The hose is flanged at the top with a tab that fits nicely between the PCV/Breather box and the engine block. Tappered hose, with a "dogleg" or race terms "Chicane" at the top 1st, 4' inches. Over all 12'. My Haynes 76-93 only has the early version and it's not talked about in the forms. They ignore it, or warn that it's a pain in the ass. I've got my new breather kit I priced together. Flame trap, both short and long hoses, breather box or PCV, and our notorious Oil return hose/ oil sump line, sump return pipe, and Oring. I've read that some have deleted the return hose altogether?! Purest agree not a good idea. For lack of better judgement, advise, or wantimg to do this again. Im going to cut the ladt 6' of my pipe/hose off, coat with oil, and push down from the top under the intake. Ou will see the space on the bottom of the PCV where the "Tab" on the top of the flanged hose should rest. Thus creating a washer sleave type fit into the block. Clear as mud I know.There's room be patient. Share pics?

Is this the same as what you're working with?

Hey Rick,
Thanks so much for all this info and the pictures, yes that is exactly what I am dealing with, I simply did as you said and slid it into the block form the tops, I actually did not notice the detail where the little flap goes in that notch, that would give the hose the right orientation, great I will double-check on that detail later. Thankfully my hose was intact there and it came out in one piece.
My only gripe now is that posting in another forum someone told me you'd actually need to remove the oil pan in order to attach the bottom segment of this oil dripping hose into a bracket inside the block so it doesn't rattle around and knocks on all the moving parts, I guess it makes sense, I will try dropping the pan (not completely but just getting it loose again in order to take a better look inside with the hose in and with an endoscope to see if there is a clue to where that bracket is and how could I sneak a hand in and make it happen. If there is a bolted piece of sorts then forget it, dropping the pan is needed and I am trying to avoid such a pain. my work conditions are really the worst.
Cutting that hose short or getting off the system is not a good idea since the lower tip dips into the oil in the sump that means gas pressure inside the crankcase won't be affecting the pressures inside the box and make the system malfunction. As well that's why you don't remove the baffles in the pan around the oil intake of the pump since you'd like the oil to stay as much as possible there when turning etc. Anyways mine is in already, the whole thing I will check on the detail you showed me and maybe in the future take a look on how to attach the inside of the hose to the block wall for the right setup.

Good to go. I believe the "channel" the pipe is guided thru is the 1st 4 inches is the only thing inside the block thus the dogleg in the pipe. I'll be making a post of my lil adventure. Working condition are all low budget and DIY here, but I have the time tho... 6am and my garage is already over 90° Vegas!
So no issues with oil leaking after replacing your pan and not a new gasket? Thats my main reason Im doing this after of course replace repair the PVC. PO (previous owner) said he was was using 20/50 weight oil. It was really boggy, but on open Highway she was warm and good to go, city driving I had to rev her alot to get rpms. Now purrs like a kitten, rpms are quick, well Volvo stock quick for 380k @27 y/o. What brought you to the PCV debockle?

Well, the car was dripping fluid everywhere, this got my attention towards changing the PCV box and the flame trap to improve the pressure in the crankcase but then took the box off and noticed that dripping hose was gone. I thought to myself the only way out of there is in, and I was right. Even when I knew I was gonna sell this wagon (same color as in your picture but a '92) I wouldn't sell it like that so I needed the work done. When you say only the channel in the block to guide the hose, do you have any pictures of that channel? I tried with my hand in there to touch around as much as possible and do think I touched some sort of like a bracket but just touched not visual so I wasn't sure what it was for, really, so I decided to simply drop the hose with the best orientation to avoid the cranks. There is very little info online on this topic so I am not sure what would I be looking at in this case. Something pressure fitting the hose inside or with a bolt to hold it?

This was a moderator's comment in the IPD forum: "The hose you are speaking of is inside the block. It is only attached in 2 places. The top of the hose has a flare that is held in place by the spigot on the bottom of the oil separator box. The bottom of the hose is held in place by a small simple bracket bolted down near the oil pan. There is no way you will get to this bracket without completely removing the oil pan."
So it does look like there is something down there to hold the tip of the hose... dang it.

I am torn between doing it all over again or just tell the buyer what's going on. Since I have to sell this car in the next month before I move out of province, I do all my mechanics from a car stall in our building underground parking. Temperatures are my least concerns, neighbor complains and fines are, plus the space for working is minimal and I have to work very late hours to avoid been caught and blamed, I would love my own garage... ;)

No worries, I think your good brother! I took pics hope it gives you peice of mind. I think your good to go, clear your conscious, it's all good. That "bracket" I moved with a flat tip, slipped that doglegged "pipe" with the "tab" at 12:00(front bumper 12 o'clock, driver side 9, psngr 3, rear end 6. Ok?) so it hugs the inner wall down the block into the pan. On the pump theres a "lip" at the bottom and thats where the line ends. So if your bolted down on the PCV. LEAVE IT! You've done more then most well ever do. Cowards! Flame trap it just the tip of the iceberg. No where can I attach these pics? Brb?!

Oh man, thanks so much, them pictures do grant me peace of mind for sure, I can see now that the hose needs to get the curve to hug that side of the block wall and it should slide inside that bracket just by following the wall.
What I will do is remove the box again just to make sure the small tab in the hose is pointing 12' as you explained before. Then just leave it there and don't think about it anymore.
Feeehhw, I was really struggling in my mind with dropping that damn pan again.
I will just leave it. And move along the project onto some bodywork (fixing holes in the rocker panels)
Thanks a lot for your help bro, enjoy the Volvo life!

Thank you! That's the piece that's missing from almost every PCV issue forum, YouTube, even the Haynes manual. Be well, good luck with the sale.
