my friend is having a problem with his turbo del sol. It has a b18b1 engine. When he is driving and takes it to high RPM's the tubing with the BOV pops off of the IC tubing. What could be causing that. When I looked inside the tubing there is oil in it. Is that bad? Could it be something serious? Also is the turbo manifold suppose to be really hot? I put a drop of water on it and it just slid right off. It seems like it is hotter than normal. I need to know something ASAP. I am posting a pic of the tubing that pops off the ic tubing and a pic of the oil. Right now I have part of the tubing off so I can cget the oil out of it.

 

UH-OH... thats not good holmes

 

seals are fucked. time for a turbo rebuild.

also u need to soak that FMIC in like acetone or gasoline asap so it doesnt get baked on the inside of the intercooler and make the FMIC useless..

good luck.

 

What seals? The car seems to drive fine. The tubing never popped off until he ran up on a curb. I looked under the car and nothing is damaged. How much would a rebuild cost? What is the FMIC?

 

He is talking about the turbo seals.

When the turbo seals are shot the oil in the center cartridge of the turbo gets pushed into the compressor where it ends up scattered along your I/C and charge piping.....

1) You need a new turbo, or at least a rebuild
2) Like someone else said, your gonna want to soak your I/C with some solvent like stuff to flush all that NASTY gunk out of there.
3) Turbo manifolds do get very hot, its normal

 

How much would a turbo rebuild cost or a new turbo? Is it really serious? will it mess up the engine if it is driven? Why do you think the turbo when bad? The tubing did not start popping off until he ran up a curb but I checked under the car and nothing is damaged.

 

I rebuild turbos, trust me as a professional, its bad... turbo seals are very delicate and very suseptable to damge.....Is it serious. Well that depends on you. You sound new to turbos, so i'll elaborate. Turbo's spin upwards of 200,000rpm (in some cases) at full spool.... so you can imagine the kind of stresses going on inside one. yes, it can mess up your enigne, the turbo uses the engines oil to cool itself, if you're shooting all your oil through your charge pipes eventually you'll run out, then boom..... Why did the turbo go bad..... any number of things, dirty oil, not enough oil, too much oil, wrong type of oil, dirty being sucked into the compressor...... the list goes on. An easy cure to the charge pipe problem is to run a bead of weld about .75inches from the end of the pipe, the tighten your hose clamps on the other side of that..... should eliminate any problems with street use. We charge anywhere from 300 to 600 for rebuilds, depending on type of turbo and severity....... sometimes more.

 

Weld a bead around the edge of your charge pipes to keep them from blowing off. Otherwise the silicone connectors have a very slippery smooth metal surface to try and hold onto, and they blow off very easily.

 

When you hook it all back up again (after the rebuild) I'd recommend putting a needle valve in the oiling line to the turbo. That way you can adjust the pressure on the seals (25 psi at around 5000 RPM is plenty). A gauge after the valve would also be a good idea so you can read the pressure (without it you really don't know). Make sure the gauge is liquid filled and rated for medium vibration or its going to come apart (in otherwords a $6 gauge won't work right).

 

what kind of oil am I suppose to use? the guy who sold me the car said I needed to use synthetic oil? the oil is not dirty because I just changed it. I did not put to much in either. How would dirt get into the compressor? This is the type of turbo: Garrett T3/T04b turbo .60A/R

I guess my friend is going to drive it until it messes up b/c if I tell him about it he is going to get so upset because he does not have his permit yet and he said he would hate to not drive the car when he gets his permit. Could going up the curb have caused it? I dont know how long it has been like this but the cars seems like its driving fine? Would it be cheaper to get a new turbo or get it rebuilt?

 

next time you change the oil use 20w50 and the blown seal might not leak. Are you burning oil too? Driving a turbo honda without even having a permit? Sounds like a death trap to me... I'm just jealous, I wish I had a turbo anything back when I first got my licence, it took me a long time to afford one.

 

when i blew my ring lands oil was pushed through my turbo. but i guess you would also see smoke. might want to do a compression check for the hell of it.

 

Do you wnat to buy the car?

 

How would oil get in the charge pipe?

 

There was not really oil in the turbo.

 

oil gets in the charge pipe when it goes past the seal in the center section into the compressor housing and gets blown through the charge pipes.

 

is that normal? There was no visable oil in the turbo.

 

take the pipe that connects to the compressor outlet off, and take a look.

 

what about oil feed lines. could be too big. just curious suggestion.

 

that's probably why the seal blew in the first place (feed pressure too high), we run restrictors on vw's to drop the feed pressure a bit, you should try it if the thicker oil doesn't solve your problem.

 

If the seal blew wouldnt there be alot of oil in the turbo and in the intake pipe?



Is the compressor on the left side of the picture? If so there is no visable oil.

 

not necessarily, because there's oil that leaks past the seal into the compressor housing and becasue the direction of the flow of ait in it the oil would travel with the flow of air. What picture? Just clean all the oil that's in there now out and change the oil to 20w50, there's a good chance it'll fix your problem.

 

You might want to also check your oil return line. Make sure it's not coming down off the turbo then back up to the oil pan. And make sure it's not kinked. It should be at a angle to were all the oil can drain out of the turbo once you turn the car off. If not oil will will sit in the turbo and cause the seal to go bad. Also i think your checking the wrong piping. Check the pipe coming off of the turbo leading to your IC (intercooler) for oil. Not the one with the air filter on it.

 

Can you see the picture? isnt the compressor on the right side of the car? If so isnt that the one with the air filter? If there is oil in it is that bad?

 

it just means ur seals are going out if not out already
