Exhaust smoke after sump replacement

Hi. I had a crack in my sump and hadto replace it. After I replaced it I have noticed for the past two days that there is some smoke coming from the exhaust. Is this normal? Is it just burning away oil in the Exhaust system? I think the color is kinda bluish. Not too sure. I also used full synthetic oil. Is this OK?

    Define sump for me, it is a term I am not familiar with, is Oil pan what you mean? Bluish smoke would suggest oil burn of.

It is very possible that there is still unburnt oil on/ in your exauhst and that could cause your blue smoke. Check your dipstick for signs of water or murkiness to make sure that there is nothing else wrong and be sure also to check under your car for any other possible leaks. after parking it overnight, you should be able to see if there is anything leaking a substantial enough amount to cause the burn off you are talking about.

Had exhaust manifold replaced since then my 2001 caravan bucks and blows black smoke little to no power


if you replaced the manifold because it was cracked the look for a plugged cat convertor..the cracked manifold was probably letting the exhaust escape..now it builds too much back pressure

I have a cracked oil sump on my renault megane 1999 model.oil is dripping on to exhaust causing it to smoke.how can i fix this myself. i have been told to use steel putty? will this work or is there a...


Steel putty may work, but it is at best a short term solution and even with the most diligently cleaned and roughened surface, will eventually come loose due it expansion differences in the materials. The permanent solutions is to either replace the oil pan or have the crack brazed up professionally. Both will require removal of the oil pan.

Are you noticing any puddles under your truck? You can buy or possably rent a pressure tester that you just remove the radiator cap and hook the tester up in it's place and pump up the cooling system and watch for leaks. If there are no puddles it must be leaking into the engine from a leaky head gasket or intake manifold gasket. Do you notice excess steam or white smoke from your exhaust? Does your oil look milky? If it does water is leaking into the crankcase. Does it run rough at all? You can start your truck with the radiator cap off and watch for bubbles. If you see alot of bubbles it could be exhaust or compression gasses which would confirm a bad head gasket or cracked head.

  3. Damaged or worn valve guides.

Possible causes:

  1. The PCV system is not working properly.
    The Fix: Replace PCV valve.

Hi, what does it mean when huge amounts of white smoke comes out of the exhaust? otherwise drives ok? it is a renault megane 1.5 dci 2004. regards catherine


Symptom: White smoke or water vapor from the exhaust. You notice white smoke coming from the exhaust when you start your car. If it is cold out, this may be normal. If the smoke does not disappear after the car is warmed, you have a problem. Possible causes:
  1. Transmission fluid may be entering the intake manifold through vacuum modulator.
    The Fix: Replace vacuum modulator
  2. Cylinder head gasket(s) may be bad.
    The Fix: Replace cylinder head gasket(s).
  3. Cylinder head(s) may be warped or cracked.
    The Fix: Resurface or replace cylinder heads. (Resurfacing is not a DIY job)
  4. The engine block may be cracked.
    The Fix: Replace engine block.

There is smoke coming from a crack in the exhaust manifold


Hi

Most unusual for the exhaust manifold to crack, normally any leaks are usually due to faulty manifold gaskets, or the down pipe sealing ring.

I am sure if you lubricate the fixing nuts well, before removal of the manifold, this is what you will find.

Good Luck !

Give me feed back if you like.

A FixYa rating would be Nice...Thanks...John.

sorry to spoil your day but white exhaust indicates that you have a blown head gasket or the head and/or the block is cracked
