Still sounds like the turbo. Unless you got it from a reputable place I would go back and get another.

SOURCE: O-ring on turbo oil return

if you clean it at the block and put on some sealer it helps,the only way to fix it if your asking this ? would be to pay a VOLVO tech to do it correct or live with it it is very common and is normally not a big leak

SOURCE: Oil in the turbo, smoking bad!

check to make sure the turbo oil return pipe is not clogged. if it is pressure will build up causing oil leak through seal causing it to smoke.

SOURCE: 2001 Volvo s40 oil leaking in turbo, smokes white

Water in combustion chamber makes white smoke--suspect that the head gasket is leaking water into the chamber. If oil leaking around turbo, it may have a bad bearing and bad oil seal. Check waste gate valve and control.

My 1992 Mitsubishi L300 van doesnt run properly. can i get answers?


Your van has a 4G60 series(62/63/64) engine, and is now 25 years old. Loss of power can be caused by many things at this age. Most likely is worn valve stems, leaking valves, and loss of compression. Could be a failing head gasket. The first step is do dry and wet compression test, then a leak down test. If there is a lot of blue exhaust smoke, the engine is burning oil (worn head or/and piston rings). If there's white smoke, its burning coolant, and you have a blown head gasket.

Assuming the rest of the van is adequately mechanically sound, the best approach is likely rebuilding the engine with new rings, possibly rebore for oversize pistons, and a re-manufactured head.

Suzuki atv 350 1989 oil smokes bad before and after rebuild


Hello Lee,
Did a qualified professional do the work?
Is the smoke light grey or black? Light grey is usually oil.. black is over rich carburetor.
Were the valve stem seals replaced?
Was a new piston and rings installed?, Was the cylinder bored and the correct new piston and rings installed?..
What is the compression on this engine after the rebuild? ... Ie should be over 120PSI. !!

please respond on here to me...thanks!!

You are burning oil badly decide to remove head and check the head gasket piston rings and valve oil seals or buy a rebuilt engine from a reputable source as there are some right cowboys selling poor quality rebuilds

Why is my newly rebuilt 5.7 350 chev. Engine burning so much oil. It's not leaking, and not smokeing out tail pipe?


what was entailed in the rebuild?
cylinders bored and hone , new pistons , rings
crank grind and new bearings
or was it just a ring refresh and sand paper on the cylinders
I'm thinking the latter ( cheap and nasty)
The oil will be coming past the rings and being burnt in the exhaust ( cat converter if you still have one )
That oil passing the rings comes from , glazed bores , rings being installed upside down, ring gaps not being set 120 degrees apart but almost lining up
worn ring lands in the pistons
Sump oil either leaks out -- Gaskets , seals filters or is passed by the rings and burnt in the combustion process

My mitsubishi canter 4d32 engine had all its 4 top compression rings broken ie one from each bore what can possibly cause that and what amount of smoke or mist should i expect from the breather after...


As an engine wears the ring lands on the pistons wear also. In addition to ring land wearing on the piston, the bore in the cylinder develops a wear pattern. Has the engine been rebuilt?
If the pistons have worn ring lands and were re-used it may allow the rings (new or old) to twist in the grooves and catch on any ridge in the cylinder, thus breaking them.

When the engine is apart you must check for proper ring land wear. You need to consult the piston manufacturer for proper wear specs, typically around 0.006in.

If you're getting a visible amount of smoke/oil from the breather after the rebuild something is not right. The rings are not seating. I would definitely recommend boring/honing the cylinders and going with a new set of pistons/rings so you don't have to pull it apart again. A little more now can save a lot in the long-run.

Tail pipe smokes alot


This means your valve seals, piston rings, etc. are worn and you need an engine rebuild. The smoke will stop once the engine is rebuilt, as long as it is done correctly.

When i stop for awhil and then i take off it smokes like a blue color it only happens when the engine is hot not cold people have told be it's the valve stem seals and others have told me its the piston...


If it smokes blue only when you first start it, it is the valve stem seals, that is caused by oil seeping past your seals into the valves and when you first start it the seeped oil gets burned on ignition. If you have blue smoke all the time when you are driving, than it is the piston rings, either way you should look at replacing your motor soon with either a good used Japanese engine from Japan or a rebuilt or remanufactured engine.
