SOURCE: Oil running out my tail pipe

Excess engine oil can only enter combustion chamber from four areas, (1) the intake manifold [pcv system failure], (2) Valve stem seals worn out [pluged oil return holes in heads causing oil to get sucked past worn seals] (3) Worn/varnished up/broken piston rings,(4) Highly unlikely but a hole in piston. Since you only show excess oil on left rear, suspect #2 or #3 although usually more than one set of rings will wear out or (gumm up).Check compression with all plugs out, ignition & fuel disabled, i believe 120 to 150 psi is good, if ok , check #2. If this has the older efi intake, its rare, but also could have a failed intake gasket for that cylinder and be sucking oil from underneath.Hope this helps!

SOURCE: cylinder 3 misses and has carbon biuld up on plug


U got a bad piston rings! U have to pull down the PiSTON to replace the PiSTON RiNGS, oil is getting in ur combustion!


Check also the valve guide oil seal, hope that is the faulty one! 'Cause replacing PiSTON RiNGS will cost a LOT!

Check on that first, Oil in ur air filter means a BLOW BACK gas from ur combustion is pushing the oil into the air filter!

BLOW BACK is a residual combustion air that should have been burned or gone thru the exhaust, but w/ poor seal of ur piston ring, it goes into ur CRANK CASE and into ur EGR system w/ excess oil!

Hope that explains everything!

Possibly a leak in the head gasket. Take out the plugs and see if they are water wet. Run a compression check.

My 95 chevy van smells like its burning oil and smokeing out the tail pipe

Sounds like you may have a huge oil leak, this is a common problem if the chain is not done correctly on the chevy V6 or V8 engine. Go under and look, bet oil is all over the place and getting on the exhaust.

White smoke coming out of the tail pipe after taking off.

White smoke continuously blowing out from the tail pipe ? If it is only at the cold position it is normal, if it is always coming out it means oil consumed & compression is week. spark plug frequently needed ? If plug frequently shorted u need to overhaul or need to add oil treatment for increase viscosity.

Blows oil at of the tail pipe

If it is blowing oil, you have bad compression and bad piston rings. At a minimum, pull the plugs one at a time to see if they are oil fouled and clean, then replace them. That may get it running.
