Oil is coming out of my exhaust?

I have a 1971 Shovelhead that the top end just came out of the machine shop. For some reason, the motor is using too much oil. So much, that it comes out my exhaust.Where do i find a diagram for my S&S oil pump? Please help with suggestions on the oil problem.
Thanks
Rick

If the s&s oil pump was installed during this build you need to pull it back off get a drill jig and drill a hole through the case which is tough with the motor installed but ask your parts guy he should be able to get you a kit from s&s or jims pretty sure that will solve your prob

1) new rings put in upside down, the dot on the oil ring should be up when installed on the piston.

2) Valve guides and or valve stems are shot

Not really any other way for oil to get into the exhaust.

    To get out the exhaust the oil HAS to come either around the rings or through the valve guides. An upside down oil ring can certainly cause this type of problem. There is a dot on the top ring. It should be UP on the piston. If not it will never seal and oil will scream past it. You should certainly see a lot of smoke when you back off the throttle as well.

Why is my 1971 super beetle's front end violently shaking at 35 mph?


could be several reasons
loose front suspension parts
wheel alignment
faulty tyres
steering joints worn.
failed wheel bearings
loose wheel studs
I suggest that you take it to an accredited front end specialist shop and have a complete safety check done to determine which parts are faulty.

I have dismantled my 2008 Street glide's Top End to diagnose a screechy sound from rear cylinder. I have found nothing wrong. I suspect it may have just been the exhaust gasket as it is crushed out....


Well, I don't work on Twin Cam engines but I've rebuilt all sorts of Harley engines in my life, mostly Shovelhead and Evolution engines. I can't comment on the "screeching" noise other than it may be the chrome covers on the exhaust pipes that are held on by hose clamps. The exhaust gasket is supposed to be "crushed". The crusting on the top of the pistons is carbon from the combustion of the fuel. If the carbon is dark black, it indicates that the fuel air mixture is a bit rich where brown or tan would indicate a proper fuel air mixture. A clean piston top would indicate a dangerously lean mixture and the top of the piston is running hot. One of the changes in the Twin Cam over the Evolution engine is the use of oil jets to cool the tops of the pistons. The oil is squirted from underneath the piston onto the underside ot the piston top. It helps tremendously. I've never seen a valve guide leak oil on an Evolution engine and the Twin Cam engine is designed in the same manner.

Good Luck
Steve

I have a 1997 863 bobcat with a 4 cylinder Duetz engine. It takes oil out of the crank case and blows it out of the muffler. I had the turbo rebuilted. That did not fix the problem. Can someone help...


Did you notice, when you had the turbo off, if you were seeing evidence of oil in the exhaust manifold? It's got to be coming out of the motor or the turbo, one of the two, and determining which is the first thing to do.

Pull the turbo off and look in the exhaust manifold for oil. If you see oil, pull the manifold and you should be able to determine which cylinder it's coming from.

If you don't see oil or a heavy buildup of carbon in the manifold then the turbo is the suspect.

Are you certain that the oil return from the turbo flows free?

Do you idle the machine long enough at the end of the day to allow the turbo to cool to reasonable temperatures? If not, the oil in the bearing will cook into coke, causing the bearing to run dry the next time you start the machine, also it can cause the turbo to leak.

Get back with me, let me know what you're finding out.

1999 ford winstar engine problem


Either the heads are cracked, the cylinder walls are cracked, or the head gaskets didn't seal properly. You need to check your catalytic converter/exhaust, there probably is what caused the problem & accounts for why the smoke is coming out of the top of the motor, it can't escape through the exhaust due to the blockage.

good luck,

sometimes a used motor is less expensive than repairing one that is bad & especially if you get a warranty.

Oil leak


This is normal on a two stroke. The exhaust is held on by a couple of springs. The motor is burning the oil that lubricates the top end, smoke from the exhaust and oil leak is normal. You might check your ratio, a good ration is 50:1

Blowing oil

1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse


You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.
