Blue/white smoke DD PLESASE HELP

[spyke1019]

'87 cabby Stock manual
I let my roommate borrow my car and asked him to check the oil before he left, he put in a quart to fill it back up, but either didn't put the filler cap on or it fell off. Car ran about 60 miles before I got in it this morning to go to work. I stopped to put gas in and noticed there was more smoke than usual and found no cap, so I added 2 quarts of oil and put on an old fuel cap I had. It worked until I got to the auto parts store to put on the new cap they had, it didn't fit. Put more oil in it and fuel cap back on.

IMPORTANT>>>Too much^^? Basically Almost ran out of oil from lost cap, tried new one, FAIL, put in 3 qts oil, Then \/\/\/

Before I got 300 yards down the road plumes of blue/white smoke shot out of the exhaust as I hit 4th. checked for blow-over and that wasn't it. I had to drive it about 1.5 miles from the auto parts store to get to a place to pull off and had it towed home... What could cause this? Only plumes at higher speed, not lower or idle.

Daily Driver PLEASE HELP!!!
Did a search and mostly found turbo issues and smoke on takeoff after idle... this isn't it..

You say you added oil, So I would assume that you checked the level first before adding as too much oil is a bad thing?

Actually if you have a windage tray, you don't loose that much oil with a cap off, there is very minimal blow by.

I would say you toasted a ring or burned a valve....
What was the oil pressure?

[rabbitnothopper]

i did this too, although mine was caused by a plugged oil pump baffle

checked oil
oil low
add oil
check level
level is good
go driving....60mph and huge white smoke clouds
pull over...check level...out of oil
WTF......
noticed the breather (air box) was dripping oil..or i mean pouring oil
ok............
drove it home like this

decided $500 was a good investment to tear down the engine and rebuild a lot of stuff

discovered in this process:
factory rod bearings
worn piston rings
piece of plastic lodged into the oil pump pickup tube......

55,000 miles later still driving it

Correct, no oil on dipstick at all

No Windage tray that I'm aware of as the rest of the car is mostly stock, I assume the only way to check is to remove the oil pan??

I did not notice oil from the airbox, however everything else sounds the same, could you possibly provide a list of the $500 rebuild that I may have a better chance of keeping this one on the road as well.

No there are 2 the windage tray in the oilpan, and one on the top of the cam. If you remove the oil cap and can't see the cam directly, then you have a windage tray.
If you can see the CAM then you are missing one.

I can see the cam, so it has no windage tray

also you will want to get the improved valve cover gasket with studs.

My wife did that on our diesel, left the cap off. Took a 700 mile drive.... There was plenty of oil on the hood, engine, tranny, dripping on the ground, but only about 2 cups in the engine. That was the day Slick 50 was worth every penny...... OBTW it was a 81 Diesel rabbit that she did that to.... They didn't have windage trays back then....

Anything I can check to try to find out about the valves? Oil pressure on VDO was normal

[briano1234]

You can pull out the spark plugs to get a clue as to which cylinder it may be that is giving you the Grief, as it may just be one Cylinder.

Then to the compression tests and see if they are all the same wet or dry, that is you will take a reading per cylinder, then squirt a little oil in the cyl and take the reading again. This way you can possibly narrow it down a tad bit more.

I'll have to do that this afternoon, I can usually rent a compression tester from auto parts stores, correct?

[backinthegame]

Brian is spot on. One more thing to check. Look at your air filter. Is it covered in oil? If you overfill your oil, this is where it ends up. It then gets pulled into your intake and causes blue smoke.

So apparently in my haste to make sure I had enough oil, I overfilled itOil change and cap as well as air filter tomorrow... I can't believe I did this
I've seen oil filters with less oil in them.

yes you can rent a compression tester from autozone for $40
it has two adapters


recently did the same thing

remove fuel pump fuse, remove center spark plug from distributor or coil

remove all spark plugs
test dry rotate about 4-5 times on the crank (starter)
take the reading
add about 1-2tablespoons to the cylinder (it will remain wet a long time)
test again and take readings

Should I bother checking compression now that I know I overfilled the oil?

[spyke1019]

I have corrected the oil level, and have a new air filter but how should I clean the system from airbox to the engine? Carb+choke cleaner???

[spyke1019]

Will carb and choke cleaner through the airbox clean out the system of the oil?
