I forgot to add oil after I drained the car, the car ran for no more than 5-10sec.?

Question

There is a small small tick but I believe the tick was there before i changed the oil. The oil pressure light is off, so what is the chances the engine now has damage???

Answer 1

used to work at a ford dealership, while performing an oil change on a crown vic i forgot to put oil back in to the engine, (got sidetracked on another job). started the car and let it run for a while till the rods started knocking, shut it off and filled it restarted and let run till the knocking quit. today's engines are remarkably tough. my money is on no damage done. and by the way the owner never complained to us that the vehicle was knocking or any problems at all, just kept bringing vechicle back for its maintenance.

Answer 2

The chances of doing any damage to the engine are remote. Even though you drained the oil there is still a residual film on the cylinder walls and in the bearings that will lubricate the moving parts. The 5-10 seconds won't do any harm, particularly if the engine was cold when you started it. I wouldn't worry about it. A ticking noise would be from a valve or lifter and that would fix itself is it was due to low oil pressure. If it is a valve out of adjustment or a collapsed lifter the noise won't go away. The tick did not result from running the engine without oil
hope that answers your question

Answer 3

No damage, but that's another advantage of synthetic oil. They've run some engines for hours after a synthetic oil drain and the engine continued to run. You get extra high temperature protection when you use synthetic oil. Besides, the quick lube trainees probably do it all the time and the customer never finds out about it!

Answer 4

Probably no damage.
I had an old Toyota that actually blew all its oil out when the pcv valve stuck on it, and the engine seized before I could pull off the road. After it cooled off, changed the pcv valve, refilled the oil, topoiled the cylinders, and after about 5 attempts, it started right up.
Of course part of that was dumb luck. I had the clutch disengaged at the exact moment, the engine seized, so it didn't break any rods.

Answer 5

bummer. im not sure about the 50,000 mile claims, but it all depends. the weather, how much oil your car consumes and how clean your engine is on the inside. if it only ran for 5-10 seconds, you should probably be fine, but i would wait a little while to see if the ticking goes away before consulting a mechanic. if it doesnt go away relatively soon, then get it checked out, but you know how easily a mechanic can just tell you you need a whole new engine after eharing your story.

Answer 6

A LOT DEPENDS ON YEAR OF CAR.. MOST NEWER CARS WILL SHUT DOWN AUTOMATICALLY WHEN IT SENSES PROBLEM LIKE NO OIL. YOU SHOULD HAVE ENOUGH OIL STILL IN CAR THAT PROBABLY WOULD HAVE PREVENTED MAJOR DAMAGE. FOR THAT 5-10 SECONDS. THE TICKING NOISE COOULD BE A LIFTER. IF YOU HAVE NO WARNING LIGHTS AND THE OIL PRESSURE IS OK I WOULD JUST MAKE SURE TICKING NOISE DOESNT GET WORSE.

Answer 7

It will be ok just put the oil in and let it run for a while , 5 or 10 sec will not damage it.

Answer 8

Slim to none. I would check that tick it is a rod hitting the block that is bad. But the engine most likely still had oil in the engine and still in the pistons. ou should be ok.

Answer 9

i think your ok as lng as it was omly for a couple sec... the oil all never comes out of the engine so you would have some lube still in there so there will be no damage. i worked for dodge and it happens from time to time and no engine damage occured(except diesel engines) so you should be good to go. just try not to let that happen again.

Answer 10

This happens to certified mechanics who lose their train of thought for two seconds. Just put the oil in it, the oil pump should still be good and will pick up and circulate the oil. Life lesson.
