reasons why your oil pan dissapears off of your car!

[Malice]

so i got a new motor put in 2 weeks ago by a reputable guy. and tonight as im drving down the road at 30 at around 3grand i heard a thump under my car and sparks are flying outta the rear of my car. i get out look under my car think it was my hanger and dont notice anything i get back in my car and notice my oil light is on so i turn it off. look under my car again and my oil pan is missing! wtf so i call the mechanic and he said i ###### through a rod because i ran it out of oil. for one i checked it the day before and it was fine. would anyone like to guess or tell me why it fell off... thanks in advance...

If the mechanic was any good he would have checked your cars oil after putting in a new engine and there is no way that in a couple weeks you ate all that oil and shot a rod, i am guessing, and call me mr obvious... GET A DIFFRENT MECHANIC! he is no good and probly his fault the oil pan fell off.

 

[Malice]

i have a 3 month warranty on the motor...

 

[sureshot971]

dont you think its a little weird tho that the mechanic swaps a new motor but never checks the oil? in two weeks you arent gonna burn so much oil that you shoot a rod, that would be the mechanics fault not the cars.

His damn Oil pan came off, never burned any oil. He had no oil cause the freakin pan came off haha. Sorry to hear that man, hope you get that worked out.

hahaha I was about to say..Uh...? You beat me though.

The only way that the pan could come off is if those bolts aren't tight that hold it on. Even for it to fall off for that reason, there are so many of them, they would have to be REALLY loose. Maybe the guy that put in the motor, if he built it, or whoever did didn't put all the bolts to hold the pan on, and didn't tighten the ones that were put on. I don't see how anything else could have happened.

How long did the car run without the pan. How many miles, and minutes. If you can remember.

Or, he used sealant and didn't put ANY bolts

That is quite odd.. I'd figure out whether the bolts were installed or not.

Not any more.

while reading i was thinking about saying that thing about sealant, but you got it first
the guy probably put on some sealant and the pan stick onto the block, so the guy even forgot to put the bolts on OUCH

 

[wolf20043]

Sounds like a HUGE mistake by a so called reputable guy. If it is warrantied and you still trust the guy , You coud have him pull all the bearing caps to make sure it was not oil starved from driving without an oil pan, but personally I would look more at a refund and him to pay for any and all damage and do the work myself. Be it the last guy or the mechanic mad e the mistake, the mechanich should have made sure everything was tight, including parts he did not put on.

If you were about 30 miles more south I would take a look at it for you.

That has to be what happened. A stick of dynomite inside the oil pan wouldn't pull all the bolts out.

I agree. I have had rods break and push through the oil pan, but never lost any bolts.

I think this is really ironic, and crazy. Wherever that oil pan is it must be messed up. Because i know on my 91 u have to drop the exhaust and transfercase and Axel to even get the pan off, so thats really ironic. But my guess if you want it. I believe he broke most/all of the oilpan bolts when he put them on prob put them on with a ratchet gun, or impact wrench who knows but thats crazy. Because the bolts get rusty and old after a while, i know u have a 97 but still thats all I can think of.

Good luck and I would sue him and get an Evo

And to back that theory, you can just look underneath and see if the studs are still in the bottom of the block without the heads on them. Those bolts are pretty easy to twist the head off.

inspect the threads of the bolt holes, if they are fine then your reputable mechanic forgot to tighten them

How would looking at the threads in the holes tell anything? You want to be able to bolt, and unbolt something, and the threads be fine. Am I missing something?

Not at all Bro. My point being if there are studs still in the block with no oil pan, the bolts were probably WAY over tourqed, But I do agree that threads in the hole just means either no screws or tourqed and came out (very not possible)

[RoasT BeeF]

There is noway a rod would make the entire oil pan come off. It will just punch a hole. Either way that guy should be fixing your car no questions asked. Keep me updated on what happens. I know another guy who just had a motor put in by this same guy and his is doing fine so far. The more I read about this guy the more horror stories I am finding about him though.

Keep me updated man and let me know if there is anything I can do to help you out.

 

[DSMcrazy3]

I was quoting the other guy, not you wolf.

4g's have studs? I'm use to mine that has regular bolts...I agree with the sealant theory though.

Naw Bro. I was referring to the bolt studs. Meaning the heads are gone. But as far as Roast Beef said, I know what you mean Bro, heard ALOT of good about him , but some things I am hearing are spooky. I was just hoping it was not that shop.

Yup, that's my guess too. If all 20 bolts are now gone, it's probably because they were never there.

Yeah, really. It's about time someone said this. What are the odds that EVERY single bolt came out at the EXACT same time? Forget about sealant - they still wouldn't have all come out at the same time.

They were never all in there to begin with. The mechanic forgot. And throwing a rod would not knock the oil pan off! That really ruins the credibility of the mechanic!

inspecting the threads would tell you alot! if the threads are fine, it tells you that the pan didnt get ripped outta there by force (either no bolts were used at all or loose bolts that worked themselves out)... if the pan did shoot out with bolts still intact, the threads should be mangled like a mofo!!!
