After many close calls in my life as a mechanic I scored the big one that puts me in the running for the Engine Darwin Awards. I was taking the cams off my 348 engine and to expedite things I used an air ratchet. Of course the inevitable happened, one of the nuts from the bearing caps flew off and quickly made its way down one of the oil passages and into the depth of the engine even though I had the head partially covered. After some explicit language I tried fishing with a string and magnet with no luck.... so I retired to the living room with a bottle of '85 Ruffino Riserva Ducale Oro (great year) and laughed at my stupidity. Anyway, in my attempt to save a few minutes I just scored several hours of extra work. Short of picking up a 800lb engine and tranny and flipping it upside down and shaking it - what are my bests options to correct this major scr&w up? Take head off first? Remove transmission and pull oil pan? TIA for any suggestions. Franck
Trans can stay but the pan needs to come off. Congratulations you're not perfect. Stuff happens. Lots of good uses for an air ratchet....thats not one of them.
Well. I am going to assume the basic block and head construction is more or less 308ish like. I lost a washer off one of the bearing caps working on mine. My God, there are 20 caps, thats 40 nuts and washers you can fumble. Sooner or later we all goof. Its just a matter of time. And I tried the magnet. No luck. But it would have made no difference. So I sat and thought about it over a beer. (I didnt have a bottle of '85 Ruffino Riserva Ducale Oro handy). Not knowing the cost I probably couldnt afford one anyway. Anyway, as I couldnt see it, It had to either be under a valve, in which case it would be impossible to find without pulling the head, or, it had gone down the oil drain. So I dropped the pan hoping, and fully expecting to find that little washer lying there cute as you please. Nope. Actually it was lying up on the ledge of the gearbox, just beyond reach of my fingers. It had dropped down the drain hole, through the block and thats where it landed. I poked around with a coat hanger and it fell out. Lucky day. At least Ferrari made the holes larger than the nuts or washers so they fall through. So, I would say that if you cant find it up on top, pull the oil pan and keep looking. Until you get that lil feller in your hand, or are absolutely sure its not inside there somewhere, dont try to start it. If you get really frustrated, send me a bottle of that stuff and we can chat about it more I supose being a dry sump, pulling the pan off is a real beach isnt it.
Jagbuff, Had the same thing happen to me before. I had a rag over the head that I thought was so convenient, I'd use it to wipe off my hands (fool). Down went the nut. I went fishing with the magnet only to lose my "lure"! Dropping the pan made me all smiles for the rest of the week! Tada the magent and nut were hiding around the corner. Give it a shot.
... I figured that with the irony of the situation I would grab an Italian wine that would be commiserate to the amount of time or money that this is going take to fix... the intended effect was achieved. Now I am more sober now, oil pan seems to be the way to go...
Unfortunately the propulsion unit is out... so I will grab another bottle of Ruffino and start wrenching
Would it help if you could see the nut/bearingcap? http://www.toolking.com/productInfo.aspx?productid=12868&pricegrabber=SLIPV100&
If you have access to a video probe it can be used to locate the nut without disassembly. Any QC shop should have one. If you were in Iowa I could hook you up with one, it is sitting in my office right in front of my desk. The camera head on mine is about 1/4". I have used one to locate a nut I dropped through a carb on my car and was able to monitor the recovery on TV. I also have a magnet on a nylon stick that works better than a string.
Jagbuff, nice choice of wines! If I am not too late did you try a magnet mounted on a more rigid material than string? I have a magnet mounted on a soft metal shaft like a coat hanger. Allows a bit more aggressive "fishing". You may ask why I have such a device? Because I too have traveled into that dark realm of "Oh Sh#t"!
QC Shop - Quality Control Shop? What kind of radius can you get with one of those - it is very tight corner probably 1.5" radius - if I try from the top of the engine. Can you rent then?
First try one of the other nuts with a magnet. I've found several fasteners on my car are not magnetic. (Guess how I found that out )
Yes. http://www.mtmcardle.com But the link that I gave you earlier just charges $211 to *buy* one. Anyway, I'd think one would help. Then I'd try a high powered shop vac to see if I could recover it. Or a magnet on a string/stick/flex-rod. If you have to drop the pan then you may still have to use compressed air or an oil/coolant flush...just depending. Good luck!
I am going home and going to try the magnet/ nylon rod approach coupled to vacuum, at this time I have nothing to lose. Probably will spring for the borescope, cheaper than the headache I got this morning from drinking that bottle last night
Before you go throwing money down for a borescope that may not reach all the way down anyway, why not check one of the other nuts, make sure it's magnetic, and spend a whole bunch of time fishing for it if it is magnetic. If that fails, maybe try pouring in a bunch of engine flush and opening the drain plug and let it gush out. That might be enough to get it to roll out with the flow. If not, then go fishing again from the bottom through the drain hole. If none of those things work, just drop the pan and be done with it, IMHO.
Just got back from Radio Shack with rare earth magnets, mirrors claws.. Will report back on progress!
Some of my favorite tools are an assortment of different magnets (including one on a nylon shaft). I fished a 10mm nut from deep in the bowels of a 365 GT (it was laying on the timing chain near the bottom, borescope wouldn't have seen it). It took a couple hours of trying, be patient. Magnets are handy for reassembly when your fingers keep getting in the way.
Now what an interesting thread. Guys dropping tiny metal bits into the bowels of megabuck Ferrari engines just to figure out cool ways to retrieve them. Ya'll just need a reason to buy that $211 bore scope. You dropped that stinkin nut in there on purpose didnt ya? Honey, I want to buy this really cool tool. It might come in really handy. No! We cant afford it. Sounds from inside Ferrari engine "tinkytinkitytinktinktinkitytink". Well oh darn, would ya look what I did. Uhmmm, honey?
Thanks for everyone's input. I tried the nylon guide and magnet for a while and gave up after multiple attempts, no matter what I tried no luck. I opted to remove the oil pan - turned out to be quite straightforward and pretty quick - less than an hour for sure. I got the prize and drank to it!!! Now what is the best sealant to put that pan back on - suggestions Thanks again! Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
