OMG! Cam Lobes Dropped....
Okay,
we were removing the cam and did everything the instructions said but the instructions said nothing about the cam lobes dropping. It said remove it slowly to make sure that the cam lobes not to score the cam bearings. They said nothing about them dropping down. Now we're having to retrieve these.. any suggestions how how to do that? and what the **** went wrong? Also is this a major crisis or an easy fix? Thanks..... :(

They all fell into various spots I.E. sitting ontop of the connecting rods to the pistons, oil pan, block, etc. We have no idea why this happend we followed the instructions to a nats ***. We evenlowered the sub frame like it said to. I have no idea if the extreme angle of the engine allowed them to fall that way or what. But he should have listed a warning if thats what was going to occur. We've fished out 11 of the 12. Also i'd like to know if the lifters need to go back with the corresponding hole they were in. If thats the case we're FUCKED! Sry for the language but im a little upset now. Any and i mean ANY advice helps right now. Thanks guys.

Good rule of thum is to keep the lifters in order... But the roller lifters in a 3800 should tollerate being installed in another location... Not exactly a good thing...
I have installed the lifters in my 91 without keeping them in order...
If this was a race engine I would demand that the lifters be put back in the same bore that they came out of...
Reinstalling them in another location should not do them any harm... I have seen many roller lifter engine go back together with the lifters in a diffrent location...
My next question is why you guys did not remove the valve covers, intake and then the pushrods so that the lifters could be pulled fromt the top as this is a pushrod engine, the Cam is what holds the lifters up...
And to top it off how come the instructions did not have an explanation for this?

we assumed that the lifters would stay in there positions but apparently not and we did do it in that order. But the directions said nothing about removing the lifters. Untill after the cam was removed did we realize what happend. I guess bad luck. None the less we're trying to get the last lifter and then instlal the cam and put the lifters back in place. Add the new timing etc. so i think we're okay now. Also how much would new lifters cost? And would this be a good idea to buy new because of the present circustances?

I would reccomend better lifters with the new cam... You could reuse the stock lifters but if there are any issues with them you will kick yourself later for not replacing them when you had the chance...
If you have the $$$ for the lifters, get them as well

This may be a sign for you. In my research, I have learned that new cams come with this little recommendation: Install NEW lifters.
True story: When I took apart my L67 and discovered half (yes, half) of my existing lifters collapsed due to poor maintanance, I spent many hours trying to clean them out. I was able to get all but two of them working well enough to put back in. So I went to Autozone just to buy 2 lifters. BUT...they only sold them in boxes of 4. But the price was right : less than 15 bux per box. So I said, "Gimme 3 boxes". After comparing the new ones to the old ones, the old ones had WAY too much cushiness to fully work properly.
In other words: new lifters will give your valves more time to stay open, giving you more power. Besides, if the old lifters are worn, they will wear down your new cam. Do yourself a favor and just get new ones. It'* cheaper than having to get a new cam again!
EDIT: jr beat me to it
