Are you sure your not talking about an Accumulator ?i reconmend an aquasump when the oil is all used up the aquasump releses more its controled buy air.

I was also shown an oil accumulator system by 82911 that did the same thing. It was a large cylinder with a piston that filled with oil at engine pressure and feeds back in should the engine require more oil than the sump can hold! It was moroso brand and it was an accumulator as struggler mentions!
I'm hoping that i dont need anything so drastic. Realistically my engine really isnt anything amazing or special, it's just a reasonable 400 chev! Nothing too trick!
Thanks again for looking and for your thoughts though! It's all helpful in knowing my options!
Cheers and thanks guys!

You have to remeber that chev, holden or ford have allready spent thousands of dollars and years of development on their motors on just the stock parts on stock motors ( way back to the 20's ). Ive heard stories ( rumours ) of guys working in car plants and when they start / test a block, they would rev the absolute crap out of a fresh motor. If it died, send it to be fixed, it if lived , its passed its first test. My opinion is the car companies have done a great job (except for the piston slap in the first ls1's / holden / chev really #@$^%& up there ).
Look at some stock 308's that have had the living crap flogged out of them and are still going using stock oil pumps, fuel pumps, rods and cranks, etc. As long as the oils changed when due, Its usually the box or diff that give up the ghost.
I guess what Im trying to say is, you see heaps of guys mod a standard motor to the extreme only to find its unstreetable or it dies a horrible death real quickly. A damn shame. Imagine if you had spent that money on a standard rebuilt motor, and it went great ( can still spin the bags , if so inclined

Im not having a shot at Tiny or anyone , as Tiny has already stated its just a reasonable standard chev, but i feel for hime as he has had some of the worst luck, but everything is repairable ( if you throw enough money at it)
Its just sad to see allot of young guys here worry about motors and spend all their cash and not look at important things like brakes and suspension.Honestly how often are you going to drag/race your everyday car?
I hope I havent offended anyone, I didnt mean to, just dont like seeing cash being wasted.

Chop: Thats exactly what i was thinking mate! I didnt need it before, i'm 99.9999999999% sure that i wont need one now! As i mentioned it really is a fairly reasonable chev.. nothing trick or fantastic!
Torana: Julian, Far from being upset, i can see what your saying! The R&D time and effort spent on these motors from the day the first line is drawn on the drawing board till they day the cease to exist is phenominal. Not only do the factories spend billions on making an engine to do a specific task, there are hundreds and hundreds of after market shops out there trying to fix the little weaknesses and inherent design compromises so that you can tailor an engine to suit your needs.
For some people a standard rebuild type engine, or a crate motor is the perect answer, and we are VERY lucky in that recently ( last 2-3 years) this option has become economically viable. Previous to that a crate engine could cost alot of money and time to source!
The other thing too is that the tollerance of a crate motor CAN sometimes leave alot to be desired!
Having said that, for some people this is a great solution, but i decided to follow advice given to me by many different sources and decided to rebuild what ive already got!
The reason the pickup broke and the cam bushing fell out was because i DIDNT listen... and i re-installed the gear drive system that i had. I'm convinced that the harmonics and vibration that is transmitted from that gear drive has been a cause in this and subsequent damage.
Having said all this, ive learnt an umteenth ammount, and i really enjoy learning about and tinkering with the engine internals and its workings. I just wish it wasnt so expensive!!
As simmo said.. it all happens at once.. were having a pretty bad trot with everything.. but thats farking life.. and we will soldier on!
Cheers!

Modified engines are fickle things, I'm having a ball with mine at the moment.

That sounds quite logical to me. Just a shame that sometimes we have to learn things the hard ( and normally expensive ) way.

We'll get there in the end! Its just a long and expensive road... but hopefully with a few enjoyuable timeslips along the road!!
How do yu mean your having a ball?? Dramas? Or your really enjoying it? (Judging by your parts list i recall.. it was always going to be a big task but a highly rewarding one!!)
Chop: Yeah thats right mate, Almost everyone told me to take it out for these very reasons.. but for whatever reason i didnt! An thus there is no one to blame but myself!! And to be honest i dont really care... other than the money its cost i knew it would happen one day!
Its all good! Thanks again for the well wishes and i'll be sure to keep you all updated! Especially my first real Dyno graphs and then the 1/4 mile passes to see how much we've improved!!
Cheers!

No one realised that SCAT cranks are internally balanced! meaning i now need a new balancer and flexplate! AND that means that we get put back a few more days.....
Just as the crank and rods and all were perfectly balanced and everythign was looking rosy!!
I just cant win this week!

Sorry I should have mentioned that all aftermarket FORGED cranks are neutral balance. Also check the size of the snout, as some Eagle and Scat cranks run a different sized snout.

I'll give mark a call tomorrow and make sure he orders the right balancer to suit the scat crank!
Thanks

Yours is a 383 right?And so it continues!!!

Pretty sure SCAT make both cranks in 383 form, either internal balance like all 262-350 were or external like 400's were.

It turns out there's a footnote reference in the SCAT Parts book to look at but its pretty well hidden!
So basically i'm up the creek!
Thanks anyway!

Ive learnt something today.. Standard 400 checs come with a 5.56" long conrod. NOT 5.7" long...
And when you combine that wit a sexy new scat crank...the counterweights hit the piston base.....
So... TO cut a long story short... I'm up for a set of rods and pistons to suit the new crank. I really cant belive all this! Talk about a learning curve.
And while were at it.. i AM going to up the cam shaft.. THe old cam had some not-so-nice marks on the tip of the lobes that seem to indicare a porous cam casting so were going to go with a new cam and lifters.
Blah. I hope work picks up....

You probably dont want to hear this mate but bear with me as I am in a similar boat....
Throw enough money at it and you can fix anything lol I know this to be true as I am doing the same thing

It went from a $900 "sump and pump" to $6000 odd rebuild... I just cant belive this! Every time we touch something we have to change it!
AAAARGH!
