Freshly Rebuilt Engine.. Oil Use

[GTAAAH]

Should a freshly rebuilt engine use more engine oil than one that is run in?

Just curious as i've gone down from full to half on the dipstick in the last 2000 km's since having it rebuilt.. Can't see any leaks but haven't had a proper look for em

EDIT: Engine is forged everything, standard turbo's

How often did you check the dipstick? Gradual usage? Some engines do burn some oil while the rings bed in.

Top it back up and see how it goes.

Also try doing a search cause this has been covered in quite a few other topics.

Ah ok cheers, It'd be roughly 1000km's for the rings to bed in though right? The oil got put in after about 1000km's (so 3000km's total since rebuild) Hopefully it's a leak somewhere, i wasn't losing this much b4 the rebuild.. Can't think of anything else it can be

Also i just checked oil and it's almost on L so thats like.. 1 litre of oil i guess in 2000kms

arent they 2nd hand turbo's kieran? if they are.. you dont know what condition they are in... oil seal in them might be gone and could be burning away your oil!

[GTAAAH]

yeh one of them got replaced when it was in getting rebuilt because the oil seal was gone, but i'll get it up on the ramps at the local tyre joint and check it out in case they missed something, but that amount of oil usage will most likely be a leak i am hoping and not something gone wrong with the build, right? If it is just a seal i'll leave it till the -5's are ready to go on, cheers dude

Mine took a while to stop using oil.

Oil usage was at its highest in the first 1000km's and then slowly tapered off until ~5000km's is where it wasn't using any.

Wiseco forged pistons with the std ring pack, slight slap on cold start up. The motors done over 100,000km's now and still doesn't use a drop.

your a crazy man for putting standard turbos back onto a fresh motor!!!!

They didn't put the rings on upside down did they?...its happened before.

[skidkid]

Have you had a look at plugs? Is it using oil on all cylinders? Is it blowing much oil smoke out the tailpipe? Are you driving it very hard?

That's something i've never thought of.

Eh don't say that, that would not be cool.. The workshops rebuilt a heap of rb26's though so i think they wouldnt make mistakes (or i hope)

"Mine took a while to stop using oil.

ah thats good to hear, I'll hope mine does the same and tapers to 0 usage, i did spend 1000km's doing all the ring bedin processes so assumed they'd be fully bedded already.. It's reasonably slappy on startup, pistons are oversized CP items

"your a crazy man for putting standard turbos back onto a fresh motor!!!!" (i don't know how to multi quote shhh)

Yeh i'm only running 10 psi on them and they've been thoroughly checked and are in good condition so i'm not so worried about them blowing up on me..

[GTAAAH]

Haven't looked at the plugs yet, i'll check em out tonight when i top the oil up and get back to here

It doesn't seem to be blowing much oil out the tailpipe, but it normally runs rich as hell so it's hard to tell what colour it is.. Not driving it very hard, mainly just to work and back and not revving it much yet either (for some reason i'm still scared it's going to blow up)

cheers

I couldnt agree more.

Considering a stock turbo can and WILL kill a motor if it fails... (how they 'checked' the turbos without pulling them apart ill never know...)

Putting stock turbos on a forged motor is not smart at all @ the risk of killing a built motor

[GTAAAH]

Yeh i would have liked to put some new ones on but i owe the old man $10k for the rebuild as it is, still paying the car off, couldnt afford another 4k, I assume they just checked them for play and checked the condition of the wheels on em, i believe the majority of these things only fail because they're being boosted too high, i'm not exactly pushing the car and the boost peaks at 10psi so it should be right until i can afford some new ones

[R31Nismoid]

4k for turbos?

... Garretts are $1300ea

[GTAAAH]

Yeh, but then i'd have to baby it for months until i could afford a power fc and a tune (thats the $4k), and even then have to have it tuned carefully so i wasnt maxing out the fuel system..

bahh good points made, going to get a loan extension tonight, 2860-5's, pfc and a tune to keep the power below 300kw's till i can afford the z32s, injectors and pump

Easy tiger - while it may be a bad idea to put the std turbos on a freshly built engine.

I think we need to remember that these can and have travelled 100,000kms with no issues at all...

He said he's only running 10psi and driving to and from work, I dont think this is a high risk situation...

Last thing you wan GTAAAH is to go out and get into more debt when your not ready mate.

My 2 cents (Flame suit is on)

[GTAAAH]

haha, i just found out citybank will take on my loan for 7% less interest PA than commonwealth, so the money i'll save will pay for the turbo (eventually) + then everythings new and i can stop driving it like i'm scared it'll blow up all the time.. + dad's loan service is 4% PA so no hurry there

[Imtorqing]

Also.....What oil are you using as I didn't see that posted anywhere.............

I was using valvoline run in oil on mine.......500k service, 1000k service up then 1500k then 5000k I think....then started using the good stuff.....Also I wasn't allowed to use more than 5psi by my engine builder until it was run in.
