Here are my specs

94 gs-r with a 10 bore and type-r pistons, bullfrog intake cam, stock exhaust cam, and a milled head .010

My car was recently rebuilt by me, when i first started it up it was idling at 2000 rpm and never dropped back down and after 900 miles i'm seeing smoke and it smells like ****. I took it to the shop and it threw off a few codes, one being the distributor, and i forgot the rest, but i replaced the distributor and that code was gone, but my idle was still the same, they put a new ecu in and it started up at 750 rpm, but they couldn't sell that ecu, so i just drove with my fucked up one. sometimes the car hesitates at full load around 7000 rpms, any information will be helpful

 

it also uses about a quart of oil every 4 or 5 days, but i also have a leaky oil pan. the coolant levels are consistent.

 

is it blue smoke?

compression test?

what is your experience with building engines?

quart every 4 or 5 days is excessive

 

Start with fixing the oil pan leak!

 

it looks like white smoke, but i'm not using coolant, this is my first build-up, everything is new and all gaskets including piston and piston rings are new from the dealership, and i'm fixing the oil leak saturday and readjusting my valves

 

but your using water right?
white smoke = steam

this is your first build, did you check the piston to wall gap? check the ring gap?
did you hone the block correctly?

 

hey whats up kyle, this is luke the guy that let you try his ecu. been looking for you at the shop but haven't heard from ya, too bad to hear about the smoking, hope it is nothing major

 

I hope you didn't use synthetic oil to break the rebuild in.

I thought that was a myth, any professional mechanics care to comment on it?

 

after 946miles....and then ur see the sympton...rebuild engine needs to get broken in properly...did you abuse it while in breakin in period?

H-gasket leak, rings leak...INTERNAL BLEEDING

if oil pan does't leak...then ur got internal leak...most likely will be rings...soem say white smoke=steam, true...but can also be from oil...WELL HOPE THIS HELP

1qt a day? ur car drinks oil more than i drink water man

 

that's bad, man
I rebuilt my 96 GSR and it was smoking for a little bit but wasn't using any oil.
Throwing some decarbonizer in the intake manifold blew out the little bits of carbon
that was left in the head. That's an excessive amount of oil to be burning.
Do the compression test and the you'll know.
Btw, did you use the GSR intake manifold? I'd check the throttle cable and
then maybe the vaccuum hoses.

 

Im a 3rd year apprentice and yes its is true that you shoudl use a standard mineral oil during brake in period on a new engie because synthetics do to good of a job with coating that you eng up driving the car, thinking its broken in and then driving it hard and damaging it.
You say you drove the car past 7k rpm and you only put less than 1000k on the car. VERY bad idea, especialy with the setup you are running. The pistons and rings you are using are to small for the bore of the cylinder as far as i can tell. So you are experancing a killing blow bye that is probably causing the hesitation past 7krpm. And also will contribute highly to the use of the oil. As well, you rebuilt the motor but left it leaking oil. VERY bad idea, if a new motor is starved for oil in anyway it will kill utself in no time. I always recoment to my customers that an aftermarket oil pressure guage be hooked up in the car to monitor the oil pressure just in case of some problems.
And the white smoke can be from a couple things, condensation in the oil pan which is pushed past the rings and emmited as white smoke. Or a blown head gasket. To me it sounds like it has a blown head gasket. So you are going to need to rip off the head and have a look just to make sure otherwise risk killing the rebuilt morot if not already dead.

Also, the 2krpm warm up was REALLY bad on a brand new engine, unless you primed the oil pump to begine with. Because the top end of the engine woudl have been starved for oil for a period of time. Possibly long enough to warp the head and cause a minor head gasket leak. Try re-tourquing the head bolts and see what happens.
But for your next rebuild make sure to deck the head and block, prime the oil pump, keep the rpms low for atleast 3k, mad after the first hundred miles change the oil filter and oil, cut the filter open and inspect for metal filings.

 

i did use synthetic oil, but i witched back to regular, and i also put 500 very easy miles on it to break in the rings , well i'll find out this weekend about the head gasket, wish me luck have a good weekend guys, thank you for your help

there is where your problem is.

when i seated my rings i put it on the dyno and strated making wot throttle pulls, starting at 2000-5000 the gradually increasing my rpm with each pull. the car smoked a little the first few pulls but cleaned up before i took it off the dyno

the window of time you have to cut your rings in and the way you do it is critical, if you never get it to wide open throttle with a load you don't pull alot of crankcase vaccum, crankcase vaccum pulls your rings against your cylinder walls to help cut the ring to the exact shape of the cylinder
