sr20det smoking HELP!!!

[lucas240sx]

My sr is completely rebuilt
Stock ecu and smic
CA pistons, manely rods, acl bearings, crank polished,(crank, piston and rod balanced together), bc spring and retainer, shims checked installed correctly, everything torqued correctly, apexi head gasket, arp head studs, reinstalled t25 that hasn't been ran for over 4 years

One ecu didn't allow 3 of the plugs to spark so I switched to another and motor started right up, but not smooth
Cams and crank aligned and timed right with cas
The motor smokes white the whole time

I Rev the motor and I'm not hearing the spooling or blow off(smic)
The plugs are black right away...running rich?
It backs fire when I Rev also

I'll try to upload a video

does your oil smell like fuel?

[lucas240sx]

Idk
I'm going to the shop tmrw to check on it

What if it does smell like fuel?

Also going to swap cluster with a other dohc and subharness
my temp.and tach not working

[lucas240sx]

Was also thinking possibly my turbo is bad?
I have another t25 and t28
Just don't want to struggle in replacing it as I've been waiting 3 years for this

[lucas240sx]

The stock.hot pipe is not hot at all while the exhaust manifold it very hot
The hot pipe feels like all the other pipes

[blksylv]

If it smells like fuel, it could be an faulty injector or injector o-ring.

[lucas240sx]

Injectors were cleaned and flow tested with new o rings
So that shouldn't be a problem

[silspeed]

Swap out your MAF and see what happens

[lucas240sx]

Yea I have question on that....I unplug it and still runs the same
I don't have another maf but a friend does
Well I tried a ka (I think they were dohc which I know I need sohc) and the car wouldn't start

[slidins13s]

If you unplug the MAF and it still runs fine then you need a new MAF.

[lucas240sx]

Ok
I have friend who will.be bringing over his ecu, igniter, and maf

What would cause the motor to smoke?
I really hope my turbo isn't bad

[silspeed]

I had this issue when driving in extremely wet conditions. It was so bad one time I had a tow to a shop and they said they'd check it out the next day. When they got to it; it ran fine no issues . I chalked it up to a wet MAF. But I would imagine whatever happened to it (the MAF) could happen wet or dry.

[silspeed]

What slidins13 said. Your engine should run horribly on the verge of stalling or even stall when your MAF is unplugged. Check your wiring of the MAF too and make sure all that's good.

[lucas240sx]

I will double check the wiring

[bansheeracer2003]

Does the smoke smell like oil?
What color is it?

[silspeed]

^ this. If your oil smells like fuel DO NOT run it until you change your oil! If there's fuel in the oil you could wipe your bearings out.

[lucas240sx]

I will check the smell
At the time the oil still looked brand new

[Vegass13]

if the smoke is thick white it's burning coolant (most likely head gasket keep an eye on coolant overflow level) if its blueish or grey it's probably burning oil so keep checking oil level

[lucas240sx]

It's very light white smoke
Just seemed like a lot since the car is in the shop
BTW last week was my first time starting this motor

[lucas240sx]

I went to check on it
I had opened the valve cover lid and could smell gas

When I first tried to start the car with the bad ecu I'm sure I flooded the cylinders and since the rings are seated fuel worked it's way into the oil?

I will pick up some oil and replace it tmrw

[lucas240sx]

I also can't get the tach and temp to work
I have tried 2 dohc and 2 sohc clusters and nothing
I have the 6 wires plugged in and nothing

The car is a 89

Are you really 28? You can not, type words that make a statement and add a question mark at the end?

Pull codes from your ecu, replace your oil and filter. Before you turn the ignition on, check the injectors for leaks. You want your bov to make noise while your engine runs like shit, prioritize!
Your cluster probably doesnt work because of the dash connector?
Pick a problem stick with it until it's fixed.
Also do some reading, you might learn how to troubleshoot that way.

[lucas240sx]

Thank you for the grammar tip! I'll be sure to take your advice when I'm writing and essay for you.

I don't understand you statement about wanting my bov to make noise while my engine runs like shit.
The dash plug to the ecu is connected correctly with the 6 corresponding wires

I've been searching on Google everyday for each problem
It's never stated how they fixed their problem
I'm going to double check the trans harness to fuse box and the temp senors plugged in correctly

[lucas240sx]

Still haven't figured out why the motor is smoking
Changed oil and plugs
I think my maf is bad
Still don't know why the cluster gauges aren't working

[Vegass13]

did the gauges work at any point before the built motor went in? or was the car never running until this motor?

also have you made sure the coolant level hasnt gone down?

[lucas240sx]

I bought the car as a shell
Tach and coolant has never worked
I've checked over the wires and everything lines up

[Vegass13]

Well rpms don't work on SOHC with sr, but I would disconnect the clip you had to solder the wires for and test the pinout for power and test the wires going to the temp sensor. Either that or try putting in a new temp sensor if you haven't already..

[lucas240sx]

Brand new temp sensor
I've tried 4 clusters
2 sohc and 2 dohc
Gas is the only thing that works

I'll check the wires for power

[Vegass13]

Ya I would think the only thing after that would be a diff ecu

[lucas240sx]

I tried a friends maf.....found out mines bad
Turbo is good
There is oil residue on top of each pistons but my BKR6E plugs still look good

Tried his space cluster and all the gauges worked
After a while it started to smoke behind the cluster then it died
Turned engine of and back on
Cluster lights come up but tach and coolant stopped working

[Vegass13]

Better take the dash out and find out which wires are shorting and if the wire insulation burned up...then tape the seperately so they don't touch any wires or metal
