Ok, quick question about oil levels as they pertain to sufficiency.

I have a slight oil drip, as mentioned between filter and adapter, not block. Therefore, I periodically add oil.

* Should I be checking the oil levels on a cold, or hot engine, or does it matter?

My oil level according to dipstick is either at second dot, or just above usually.

* How much oil does the turbo hold, and does this oil leak out when the car is off, or does it stay primed?

* To sufficiently feed the turbo, should I keep my oil level just above the second dot, or can I let it get as low as midway between first and second dots?

Even though these questions may seem simple, I would prefer a concrete answer as I do not want to damage my turbo at all, and keep it in its prime function.

Thank you!

You should fix the leak


You check the oil when the engine is cold.

I not 100% sure, but I heard u should warm ur engine before spooling ur turbo.

As far as oil level, if its between the 2 dots, u shud be okay. Just dont let it get below the bottom. The difference between the bottom dot and first is only 1 qrt of oil. But since ur turbo, u really should be anal about it and keep it full, I wouldn't go over since ur engine is running a larger load now.


I wanna see a video of u ripping that ****, did u get it tuned? I wanna hear the turbo whistle through the exhaust.

Thanks for your info Abdi. It's not tuned yet, probably next week it will be. I know I should fix the oil leak (duh ).

I'd like some more input from other members to add to/confirm my previous question (and Abdi's answers).


Other questions arise:

I just drove to Borders to study for a few hours. On the way there and back, I tried to engage VTEC, but I couldn't. Prior to turbo, I had wired in a VTEC indicator light according to the 6GA DIY. Now, it does not engage at the RPMs it usually did before the turbo. Now, I am using a P28 chipped VTEC ECU, and OBD2B to OBD1 conversion harness.

* Why could the VTEC be disabled?

-> Could it be that I broke my VTEC solenoid, and it's like a DX model now (with boost lol)?

-> Could it be that the OBD1 conversion somehow disengaged the VTEC and I need to repin it?

NOTE: There is no CEL present and engine purrs perfectly.

After searching 6GA, I found a post from long ago:

There is no performance and econ VTEC for us. It's all economy. Period.

VTEC = RPM + Throttle position + Oil pressure.

Could my problem be that I'm low on oil pressure and VTEC doesn't turn on? Car runs well though..


Another theory from an old post:

My guess is that when you installed the vtec indicator light, you messed up the selenoid that triggers vtec, and so basically your vtec light, which is meant to show you when vtec engages, is actually stopping it from engaging.

Could this be happening? It worked fine before the OBD1 conversion, but could this be the issue now that I am using a different ECU and running a harness?


Any input, would be appreciated, as I am not sure what's going on. It's not causing an immediate problem, but when I get tuned, I'd like to have VTEC working .

Thank you!

The feed lines should retain oil. Of course when you start your car, you should always wait like 4 seconds before you rev it so oil pressure can be built to a good level. You shouldnt worry about priming the turbo every time.

remember the oil pan stores extra oil. Your engine should pumping the same amout of oil at the same pressure if your at the first dot or the second dot. Just try to keep it above the low dot.

as far as your vtec. I would just double check your wiring. Its probably be because of lower oil pressure because of your leak. Because your leak is after the oil pump, Its bleeding off some of the pressure unlike an oil pan gasket leak, or a valve cover leak. Just drive your car smoothly till you get the leak fixed.

Thanks for your input Nate!

I'll have to drive it carefully, and will probably buy that oil feed line & tee from you soon, as I need to have this leak fixed ASAP!

I'm glad I could get confirmation on the oil level, as I was worried every time I saw a few drops.

The only wiring I did was resistor box, injector clips, and 2-wire IACV clip. I'm sure you're right and it's just low oil pressure not letting the VTEC engage.

That's another thing I'll have to do quickly, is buy an oil pressure gauge, that will tell me for sure.

I guess I'm going to roll easy with it for now, and take it to the tuner today just so he can look at it before the tune and maybe let me know/confirm/suggest what I should fix and take care of before we give it some throttle on the dyno!

Hey Nikita, I doubt your VTEC isn't engaging because of oil pressure. Check the wiring cause in my experience the car reacts totally different when 1. there's not enough oil for VTEC engagement and , 2. there's a wiring issue with the solenoid/ecu.

1. If you have low oil/oil pressure the car would feel like it's redlining around 3 - 3.5K, and you wouldn't have any throttle above.

I have a few snapped bolts on my head that hold the valve cover down so i occasionally lose oil from the gasket and it gets low to the point that vtec won't engage cause of low oil.

2. If vtec simply wasn't wire for or something wiring related is keeping vtec from engaging it would just feel like you were driving a dx. The entire RPM range would be available yet vtec just will be absent.

When i did my 5spd swap, before i wired for vtec, it felt like this.

Thanks man! Yeah I think that wiring may be the issue here, or solenoid.

Re: Russianred's Turbo Build Thread [ 56k = ok.. for now ]

ROFLMAO! I hope this will be the case...

I just called Xenocron, and Chris told me that he set the VTEC to engage at 4600RPM.. That may be the problem right there, is that I simply have not even revved the car high enough to engage it hahaha!!

I'm going to go out now and give it a good rev (in vacuum).

Re: Russianred's Turbo Build Thread [ 56k = ok.. for now ]

did you dyno yet? cuz i can't wait to see what numbers ur gonna put out and some action videos

 

[Russianred]

Re: Russianred's Turbo Build Thread [ 56k = ok.. for now ]

I did not dyno yet man, I'll definitely let everyone know when I'm going to dyno and tune it, don't worry .

Ok.. so I took it out on a spin, and apparently I can't even rev it higher than 3900 RPM, therefore thecnically not being able to reach VTEC the way its set.

I called Xenocron again, and Chris said to try the other basemap chip that he gave me with the ECU, just swap it in. So tonight I'm going to install the FPR, try buying a new oil filter to fix the leak, and install the other ECU chip - perhaps the basemap on that one is a bit more suitable with my build. The chip I have now is fine, but I can't hit VTEC with it, and the other one is worth a try for sure! .

Re: Russianred's Turbo Build Thread [ 56k = ok.. for now ]

oh i see well will be waiting for it lol

but about your Vtec, so when you reach 3900rpms, it just stops and won't go higher, like if you have rev-limiter set?
maybe you have to change the map, or somewhere in options? lol
i don't know much about turbos, but just giving some ideas...

also if you go to dyno shop, don't they change the settings to ur ECU/MAP and will see that ur car doesn't go above 3900rpms and try to tweak it?
