Very Very Worried My Fresh Engine Is Not Right

[Italiazr1]

i have an r32 with a pretty freshly built motor

only done 10,000 kms making decent power

i just had my gear box changed to the r33 box recently.

as i just got the car back it hasnt been running perfect since.

i must admit ive been thrashing it lately to try out the new box

but anyway it is missfiring at idle and low revs. also has a bit of blow bye??? but engine is new???

i looked into it a bit more to see what was wrong and i had notice lately that my oil gauge in my dash

was only reading 2kg/cm its usualy around the 4kg mark or more

so i checked oil and there is none???? how much does a car use up??

do you need to drain oil when a new gear box is installed? maybe mechanic forgot to put some back in??

i dont get it car was serviced 5000km ago... if there is no oil could that cause exessive blow bye???

and the missfire??

my car doesnt blow smoke or anything and i cant see any oil leaks apart from one where a hose is just loosely fitted

im so bloody worried now that ive caused damage to my engine...

please help

No engine oil at all ?Hmmmmm... or only a little bit left ? I would be getting a compression/Leakdown test performed ASAP. Top up the oil before you even attempt to start it. Sometimes cars with Forged pistons use a " little " amount of oil but not like the amount you are describing. Get the Compression test done .That will give you more info

[Italiazr1]

there was like no oil on the bottom of the dipstick once i cleaned it and put it back in for a few seconds and pulled it out again

and the engine was warm

[Italiazr1]

there isnt any discolor/milky colour under the cap either

it did always blow black smoke at full boost but that is normal im told isnt it?

[GTR-32U]

Not good. I would be very closely monitoring that dipstick. Check it at least once a week until you get the car to the mechanics. last thing you want is to starve the engine of oil, Spin a bearing and bang totally lunch your engine

[Italiazr1]

yeah i know.......

if there is a compression problem can that be fixed with out another rebuild?

[GTR-32U]

Well if there is a problem with the rings engine build is mandatory...Get that check done first so at least you know where you stand.

Hope for the best, plan for the worst

[Italiazr1]

how much blow by is normal?

[Italiazr1]

the thought makes me feel sick

if my engine is gone again im out of the performance car scene

as much as i love it i just cant handle the cost and problems

[GTR-32U]

Modifying cars can be a heartbreaking thing at the best of times. Worse case scenario and the engine is cactus. Get an import engine..RB20's are really not that expensive

[R.3.2.G.T.R]

hope you have topped up the oil since, get leakdown for peace of mind

[Italiazr1]

havent started the car yet i need to know what oil to put in?

[GTRsean]

New engine. You will get some oil comsumption in the first few thousand k's, due to rings bedding in etc, then they usually settle down.

Just gotta keep tabs on the oil level.

A 10w 40 oil should be okay to use or whatever the engine rebuilder suggests.

Gook luck with it.

get a longer dipstick... rb25 maybe

my recommendations

1) see a mechanic before playing

2) see a mechanic before playing

3) see the mechanic who did the engine build before playing

lastly check the oil level, any std 10w40 or 5w40 should be fine, the first digit identifies how long before the oil rushes to the head when you turn the key

so 5 or 10 is ok - wont be a massive difference. when the engine is warm at idle, oil pressure should be 2kg/cm2 on the standard pressure gauge

if you had no oil pressure guage would show 0 and engine would cease up guaranteed

idiot light would also be on so its unlikely there is NO oil in the engine, but low is possible (again less oil, means more pressure, which would show on the guage)

ie - you shouldnt have 5kgcm2 oil pressure at idle, and you shouldnt have 1kgcm2 at idle either (this is when engine warm)

RB30 dipstick + check oil when cold not warm.

and the engine was warm

it possibly sounds like another engine with the rings put on upside down as a 5000klm old engine should not still be using oil at that rate for the next 5000klm.

how often did you check the oil level?.

went to see the mechanic today he reckons it is fine and im streesing for nothing

i checked the oil often in the first 5000kms like every second day

it seemed fine not much oil consumption as far as i know

i had it serviced and ive done about 4500kms i thought there would be no way the oil would be low its only done 4500kms

i only checked it because the oil gauge was down to 2kg/cm2 its usually 4kg/cm2 when driving under load

so because of the missfire i had that was only at idle i started to look at it more

checked plugs to see if everything was connected ok and i took off the breather pipe

to my catch can and under bright light i can see the air particles coming out IS THIS NORMALl???

the catch can fills up with sorta like water not exactly oil.

mechanic said thats just condensation at startup when cold

told me its normal also

the filter also on the catch can soaks up with oil and if you touch it you can see its definately oil

[Italiazr1]

whats this about the dipstick????

should i get a longer one or is that some joke???

cause its not so funny when you just spent 15k on mostly the engine
