Burning Smell On Higher Boost On Full Throttle

[R33Turbo]

Hey guys again,

im running 11 psi boost (High) with only cat back exhaust and pod filter with NO FMIC...

Whenever i switch it to high boost (11psi) and go full throttle i can usually smell something like burning coming from under the bonnet area (can usually smell it as the window is open)...Just wondering if this means im destroying the turbo whenever i smell this or its just normal for such heat without FMIC (as i understand SMIC on GTT R34 is alright for under 200kwrw, as im running 178kwrw)...

You guys are a great help by the way, so i'd like to take your advice on this as well.

Thanks again

Does anyone else have this smell when gunning the rocket GTT R34 ? with higher than stock boost?

Im not destroying the turbo am i? its just wearing like a turbo usually wears with full throttle right?

i had this prob with my rb20 years ago, it was the gasket on the cam cover on the exhaust side, and on WOT applications the oil would leak past the seal and onto the hot manifold.

5 bucks for another gasket and all was good.

not saying thats what your prob is, but it could be something to look at, what kind of smell is it?

[R33Turbo]

its kinda like oil heat smell yer...i was guessing it might be but it did the same on my R33 too...wats the coincidence of 2 of the cars leaking oil, but it seems to only do it on higher boost so i was thinking maybe its just the smell of the heat on higher boost?

[Simon-S14]

just higher engine rpm is forcing the oil out past the cracked seals on the cam covers... quick wa yo see is if you jhave a look at the exhaust cam cover, and down the side, is it covered in crud and oil oil? if it is you've got a leak.

Well the head gasket used to leak with oil cuz it wasn't tighten down properly but now that it has been tighten down....

Its not much of a problem is it if its leaking? i may as well live with it?

no mate the cam cover ontop of the engine..... not the head gasket besides if u think head gasket is below the manifold so it wouldnt run onto it would it

First I would give that engine a real good degrease as you will never find oil leaks with old oil stains.But be very careful spraying water in the coilpack region and also try not to spray degreaser onto the pulleys themselves.I had one seize on me from overzealous degreasing.Once you got that motor and suspect areas spotless then you can start to study the real nature of the problem

Thats got my vote aswell. I get the same thing when driving hard, and also extended drives down the motorway. changing it when i do my 100K service. Hiping thats the prob.

i've got the same smell, and i know my passenger side cam cover gasket is weaping. makes sense that it would get worse at WOT.

but i never had the smell until i did my 3 inch dump, and raised the boost to 12psi from 10psi. maybe the leak is just getting worse, or maybe the higher boost makes it leak more?

one way to find out i guess. how much are these gaskets? where's the easiest place to get one?

[MBS206]

I have issues of blow by (MAJORLY BAD blow by) at the moment, and it causes this smell dramatically.

If it's an oil issue, track it down, fix it.

Everytime you smell it, you're burning oil from some where.

It might just be that a gasket has gone, or, with an increase in exhaust flow and higher boost, you have more blow by, and a catch can could fix it.

ive had same causes with my car but i always thought nothing much of it, and sorry to ask a newb question but where do i check? wheres the cam cover? wheres the manifold?

[10MinuteCar]

so wheres the cam cover? where should i be looking at for oil leaks? can i get fotos and more basic description rather than terms?

[GeeTR]

Lol@ 10minuteCar

R33Turbo - Instead of the smell being derived directly from boost, i would say its just from the increased heat when on 11psi and WOT.

As mentioned, after market systems can cause non factory heating of area's. (In your case its oil, could be plastic, rubber smell etc)

Clean it up, and look for leaks, you might need to have a think about some under bonnet heat management

[10MinuteCar]

was being serious ya know?

[Simon-S14]

lol

cam covers cover the cams... who woulda thought they are the two covers on top of the motor, the drivers side on has the oil filler hole in it, it is usually the exhaust side (passenger) that leaks onto the exhaust manifold, the exhaust manifold bolts to the head.

if you want pics, do some googling.

[10MinuteCar]

exhaust manifold is the passenger side where some sorta rectangular shape bolts onto something (head) right?

and are the cam covers underneath the neo cover for my r34?

do you need to use gasket goo when changing cam cover gasket?

[Simon-S14]

no

just clean all surfaces
