Hello chaps.
Started my cossie up today for the first time in 3 months, went for a short drive, came back, and left it to idle on the drive for a bit. I noticed that there was a bit of blue smoke coming from the exhaust as it was ticking over.

Now, the head was reconditioned last year, with new guides, stem seals, etc. And a new T34 Turbo was fitted at the same time. If you blip the throttle, it blows a bit more smoke.

What what usually cause this to happen? I was thinking turbo? but i dunno.

Cheers

would have said seals if doing it on idle, whats its like when driving?

Oil being burnt...

Gordon1

that will be your turbo then, who did the turbo ?

paceo

iTrader: (5)

yes blue smoke generally is, let us know what the problem is!

if its not been used for a while you may have a piston ring stuck letting oil past and burning off - get some heat into it, needs a good thrash to loosen probably

agree witha.k.a that happend to me car sat for a while and then when next used did the same as above....give it a good canning if it dont stop then you will need a re ring

boXXer

i know its burning oil....

And i did give it a bit of a hiding TBH. Hit 30psi a couple of times, and got up to temp before i went out...

It drives like normal aswell, doesnt miss or anything at all. Im also thinking turbo...

it was built by "CR Turbo's" i believe.

Does it puff on the downhill off throttle then on senario.

used to before i got the head done....

will try that tomorrow on the way to work.

mine used to get surrounded in a big blue cloud when left idleing for a couple of minutes. changed the turbo problem solved.

boXXer

OH YEY!

Topped the water up this morning, drove to work, and it used all the water. SO topped it up again, went for 20mile drive, and its emptied the header tank AGAIN! Noticed on idle, its also smoking white (like condensation, not smoke). Would it be using water cos of headgasket? Its not leaking it onto the floor, or anything like that, and doesnt use water when engine is off.

fun!

classic HG symptoms, thing was alright when it was first done when we were going to coomb though wasnt is ?

boXXer

yeah it was fine mate. Used to use a bit of water per trip anyway, but now its getting bad. im getting a tad pissed off with these cossies.

rsnissan

iTrader: (9)

yeah i know what you mean, i have spotted a few things now mine is in bits

boXXer

so am i going to be taking my head off AGAIN? thats 3 times in 3 years. Really pisses me off.

Chip

iTrader: (3)

Certainly sounds like headgasket

boXXer

yey!!!!! If thats gunna happen, i think im going to stick a GT30 on it. What ya reckon?

Chip

iTrader: (3)

Sounds like a plan

boXXer

do they bolt straight to 2wd manifolds? what else needs changing? apart from injectors.

Alan s1

Mines not been off the road in 3yrs

Sounds like i have'nt missed alot then lol

Whot injectors will you run with the GT30 if you go that way i would like to go bigger with mine as its not going to move from the garage for a little while yet so maybe able to afford a bigger turbo at some point

boXXer

Dunno tbh mate. siemens Blacks seem to be the way to go nowadays. But can you run them on L6's? Im not so clued up on the newer turbo/injector combos TBH.

Chip

iTrader: (3)

You need a remap to suit the bigger injectors, and yes the gt30 will bolt onto your manifold no problem if you get a smaller internally gated one

Alan s1

There whot i got in mine atm (o tho no chip atm but Stu will suplie them if you give him the details he need and post it to you )

Thats whot i was/am going to do when i get that far lol so i could easerly go bigger turbo

I was wondering whot power it will be happy @ using that set up (Blacks GT30 Chip)

Alan s1

Whot power would we be looking @ then Chip

boXXer

Yeah i would prefer an internally gated one, cant be fooked with all that external stuff. Do black run on normal Weber L's then? thought you might have neede a P8 or something.

Anyway, so what should i do first? take the head off and check to see if its broke? its only 10months old, lol. Although i have been giving it 32psi of death everytime i use it. oops.

Alan s1

Runs on all of the L's

rsnissan

iTrader: (9)

you will need head work anyway ideally for a GT 30.............

boXXer

and i take it that greys are all old hat now then?

Alan s1

rsnissan mines had some head work but have'nt a clue whot the numbers and letters mean lol there was wrighting on the head of the engine i brought i'll find the pic see if you or chip know whots been done and if its any good to use with the GT30

Mike i was going for Greys and then Jay and Stu pointed me towards the Blacks as they have a better spray patten

Chip

iTrader: (3)

Depends on which GT30 and what head spec you have.

If you are on a standard head, you are going to struggle to get a lot past 400 I suspect.

Talk to your chosen tuner Im afraid mate, I simply dont have enough experience of that specific combination to say with any certainty, but its a good way to be going to get to the 450bhp ballpark IMHO if you use a smaller GT30 and some mild headwork.

Alan s1

Can you read whot it says i can make out In 14.4 i think o tho i could be wrong ??

or theres this one ??


Sorry pic craps iver bright or dark

Alan s1

can you make out whots the numbers on my head are and mean in the above pic as i have'nt a clue

Chip

iTrader: (3)

Sorry mate, nothing there that means anything to me at all.

Every different person who does heads as their own ways of numbering things anyway, and besides the numbers on port sizes etc are nowhere near as important as port shape, thats what seperates a good head from a bad IME and is all about the talent of the guy doing it.

Alan s1

I see ummm may just go with a T38 to be on the safe side at least i'll have a nice 400 then when ever then maybe
