Car Problems!

[rad100]

ok ppl heres my problem!!!

the car got defected in early jan! it has been sitting around whilst work has been done on fitting turbo, cat and service! i got the car home last week and it was blowing a small amount of smoke (grey/blue)on idle and driving. this would get worse with abit of acceleration! i thought oh yeh its coz its been sitting around for a while... i have been turning it on and driving it around the block on an average of 20mins per day and the smoke today has been a little worse! when accelerating to boost (7psi) it dumps smoke! blackish with some grey... thats wat i saw form the rev mirror. i do believe that the oil was abit too high when the mechanic started doin the work..

so would this be due to it burning the oil that was too high?

the turbo stuffed?

running too rich/lean?

or just burning too much oil all together?

also whats the go with regency and exhaust smoke? and can i get a fine?

if anyone has some suggestions? as i havent got much of a clue! would be great....

thanks ppl much appreciated..

If the smoke is blackish is fine is just fuel, but it should only happen under hard acceleration, not at idle.

Check your cooler piping for oil deposits.

Hmmmm, I've way over filled my Rb20 with oil (full 5 litres) and no problems at all (so far). Turbo seal could be gone or piston rings are fried. My bro had same thing with bluish smoke and it was piston rings. If so, start looking for a new engine. Do a comp test.

[rad100]

if it is piston rings could i get forged pistons to replace?

i agree with ^^^

firstly, get a compression test (gives you an good indication of whats the go) and from there decide what you want to do...engine rebuild, forged pistons etc...

goodluck mate!

build the crap outta the motor, itll be the best thing u do to it for future mods...

[SOOKIE]

I'd disagree with getting an engine rebuild, my brother has just gone through one on his Rb25, 6k and 1 year later to get car on the road. Just get a new engine, thats why R32 are best, cos of cheap parts. Remember, there is a lot to getting a forged engine, ie: metal head gaskets, balancing etc.

However, if you do decide to rebuild, go RB24 with GTR pistons and crank. They're usually pretty cheap and will produce heaps more torque and wont have to worry about regency issues if you went Rb25 instead.

Id agree with the RB24.

but i made a thread about this and have had personal issues with doing it.

I woul not go RB24 unless it was professionialy built and done properly. Huddy on here has one and he has just got it going strong now. And he has had it for a while now.

Find a 2nd hand engine. Make sure you understand that it's 2nd Hand. SO things will need to be replaced.

Good luck with it.

If u want to do the RB24 engine i have a bare block with head out the abck u can take away for free. I have no use with it. SPun big end bearing but these will need to be replaced for full forged engine anyway.

Good luck with it mate.

Far out man your bro got ripped then.....and what dont you think building a rb24 wont be expensive as f**k.

[rad100]

ok so if its pistons... would putting forged pistons in fix it? and would that be cheaper then second hand engine? could i get second hand pistons form and rb20det?

[SOOKIE]

sinista: I said that he shouldn't rebuild, but if he choses to, its not worth it unless you go for RB24. Yes, it will be expensive but probably worth it

Its not as simple as just getting forged pistons. My guess, you'd be up for 3k minimum to get a rebuild, and thats probably a stock rebuild. You'll need all new gaskets, tensioners, pistions and rings and may need extra work if the cylinders are scratched. You also might as well get new bottom end bearings, water pump etc. etc. If your engine is gone, find a clean second hand one unless your willing to bite the bullet and pay some big bucks

[rad100]

ok i guess ill need to get a compression test! this will show where the problems r???? oh and whats the deal with regency and exhaust smoke?

its just wierd that one day it was 100% fine then its blowing smoke!

like before my old turbo decide to go and smoke up the whole street it was blowing 0 smoke but now i have new one its blowing.. could the blow of the other turbo have something to do with it?

cheers for all ur help guys! its just been a long road since defect and its still goin!

[sinistaGTR]

the advantage if it comes down too it aswell, if you rebuild you know the history of the engine. thats a hurdle we came across with my missus rex, to buy another engine or rebuild, it worked out cheaper for us to rebuild it.

heres a rough guide;

pistons 1100 delivered,

head gasket-440 (trust item i dont trust cometic there shit)

timing belt- 100

bearings- 140 (acl race items)

gasket kit- 300

idler and pulley tensioner - 100

machining-200

water pump- 40

and labour all depends on if you take the motor out or how well you know your mechainc, mine cost me 500 cash but thats cause im good mates with them

lol...u guys make me laugh a bit.

Start simple and have the turbo looked at first. It might just be an oil seal. If its not then get the compression check done.

An engine refresh should only cost around $1800 odd + bits (oil, filters, etc) but dont start thinking down this road till u do the simple things first.

Every time someone posts smoke from the motor theres 50 posts -"Oh noes, go for the forged 500rwkw rebuilds"

Skylines (and other cars in general) dont like sitting for a while either

[sinistaGTR]

yeh but whats more fun lol hmmmm 500rwkw

[rad100]

yeh im gonna do the simples! and if its the pistons ill go from there! but i was thinking if it is could i just get like pistons or block form another rb20 and just swap it? anyone know good workshops down west subs? the car does run realli well! but i do notice eboost flicks between -17 and -18 so its ubit up and down!? ne ways yeh ill get it checked!
