hope this can help sum ppl with trying 2 diagnose my car

Its dead easy to diagnose and you've been told a few times in this thread. Get a compression test done. Any mechanic can do it.

If your compression is down your engine is stuffed. Then you get a leakdown test to work out if its the pistons and rings or if its the head. Then you start saving.

If the compression is OK its almost certainly your turbo, get it taken off and inspected by someone who knows turbos.

But don't keep asking for help and then ignoring when ppl give you the right answer.

[BBQ]

From a very similar experience, Number 6 Cylinder, ring lands are on their way out.. It will only be a matter of time until you put a hole through the piston its self and then its a new set of pistons job....

If you do a compression test it will still have compression in the cylinder, but may be a little less then the others. It will be number 6 cylinder that will go first. So see if you can do a check on it, but it will eventually get worse depending on, If you bring it on boost a lot.

[BBQ]

Just out of curiosity how much boost were you running ?

[R33_KRAZY]

thanx ppl's....

ohh an im not inoring ne1 if i was inoring u then would i be busy at the moment trying 2 find a mechanic 2 do these test 4 me asap..??? neway thanx 4 the advice........BBQ so wat u r saying is even if it is the ringlands on 6 an i get that fixed then sooner or l8r that no.6 is gonna go neway..????

[BBQ]

Yes, To be able to fix it you need a new set of pistons. - I would advise you to not Drive the car hard but to babay it, because it will score the cylinder and you will need to spend more on machining cost when you have to re-bore it out and fit the new pistons.

[cameron]

Just out of curiosity how much boost were you running ?

10psi

[cameron]

does the smoke smell like burnt oil ?

check your dip stick, to see how much oil is in your engine because if you drive it its going to chew alot and you'll have to keep putting some more in their.

[R33_KRAZY]

yeah it does smell like burnt oil...an nah im jus straight out not drivin it doesnt look like she is healthy n i luv me line 2 much 2 break her even more

[R33_KRAZY]

hey can ne1 tell me what an aproximate price will be 2 get a decent set of forgies an get them put in....TOTAL COST......

[cameron]

Read my signature ,

Give *stick* a call.

Tell him that your after some forged pistons etc

[R33_KRAZY]

thanx man...

COSTS INVOLVED IN A REBUILD:

---------------------------------------------------------------------

Remove and Replace engine - $1500

Labour to strip down and rebuild motor - $1500-2000

Head service - $600

Miscellaneous gaskets, oils, etc etc - $500

---------------------------------------------------------------------

Forged pistons - $900 -> $3000

It should cost anywhere from about $4000 upwards to do a proper engine rebuild, not including any upgraded parts like forged pistons, rod bolts, etc etc... Add those to the rebuild cost.

[LOW25T]

maby consider buying a new motor, you'd be looking at around $2000 for a decent one...

[R33_KRAZY]

yeah i reakon.....$4000 for rebuild an say $1500 for decent set of forgies...might as well get a RB26dett....... hehe that could be good

[vspecv]

yep she is knackered, dont even bother with the turbo, i have rebuilt half a dozen rb25s that so called reputable workshops diagnosed as a crook turbo.

hey merli do u get a barrister to work on your cars, $1500 to remove refit a gtst engine, less than half that.

[Merli]

She's only a lowly paralegal, but she's got GREAT legs

Does it cost a lot more to R&R an RB26? They're the prices I'm working off that I was quoted from 3 workshops here in Sydney to R&R my RB26... I wouldn't have thought an RB25 would be that different?

[vspecv]

rb25 and rb26 are worlds apart in labour hours.

to remove and refit a gtst is around 6-7 hours, rb26 is closer to 20
