Turbos Keep Seizing Rb26 Block Return Lines ?

[Hot33r8723]

My rear turbo keeps siezing do you think it could be a blocked return line or feed line by Any chance I'm saying it is but just wanna see what you guys think

[WMDC35]

prob more need to check the feed, check the line is clear for a kick off, is the motor sludgey inside?

[Hot33r8723]

Not sludgy at all motor is fine the turbo line is blocked

[Hot33r8723]

Thus allowing oil into the exhaust through pressure need to unblock So u think oil feed is blocked have U had this problem

so you're saying it is blocked? seen a few cars with turbo oil starvation problems, usually blocked lines/filters if it has them, it's getting oil in the exhaust after it seizes you mean?

[Hot33r8723]

Yeah I mean was running fine then the rear turbos exhaust wheel blew cos of shaft play it was hitting the inside of the turbo housing so I changed the turbo now it's make only 7 psi instea of 14 when I start it up only the front turbo spins freely at idle the rear one is hard to turn

[Hot33r8723]

The car keeps blowing Turbo exhaust wheels at idle the front one spins freely and the rear doesn't move now it's only boosting 7 not 14

[WMDC35]

the oil starvation will flog the turbo so the wheel will come into contact with the housing, if you disconnect the oil feed off the rear turbo and start it up you'll prob see no oil come out or the odd drop, you'll have to pull it apart and check and clean everything

[hypergear]

If oil feedline blocks then it will seize while drain blocks will cause turbo to leak oil from all seals. It looks like the feed is blocked. Check the line and drill out the oil restrictor in its fittings.

[Hot33r8723]

Ah yea definitely a blocked feed line no worrys feller cheers for the advice

[MagicMikeZ32]

Why would you drill out the restrictor? It's there for a reason, yes?

[hypergear]

Reason is when they do blow in middle of no where. You might have enough oil to drive your self out of trouble

[R31Nismoid]

wont be oil drain, its 4x the size of the feed.

feed will be blocked, meaning there is gunk elsewhere in the system most of the time... cause if there wasn't - how can it be blocked?

[Hot33r8723]

No I've got it all worked out if the turbo was seizing it wouldn't make boost its only making 0.6 bar so I'd say it's leaking somewhere one of the pipes meant to be 1 bar And now it's smoking like a bitch on boost I compression tested it and my results where this 50 55 75 100 100 125

[GTSBoy]

So the motor is stuffed.

[Tai1or Made]

compression tested it and my results where this 50 55 75 100 100 125

Lol.

Holy Sheeet!

Motor is le fecked!

Im sorry Ash, I've tried to stay out of this thread.

Your compression is wwwwwaaaaaayyyyyy f**ked.

Your motor has most likely sucked 1 of the 3 turbo's you have gone through.

You say you have it all figured out? I dont think you do. You need to go and buy another motor from the wreckers, this time you need to

• Make sure you have a good fuel pump
  
• Make sure you have working turbo's
  
• Make sure you compression test the motor prior to dropping it in
  
• Go and get a tune (for the love of god)
  
• Don't come on here and ask for advice then turn around and say NO I have it all worked out. (very frustrating when you offer advice and it gets thrown in your face!)

So you had the same problem back in July? Or is this a new compression problem?

If it's a NEW compression problem i would suggest

1. Getting a better tune

2. Learning how to drive

3. Selling the car all together

after reading some of your posts I have to ask, how exactly did you go about doing the comp test ?

you say the rear turbo is the one that keeps blowing but the front 3 cylinders have the lower comp
