I am sure there have been plenty of people that have had a failure from some debris in the oil clogging their oil restrictors and causing the bearings inside the turbo to fail, just happened to me today on a 4th gear 22psi pull down the highway. Car boosted like it always did but I heard a sound that might of been a ping so I backed out of it and pulled into a school to check my datalog, when I was leaving the lot the car acted just like I had blown a coupler or had a huge leak in the charge pipe somewhere. I got home and found no leaks and when I pulled my CAI off the turbo and went to spin the wheel it it was like the bearings exploded as it was just all metal to metal, turbo is a Ball Bearing T3/T67 HO (PT6776RS) and it only had about 3k on it, all from the last month and a half. Took everything apart and found a 3/4 long piece of black RTV completely blocking the restrictor. This was a last minute thing I did when I was putting everything together after I had to remove the feed to install my -12 catch can lines, I just used the RTV in one spot as a last minute thing due to my friend had my HondaBond and it was a $1200 fatal mistake. I will now be feeding my new turbo with a sandwich adaptor and I might even add an inline filter for peace of mind.

Cliff Notes:

1. Dont use RTV (especially too much and or around your oil feed)

Piece of Devil RTV


I am actually not very upset that this happened, the car has nothing in the way of safety done to it, I have a cage kit that needs to be welded in and the car needs to be painted, so now I can try to get the rest of the car caught up, also a good time to get some cams and I will probably go divided T4 this time, possibly a S366-S370 and 4" back.

Ouch!, more reasons why doing things last minute is risky. GL with a replacement, I'm pretty sure you'll get a bigger and better turbo. Sometimes good things come out from bad situations.

 

I'm not sure why you used rtv at all, but then you got it on more than the threads. That's the problem, not where you got your oil source for the turbo from.

The title should be changed to "I sent rtv through my turbo, and it doesn't work".

 

So are sandwich adapters preferable as the OP seems to be saying, or are they just fine to use (but not preferable), or are they not so fine to use for some reason?

Anyone tried on of the ones from glowshift?

 

damn ben that is teh suck.

Going to have to agree here. Why were you using RTV as a thread sealan, period??

 

Yeah its not where you were getting your oil from. It didn't have any issues until you decided to use rtv.

 

Cheers for the warning, just getting round to doing this, will now run from sandwich plate!!!

 

Install error. It wasn't like a piece of dirt from the engine oil got stuck in the restrictor. It was from you.
I feel comfortable using the oil pressure sensor hole as a feed for the turbo.

 

Have any of you ever checked that oil passage? It's filtered oil....

 

Classic!

I was told repeatedly its unfiltered in the past..........

I used Sealent because the guy that used this block before me threaded in an incorrect thread into the feed and the kit that I had went in loose due to the damaged threads, if I didnt use sealent it would of leaked

I used the RTV from the initial startup of the setup, not like I just used the **** yesterday and it came loose today, the motor has been running for over 6 months.

 

If your feeding from the oil pressure sensor hole its filtered oil.

The only filtered sandwich plate that I can think of is from GE.

 

all oil in you motor is filtered at one point or another guys, if you want 100% to be sure oil is exiting a filter and going straight to the turbo run an inline filter for the turbo oil inlet line.

Or just drill and tap the oil filter

lol

 

If crap is in the crank case upon assembly or gets in via dipstick hole, breather, etc, if resides in the oil pan until the pickup sucks it in. Until it hits the filter, the oil is only as clean as your oil pan.

Sandwich adapters have to be made to tap into the center hole of the filter section. It goes from the outside, through the filter, then into the center threaded hole.

Personally I use the oem sensor hole, except its all rigid using 3/8" copper. Zero flexing forces on my threads.

 

congrats to you for not blaming every company that you bought parts of of .....not every day that some one looks at there own stuff first

 

Sorry bout ur misfortune, hope everything works out for the best

I think the people that told everyone that the oil from the oil pressure sender is not filtered are the people who made the oil sandwich adapter

I personally never had any problem with getting oil anywhere in the block. Maybe I got lucky

You said you had to put RTV on the thread to get a good seal because the threads were partially stripped. That RTV was right at the entrance to the oil feed line. That's what allowed it to get into the line, to the oil restrictor and clog it. If you RTVed the a feed line from a sandwhich plate you would have the same result. I'm sorry to hear about your turbo , but it wasn't your feed location that caused the problem.

Thanks for your explanation, until now I had absolutely NO idea how this happened ........ try reading
