turbocharger for 3B toyota engine (3 Viewers)

[Diesel42]

Right, which is why I am not blaming you nor have I.

I'm merely relaying my experience.

This is not your fault. Absolutely mine in that I did not do my research and due diligence before just slapping something onto my truck. And the research I did was cursory, at the time.

I have and will continue recommending your kit to other 3B owners mainly because of the fact that it is domestic and supports a small company.

I understand, but what I really need to know is what's wrong with the kit that makes it inferior? Which components need to be upgraded or changed? I have always searched for higher grade items to include or change. You recommend the copper gaskets, but even before we changed those the others weren't a problem. The new ones were made from the same material that Boeing uses I found on some parts we were doing for them. They turned me onto their maker and I had them make our gaskets. Much more expensive yet I still ate the extra costs. So if the one inlet adapter is to large and causing turbo failure I need to know so I can investigate it. I don't doubt you had a problem but why then hasn't there been other complaints over the last 8 or so years since I developed the kit. I can only think of one guys some years back that had a similar problem. He contacted me I contacted Garrett who rebuilt his turbo for free. It has ran fine ever since. Maybe it was a bad turbo, absolutely can happen. But a 3B with high oil pressure blowing a turbo up I have never seen. So that the viewers here understand and my company can benefit, please advise me as to what is cheap or inferior to a $10,000 turbo system. I will change it.

I'd like to know what the tests are the diesel shop guys do who do this day in and day out recommend.

Diesel42, you need not change any of your gaskets of components. They are already more than adequate. You have designed a very nice kit.

I think the kit is fine and just needs some tweaking. Unfortunately, the tweaking is coming out of my pocket.

This is par for the course. Fact of that matter is that this kit is just a guy in his shop putting things together based on one 3B engine in a BJ42. The results, in my opinion, are going to vary greatly based on the end user's due diligence to understand turbo's, how they work, how they might work on your truck and in the end, how much work you are going to do to your truck to prepare it to accept a turbo.

This is not a kit from say Turbonetics or any of the other big turbo players in the professional tuner/turbo market. We look like amateurs to them and cheapskates-- and the LC market has historically been both. Go and see some of the turbo setups on Supra's or big diesel trucks. These guys are spending $10K + easily.

It sort of is what it is and that's the long and the short of it.

Not to add salt to the wound but I have to disagree with a portion of the above statement. I have not spent anywhere near 10K+ to have professional installations of Garrett turbos and to date they have performed flawlessly.

Me too.

I'm the guy who sized that garrett turbo for that kit. A job I haven't seen a dollar for too.

I was being hyperbolic Charles.

Interesting. Good to know. That's not what I was told.

"Hyperbolic" .... Isn't that where an airplane exceeds the speed of sound?

 

[OGBeno]

Anyway, I'm not going to spend anymore time discussing this since I can easily see this going to go down the tubes quick since there is blood being smelled.

The kit is great. Hundreds of people use it worldwide and my situation is most certainly an anomaly/user error. I will modify my commentary to reflect.

Back to regularly scheduled programs then.

IP when it got back from shop:

Turbo after rebuild:

IP installed:

Upgrading the fan and fan clutch and then turbo install.

Hope to work through the night and go for a drive tomorrow AM.

How did it work out? What did your engine tests show?

 

[emoto]

I'd like to see what kind of crank case pressure is there and why the pressure in there would affect oil seals in the turbo. You have exhaust pressure and heat turning the turbo and then the suction and pressure built up on the other side to help air in. Noobie trying to understand turbos. The blow by pushes past the rings into the crank case, then the compression isn't as good. Does this affect the exhaust pressure then because exhaust is lost past the rings affecting the exiting gases into the turbo? Crazy, kinda like preload and after load in the human heart.

Oh, and isn't that TJ's vintage ale grande!! Gotta keep it to just one if doing delicate work..

Turbo oil seals are like piston rings. They always leak. They rely on the turbo having more pressure in the turbine and compressor housings so the leaking always happens inwards and pushes turbo oil into and down the drain tube.

If engine crankcase pressure gets higher than the turbine or compressor housings then they start to leak the other way, pushing oil out to the compressor and turbines. Making lots of blue exhaust smoke and feeding your engine oil via the intake.

I'm happy with my progress.

I installed the parts and did what I needed to do based on the 3B I had in my situation.

Again, I am saying @Diesel42 kit is great and EVERY THING TO DO WITH MY SITUATION WAS BECAUSE I AM STUPID: I AM JUST A STUPID PARTS GUY;

And the folks I talked to were very honest with me about 30 yr old engines: fix everything before tossing a turbo on it.... everything.....caveat emptor.

Be well.

 

[Owyhee Jackass]

The turbo technician has requested to talk to me about the turbo. Interesting. See what he says.

Is this all the technician had to say?

Nice Beno, I'm glad to hear it's working out. What did you address on your engine to avoid this from happening again? After going through all these posts folks will be looking for the solution to your problem. Would be a big help.

I agree. Sharing lessonsome learned is key to moving all of us forward

Totally get it. Drain tube to crankcase. Thank you Dougal.
