Have a Nice Day? RS-T problem

First it was the link not connecting. I connected for about 5 minutes. I got around to setting up basic stuff, but not good enough. As I was doing stuff, the Radiator Fan word was flashing on the bottom right hand of the screen where the warning flags are. What did that mean? I also could see coolant coming out the exhaust but that should have been from overheating the motor 2 months ago. Then, the temperature started to rise, coolant still cold. I am suspecting temp sensor going bad. Any suggestions?

No, I am using a stock block with the ludespeed. I am really concerned if the turbo is leaking coolant from the seals or something of that nature.

Dude, I seriously think sometimes that the gods just dont want you to have a RS-T.

Dunno what to tell you. Start checking wiring and sensors I guess.

After doing some thinking with Jeremy on the phone, we came to conclusion that THE DAMN COOLANT SEALS LEAK. That's what probably caused me to overheat. I will go inspect/disassemble the turbo and look at what the oil/coolant assembly withholds.
Couple things:
A. Could the turbo that I bought from Ludespeed been rebuilt? And if yes, would you recommend Tom giving me a new one, since the turbo went frigen bad after less than 3 hours of use.
B. Would you recommend me just buying the center coolant/oil assembly or just get a whole new turbo?

That's all for now. I do suspect the turbo coolant seals, because the engine sounded very normal under idle, and not as if coolant has gotten into it. I will pull the oil and see if it is green on the bottom.
Anyone have a T3/T4B as a loaner?

Tom uses rebuilt turbos AFAIK. If its bad he will warrenty it. Just call him up and ask him about it. Trouble is, its his rebuilder who determines if it get warrentied.

Neal: I am coming to the meet on Thursday to give you your dough so you can make pizza

Brian: I called Tom, he hasn't gotten back to me. I think I might just get a brand new turbo so I can have a peace of mind. I didn't know that his turbochargers are rebuilt. No wonder it went bad. There's got to be a leak somewhere.

THIS REALLY SUCKS!!!

to Tom's rebuilt turbos.

Oh yeah, and with the new fuel rails, the intake pipe doesn't fit anymore. Anyone have any suggestions?

Anthony - Sorry I didn't get the chance to get back to you on the VM you left for me.

Talk to Tom, he'll send it back to the turbo rebuilder and have him rebuild it. If you can, you may even want to attach/plug the coolant lines in such a way that you can pressure test it before sending it back to him, to be sure that it is really that that is leaking.

How much coolant came out the exhaust now?

I'd say about 1/3 to 1/2 gallon judging from the coolant on the cement pavement. There was little coming out, but still, it came out.

Were you actually low that coolant in the system after you let it cool down, or did it just drain out of the exhaust from last time?

It was draining out the xehaust, but just like "sipping" and not like a riverflow. The engine sounds normal whe it's idling. I could even hear the leakage of the Blitz SS DD BOV. There were no fluid leaks coming from anywhere underneath the engine.
When i disassembled the turbocharger, and the coolant section smelled something like a pinesol or detergent-like. It did not smell like coolant at all. There were coolant traces when i uninstalled the turbo from the exhaust piping.
Also, under opening the throttle to ~3000RPMs and letting it go, the coolant came out like a spring geyser.
Does anyone know how much a brand new, and not rebuilt or used, T3/T04B turbocharger goes for? I think I've seen it for ~900. Is that right?

On a side note, i saw my know go up to 4 at idle and ~1500RPM.
So, Tom called me, he said to couple the coolant hoses so no coolant goes in the turbocharger, run the car like that for a little and see if I accomplish anything. I might have to pull the oil first and see if it is green or not. Oh well.

Just pulled the oil from the pan. It looks foggy like, not clear brown (brand new oil) like when it went in. I'm suspecting that either Jeremy didn't put the heads on tight enough or the heads were not decked good from warpage.

To check the coolant for oil, open up the top of the radiator while the car is cold and see if any oil is floating on top of the coolant.

You can check the oil (I believe while the car is running) to see if it's frothy or milk-ish through the dipstick and see if any coolant got into the oil.

Wanna see what your oil and coolant will look like if the seals on your turbo are blown?



This is what happens when the exhaust shop bolts your turbo up to test-fit your new turboback and decides to start the car to see how it runs without hooking up the oil or coolant lines to the turbo, blowing the seals. They then deliver it to you and swear they did no such thing. I love them so.

Anyway, with the turbo in that state my car started and ran, but, unsurprisingly, blew lovely clouds of white smoke anywhere off idle.

I removed spark plug #4, did a compression test, came up with ~170psi on that cyl.
Removed spark plug cyl #2, looked gooie, black oil-water combo on the plug. Did a compression test, got a best of 120psi. Well, looks like that side of the head is cracked. I will look for a new replacement head, maybe a used one. Does anyone have any heads for sale here? Wanna get the car back up and running ASAP.

Found whole new engine, 2000RS with 11k miles on it for pretty cheap. It beats me buying new heads, having Jeremy puit them on the block with the cams and putting it back together. It is a crashed RS engine, so they will perform compression & oil tests before selling the engine to me. I'll know by Friday. You guys think this is a good deal?

Why don't you try to put a working engine in the car first before putting the turbokit in. You have a questionable turbo kit. You have a questionable block. You have questionable heads. You have a questionable Link ECU.

You have too many variables working against you.

With so many variables, you can't even begin to define what MIGHT have gone wrong with the current engine.. If it is even the engine and just the turbo.

You will just have to be patient and quit being in such a hurry. Do each stage step by step.

Start with stock everything. Make sure it is all working right.
Move to link ECU and learn to program it.
Move to fuel system.
Then move to turbo kit.

Im with Andrew. Get your engine back up and running in stock config for a little while before going nuts with the kit and everything.

Well, I know the engine is good, and that the driver side head is messed up and sipping coolant through. The engine was working FINE until the head got warmed up and the crack probably expanded. There's NOTHING wrong with the turbokit, NOTHING wrong with the Link+. I considered the new engine keeping in mind costs/labor it will take buying a set of heads, pulling the engine and installing them. For the same amount of money, I will have a working engine in my hands with 11k miles on it. As for the hurrying thing, how would you like not to have a car for 3 months?

Peace!
