Lookie here...

So... as I took on the adventure of changing out the hubby's turbo, I came across some interesting finds. First... the old turbo is a Garrett. woohoo. Second... the old turbo and manifold seriously gave up. They were just plain tired . I have pictures of said items.

Please notice the ginormous crack on the left.

smoky white.

Please also take notice of the cracks in here.

So what exactly caused these guys to crack? Just age? I understand these parts see some pretty extreme heat... but is that it? I just want to make sure it's not caused by something else because if this happens again, I won't be the one changing it out! This will probably be my first and last turbo swap . Comments are welcome

It's a matter of heat and age. After a while it will happen to most. Replace it with a fp manifold and you won't be disappointed.

Already got just a stock replacement. Painted it black with the "extreme heat" spray can just to make it look nice Painted the heat shield with the same paint too since it was looking a little sad also. Broke one of the old manifold studs too That's when I called it quits for the night.

Honestly i doubt the paint will hold. Have you ever popped the hood and looked at the turbo after drivin it decently hard? We had a intercooler pipe blow off while out messin around on some back roads. We didnt have a heat shield on it. The mani fold was so hot it was glowing red. It was bright enough we used the light from it to reconnect the pipe.

Good grief. And I don't drive this car if I don't have to. I prefer my truck. The Eclipse is honestly too low for my back. (I have a slipped disc and some pinched nerves) and it hurts to crawl out of. I've got a little 96 GS project that needs lots of love but I seriously doubt it will ever see a turbo. But I do know that my husband called me one day while heading to one of his buddies' houses and told me to bring him some tools because one of the intercooler pipes popped off. And this car has had it's heat shield since we got it. He only recently took it off when he took this turbo off the last time because he thought one he found was "bigger." He's one of those guys that just wants to go fast and consequences be damned!

Yeah we where like that back in the day til we went through like 10 of these motors. Finally ended up goin with a Evo 3 motor in the 98 and i sold the 91. now back into it again.

Many heat cycles and age will start the cracks to happen. Very common on the wastegate hole.

Turbine is white from a lean mixture and if the turbo is the stock one from the 2g; the T25 is made by Garrett...it's still crap

Turbine is white from a lean mixture

The white turbine doesn't necessarily denote a lean condition; in fact, if I receive a turbo for rebuild and the turbine is any color other than white or very light brown then I can guess than the owner has a tuning problem.

Now if the entire inside of the manifold and turbine housing inlet is white as well, the car is definitely lean. These pictures show a perfectly-functioning turbo system.

Following me around tonight aren't you

That is 100% true but usually a white color indicates either a high temperature or a leaner fuel mixture. Since the turbine would be in the "high temperature" range then yes that's acceptable.

Shocking as most wheels that are posted on here have bad seals with a dirty looking wheel.

the heat paint i did the same to my car its held up on the shields.. but the mani, it smoked it off fast

 

[SD99GST]

Yeah those manifolds take there abuse well for the age. But to me that seems completely normal wear and tear. Mine had a lot of cracks on the underside of the mani that I couldn't see, but whe i removed it to do a turbo swap I couldn't believe how many and the size of the cracks. Very nice of you to do the hubby's turbo

The first turbo you do is always a pain... but after that, gets very easy and almost routine. I don't even mind doing it anymore. Not sure if you did or not but try using PB blaster before removing any of the exhaust system bolts, worked very well for me.

 

[ktgurl87]

Welp... I woke up so extremely sore this morning I could barely move. Now that i've told the hubby that I got the new turbo in, he wants a new "racing" radiator and a new starter. A new starter I'll go with but I dunno about the radiator. I also bought some easy-outs today at work to get that little #%!^$#~ manifold stud out. Gonna wait a day though so my arms can go to feeling normal again. I don't think I've ever cussed so much in one night in my life!

 

[enzo5190]

yea those manifold studs are a pain in the @$$ to get out

 

[dirtyhurricane]

yea those manifold studs are a pain in the @$$ to get out

Yea they are, had to do it last weekend!

 

[2GbTalonGuy]

Really? My exhaust mani studs came out easy. Just let them soak in penetrant for a day ot two before you try to remobe them. Works every time for me.

 

[ktgurl87]

i was told one little trick to take them out is to put 2 nuts on them and screw it out using the back nut. i just don't want to break anymore and if i spray some pb blaster on them or something, should i plug the holes from the head? i don't want to hurt anything. i don't know if penetrating stuff would hurt anything just inside there but i don't wanna take any chances.

 

[cantgo2fast]

Ya that paint wont last on the manifold. After years of extreme heat cycling any metal is going to lose its strength. Ex: the challenger disaster

At least all of your manifold studs are still in the head

 

[ktgurl87]

well i bought a whole new set so i'm hoping the rest come out with little difficulty. cross your fingers for me on that one.
