turbo blown.. what is the reason??

[talontsi02]

hey i bought a brand new t28killer from a guy and he installed it infront of me(yes it was new) then in less then one day later it started sounding like a jet and then crackling then blew out smoke and died.. im thinking it is because the oil feed line was poorly hooked up and and leaked everywhere.. he said it was because "i boosted" before the 300mile break in point.. which is true? thanks for any input

More likely you didn't prime the turbo before driving.
As soon as your car is turned on, the turbines start a spinning. If you don't prime it prior to, then you'll hurt them. I've got an 18G and there was no 300 mi. break in for me. I installed it Friday night, primed it, drove it around the block and went to bed. Saturday I woke up and drove damn near 200 miles to Fargo, competed in Auto Cross, then drove home with no problems. Well... little problems (It's a DSM).
Yes, you shouldn't have a leaking feed line. That's not going to help you any. Teflon tape people. Teflon tape. Yes, it burns away after it's installed, but it seals with no leaks even after it burns up.
Get a SS line from the filter housing. Teflon tape it at both ends. Fix your oil leaks. Prime your turbo, and have fun. It's a good idea to break it in first, but that won't cause it to go bad in a day. Just prime it before you drive it. Lick it before you... nevermind.

I agree it was most likely because you did not prime it or because of the oil leak. I have never known of there to be a break in period for a turbo. All my friends, including myself, put our turbos on, primed them and then when out and started driving. I have one friend who put his turbo on and then when and put his car on the dyno the same day.

so theres no break in period for the turbo? and sorry for the stupid questions but what is priming.. pouring oil down the feed line or something?

Turbo Priming

basically the act of utilizing a method to prevent the engine from starting, and cranking the motor over several times for several seconds in several intervals, causing the oil pump to force oil throughout the engine, and into the turbo charger. Eliminating the situation were dry oil less bearings are spun and scored.


ive never head of a turbo break in period.
ive thrown on a Brandnew evoIII 16g, and slammed it with 20psi all day long for 20,000 miles and no problems.

Another thing to consider is Overheating.
without proper cooldown procedure for the turbo. baking the oil in the bearings

yeah there really isn't much of a break in period for a turbo. i was actually reading about this earlier today in another thread. so like everyone, i have to say turbo-priming.

 

[vr6chris]

no, there is no break in period for a turbo. sometimes the causes of a blown turbo could be kinked up return line, oil pressure too high and blows the seals of the turbo.

 

[Lordpaxin]

Priming is crutial in turbo installation.

if part of the deal was the guy to install it, he didnt fullfil his part.

he best make good with you somehow, or ~all His rep point belong to us~

 

[talontsi02]

hmm.. ok i'll just look up a thread on priming the turbo then.. this time im just going to do it myself.. ive never heard of a turbo 'break in period' either.. but who knows.. maybe he knows something else that no one else does?

 

[Thomas91169]

also, is the passage between the oil return line and pan clear? a guy i know installed a 16g and when he put the oil return line he got a kink in it which blocked the oil flow and killed the turbo within hours.

 

[talontsi02]

yikes.. no its clear.. the only problem is that the stainless braided line was not threaded all the way.. and he didnt prime it.. he told me that all he did was turn on the car and let it idle for awhile before i came back to get it.. is that an alternative to priming?

 

[talontsi02]

oh another thing that i thought was bad is that the oil feed line is like 3.5 to 4 feet long.. going from: by the oil filter looping down under everything then back up to the top of the turbo.. the mechanic busted the stock feedline so he gave me that one.. could this be a problem aswell?

 

[ddavisaf]

The shorter the better, but it's not bad.

Don't forget to let the car cool down after driving. Wet housing turbos, meaning it's cooled by oil and coolant don't need this as much as dry housing turbos (oil only).
Just make sure you prime the turbo. Take away fuel and spark, crank the car for about 2 minutes with intervals as to not burn out your starter.

 

[talontsi02]

ok cool.. thanks everyone for helping me out

 

[ddavisaf]

Quite welcome. Let us know how the next install goes, and ask any questions if you're unsure of anything. PM me if need be. Replacing turbos suck especially if you're doing in 3 times in a month.
