Turbo went and back pressure spiked you think!? Just thinking outloud, as i know nothing about 6.4s

i wonder how that could have happeend? I dont know, but i do know that you should look at the wastegate good and hard and make sure its all good

Is high pressure turbo the big one?

Dzchey21 · Jul 28, 2011

no its the smaller one, on a 6.4 its the vgt turbo driver side

bigrpowr · Jul 28, 2011

It's only the seals. Not sure what causes the seals to go. Stalling?

Dzchey21 · Jul 28, 2011

on the compressor or exhaust side? Alot of time thats high crank case pressure

I have a bad feeling I destroyed the same.

im thinking the same erik

White_monster · Jul 28, 2011

I think Erik wrecked a piston and some debris went thru the turbos. I've talked to him lots and that seems like the logical chain OC events but without seeing the engine I can't confirm it.

Sigh......ohhh to be a dumb ass.....

Mine was probably all due to a sticking wg and shouldn't been driving it. Didn't know any better. Also blew lower radiator hose earlier in the day saw 220 h20 and 230 oil temp before stopping. At a shop now waiting on the findings.

bigrpowr · Jul 28, 2011

i think dustin nailed it, when he said cc pressure pushed oil past the seals. even though it may be fine, i be taking no chances.

Erikclaw · Jul 28, 2011

It isn't worth it, not making sure it is all right.

BFT · Jul 28, 2011

probably drill another whole in the valve cover and have a bung welded for more venting?

i kinda had a feeling one of the turbos may have been hurt. sucks to know about the piston. how do the heads look?

like a german army helmet. maybe a fire fighter?

thats not good.......

Are these gates failing because of the heat generated where they are located?

Maybe the water cooled Tial gate that Dustin posted is the answer.

After hearing about Eriks and Mikes(if the gate caused it) I am concerned that this may become an ongoing issue.
With the heat generated from daily driving I am starting to think the gates internals are going bad causing the gate to fail, which then takes a turbo out.

Haller.....any results from the truck you installed one on?

I think I am going to go ahead and have Aaron switch mine over to the Tial and run water. I dont think Im going to be happy if I have to pull the cab again for this problem.

Erik/Mike are you guys going to do anything different than before in regards to the Precision gate?

Discuss......
