Turbo Pedestal Leaking Oil
 

I have been having oil leaking out of the bell housing. I know that it is not likely the rear seal. Most times it is something within the valley, then draining to the bell housing at the rear of the valley.

Anyway, after cleaning and scrubbing the engine many times in attempt to find the oil leak, I finally found out that the oil leak is from between the turbo and pedestal.

My question, finally, has anyone ever replaced these o-rings? And if so, how big of a task is it?

not horrible. just time consuming. there are 2 o rings between the block and pedistol and 2 o rings between the pedistol and turbo. spray a good penetrating oil on the clamp holding the "Y" pipe collector to the exhaust housing on the back of the turbo.

Thanks,

I should be able to handle it.

If you haven't already done so, I would suggest doing everything possible back there (if you got the extra cash of course) - 4" downpipe, new clamps, new intercooler boots (or clean them very good), Wicked Wheel (or similar), AIH delete plug, non-EBPV pedestal (the stock pedestal leaks at the actuator arm), high-flow exhaust outlet, and CCV. Then you won't have to mess with it again 'cuz it hurts your knees like crazy. I replaced them o-rings twice before realizing I should have done it all the first time. It was costly but I shouldn't have to work in that cramped spot for awhile.

why would you put in a WW unless you have a surge problem?

^^ i agree, no ww unless u need it cus it drops you surge line by flowing less air thats one thing i would change about my E99 :-(

the e99 has a WW from the factory... i still have surge. to bad you can't get a ported compressor housing...

yea i havnt hit enough hills with a big load too have any surge YET anyways... but yea id like to get an aftermarket fix for more flow anyways...

Well, most diesel guys add sum type of programmer for a bit more power. I mean, driving a 7.3L on a stock setting is sluggish, especially after you see what these motors can do. And most programmers are going to cause surge. But to each their own, it was just my two cents. My apologies.

ive only got a hypertech so maybe thats y i havnt had it yet... maybe it defuels b4 it can surge???

surge happens under 2000 RPM with mine. and when it does it, it's only at about13 PSI. and actually when it first did it i was running stock. and i didn't know what the hell it was! i just have to move my shift points up a few RPM's

Its more luck of the draw Ive had 2 7.3s both were 01's, my first one never surged and the one I have now does it all the time. Kinda goes to say if it aint broke dont fix it.

but you can get rid of it easily on the 99.5- 03 with a ported compressor housing. the e 99's are really a luck of the draw. mine does it and my old boss with the identical truck doesn't.
