86 GL-10, EA82T 4x4

I was "seafoaming" the other day and found out I have some serious exhaust leaks in the engine compartment. I've narrowed it down to around the turbo area but since all the exhaust is shrouded I can't see where any leak is. I don't hear any leaks and all I can tell is it's coming from around the turbo. The front & center pipe would be expensive to replace to say the least. Are the inlet & outlet gaskets on the turbo known for leaking?

PM me if you decide to replace the manifold.

ah hah something i know about.

i've been through about 2 or 3 trying to get good ones but they all crack in the same spot.

i wouldnt be supprised if yours has cracked in the same spot as well

 

all the ones i have pulled or bought for cheap crack just behind where the passenger side excahust port meets the rest of the manifold, right before it goes up to the turbo basicly behind all those heat sheilds.

 

i have one that i am fixing that was completely seperated there but i have welded it back together with my cheepo harbor freight wire welder and we'll see if it holds together.

 

some times, like on my car, it cooks those hard black lines and it causes that black coating to melt but on some of the other cars i have pulled those lines were fine so thats not always the case but what you could do is fire th car up and hold your hand arround those heat sheilds and see if you can feel any hot ait comming out from behind then on the passenger side.

 

from what i ahve been told its because the exhaust on that side some straight in instead of comming in at an angle going with the flow of the exhaust. it causes the heat to bulid up more there and the heating up and cooling down over and over causes it to crack. not to mension it probally needed to be 2 peices there because i am sure theres a bit of strain on the pipe at that area too.

 

i've welded one back together and then re enforced it with a thick walled hardened steel exhaust coupler, i'll get some pics of it when i get it cleaned up some to show

Yeah mine cracked near the turbo flange. I've fixed mine twice in the past, and the third time I decided to weld up a header using the existing flanges.

 

are you going under the oil pan with that one from the driver side or is that just how it looks in the pic?

It goes in front of the oil pan, and the stock skid plate still fits just fine.

oh ok it must just be the angle i am seeing it at then
