Stripped hole on turbo for oil return line

[sfriesen]

So I picked up a 16G, and found out after I was close to stabbing the new motor that one of the damn holes for the oil return line was stripped.

Should I just drill larger and tap it for a new bolt I suppose?

I'm going to try to get this fixed withOUT having to pull the turbo back off the motor, as it's got new gaskets and crush washers all over, I don't want to break it back down.

What pisses me off the most is that I was making killer headways tonight, and I would have stabbed the motor and trans in the car if not for this damn stripped hole.

Yeah it be best to take it off that way you can retap with same size or one size bigger and so you are not cramed under the car trying to do this.

trust me you dont want to mess around with the turbo while is still on the car. i had experience like 2weeks ago , i posted a thread but deleted it . My (MHI)BIG16 oil return line bolt was broke inside , i had pics and everything. You cant drill the holes too big ,because there is a pretty thin wall where the bolt goes . Try to retap the same size , or a little bigger . Please dont try to do this while your laying under the car , especially tapping. That was my mistake , after all day working on ONE bolt , i had to bring it to the machine shop and the guy did it for me $10 Dont be afraid to go extra step and take that turbo off , you wont regret. Let us know how its going!!!!

Well, the motor and trans are on the cherry picker in front of the car right now, so I have easy access to the turbo. It looks like someone's already ####ed up the hole well enough that it's a bit enlarged already. I'll probably use the smallest bit I can just to clean up the hole, then chase it with a tap.

what a pain in the ass...

ya i kinda have the same problem. one of the oil return bolts is somewhat stripped and hopefully when i get a ss return line, ill be able to get it out. could i get a new bolt from home depot? the stealership says that they dont have any.

where could i get JUST a SS oil return line? or where can i get the pieces to make one for cheap?

for my oilpan , at stealership i think i paid $1.25 or $1.50 per one bolt . And you all know how many bolts needs 2g turbo oil pan i was soo mad.... but i wanted to go OEM you know

Well I took the turbo off and got it on the workbench, turns out that someone already half assed re-threaded the hole. I got a bolt to work and hold it tight, but when they drilled it they drilled through the end of the threaded opening, so I had to use thread sealer to prevent oil from seeping around the bolt. Fortunately that saved me some time.

told you theres is a thin wall behind the bolt . Well since they drilled thru , do you think any metal piece could have fell inside ? and they threaded it too , there is no way preventing metal pieces falling inside when doing all that stuff , and my friend you dont want to run that turbo if theres metal inside.....
