turbo bolts

[natertater]

wow, so i am taking stuff apart and checking it out (trying to sell 14b) and prepping for my new mani when it gets here. but the fun thing is, undoing bolts on turbo and two of them snapped off...isnt that grand? i dont think the guy used anti-seize on them when he put the turbo on there over a year ago. so, any suggestions that dont require welding on smaller bolts? should i heat up the car to try to get the other two out? and use some pb blaster or liquid wrench on teh other two?

I would have used PB blaster regardless. I use it on every bolt that is exposed to heat. ESPECIALLY in the engine bay. But I'm thinking torch them and drill them out. Did they break on the turbo/manifold or on the turbo/o2 housing?

I've been there before. Had to take the turbine housing to a machine shop to drill out the broken bolts. What sucks is the shop where my car is at broke a bolt too. Guess what, it was an ARP turbo bolt

awesome. no its on the turbo to mani flange. the front facing two. well, maybe i should go to parts store and pick some up. i am going to go with arp studs/bolts. and totally get the badazz antiseize that wont do this again, hopefully. i pray to god that this turbo isnt hosed!! im trying to sell it to a fellow forum follower and buy a 20g (is that overkill for my basic build for now? i want 400hp later there was a ton of oil sitting in valve cover on top (i will put pic on somewhere later) and a bunch of oil on the pvc side facing towards turbo, but none in the pressure side...guess thats good huh?

Oh and heating up the car won't work. You have the right idea for heat, but you want to heat up and expand the housing around the bolt. Heating up the car would heat both up and it would be the same as trying to get them out cold but now you'd have to worry about burning yourself . Try soaking a ton of pb blaster/liquid wrench in there. Should loosen it up a bit.

 

[natertater]

alright i will try that out. knew i forgot something at parts store...guess i will go back tomorrow then and soak the crap out of it

 

[rocketjr]

Soak and if you can heat the turbo housing up that would be your best bet. I have had to use the torch to heat up sooo many exhaust parts it is funny.

 

[natertater]

yeah i had a benzene torch, but i just need to get the bottles...heat that bad boy up and have it soak before that...hopefully i can get the two busted studs out. one of them actually backed off a few turns, then snapped on me...the other broke right away...

ok putting the 14b in, i picked one up in great condition for 80 bucks. is 1600 degree anti seize good enough? i think its the silver kind. its not the 2600 degree one, but it should last right?

Yes the aluminum/graphite based anti-sieze will work. I took my turbo off a year later with no real problems. The copper based works much better, but I used the other stuff long before I found out about the copper based.

And contrary to what what said, heating up the car makes a HUGE difference in breaking the bolts loose. Don't just idle it though, take it out for a hard pull then loosen them and wear gloves so you don't get burned. You have to heat the car up to get them out if you hot torque them like I do.

turbo is completely out, my butane torch was enough to break it loose, and pb really didnt help much, since where it threaded in was at underside of turbo out of reach/sight. the heat helped. time to get custom 12.9 grade fastenal, or arp chromemoly bolts. oem ones snap all the time, maybe because they use stainless gaskets? i plan on making the bearing grease one, works good and doesnt expand.
