exhaust manifold stud oil galley

[94nonturboGS]

What is the best way to seal up the oil galley behind the middle exhaust manifold stud? I am drilling and tapping new threads and installing helicoils on all of the studs because they all stripped out. Is there some sort of compound I can use for this? Any help is greatly appreciated, thanks!

The coil will seal up just fine. Take your valve cover off and put a magnet to catch as much shavings as possible. And yeah I know its an aluminum head, the shaving will still stick some what. Make sure it is nice and straight, otherwise the manifold will not slide over a crooked stud.

http://www.antiseize.com they should have something to fit the bill though.

I was reading on here that you need to seal it up though, thats why I was asking because people said you needed to seal it with something other than just a stud

 

[95burgundyesi]

Hmm, well then use one of those anti seize sealer products. On the stock oil filter housing there are hex plugs not used, and from the factory the threads have a green colored sealer on them. That seams to seal against oil. Go with that for the stud.

With soft metals like aluminum, copper, ect sealant is not needed on threads but it won't hurt. I personally don't like heli-coils cause they have always failed on me. I would rather oversize the threads and restud them then open the mani bolt holes. Is there a such thing as a stud with 10x125 on one side and 8x125 on the other? that would pull a premium.

Hmm never heard of this galley, is this a result of your drilling or does it go through from the factory?

I use Permatex No. 2 on that stud:

retapping threads was not an option for me here, for some reason they were still stripping out

It's from the factory i would have been more upset if it was something I did

is that the same as rtv black? I have some of that at home

The center bottom stud goes into the galley from the factory, to the question above. I saw a fire start because it shot oil on the manifold at highway speeds haha it was insane.

 

[94nonturboGS]

going to bump this thread because I tried the permatex #2 and it is still leaking out a little bit, what other options do i have? just cover the whole stud and nut in that permatex #2? I know it wont look the greatest but I have to seal it somehow!

 

[rlacasse1]

When I did mine i just put some black rtv silicone on the stud and it sealed it up fine. Absolutely no leaking from that stud.

 

[94nonturboGS]

might have to try that now then! Because I'm running out of ideas haha

The only problem is it has to be rated high enough temp wise

 

[Boomdeeze]

Any update on this? I am having this problem right now and I'm trying to find a solution. I found a red loctite that seems that it would work but would I be able to get it back out if I needed to and do you think it would work?

Heres the link to the stuff I'm looking at:
30g LOCTITE 2620 High Temp High Strength Threadlocker | Fastenal

 

[daren_p]

Make sure the hole is clean & oil free before any sealent is applied, if its not, it will probably leak. I used Permatex Thread sealent (believe just their "high performance" stuff. Haven't had any issues with it.

 

[Boomdeeze]

Can you buy that "High performance" stuff at any local hardware store or auto parts store?

 

[And_44]

Mine has been stripped. Havnt had time to remove turbo to get the right angle to oversize. Ive tried rethreading but hole is to far gone. But for now I've used copper rtv in the hole going onto a year with out any problem.

 

[RvlutionMtrsprt]

What about using a heli-coil to keep it the same size? And I've had black rtv, hondabond and loctite all work well for sealing that hole up.

 

[Boomdeeze]

Would the ultra Blue RTV work? I used it on the bolt to block the feed line from the head and on the bolt on the front case when you delete the balance shaft belt, nether of them have leaked in over 1500 miles. Would it hold up for the stud too? I also have a tube of "The Right Stuff", could that even work?

 

[daren_p]

I hear alot of guys say "The Right Stuff" & the Grey RTV are great for sealing things. And yes I believe you should be able to get the Permatex Thread sealent at most local auto parts stores that carry Permatex.

Not honestly sure what that bolt gets up to temperature wise...but teflon tape..the same stuff used for plumbing will hold at almost 600 degrees...and that'll seal it for sure.

I know this is an old thread but there is very little agreement on the topic. It's strange that it's not anywhere to be found in the fsm. I found some permatex high temperature thread sealant, any thoughts?[DOUBLEPOST=1409454549][/DOUBLEPOST]Here is from the permatex site:
OEM specified. Locks and seals threaded fittings. Resists leakage, vibration loosening, moisture, hydraulic fluids and diesel fuels. Lubricates threads for easy assembly and disassembly.Won’t shred or wear like Teflon® tape. Parts may be repositioned up to 4 hours after application. Temperature range -65°F to 400°F (-54°C to 204°C). Contains PTFE. Permatex® Thread Sealants seal and secure metal pipes and fittings. By filling the space between threaded metal parts, Thread Sealants cure to a pliable seal to prevent leakage caused by vibration loosening, tape shredding, solvent evaporation, damaged threads, and temperature cycling. Designed for low and high pressure applications, Thread Sealants seal instantly for on-line low pressure testing. When fully cured, they seal to the burst strength of most piping systems. The high lubricating properties of Permatex® Thread Sealants ease assembly and prevent galling of the threads. For system repairs, parts may be disassembled with basic hand tools. - See more at: http://www.permatex.com/products-2/...re-thread-sealant-detail#sthash.HFsE0qv6.dpuf[DOUBLEPOST=1409454835][/DOUBLEPOST]Suggested Applications: Head bolts into through holes, oil PSI sending units and sensors, oil and coolant lines, fuel fittings, rear axle fill plug, brake and power steering fittings

My only concerns is that it looks like it is for tapered threads.

I personally prefer 3m like 3bond, hondabond, mitsubond etc. Just be sure to not put a huge amount cause it does thread into oil passage and it could get lodged somewhere it might do damage. Permatex is good enough though, prep is everything either way so like daren_p said clean it good and you should be golden.
