JZ Crank Bolts Sealant

[takai]

Ok, normally i would use another type of thread sealant on the crank bolts, but i dont have any left and i dont want to buy an entire bottle of it for 8 bolts.

Hence anyone think that Loctite 567 wont be up to the job?

Will be fine ,its not a thread locker like 262 but thats where the torque to yeild flywheel bolts of the JZ come into play.

I don't see why not.

Hmmm... if someone was foolish enough to not use thread sealant on his 2JZ crank bolts, would that explain a slow oil drip from the bellhousing even after replacing the rear main seal?

[CrUZida]

I highly doubt it.

So far as i know yes, its an open ended crank into the oil gallery.

I highly doubt it.

Which do you highly doubt, my question or Norbies?


Ill be using ARP bolts, so TTY isnt so much of an issue. That said i hope 567 will work.

In the past ive used 569 which is a high pressure high temp hydraulic sealant with threadlocker: http://www.ellsworth.com/display/pro...2&Tab=Products

If this is the case, its feasible.
But I've never had a crank leak and I haven't always used sealant.

I doubt it would leak that much...it may tho...

It might leak out onto your clutch and cause issues there however...I had this happen to me!

567 is thread tape in a tube.It may or may not work but its not the sort of thing I would put near to the inside of an engine. Any sort of threadlocker would have to be a better option as a sealer.
Save the 567 for when you are putting the air fittings on your rattle gun.

Yes, I just got my new twin plate clutch and it specifies it in there for this reason.

Just bumping this up wondering what people have used for their bolts without a problem...

Manual for my clutch specifies adhesive 1324?

The stock Toyota stuff is precoated.

But Toyota tend to use loctite 243 on other thread that need sealing...

[jeffro ra28]

are the threads somehow linked to pressure gallery? or just crankcase?

Just crankcase.

The threads on the crank are thru, not blind.
