Have heard many different opinions on this. I'm talking about the 4 bolts that mount the engine (EVO) to the frame and the 5 studs/nuts that mount the transmission to the frame. Shop manual doesn't mention loctite in either case.

 

Question is, why wouldn't you?

 

I would. Just curious why its not specified in the manual??

 

because any where there is heat loctite stays liquid.

 

Edit: But what about loctite used on cylinder head bolts and other internals??

 

does the manual talk about lock washers ? if not just torque the bolts.

 

Sure if you never intend to take the thing apart. Head bolts are lightly oiled and torqued. I anti seize my engine mounting bolts.

 

Not true. Absence of air will set the loctite not lack of heat.

 

Some habits are good and from my days of riding shovelheads external stuff gets Loctite. If I didn't it usually wasn't there by the end of the day. I definitely wouldn't use it on headbolts cause it would be difficult to get an accurate torque. I would deffinately use it on your mounting bolts for engine and tranny mounts just for piece of mind. It really ruins your day to have a stud come loose on the tranny. As for getting them loose make sure you use the right product to start with and a little heat helps. Know there are different grades like blue for most fasteners that will possibly be removed again in their life time. Red is for serious holding when you think you'll never take it off again and if you do heat helps. Green is you're not going to take it apart without a lot of cussing and throwing stuff around. And the book does call for Loctite occasionally. Cam sprocket bolts come to mind for tc.

 

Thank you! So blue for engine and tranny mounts??
