can i just use high temp adhesive to hold in the o ring for the front cover? or do i need hylomar thanks

 

i've used hylomar only.

 

You only need to hold it in during assembly. If the engine is on a stand, just position it so the front iron is facing up. If it's in the car, then just use Vasceline. The o-ring itself requires no sealant to do it's job.
