In the meantime, clean the area well including the chain tensioner cap and carefully apply JB wend into the cut. It will form threads to seal (and help keep the JB Weld in place). Apply to cold, clean surface in the afternoon where it's not too cold.
When I recover the cover, I'll recover the timing chain tensioner cap and washer as well.
What a drag. Sorry you're gong through all this. TI fun...
This actually reminds me, I need to locate the same cover and emissions assembly for my rebuild. Worse case, I'll send you one off my M44 as it the same one as yours as I need a late models timing chain cover in the event the Pick n Pull one is gone next week.
Either way you'll have one. PM me shipping info once I have one in hand.
