Default 75 L48 why is idler arm almost touching exhaust?

close. about 1/8th inch. i would think that much heat would be rough on the bushing.

ok, looks like arm and exh are in contact. it is a newer replacement arm. exhaust looks original, with heat riser. ok, pic went thru. motor mount looks ok. any thoughts? or anybody have a pic of theirs? i guess i could loosen the mounts and scootch motor over a bit?

Mine is very close to the exhaust as well...heavy duty idler replaced in the 80's...yes the 80's....no adverse effect from being close to the exhaust.

The idler arm may get pretty hot when its sitting still and idling but when you're driving down the road there's a LOT of wind blowing past it.
