Random Bolt Found

[Y2K2]

I heard a strange noise from the engine,

looked around and found a loose bolt was rubbing against the belts.

It has the number 4 on the head and is about 4 or 5 inches long (will messure it when i get home from work).

The car is running ok without it but I am to worried to drive it.

Does anyone have any idea where a bolt like this may go?

The car is a R32 gtr '90

What size bolt is it? (measurement across the thread)

Def a long bolt but need to know what size as well

My guess is that it was holding the alternator/ps pump/aircon pump. Have a look - alternator bolts to the block with one of those, but its low down and hard to see. Look on the engine side of the pulley.

A photo would help.

No Adam, a little skinny long bolt like that will be the power steer tensioner or maybe the alternator tensioner.

Aircon tensioner would fall straight out on the road and the alternator pivot bolt is a decent diameter. (17mm head with a 14mm nut)

I'd put money on the power steer tensioner, impossible to see etc etc.

100% agree. And I've left one loose before, they vibrate out over time and rub on the pulley (mad sparks on the dyno!)
