How many bolts for oil pump?

[dsmalaska]

Okay I can not find this info anywhere. I'm about to put my oil pump on but I have (5) short bolts with the number 4 on them. I know they go with the oil pump but I feel like there should be more bolts for the extra holes. It's been 5-5 1/2 months since I took the motor apart(machine shop took there sweet time..) so I kind of forgot where it all went. any help would be awesome!

Are you talking about the entire front case or the oil pump cover (bolts to backside of front case)?

The front case has 12 bolts:

Okay so I found my box with all my old tensioners,water pump, etc with all the bolts but I still don't where they go... I had them put with what they went with but must have fallen out when I was movin the box around.

Alright, well there's a diagram for you in post #2. 12 bolts + 1 for the bshaft belt tensioner.

Awesome that helps out a lot! But it doesn't show all the other bolts...

Here's a real life one!

All that "helpful" diagram says is the wrench or socket size needed for the original bolt heads. If you're going to use something to identify what goes where, use the diagram provided in post #2. The hydraulic tensioner bolts are 51mm but have a neck down and should be fairly obvious.

The original bolt for the balance shaft tensioner is 45mm long; if you're eliminating the balance shafts, you need a bolt 16mm long.

Do you happen to know the torque for the front cover

 

[19Eclipse90]

Sure. What Size is That Bolt, Nut, Stud, Fastener? (1G version)

14-16 ft.-lbs. for all 8mm bolts, 20-25 ft.-lbs. for the only large 10mm bolt. Timing tensioner bolts are 14-20 ft.-lbs.
