on a ls1 are the

oil pump
oil pan (except rears)
front/rear cover
cam gear
vally cover
timing chain tensioner
cam retainer
bolts all the same? i know the threads are but the leingth and everything the same?

and on the puckup tube for the oil pump theres 2 holes in the pump for bolts but my pickup only has 1? and i think its missing an o ring on it? is that a gm piece? got a part number?

 

Not sure about the sizes... I can tell you that my pickup tube also only has one bolt that connects to the pump (although the pump allows for two bolts) so don't worry about it.

 

There is only 1 bolt hole on the pump, so don't worry about it. The part number for the pick-up gasket is: 12557752 on the ws6store.com site.

 

no not all the bolts are the same length. The oil pan consist of 3 separate size bolts....etc.

 

which ones are differant leingths? i thougght that pan wazs all the same except the rear 2?
