Unless I'm blind or simply can't read, i'm not finding the torque spec for the bolts to the oil pan (sump) for the VP 5.0 GXI-E (305). I've found online Merc people are using anywhere from 8-10 ft/lbs and several places online for the auto people say ~8 ft/lbs if pan has 14 bolts (which it does). I know on my 3/4 truck the bolts are torqued to 9 ft/lbs so my assumption is if i use 9 i shoud be good to go. But, being marine, like my darn diesel truck, there's always exceptions for these most times :) I seriously don't want to have to pull this engine again for a bonehead torque setting i screwed up.

Is there a correct torque spec for these bolts, or can i (like the info-mercial), set it and forget it at 9 ft/lb?

THanks!

To clarify, i did find the 4 studs are 53 in/lb. Just not the other 14 bolts. no mention they should be the same torque though.

ignore me. i simply can't read. 4 pan studs @ 53 in/lb", 4 pan stud nuts @ 18ft/lb, all other bolts 106 in/lb (or ~9 ft/lb).

i seriously have been going through the manual for a while and i don't know why that darn chart on page 156 wasn't visible :) Prolly cause i was looking for Oil Sump and not Oil Pan.

3 ugga-duggas on the chordless impact....

seriously, the pan should be 12 ft-lb on an SBC oil pan. nothing special about marine or not, it is still a GM SBC

Like a valve cover you get it nice and snug but not so tight that it distorts the pan rails or gasket. Every few years when I have all the seats out etc I check the bolts on the pan, timing cover, bolt that holds on the dipstick tube, starter bolts and exhaust bolts.

3 ugga-duggas? HA! i'll have to remember that technical phrase.
Seriously...as a SeaBee (electrician), i had a UT (plumber) teach me the 'proper' way to glue PVC fittings when we were deployed to Iraq. Apply primer, count to 10 Mississippi's (i thought it was because I live in Mississippi). Apply glue, press together with a slight twist. Then, smoke one cig to allow to dry and set. Not advocating smoking, but i swear the first two i did i didn't wait the mandatory smoke break and as soon as pressure was applied the joints came apart. To this day, i still wait the 'mandatory smoke' break before applying liquid pressure :)


And thanks for the info to LC :)
