i just had the motor rebuilt and put a milodon 10 qt pan on my olds 455. the problem is...... there is a small hole on the top part where the welds come together. looks like a defective pan. :screwy: is there anyway to fix that without pulling the motor and taking the pan baack ??
also when the motor is hot its hard to crank... im thinking the startor is getting to hot and may need a rebuild ??

Temporary fix on the pan- J.B. Weld (still holding a rock dent/rip in the diff cover on a CJ7)
Permanent fix-Pull the pan and Tig weld it
Hard start? to much initial timing? Do you have a ford type solenoid inline? every GM starter I have has a ford type solenoid inline.

Mash on it

Might talk to the engine builder about your problems, most good ones would be happy to help you out and make sure you are happy. Too bad about the pan, nothing worse than an oil leak in a boat.
Before pulling the starter, you might want to double check all your cable connections,, as a loose or dirty connection will create resistance.

yeah i was thinking the same thing. clean it real good and sand a little then jb weld it or get some liquid metal on it. the problem is.... if i do that i cant return the pan. the engine builder said if i take the motor back out and to him, he will get a new pan and put it on. so do i wanna pull the motor back out or just jb weld and hope for the best ??? :screwy:
on the startign issue it just started doing it the last day i was at havasu. when the motor is cold it starts fine but when its hot thats when it struggles. we did the pertronix conversion on the dizz to get rid of the points. could that be an issue ? i checked the terminals and the lead going to the startor had some oil on it but not much

pull it out and take it back.
only a couple hours and you will thank yourself later! just .02

Worse case...The bearing clearence maybe to tight, when they heat up they expand, if they are to tight they have no where to go. Just my guess...
Does it ever die after you have been running it for a while? Maybe pickup in the distributor.???
P.S. I hope im wrong, but this did happen to me. I bought the boat that way. Now im rebuilding the motor...& when I pulled it apart it seemed to be a fresh rebuild.
