I love my Cats but the aluminum pan on these things drives me nuts.....i digress... slight crack in the pan has re appeared, it was welded slightly before i bought the truck 3 years ago and im just wondering if they ever stay welded when they try to fix them or if its just easier to go get another pan, either aftermarket or factory.....

suggestions??????

thanks guys

by the way its the truck in my sig

 

depends on where the crack is, close to the bolts= get a good used one. side or bottom, take it to a GOOD aluminum welder. at least you don't have that Detroit plastic pan, one good hit and 10 gallons of oil on the ground

 

You should change all the isolators on the oil pan bolts when the pan is down. What is the max rpm on your motor? was it cranked up? I know Cats are real sensitive to higher rpm without changing the balancer.

 

99% of the time that I change a series60 oil pan is because some retard has put a tiger torch on it to try and start it in the winter.

 

it will spin to 2100, factory rated at 475 and 1650, turned up before i got it to 550 and 1850, reflashed at the same 550/1850 when finning inframed it a year and a half ago

 

Thats a good names in the industry so I am hesitant to ask, Was the engine ever rated to 1750 rmp max? Has the balancer been changed at all?

I would really like to believe when Finning inframed it he changed out the balancer.

keep us posted.

 

I do not know if it was ever set to turn that slow.. it was 11 yrs old with 1,079,000 on it when i got it, however it was a fleet spec truck out of ontario in its early life.. I will recheck my invoice and see if a balancer shows up on there, but i cant remember one its been a while since i looked haha

 

i will try to get a picture of it tomorrow and post it too if that helps any
