stacks and washing
 

so i just put stack on my truck and im a little concerned with washing my truck...i know the pipe has a weep hole in the bottom but i wash my truck at self wash 18 wheeler bay that are very high pressure...so im concerned is it ok to wash around the tip and get some water in there or should i avoid it and do that part by hand and if i do it at the wash bays should i leave the truck runnin so theres some heat and back pressure

I wouldn't worry about gettin water down the stack to flood it out, your gonna need ALOT of water to do that! But I'd be worried for another reason... After your done washin the truck makin it look pretty, when you go to start the truck it's gonna shoot wet soot all over the truck and wreck Your wash job and your day...

thats true i live in CO a have had a foot of snow on top of my truck and in the stacks, does not hurt a thing. The only thing is u will have little black dots all over your truck if u get too much water in the stacks
