4.6 4v woes
#11
The seals were replaced when I did the O'haul. I knew I was going to have a bearing problem but with 114,000 miles I wasn't expecting to do a bore job and that is where things went wrong. I was left with a choice of paying $3800 for a used engine with 130,000 miles on it or do a rebuild and to Me that was a no brainer. the cooler has to be cracked internally. I know the engine got very hot as both knock sensors were melted. Block and heads were pressure tested and magnafluxed so I am thinking the cooler has to be the problem
