600 series isx oil leak Hello all I have a 600 series isx 07 Pete 379.I purchased from a private seller who lied about everything. So it's leaking oil bad and I took it to peterbilt and they threw a turbo and valve cover at it for 8000. Well it didn't last long and the leak was back. It leaks everywhere! I can't tell exactly where. It puddles at the back of the engine on top of bell housing and puddles on ground directly under passenger side. Driver side stays way cleaner. There is oil in front of engine back and passenger mostly. Steps and everything underneath getting covered. The other day when I was checking oil the cap wanted to forcibly come off. Whitish clear smoke or steam constant coming out. Valve cover after 400 miles now has 4 cracked bolt hole all the center ones. Guy said he rebuilt it at 42000 ago which is 50000 now. He has not sent my papers like he said he would and is a complete liar. So when I find out the thing wasn't rebuilt I will go from there. Bit any ideas whay this leak is it goes everywhere and only under load heavy leaking?? Thanks[/size] | |||

RE: 600 series isx oil leak Could be rear structure leaking, or the back of the head. Pressure wash it off real good then drive it around a little and see if you can tell where its coming from. What's your oil pressure when driving loaded? | |||

RE: 600 series isx oil leak You need to determine if the CCV is stopped up and if the blowby is excessive and the cause first before you start chasing oil leaks. | |||

RE: 600 series isx oil leak He may very well have had it rebuilt, but based off the info and many examples within this forum alone, a poor inframe and/or improper tuning is detrimental to an ISX. | |||
