cracked sleeve how to tell?? I have a 408ci dry sleeve motor, felpro gaskets, vortech T-trim SC running about 6lbs of boost on 6.0L heads. About 2000 miles on motor.
How can you tell if you have a cracked sleeve or just a blown gasket without taking off the heads???
Are there any tell tell signs its a cracked sleeve vs just a blown head gasket??
Here is what is happening.
cylinder #5
coolant is found in oil
steam coming from oil fill
steam coming from exhaust
compression test on #5 failed
anything else i need to look for??? tuner is on vacation for the next 10 days, so cant take off heads to make sure its not a head gasket until then. Thanks for the input.

When you test for compression or do a leak down, leave the plugs out of the #3 and #7 cyl. if the gasket is bad between the cyls. you will hear air rushing out of the plug holes. If you hear air comming from the crancase, could be a sleeve or gasket, if you hear air coming from the cooling system, still could be the gasket but prolly the sleeve. Whatever it is, it ain't good
Good Luck
