leaking anti freez - 3/31/2007 4:33:32 PM    El Jefe   Posts: 13 Joined: 3/31/2007 Status: offline Hi, i'm new. i do not own a rover, but i'm working on my sister-in-laws 99 Dicovery II. i hope i can get some help from you guys. k, it started to leak antifreeze real bad on the drivers side. looked as if it was coming from the head, like a blown head gasket. well i just got the head off, and the gasket looks fine, can't find a crack in the head or block. what the heck else could it be?

Land Rover made a kit to fix this. If you don't hear back from anyone else, re-post this in the discovery section, or search that forum. There are posts about it there... Good luck!

By the way, you can't inspect a head gasket by looking for cracks, the best way to verify if the head gasket is leaking is to due a pressure test on the coolant system.

RE: leaking anti freez - 4/2/2007 7:38:16 PM    El Jefe   Posts: 13 Joined: 3/31/2007 Status: offline i put a straight edge on it, found a couple spots that are warped, but not where it was leaking. also, there is no trails on the head gasket to indicate its leakage passage. but you can see where the gasket wasn't sealed properly. weird. i'm taking the head to the shop tomorrow. i'll have him check for warpage, and any possible cracks i can't see. and then mill it down if necessary. thanks for your help.
