2001 E7 460 cylinder liner removal...please help!

Recommended Posts

Longtime lurker, love the site...started an in-frame on my 2001 cx, and none of the liners will budge. Tried huge puller, jacking from underneath while pulling from top, going to try liquid nitrogen to freeze them out, but doesn't look promising. Can you use the welding method on wet liners? Mechanic used it on the old dry ones, but isn't sure about the newer wet liners. Any help is greatly appreciated... I need to get her back on the road!

If you get the right liner puller they will come out.About the welding deal if you try that make sure to cover the crank.I have seen some one do that and let ding berries get in the oil hole of the crank.

Thanks to you both for the quick answers. Our concern with welding is that the E7 block has a void around the liner for coolant to flow through, and we fear welding may damage that somehow.

Welding worked...someone applied some kind of sealant to the outside of the whole sleeve, providing an insanely strong bond to the block, making our lives miserable for the past few days.
