maredlin1@hotmail.com Posted April 25, 2015 Report Share Posted April 25, 2015 What if you start a rebuilt engine without water (no water pump belt) and let it get hot. Would it let your head gasket seal without the the intrusion of water getting into the inporftions of the head and bock ? Quote Link to comment
shacks510 Posted April 25, 2015 Report Share Posted April 25, 2015 Not a good idea. Quote Link to comment
datzenmike Posted April 25, 2015 Report Share Posted April 25, 2015 Define 'let it get hot'. You can run it briefly without water, but the combustion chambers will get very hot very fast. There's no reason you should run it without water just because the water pump belt is missing. Quote Link to comment
Jester Posted April 25, 2015 Report Share Posted April 25, 2015 I think it's one thing to be starting up a fresh engine and the belt fell off. Not a big deal. To PURPOSEFULLY fire it up and let it "GET HOT" is insane! I don't think you realize how fast that thing is going to get hot. Quote Link to comment
kelowg Posted April 25, 2015 Report Share Posted April 25, 2015 Hg seals with compression from bolts clamping force. temp has nothing to do with it. Quote Link to comment

Why the fcuk you would run it for any more than the briefest of periods without water is beyond me. Alloy heads like their cooling ! 1 Quote Link to comment

shacks510 Posted April 26, 2015 Report Share Posted April 26, 2015 I read online that running the engine without oil helps break in the bearings. 1 Quote Link to comment

Would it let your head gasket seal without the the intrusion of water getting into the inporftions of the head and bock ? It is phrased as a 'What if" All I can add is that the gasket should seal hot or cold as long as the two mating surfaces and reasonably flat. Over heating an engine (specially one with an aluminum head) is the leading cause of the head warping. A warped head can easily exceed the gasket's ability to seal the gap between them.

docbainey Posted April 26, 2015 Report Share Posted April 26, 2015 As stated above, 'hot' and aluminum head do not go together to well. At the least, it will give you practice rebuilding L engines. 1 Quote Link to comment
