Not real easy and when they get this old the bolts somtimes break off. also check for crack in the exast manifold. when you get them off you should have them surfaced.
i always put them on without gaskets and they seem to do better.

    no there isnt a quick easy way to seal the leak you will need to remove it and have it resurfaced.

    just a note dont force the bolts out you will need to remove them real smooth so you dont break them off. and the bolt that is missing broken off or fell out?

    the onlly way to stop the leak is to remove it and have it surfaced.

    good luck and hope you dont have any bolts break

Was the question answered? is this a cast iron manifold? the reason for the leak is the bolt falling out allowed the manifold to warp, once warped just putting the bolt back in won't stop the leak, the factory doesn't use gaskets on the manifold in most cases unless they are factory tubular exhaust, you can pull the manifold and have a machine shop true the mating surface if it isn't cracked, you can also get an aftermarket gasket, but that is a short term fix and the gasket will blow out in a monthe or so.

Lifter noise

by changing the exhaust I take it that you removed the standard exhaust manifold and fitted extractors in instead. The noise may not be lifters but a exhaust leak form the exhaust not being fitted properly (gasket ) or just and gas noise as the exhaust valve opens that is normally silenced by a stock manifold.

Car over heats both fans working and i have a new thermostat.Even checked water pump to make sure it's ok. very frustrating1!!!!!

Flush coolant system out. If this does'nt help check for white smoke coming out of exhuast while its running.White smoke from exhuast would mean that coolant is getting into one or more of the cylinders,which would mean more than likely a blown head gasket.A blown head gasket would cause it to over heat.If you are loosing coolant and don't no where its going would be good sign that its blown.You would need to proform a leak down test on each cylinder this would let you known which cylinder is the problem.

No heat smell burning antifreeze in exhuast

if you are smelling anti-freeze in the exhaust system and have no heat then you probably have a head gasket that is bad leaking anti-freeze into the combustion chamber and being burnt.the head gasket will need replacing.if the motor hasn`t gotten overly hot then the cylinder head is probably okay.

2003 dodge ram 1500 5.7 hemi replaced piston and head now have tapping noise from front of engine. sounded like exhuast leak replaced gasket. not loud at idle but when start driven gets loud.

Could be a bad gasket tightness if you replaced the gasket. The exhaust manifold could be not torqued down evenly causing a gap to exist allowing exhaust gas vapor and sound to escape at the cylinder head connection.

My 1996 chevy suburban wont start

If you plugged the original leak (which sounds like the head gasket) and then the radiator was leaking, and you are having water coming out of the exhaust, then you need to replace the head gaskets. It sounds like you had a blown head gasket from the start. Here's what to do.

1. Replace the head gaskets (will need intake manifold gasket as it need to come off for this procedure).

2. Replace thermostat, radiator cap (if radiator is still good)

3. Replace water pump; the water pump may have stopped working (mechanical), which in turn caused the pressure to build an blow the head gasket (the cause of the pump would be a bad thermostat. If the truck was overheating, then the thermostat was bad to begin with, then the pump, then the head gasket, so then the only place left for the water to go is out the exhaust.

Here is a list of replacements:

^ water pump
^ thermostat
^ head gaskets
^ valve cover gaskets
^ radiator cap (if radiator is good)
^ radiator : if leak from cap caused any damage to radiator (should still be good)

**Also check the radiator hoses to ensure they do not have any "bubbles". Hot water over time (with anti-freeze) erodes the inside of the hoses, and begins to "dig" holes and grooves in the hose, which evetually cause leaks. Consider replacing these as well for safe measure.

Please, let me know if you need further assistance.

the color of the antifreeze will have zero effect on the problem you are having.  I suspect the replacement engine has a leaking manifold gasket or a blown head gasket.  Why would you buy an engine with that many miles on it?
