szebban Posted February 11, 2014 Report Posted February 11, 2014 (edited) Hello guys! So this is the story, i hade du replace the mainfold gasket on my dodge every thing worked fine before i drove it into the garage except the leak from the broken gasket. Its a original fleathead 6 in it so I followed the steps in my shop manual that i got and evertything went smooth, no problems what so ever. But then i were done and filled up the radiator again and noticed a water leak from the two long bolts in the mainfold, so i fixed the leak and took it for a test drive. right away i noticed i was ALOT of white smoke so i stopped and checked the oil and the water level in the radiator everything was fine. The smoking didnt stop so i drove right away to the garage to try to find out whats wrong with it, i took the cap of from the radiator and i was a bit smelly from the gases and i noticed some of this brown stuff on the radiator cap and on the surface of the water.Still no water in the oil but i cant figure this out. So now i need help. Edited February 11, 2014 by szebban Quote
Don Coatney Posted February 11, 2014 Report Posted February 11, 2014 Many of the manifold studs penetrate the water jacket in the engine block. A thread sealant (pipe dope) should be used on all manifold studs. Quote
55 Fargo Posted February 11, 2014 Report Posted February 11, 2014 if any stud, or those 2 long bolts leak some anti-freeze, it will burn on manifold and smell. The brown stuff in rad, could be dirt or rust moved around. if the oil is not contaminated, there might not be a problem. If this head gasket has a slight leak somehwere, allowing anti-freeze into the combustion chambers, that could be a cause of some white smoke. You could pull t-stat housing, start engine, and see if any exhaust bubbles are created. As mentioned, thread sealant on the 2 long bolts and any stud you removed out of the block should be used to prevent coolant leaks. With respect to the intake/exhaust manifolds, make sure mated surfaces are tru and clean, do not tighten stud nuts or the 2 bolts too tight, check after a few heat cycles. those 2 long bolts may have some antifreeze leakage being sucked in the combustion chamber possibly causing some problems....good luck, keep us posted Quote
szebban Posted February 11, 2014 Author Report Posted February 11, 2014 Just as i thought then i havent used any thread sealant on any of the studs, rookie mistake i guess. So can i just take them out one at the time put some thread sealant on it put it back and go for the next one ? Or should i take intake/exhaust mainfolds of again and start all over? If i take it all of again should i change the gaskets ? I will try to remove t-stat housing and check for exhaust bubbels next time iam in the garage, and i will put thread sealant on the bolts. And just go from there to see what happens! Quote
Don Coatney Posted February 11, 2014 Report Posted February 11, 2014 One at a time will work as long as there is enough room to remove the studs. Before you remove the thermostat I suggest you do two things. First a compression check should be done and then look inside the radiator with the cap removed and the engine running. If you see air bubbles you most likely have a problem. Quote
szebban Posted February 11, 2014 Author Report Posted February 11, 2014 Okey, then i go for that the one at a time thing. Compression check will be done and i have already checked for bubbels in radiator and there were none Quote
_shel_ny Posted February 11, 2014 Report Posted February 11, 2014 Lower the level of coolant before removing the bolts. Don't need to drain it all, just get it below the level of the bolts/studs to be removed. or coolant will be all over the floor. Quote

So this time I will drain it before. Thanks for the reminder ! Quote

Did you resolve this problem yet? if yes, please post your findings and resolution, if not, have you undertaken any corrective action, that did not resolve this problem....... Quote
szebban Posted February 19, 2014 Author Report Posted February 19, 2014 Did you resolve this problem yet? if yes, please post your findings and resolution, if not, have you undertaken any corrective action, that did not resolve this problem....... No i haven't had any time for that yet, i'am in school on one side of the country and my car is home on the other side. But this weekend i will get home and will try all those things you guys said and put some thered sealent on the bolts to see what happends. Quote
szebban Posted February 21, 2014 Author Report Posted February 21, 2014 So my friends the problem i solved! Changed the bolts to the original ones and put theread sealent on them and guess what no white smoke at all! Everything else was fine no bubbels in radiator, sparkplugs looks great and the oil was perfect. 2 Quote
