95 olds 88 after an engine rebuild cylinders one and six fill with coolant. what else will cause this other than a busted head?

The heater before fill won't be the problem
The problem of white smoke is that water is getting into the cylinders so the head will have to come of and checked for ?racks or gasket failure to a cracked cylinder liner

engine got probably way too too hot could blowed head gasket cracked cylinder head.depends on how low coolant got if coolant level got close empty probably got engine damage.if coolant didnt get too low wait until engine cool down try cranking it.engine could have got so hot burned out ignition module.

Its possible you hydro-locked a cylinder with coolant which would have bent a connecting rod. When a cylinder gets liquid in it, the liquid will not compress so something has to give.
The head gasket could be leaking to cause the leak into the cylinder.
Hydro lock could also bend a valve.

if it's a V6 then you prob have intake gskts/head gskts leaking coolant to cylinder and causing it to hydro lock, filling cylinder with coolant and filling radiator with cylinder pressure causing coolant to blow out of radiator and reduces your cooling of engine.....see a mechanic looking at a big repair bill or engine swap

Six IN LINE - 6L

Fig.: Cylinder head torque sequence - 6 -cylinder engine

Cylinder head torquing should proceed in three steps and in the prescribed order. Tighten them first to 50-55 ft. lbs. (65-71 Nm), then give them a second tightening to 60-65 ft. lbs. (78-84 Nm). The final step is to 70-75 ft. lbs. (91-97 Nm), at which they should remain undisturbed.


Six IN V - 6V

Tighten the head, according to the illustrated sequence in three progressive steps. Tighten the bolts to 50-55 ft. lbs. (68-74 Nm), then 60-65 ft. lbs. (81-88 Nm) and finally to 75 ft. lbs. (102 Nm).


Hope this helps (remember to rate and commene this answer).

Hello, my engine light was on for a VERY LONG time and everytime I got it checked no one could tell me what the problem was because things always checked out fine. The "code" says its a loose gas cap or something, but it wasnt that. My 300M also was having A HARD TIME STARTING UP for about 8 months and leaking coolant for about a month. I finally found a mechanic who knew what he was doing; 1. Leaking Radiator 2. Coolant found in #2 or #3 cylinder. The cause of this was a busted HEAD GASKET. If your 300M has trouble starting and the Engine light stays on have a mechanic check your engine for a busted head gasket and see if all your cylinders are firing correctly. I had to pay $2600 for a new Head Gasket, Radiator and all new hoses plus labor. CRYING!!!!!!!!!!

I have a 2001 300M 130K - very well kept. Stuff happens...

hi, if you are changing the head gasket then it may be worth checking the water pump and thermostat as it could have been one of these that failed causing it to over heat and then blown the head gasket so check the water pump and thermostat once you have the cylinder head off.

You may need the head checking to see if it has been warped but this is unlikely on this make of vehicle.

Once you have done the gasket make sure that when you fill the coolant up you only trickle the water in to prevent any air lock as this will cause it to over heat again, check for any bleed screws on the coolant system to let the air out whilst filling the coolant up,

Its best you check in the workshop manual for these as their may not be none as it could be self bleed system.

It also worth checking if the head bolts need changing as they do stretch and can cause the gasket not to seal properly so replacing these may be a good idea.

Let me know how you get on or if you need further assistance ok.

ps what makes you think the head gasket has gone??

need to perform a coolant pressure test. fill the reservoir and after the engine cools down fill the radiator, next start the engine and wait till the coolant system builds pressure then turn off the engine and using a mirror and flash light look for a leak.check water pump, hoses,radiator tanks for cracks,intake gasket at the corners espesically at the back next to the trans.also pull the carpet back and check for coolant leaking from the heater core,and last remove the sparkplugs and check for leaking head gaskets.hope this helped.

The three most likely thing's cause overheating are faulty thermostat,electric fan or clogged radiator. Only at has been overheat so much it boils dry that it will cause engine trouble. Most common problem's are blown cylinder head gasket or a cracked cylinder head.
mixing coolant and water depends on where the gasket has blown or head is cracked. You will first need to check if it actually is overheating. The reason is. If the head is cracked or gasket blown then you can get a false boiling which is compresion from the cylinders blows through the crack in the head or gasket causing the coolant to blow out of the radiator cap.Fill the radiator to the top leave the cap off then start the engine.If the water blows out then you will need to remove the cylinder head check the gasket is ok. If its damaged replace if not get the head checked for crack's. If no water blow's when you start it check the thermostat is working properly. To check the thermostat put it a in a saucepan cover it with water bring the water to the boil. It should open before the water boil's but near boiling-point. If its ok then start the engine again leave it running until it boils and check the fan is running. If that's ok then its radiator problem. Their is no way to check if the radiator is ok you will need to get a new one. One last point. If the cylinder head or gasket are faulty it was caused by overheating so by just fixing the cylinder head problem is not a cure it will overheat again. Check the three things I mentioned at the begining and told you how to check them. Hope this help's. Cheer's

It sounds like you've got a crack in in the engine that's causing the coolant and oil to mix
