I hear a knocking sound when ever I start my engine


check oil level if low add oil ---if oil milky in color like chocolate milk possible internal damage from --blown head gasket-damaged head --the knock from engine usually means that damage to a piston rod has occurred [rod knock] and knock usually doesnt throw an engine code and usually fatal to engine will need a mechanic to diagnose how bad or what extent the noise is with engine

Gmc Safari van take a lot of water in radiator


3 possibilities:
1) Leaking (you should see coolant on the ground)
2) Going into your oil (sign of blown head gasket)
3) Going out your exhaust (sign of blown head gasket)
anyway you look at it, it's bad.

My 2006 ford explorer had an over hitting in the middle of no where so i have to manage it like that and drive it to the mechanical shop, is there any possiblity that it could affect the engine block


Once water gets into the piston bore of the block, it is very serious.
You could have a cracked block or a bent connecting rod....
Driving with a bent rod will turn very bad.
When they are replacing the head gaskets, they should check the length of piston travel to top dead center on each piston/cylinder.

If you have already replaced the head gasket and it's running rough, it could be caused by a bent push rod (connects the crankshaft to the bottom of the piston)
This would make it run rough and will fail sooner than you think.

I have a blown head gasket & my carkeeps overheating


You had better not drive it at all, get the head gasket replaced as soon as you can, if you drive it there will be water in the oil and your metal will not be lubricated in the engine, and it will lock up the motor completely. just look at your oil and it will be brown and fluffy like chocolate pudding. DONT drive it

Oil is milky.


Coolant is mixing with the oil, so it is turning milky.The most possible problem is an cracked cylinder head or head gasket.Check them and get it replaced before it damages the engine worsly.. Dain the oil and have it refilled after replacing then broken part.

This just happened to me today. I have a 2001 GMC JIMMY that has 116,000 miles on it. I wsa driving on highway and tried to quickly accelerate by punching the gas. Just after this the car started smoking...


was it white smoke
if it was you have a blown head gasket
what happens is that your anti-freeze dumped into your engine cylinders
major damage can occur.
like bent rods
do not restart your engine
check your anti-freeze see if it is low
and then check your oil and see if it is over filled
it may even start to look milky
If there is any sign of this you have blown the head gasket
Please write back and inform me of what you find
please give me feedback

2000 gmc jimmy, engine shut off while drving and would not restart. Checked fuel pump and pressure, found fuel filter to be clogged. Replaced fuel filter and started vehicle. Problem now is that vehicle...


No,it sounds like coolant burning inside the engine combustion chambers.This explains the sputtering and power loss.most likely cause is a blown head gasket or severe overheating.Check the condition of the oil and make sure their is not antifreeze in the oil.Also check the coolant level.this will help to identify an internal engine concern.Dont think the fuel filter going out is related though. Hope this information helps,

I have coolant on my oil dipstick is it intake or head gaskets


I would suspect a blown head gasket. STOP driving the vehicle immediately or serious engine damage will occur. Drain the oil and change the filter. The head itself may also be cracked. A compression test will determine if the head gasket is blown or the head is cracked. Take it to a trusted mechanic for diagnosis and repair if he is close by. If not have it towed in for repair.
