    With those kind of problems you are not going to repair it...either replace the engine or scrap the car.

If the oil pump does not work, the entire engine will lock up and be totally useless. You will need to do a complete rebuild of the engine, including main bearings and rod bearings. Sometimes it is easier to buy a rebuilt engine, in the area of $1800.00. Rebuilding will cost 800.00 plus 15 hours lablr.

The van has a weird cooling issue. water pump and timing belt have been repaced


if you have a blown head gasket in the engine this could cause the pressure to increase on the cooling system., A radiator specialist can put a radiator cap on the radiator that has a pressure guage attached to it to test this . A compression test on the engine would also rule out or confirm a head gasket or warped or cracked engine head. Coolant may be getting into cylinder 3 via a blown head gasket and cause a mis fire or ignition failure in the cyclinder of the engine. You may see steam coming out exhaust pipe also !

Mis fire on cyclinder one and overheating for an 2005 Chevrolet equinox


You are describing the classic symptoms of a blown head gasket from the cylinder into the water jacket. This causes loss of compression in the affected cylinder and also injects hot gases into the cooling jacket resulting in overpressure and overheating of the coolant. Perform a compression check of all cylinders and if any are appreciably lower than the others, you are looking at some major engine work.

I have a 2002 v6 mustang. I installed a used 2002 v6 engine 3 weeks ago because my spark plug threads tore on my original. NOW i have 4 cyclinders misfireing, tranny shifts late or after i let off the...


its a well known cause that if the motor is running really bad the tranny will **** or act bad your gonna have to find the problem with the miss firing cyclinders and fix it doing this make fix your tranny problems you can clear most computer codes by unhooking the battery for about 10 min and then start it and see if the engine light comes back on that will give you a new set of codes you will have to have them read and fix what they are.

Smoking after start up


If it's the org. engine it will has over 160,000 miles on it.
It's normal to has valve stem seal/oil seal on the head to leak oil into the cyclinder on high mileage engine.

The smoke you see is the motor oil drop from the valve stem seals. The oil drops land on the top of the cyclinders and it create black smoke at start up.

The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.


The correct fix is to wait until it's time for a head gasket replacement and let the professional CRC/service the head.

Complete head service is the only method to stop this internal oil drip problem.
