Head gasket problems can cause leakage of antifreeze into the exhaust through the cylinders and low antifreeze levels can cause an overheat problem due to a leaky head gasket.

A leaky water pump can do the same thing except you'll see a puddle of antifreeze from the o-ring not sealing right.

Blown head gasket seal can help with minor defects in the head gasket seal but not major leaks.

It may be worth the cost to try a head gasket seal solution before replacing the head gasket which is a major procedure.

More likely a cracked head than a head gasket. You can get a head gasket test kit that will test for a leak of CO2 through the radiator.

Before replacing head gasket put a pressure test on the coolant system and look for a leak around the intake manifold gaskets.These gaskets are prone for leaking and allowing coolant into the oil.

How do i repair a blown head gasket on my 1992 cadillac deville V8 4.9L


The correct way is to remove the head(s) have the head(s) checked for warpage repair as necessary then clean everything good and replace the head gaskets. There are some places that advertise a product that is suppose to seal a head gasket leak but remember if it seals the headgasket leak it may stop up your radiator, also it will just be a temporary repair

If the dealer put an egr cooler on and didnt replace oil cooler, it can blow out egr cooler again , restriced oil cooler causes egr cooler to blow out , which in turn can cause overheat and blown headgasket also, if you are seeing white smoke now it is possible for the egr to be blown out again as wel as the oil ooler and/or headgasket

Stage one of a blown head gasket is a pin hole leak. As time goes by the hole(s) get bigger.
I will start traking the coolant lost and oil lose.
From the time you stop your engine to the next morning,there can be slow leakage between the coolant passage and the cyclinder end of the head gasket.
This is one possiblilty of lots of white smoke in AM.
Small amount is normal but large amount of smoke is a call for a professional check up.
To pin point a blowing headgasket you will need
1)coolant system compression tester
or
2)chemical reaction test for combustion test gas
If it's the org. engine from 1997,with over 110,000 then blowning headgasket is a good possiblity.
Drive it to the shop and let the pro to do the coolant pressure test and combustion gas test.
A full head gasket job with head re-surface (if it can be re-use) is worth it.
Shop around on well estiblished independent shops.
Fix the blown head gasket at the first stage of failure can safe you thousand on a head replacement.

Pajero 1989,too much smoke durong first start


Is it white,black or blue smoke?
If it's the org. engine it will has over 200,000 miles on it.

It's normal to has the valve stem seal/oil seal on the head to leak oil into the cyclinder.

The smoke you see is the motor oil drop from the seals. It 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 to service the head.

Complete head service is the only method to stop this internal oil drip problem.
I will monitor the oil and coolant level.
White smoke AFTER warm up is the first sign of blown headgasket.
