Last week someone told me about a friend who had his car at an large auto repair shop—one that is part of a chain that sells tires, auto parts and accessories, and repairs cars. He had a 1998 Ford Taurus with a little over 125,000 miles on the odometer. He brought the car into the shop because the check engine light was on. He left the car there and later received a call with the bad news.
He was notified that he had a blown head gasket, needed spark plugs, spark plug wires, a radiator and hoses, fan belt and an idler pulley. He was told the total cost of the repairs would be $5,299. I spoke to his friend and asked him to have this person contact me so I could help him. He contacted me and gave me the information about the car. I asked him if it would be okay if I helped him with the situation. He told me it was okay and was very pleased to have me there to help him.
I called the auto repair facility myself and asked what was going on with the vehicle. I was informed about all the needed repairs, and I asked some questions. First I asked “how did you determine that the head gasket was blown?” Their reply was “We did a block check where air is taken off the top of the radiator and checked for signs of exhaust.” They told me that the vehicle had failed the block test. Next I asked them if they did a compression test on the motor, and if they did what the results were. Their answer was that they did do a compression test, but their technician had not written the results down. This is where a big red flag went up. If any mechanic is going to go through the process of doing a compression test, they are going to write down the results.
I contacted Naoya T. who owns the car in question, and asked him some questions about the car. Was it overheating? No, he answered. Was there any steam or smoke coming out of the tail pipe? Again, no. But the check engine was on? Yes.
I was notified by the shop it was at that the code from the engine computer was for one of the cylinders not firing right. It caused what is called a misfire code. That happens when one of the cylinders on the engine is not developing as much power as the others. It sets a code for whatever cylinder is not working properly. This one happened to be cylinder #3.
I had him bring the car to me personally so I could check it out. What I found was that the check engine light was on and the engine lacked power. I also found that the engine coolant was very dirty and low. The fan belt was normally cracked and the idler pulley was slightly wobbling.
I removed all the spark plugs for inspection and found no signs of engine coolant on any of them. I also inspected the spark plug wires to see if there were any burn marks where they might be leaking or arcing. They looked okay to me, but they looked to be the original wires. I had asked Naoya to supply me with a set of spark plugs and wires so I could replace them, but the chain store gave him the wrong parts. The spark plug wires did not match the original wires, and I didn’t want to take a chance with the spark plugs if they supplied the wrong wires. So I called up Naoya and asked him if it was okay if I picked up the parts myself so I could be sure we had the right ones which he gave me authorization to do.
Having gotten the correct parts, I installed the new parts and tested the car. It still ran badly and had the misfire code. I replaced one more part called the Coil Pack and the engine ran smoothly. I reset the check engine light and test drove the car. Everything seemed okay.
The things that you need to check if someone tells you that your car has a blown head gasket is; 1) is it running hot? Most of the time a motor with a blown head gasket will run hot and boil over. 2) When you check the engine oil, does it look like chocolate milk? When the coolant mixes with the oil in the engine crankcase, it really looks like foamy chocolate milk.
3) If you remove the oil filler cap, does it also look like a brown goop is on the bottom of the cap? The moisture in the oil will collect on the bottom of the oil filler cap. When water and dirty oil mix, they make a brown goop.
4) Is there a large quantity of sickeningly sweet smelling steam coming out of the exhaust? Engine coolant releases this type of smell from the exhaust when it is burnt in the engine.
If you could answer yes to more than two or more of these questions, then there is a great possibility that your car has a blown head gasket. Naoya’s car had none of these symptoms. I replaced the parts needed on his vehicle for $120.00 retail. I also fixed his ignition switch by replacing a worn out key for an additional $22.00. His whole total was $142.00. If he had taken his car to a reputable shop they would have charged him approx 4 hours of labor. Figuring the labor at $95.00 per hour, that’s $380.00 + 120.00, for a total of $500.00. His whole total savings would have been $4799.00. So if a shop gives you an outlandish estimate like this one, get a second opinion.
