Would a blown head gasket show up on a diagnostics for a sticker?

A blown head gasket will not show up on a diagnostics test but can show itself through the readings of several different sensors. The sensors will tell if anything is wrong with the airflow, coolant flow, or fuel flow of the engine.


If your head gasket has gone on your A140 would the dipstick show clear oil on it or would it be a different colour?

When oil and water are combined in the engine it will form a white frothy mixture which will be evident on the dipstick. Definate indicator of a blown head-gasket

I have 1991 Mitsubishi lancer i have oil leak at back of motor my repairer said i have leaking head gasket i have no overheating problems or water problems what do you think?

Hi A head gasket can leak oil without causing overheating problems. If the gasket has blown between an oil gallery and the outer edge of the head it will show as the problem that you are having. best wishes


Is it a good idea to re-torque head bolts on an old engine?

Re-torquing head bolts can prevent head gasket failure. Some manufacturers have issued technical service bulletins describing the procedure. (See Saab example here: http://www.saabnet.com/tsn/members/gallery.html?memberID=112&do=show&id=369 ) Reducing the tension on bolts one at a time (But not all the way.), then tightening in sequence is often done, particularly on engines with aluminum heads. Once the gasket has failed re-torquing is less likely to stop the leak. No. Torque specs are calculated on a new head gasket. If you are experiencing a leak in a head gasket, you would be safe to assume that the gasket has already burned a hole in the gasket.


How do you replace the head gasket located on a 1996 Honda Civic?

It is a big job requiring lots of work. If you want to tackle it go to a parts store and get a manual on your car and it should show you how. Replacing the head gasket on any vehicle is a long and complicated process, however if you wish to see basic step-by-step instructions go to the related question on the right side of the page "How do you replace a head gasket?"


How do you change a head gasket step by step on a fiat punto?

Punto head gasket change is quite an easy job to do. It is almost impossible to give step by step instructions on these pages. The best that I could suggest, is for you to get a Haynes manual for the Punto this will show the exact procedure to follow.


What is the Best head gasket sealer for a 1993 Saturn SC2?

The following is true for ANY head gasket failure. The "best" head gasket sealer would be to remove the head, have it machined and put on a new head gasket. Trust me; head gasket sealer won't do much good other than to lighten your wallet a bit. There are always a few companies out there that will try to sell you something to solve your problem, even though it won't solve your problem. The reasons the gasket sealer will not work are very simple: 1. the pressure inside the combustion chamber is so great that the sealing material is constantly being pushed away from the leak. 2. the temperature change causes expansion and contraction of the leak, so even if the sealing material COULD seal the leak, it would immediately break loose next time the engine heats up. 3. the high temperature of the combustion gasses cause the head gasket to continue to deteriorate and any sealing material that has built up will be immediately destroyed. History of a typical head gasket failure. The head gasket failed when the engine overheated. It may not show up immediately, but that's when the failure began. If an engine is allowed to run when the coolant level is too low, the head will warp slightly. It isn't enough to notice when you look at it, but if the head gasket failed, the head is warped. The head gasket depends on even pressure between the head and the engine block. The pressure contains the high temperature exhaust gasses that are pushing against the head gasket every time the cylinder fires. When the head warps slightly, those exhaust gasses find a pinhole to sneak past. The hot gasses under high pressure then start to erode the gasket material and the head gasket will fail completely any time within a few thousand miles. There really is only one way to repair it... sorry to be the bearer of bad news. BTW, radiator sealer actually may work, but it's generally not considered to be a good "long term" solution.

How do you check if head gasket has gone?

Pull out the oil dipstick, if it has a chocolate milk-like consistency to it that would show that coolant has leaked into your oil and would be a pretty good indication that your head gasket has gone. Other symptoms are white smoke from the exhaust, loosing coolant with no apparent leak, a white foamy substance on the underside of the oil fill cap, & air bubbles escaping from the radiator with the cap off engine running. A compression test will verify this.
