STEEL SEAL Head Gasket Sealer for 4 Cylinder Engines -

J'ai reçu vite le produit en bonne état, J'ai pas encore utilisé

I had a check engine light on with ABS light. Did the usual fixes - changed the fuel cap, reset the codes, etc. As the car was 100k plus miles, so replaced the spark plug. After a while the check engine light came back. The code check was P0304 - cylinder 4 misfire. It was a head gasket leak - bubbles in radiator and smell gas in coolant. Got the hydrocarbon tester from OReily's and it confirmed. I checked the engine oil cap but it didn't have any residue. I also removed a little engine oil to check if coolant had gone into engine. I didn't find any major trace of coolant. However, the coolant was going down and I had to fill up coolant once a week. This is when I decided to try the head gasket sealer. I removed the thermostat, filled the radiator with normal water. Followed the instructions mentioned in the pack. Once I added the sealer, kept engine running for 30mins. After this, I drove the vehicle for 15 - 20 mins on free way at 3000rpm. Left it to cool overnight. I had reset the engine codes and drove the car around. The check engine lights didn't come on. I have been driving the car for more than 3 months now. I had no issues with this - no check engine light, no gas smell in radiator / hydrocarbons. I can only upload one video, hence can't show the video where there are no bubbles.

I used 2 bottles. Others have had success but not me.. Maybe my head gasket is too far gone

Worked for about two hours. Initial start up and drove for a couple of hours and didn’t leak. Second drive about two days after and started leaking antifreeze again. Not a big leak to begin with. A pinhole leak on cylinder head. Used two bottles. Used two bottles on a 4 cylinder, 1800 cc engine.

It didn’t work
