BMW 318i, 1998

Having been told the repair cost for a blown head gasket for my 1998 BMW E46 was going to be £400, I left the car for 2 weeks before reading about Steel Seal on a BMW forum. I was very sceptical about this product initially

but I decide to try it out at £25 with a money back guarantee it was a no brainer really. At best case scenario it will work, saving a repair bill of £400, worse case, a full refund with a repair bill to pay. The car started to lose water initially and then the heavy smoke from the exhaust with the inevitable overheating led to the head gasket failure. Upon receipt of Steel Seal I followed the instructions exactly as stated. I then started the car with heater and blower settings to maximum as per instructions. The exhaust smoke although initially thick, this started to dissipate but the temperature gauge needle started to go into the red zone at the 2 o’clock position at which point I switched off ignition as per instructions and left the car somewhat disappointed overnight. On day 2 I started the car and this time the temperature gauge needle stayed at the normal 12 o’clock position, there was minimal smoke from the exhaust, however, I had no hot air from the vents. With the needle at normal I decided to drive the car. Within 5 minutes the temperature needle went into the red zone again. I parked up and left the car overnight. On the day 3 I checked the coolant level and topped up and started the car, the temperature needle began to creep into the red zone up to 1 o’clock position but then backed down to 12 o’clock normal position where it remained static, there was no smoke from the exhaust and blistering hot air from the vents. I left the car running for about 40 minutes and the needle remained static at 12 o’clock, I had hot air and no exhaust smoke but the radiator light came on, so I switched off and let the car completely cool down overnight. On day 4 I topped up coolant and switched on, let the car run and after 30 minutes no radiator light on, full hot air blowing, no exhaust smoke and normal operating temperature. At this point I decide to drive the car for 10 miles at 40mph at around 2000-3000rpm. Dare I say, the car actually felt smoother, it appeared to have gained some loss compression. Upon returning home I checked the engine bay for any leaks and there was no sign of any. So far Steel Seal seems to have worked for me and I remain optimistic and positive it will continue to do so. In submitting my review I am not endorsing Steel Seal in any way, I am merely stating my experience of having used it, which, is a very positive one so far. What I would say to anyone intending on using Steel Seal is to follow the instructions exactly as stated ensuring if administered via expansion reservoir it is actually circulating through the engine block/cylinder head and not just sitting in the reservoir and above all be patient. After all, it took 4 days before Steel Seal worked for me but it has so far worked.
