A leading mechanic has warned diesel owners should never use a common store-bought product.
Motoring expert Scotty Kilmer said motorists would “waste money” if they tried head gasket sealers despite claims the solution works.
Mr Kilmer confirmed diesel owners were “never” going to seal a damaged engine by using the solution because of how the tools work.
He made the admission on his YouTube channel as he urged owners to not “waste their time”.
He said: “Don’t waste your money on sealers. It’s a diesel engine. The compression in a diesel engine is so much more than a gasoline engine.

“I have never ever seen a sealer stop a leak on that immense pressure. Diesel engines don’t have an ignition system. They don’t have a spark that fires to blow the gasoline.
“They go by diesel compression. There’s so much compression in the engine that when it squashes it, it ignites from the pressure and puts out the power.
“They are so much more pressure, no head gasket sealers going to fix it, don’t even waste your time.
“You’re just going to be p***ing in the wind attempting to seal a diesel engine with any kind of little sealer. It won’t work. I can guarantee you. I have never ever seen a sealer seal a diesel engine. There’s just too much pressure inside them.”

The fluid solution supposedly re-seals leaks on a damaged head gasket which could save owners expensive repairs.
WhoCanFixMyCar claims that leaks should be “dealt with promptly” and that the solution acts as a “stop-gap solution” to prevent further damage.
They claim the sealer will work but stressed it was likely to be a temporary fix.
In some cases, the part will be damaged beyond repair which will require road users to visit their local garage.
Mr Kilmer stressed motorists with issues were likely to need new parts which could be costly.
He added: “You’re going to have to take the hat off and put a head gasket in and it’s expensive… If you’re willing to get down and dirty it can be taken apart and put back together again
“Just realise if you have a guy that’s a mechanic who works on diesel engines all the time he is going to charge you a fortune.
“Diesel mechanics are super expensive. It’s just the nature of the game.”
