Anyone ever tried any of these products?

The MGF is showing signs cream, again, two years after a brand new engine. I can't replace it just yet, its just started to go, the very early signs.

What d'you think?

I think your just making it up, everyone knows the k series doesn't really have any problems

I used kseal on Honda crv for over 2 years follow the instructions though

K Seal is good but can bung up waterways, heater matrix etc. Before you go down that route are you sure it's not just condenation? cold weather and too many cold starts?

We used a brand new head, with the aluminium locating dowels and uprated gasket. I've been singing it's praises ever since, a wonderful revvy engine, was even going to replace it with a 111s in the summer. Not now. The converted has become unconverted.

OP are you sure it is head gasket failure? Short journeys, especially in winter, can cause creamy mayonnaise type residue to build up.

Well, I was offshore and it had only been used for short trips by the misses.
The car overheated, it's the second time it's overheated recently. Although this could be down to a dodgy expansion tank cap.

You've got me thinking now. After it overheated I took off and replaced the exp cap and it ran fine. Didn't heat up on the returning journey. I'll give it an oil change, buy a new exp cap and see how this goes down.

Thanks for that, should really be exploring all options before writing it off.

Its a common thing to happen with the K series that the oil filler cap gets a bit of condensation over short journeys in cold weather. It gives the appearance of being HGF but its a minute amount of mayo compared to how much you get when the hgf goes.

Got a chance to look at the car, the oil needs replaced, there's a slight hint of cream to it, not much though. There doesn't seem to be any bubbling from the expansion tank.

We had a big discussion about what to do with the car. Spending a lot of money on it is a no. She's had enough money spent on her.

So options...
1) Buy a car to tide us over to until later in the year, thinking Porsche 944 S2 cab.
2) Spend money on the integrale and reinstate it early.
3) Car share with one car.
4) Bodge the MGF abd see what happens.

Well I did a lot of research on K-seal, it has varied but mainly positive reviews.
So, for less than £40 I managed to buy some K-seal, New Expansion cap, Oil and filter.

For experimental purposes and nothing to lose I'm going down this road and see how long the old girl runs for.

HG shouldn't mean new engine. And is often a sign something else isn't 100% right. Trying to cover it up is only likely to either delay the inevitable or make it worse.

Sorting it properly and letting it warm up gradually when you use it are you best means.

It needed a new engine a few years ago, but that was due to not only HGF but the bottom end being badly worn, drinking oil and spitting out the exhaust, also sounding like a diesel.

I took it into our mechanics (whom I trust totally) the first time it overheated last month. He ran it for two hours and it never showed any signs of over heating or faults. It's had a new radiator too.
If there is another fault we cant find it! I can't be throwing any more cash at her. She's had thousands thrown at her over the past few years. May be something as simple as the expansion tank cap???

I always warm it up before driving, I can't guarantee the misses doing that too. I doubt it very much, she's probably moving before the engine makes its first rotation, doing her lippy in the mirror and halfway to work before its at optimum operating temperature.

I posted the following comments on the earlier question on PH.

I have used this product many times it is excellent. No connection with the maker.

It got me out of trouble with several classic cars from time to time as my stable altered.

However like all these products it obviously cannot produce the same result as renewing the offending leaking part.
definitely works. I drove several thousand miles in these cars after
However it worked for me. I could not get the parts easily and this product treatment over time and it even kept antifreeze in the motor.

I thoroughly recommend the product.

However.

No sealer can replace damaged or missing parts. Classic cars are generally much less stressed than modern high performance engines, Despite owning over 40 "A" series variants over the years I have NEVER seem a head gasket fail on a BMC A series. They were very understressed engines.

Modern engines like the K series are very much less forgiving. The crossbolts fail on the K series as do the head gaskets. Sealer cannot cure either. If you have a failed K series head gasket it NEEDS replacing otherwise you will end up replacing the engine itself. K seal may offer a short term breathing space but it CANNOT be a cure. Good luck with your difficulty.

Well, I got myself in gear and looked at the car sitting dormant on the drive, drained the oil. Surprisingly it looked ok. Black, gundgy but not creamy.

My misses (who's car it really is.. honest) is now afraid of driving it with all the stories of the K series, even the 85 year old lollypop man wouldn't risk running a Rover K-series.

So after changing the oil and filter I decided to put the super solution into the system and see if it could magically stop the coolant from disappearing. So far it's all good.


But... as was said to me already in the thread, which I tried to ignore as I'm ever the pessimist ... maybe the cylinder head is ok. I'm now thinking that yes, there was a coolant issue but not going into the cylinders. She has had the car for the last week while i've been away working very hard entertaining people in the pubs in Germany and so far so good.

Beware... as was said. The filler cap and dipstick in the boot of the MGF can get water contamination and non of the rest of the oil shows any sign of mixing.

Really. The oil was not cream.

Fingers crossed. The little snotter will live to fight another day.

I know vroom, but I'm halfway through doing the integrale head, and the MGF had a brand new engine a couple of years ago.
Its make or break for the insolent girl. All the money thrown at her and she still has no respect for us.

HGF doesn't nescessarily contaminate the oil.
