Head gasket in a bottle

[TobiqueSlang]

With the amount of 1.8T cylinder 3 misfire threads in here and the amount of cracked heads on the AMB being the culprit, I'm just wondering if anyone has tried any pour in head gasket sealers? do any of them work? or are they pretty much guaranteed to wreck your motor?

Tried it as a temporary fix. Worked as advertised. Clicky click®

Chrisfix on YouTube did a test with head gasket fluid and it lasted a year or two before it gave out. So like old man said for a temp fix

Works as long as you're willing to basically throw the motor out after. I would say don't use it and just replace the head gasket. Idk about the 1.8T motor but I've done a couple of 4cyl and they're really not that difficult.

Blown head gaskets are a rarity on the 1.8T. The issue is with the AMB head cracking between the valves. 1/2 of a bottle of the Bars 1111 Head Gasket Fix will absolutely fix the problem. I used it successfully to seal my cracked AMB head. After I ultimately replaced the head I sent the cracked one to Kevin C for dissection. Kevin cross-sectioned the head to observe the internal cracks. There were no signs whatsoever of clogging in the head cooling galleries.

Good to know Old Guy. For if there is an need for a urgent quick fix to delay the inevitable.

That’s impressive

I would suggest getting this diagnosed properly before throwing some chemicals into the cooling system that could potentially create a bigger problem than you have. For all you know you have a issue with coil wiring, coils, plugs, injectors or injector wiring.

Agreed. Just run a block gas test to confirm or eliminate a cracked head diagnosis.

oh, I've gone over everything. I've already replaced and inspected everything that could cause a misfire and really the only thing left is a head gasket or a cracked head.

I saw it, the sealer didn't even fail eventually he was just done with the car but like anything on youtube I took it with a grain of salt because you never know. there's a big difference between a 4cyl german motor and a 6cyl jag.

this is really why I was asking, especially if it's a cracked head. I've had a cyl3 misfire as long as I've owned the car pretty much but it's rare that it happens, usually only after the motor has been cycled a few times(short trips to a few places) never had a problem on the highway or driving distances. car doesn't smoke, doesn't seem to be burning off anything but the coolant always gets low and I've got to bleed the system once every week or so.
It's not likely I'll be able to get a new head for it any time soon since it's near impossible to find parts for a B6 in maritime Canada, so until I have the time and money to get right into it and find one somewhere else and COVID finally lets up.

I just wanted some second opinions on whether this could work in the meantime or if it was going to completely trash my cooling system.

As mentioned above, a block gas test can confirm exhaust gas in the cooling system. It is a simple test to perform.

Is the misfire present only at cold start and during winter conditions??

you don't need to replace the head with one from a B6, theres tons of options for heads from B5s, Golfs, Jettas, Passats

1.8T's in general are hard to come by. There's on scrap yard in the province and they have 2 B6's and a passat and they're both pretty picked over. a head isn't the only thing on my wish list, Ive been trying to find a set of front doors for over a year too.

only shows up after 3 or 4 cycles. never on cold start. example being, start up, leave work, stop at gas station, start up, go to grocery store, start up, head to the liquor store, start up, misfire limp it home.

once it's had time to properly cool down starts up again no problem. it's the only time it happens. I can drive it for hours without a problem, it's just once it's been cycled a few times in a short period that it happens.

Sounds like leaking injectors to me or a bad pressure regulator,rather than a cracked cylinder head.

as far as I can tell the injectors are fine, I haven't got into the regulator but I will now. I'm going to test it properly before I put anything in it regardless but the plan is to replace the injectors, fuel filter and N80 this spring anyway as well as all the vacuum check valves.

this car needs a million little odds and ends as well as just some general maintenance parts that have never been changed. it wasn't very well taken care of by the guy I bought it off so it's been a bit of an endeavour. it's due for a timing belt just about so the plan is to do everything while I have the front pulled off it. radiator, j plug, water pump, injectors, seats, check valves, N80. basically everything thats never been changed or that I can change for peace of mind.

the biggest hang up is getting a set of front doors, It can't pass a safety here because they're a little rusty so there's no sense in doing anything if I can't get those swapped.

Bar’s leak got me by for a season before a head replacement. Burning coolant smell on startup and a wet piston was a dead giveaway.
