Some sort of head gasket sealent? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I replaced my head gasket last year, and pretty much ever since I've always slowly accumulated coolant stains down the side of the block. It will take a few months to get the stains, and the run evenly along the side of the block (ie, if its leaking, its leaking evenly along the exhaust side).

The coolant level isn't dropping, it'll drop from max to a few mm under max after about 3 months at most. So all in all I wouldn't put more than a cup-full in.

The engine runs beautifully, smooth, quiet, heaps of power, the oil is clean, the cooling system has no leaks and fuel consumption is in the high 11s which is excellent.

Its fairly obvious that the gasket hasn't blown, and that it is merely weeping under my stress from my right foot. What I want to do it but some sor tof glue along the side of the gasket between the head and the block to stop this weeping.

Is there such a thing?

If not Rollin? Are you busy, cause we may be changing my head gasket hahahah!

Never! put glue on a head gasket! :)
It causes far too much trouble when it comes to take it off.
If I was you, next time I had the head off, I'd check how level the block deck is, sounds like you might need to get the block and/or head skimmed. That should fix the problem.

How would I ge the block skimmed? Does that mean the block needs to come out?

Copper spray.

Paint both sides of the gasket with this.

Try retentioning head bolts.Were head bolts replaced when new head gasget was replaced??? Was thread in head clean to allow correct tension???

Ford did the repair under warrenty, I don't personally think the gasket is bad, I think the seal between the gasket and the allow/iron is not good enough to hold it back.

The repair was probably dodgy.

Can I retension the head?

I use hylomar. Someone told me to use this and run the engine to just get it warm (not operating temp) without coolant to seal it and i have never had a head leak.

placed on the outside of the engine block over the head and block join? while its warm. why no coolant? mine won't leak just if i give it 5100rpm for a while shell develop a few drops.

The block would have to come out, yes.
An ED shouldn't theoretically have a warped block, it was mainly a casting problem with early EAs, but it is possible.
Hehe of course you could deck it while you're at it and raise the compression a bit, if you cared enough

It nearly impossible to seal a leak from the outside, ever tried to fix a leaky rain water tank from the outside?

If it is using as little water as you say, and the car is running OK, I wouldn't bother about it. The other options are not worth the cost.
