HEADGASKET BLOWN....or has it?!?!?

[Piggy]

so drove 50mile to a funeral today...on/off boost...some A roads, some motorway...85degrees non stop

got to the town and it started to play up...temp moved up to 110/115 few times, both fans on, then down again, then up again.
and the heaters went cold...

I though headgasket but hoped for a airlock

nursed it round...got to an old mates and let it cool and checked for air...was a bit...bit of pressure too...so topped up, rebled...

took for spin and as soon as on boost the temp rose rapidly....
off boost it slowly dropped.

went back to me mates for tea ready for a slooooow journey home...possibly via Green Flag.

Started to gee meself up for a weekend head rebuild...let my OCD go wild on some valve seats etc...but

Just got home...all is well?!

Sat at 85degrees, heaters are toasty, last 10min of journey I got onto some serious boosting and its fine!?!?

duno what to think now?!

[Pompey306mark]

Mine does the same. Sometimes it does it sometimes it doesn't.

I think it's a head gasket.

[Piggy]

as far as Im aware once a head gaskets gone...its gone...


I HATE temp repairs like radweld...but I just need it to last a couple months till I have the 2.1 cossack done then I was going to rebuild it for the 106 anyway...

so not sure to try a headgasket weld fluid repair fluid?!?

[londondan86]

Shouldn't really of let it get that hot these engines can warp the heads if allowed to go much passed 100*. Either way, check the usual signs, mayo in oil/water, pressurised top rad pipe, etc.

[spike2002]

Mine has gone today stop light on and temp light is on but sits at 90 doesn't go above but can see the bubbles between the head and block

[Piggy]

got no bubbling...

no mayo, no oil in water.

till the journey home I assumed it was between cylinder and coolant gallery as it got hot on boost?!

but its fine now?!

[devils_fuel]

Piggy - i would rebleed the system as per normal using the bleeder valves etc & put cap on and run for a bit, fans etc. After a few mins Undo cap slowly to release the pressure then leave the cap off over night to let the extra little bit of air surface, due to the design little pockets off air meet up and create a bigger air pocket from my understanding.

Next day undo the bleed valve on the radiator just slightly for water to escape from and redo up tight & top up the expansion bottle if required and the put the rad cap back on

[Piggy]

thats my thinking...worth trying before I rip off me head and tear out my hair!

[Pompey306mark]

Been there many times, mine only goes to just over 90, but I just wack the blowers on and it comes down.
Have got bored of rebleeding the system over the past few months.

[spike2002]

Any one else had the stop light and temp light come on? It doesn't go above 90

[Piggy]

nope...
mine got to 110 and fans kicked in and it holds then drops...

[CJ_Derv]

Yeahh go for it whip the head of and waste a weekend please!!

or do what im going to do and change a dicky stat after testing it to reveal its shagged

[Piggy]

you rekon its a stat issue?!

[CJ_Derv]

Check it take 10 mins mine is only opening now and then and hiking up to 95* when never went over 85* and can see stat opening and then not opening even past boiling point in the pan

I could have sworn youd said you were a peugeot techy one one of your original threads, as i asked a fellow member and they agreed theyd seen this. Id have thought youd have been a bit more knowledgeable but your threads say otherwise just sayin like

Yeah my early days....but I always question my own knowledge...been a few years since its been my main job....I got very ill with it, boss, injured back etc etc, so have to take things easier now.
Plus he always questioned everything I did....and got angry with me a lot. Best one was when I opened up a head gasket set, and he said I wasnt ready to do it as the headgasket should be fitted as soon as its out the wrapper...or it will go off!?
Plus what happened last year, its given my self esteme a thrashing
Always willing to listen and learn.

I had happily(!) diagnosed it as a head gasket fail last night...all the symptoms...but the drive home completely threw me...hence the thread.

Forgive me if i'm wrong, but judging by your username you're 26?! You work from a young age as a Peugeot tech?!

[CJ_Derv]

Ahh i see, JJ has got a point tbh how old are you as going off your name im actually younger than you and am a plumber/assistant manager of olumbing company and self tought with cars, i just find it easy to think mechanically and tbh do agree asking is key to knowledge

And tbh i actually thought you are the guy who tried giving me shit from yorkshire ways with a black 306 2.1 which he claimed had a hybrid td04 n he was talkin out of his arse

Injured back jesus i do that every week deadlifting over 250kg in the gym then go home and throw a xud block on ma workbench everynow and then lol

[Piggy]

Nope, not yorkshire lad!

I started at 16 with a pug specialist, general cars too...left when i was 20 though.

I fell down a flight of stairs when I was 9 then I was a passenger in a big car accident when I was 14.

I often got stuck bent over working on a car. Now spend time each morning stretching to just get up...same during day, same at night so I can sleep. Starting to get me down but I do what I can.

I find it easy to think mechanically too...but never mind asking if peeps dont mind being asked

[CJ_Derv]

Ahh thats a shitter with the back injuries, if it wasnt for me being a big fucker from gym could have been a different outcome in my car crash last year

[Piggy]

yeh Im lanky git...difficult cycle...i weigh nothing and have back issues and a SUPER fast metab'....desperate to put weight on but its not easy. Powders have helped but not massively. trying a lot of resistance work to avoid strain, just very slow progress

I have put on 1/2 stone in last year....so now am about 9stone6!!!

Can be an advantage...like when gocarting...but it dont help much else!

---

Just gone out to the car...
its been 12hours since its been driven...
took rad cap off and there was still pressure in the coolant system....I would have thought thats a nail in the coffin for the headgasket....

[Mattcheese31]

sounds like HG to me . .

[Ricky]

If there's pressure after 12 hours I would say HG.

[Piggy]

head is coming off as I type...now I got three non working engines! bloody ek

[Piggy]

---

nothing obvious...just all bit old....

dont think this was helping though.....very, very close to failure

[CJ_Derv]

That pipe could be the cause of extra temp as mines been doing it as is quite close re-routing it at some point soon

[Piggy]

yeah but I dont think its only just been like that...and for the system to stay pressurised for 13/14hrs is quite something!

is crap down the back...I cant see what route it even should take!

[Anton]

Mate it would have been fine, i did 20k on worse symptoms than yours.

Your 2.1 ing, would have just got on with that.

[Piggy]

I know but I need a reliable daily...

plus it would need doing anyway as I was guna rebuild the head for me wifeys 106nad/xudt next project

[Anton]

Mine was reliable, 7 months 20K.

Would have just kept and used the other engine that your trying to sell....

[Piggy]

Aye but need the cash from other engine sale...its also drained for transport and me current blow engine has had new oil and gearbox oil and clutch recently...

its annoying I know...I nearly ordered some Kseal but couldnt bring myself to do it!
