ATTENTION all Speedvision Headgasket users!

[59bhp]

Do you not understand what I am saying?

If the head is warped after the initial HG issue causing it to faill and then a Speedvision HG is fitted without the head checked/skimmed then obviously it will fail again.

But whatever, I've given my feedback. Let you know if I have any problems in the future.

i had coolent overflow problem and turned out the rad was the cause

but then why did it not fix it with the new headgasket? very strange that.

i actually had a overflow problem too, which i found the problem too along with turbodave but others didnt support it.

but my headgasket was absolutely fine

i do understand what your saying, and of course a pressurised coolant system can be cause by many things but in your first post you said that the people having trouble with them already had such issues as overflowing coolant which insinuated these were the causes and not the effects.

In the instances of the two speedvision gaskets i know off that failed both heads were skimmed and torqued to the correct settings

kelly, were all the headgaskets fitted in the same place?

Nope one buy a toyota mechanic, one buy a garage up here , and one buy a garage in southampton.

I dont think at all that the headbolts have been overtorqued, but then again u was all there and know our car better than us right?!EVEN if there was a chance that it had been I know of three good friends of mine who have the same trouble with the the same HG! maybe they all have duds too? dont think so....

i thought you said in your thread about this, that you spoke to your mechanic about the issues and he said that he over torqued the headbolts as he knew it was gonna get abuse

I got one in my engine at the minute, ive even reused it and it seems fine so far. I did notice that it looked to be leaking between 2 and 3 when i took it off the first time however. Ive done 4000 miles on my forged engine and it sees 1.5bar now daily on a td04

Yes but didnt u use sealant the second time round? which your advised not to use with this gasket.

our mechanic also uses sealant on all the gaskets he installs.,,,metal or non metals

I cant comment 100% on what he did with the headbolts as unlike other people i wasnt there nor do i know for sure, all i can say is that they can change headgaskets all the time, so i trust their work.

I understand your point dont get me wrong however i dont like the above comments with the words "was" .

Like i said, lets say that was my reason what about the other people who have issues?

No worries Sam, i just remember my friend sayin he used some and then some members sayin he shouldnt have.

I didnt mean this thread to turn into an argument! lol. :homer:

Thanks for all the info anyway. Il let yous know how i get on!

headbolts are brand new and it was slightly over torqued coz they knew the nature of the car :-s

thats what was posted in the other thread about speedvision gaskets.

any way were dithering away from the point in this thread.

some people say there good, others say they arent.

so pretty much the same as most products out there then lol

 

[Kelly]

Yeh but the guy said that after we returned and said we think the HG has gone again, tbh, i think he said it in the hope of it offering some reassurance. Plus it wasnt even the guy was did most of the work it was his collegue.

Like i said above if that was the case then it would only be us with problems.

 

[Dave.]

Exactly what I remember reading Ricky ^

Also, we might aswell have been there when it was being done as you've told us every little detail anyway Seriously though, i'd put money on it being either overtorqued or lack of sealant. Either a poor seal or stretched head bolts, imo (and in this case - there are many potential causes for other ones I'm sure)

Has the car been sorted yet Kelly? Hope its on the road to recovery!

[Elaine]

Kelly who else is having trouble?? Might help if they gave there thoughts on what’s wrong with there cars....

At the moment it’s only yourself/bf that have voiced there having troubles and as a possible future buyer from speedvision I for one would really like to here what they have to say

Yeh ive told everything even the sentance above which came out his mouth. But like i said i wont take word of mouth.

The engine is coming apart this weekend, if it is the headbolts wont it show when we take it apart?

I can honestly say the other one with the failed HG was torqued correctly by a toyota mechanic and it was blowing after a week.

I'm sure they will reply when they see thread. Im not going to go out my way and force them as that kinda gives the wrong impression.

 

[Dave.]

Perhaps a few faulty ones can slip through the net? Not wanting to comment on the quality of the item though, as it seems to be hit or miss, on or off, if you know what i mean?

Hopefully this time round it'll be ok. As for the headbolts, I can't imagine the stretch being noticable, but I'd take no chances and get a new set, if it was me... Coming apart a third time wouldn't be an option in my book!

I guess do it right or do it twice would be the motto...

Just my opinion mind, its your choice in the end!

no it wont.

any way were going majourly of track here.

this thread isnt about ben/kelly's car, only one thing was mentioned about there car, so lets all leave it now.

if people want to row, do it via pm

 

[Kelly]

Dave -- got brand new headbolts sat here waiting using them again was never an option.

Sx - i understand what u mean, but everyone else on the first page was commenting away and turned it into this

back on track opinions.......

 

[Dave.]

Ah, good to hear, I just thought I'd give you my opinion on that, jsut incase

sx_turbo is spot on though, back on track!

This forum gets worse and worse! my god, the reason kellys k24 car's headgasket has gone is no way down to the headbolts being over torque'd, its because the headgasket is not up to the job, im sorry for being so blunt but my speedvision headgasket lasted me the whole of 1week before it started blowing past and I MYSELF TORQUE'D THE HEADBOLTS and i they were 150% perfect to the torque, i have not one bit of doubt about the torque! and also my headgasket blew at 1bar so theres no way the headbolts stretch either, the head and block were checked for complete flatness which they were so theres 1 thing left and thats the headgasket.... brand new speedvision headgasket which let me down.
