Shaun i beleive you had some copper mainfold gaskets made up? Im fed up with blowing the standard gaskets every other day:furious

hi adz its stella, i know shaun had them done at ferriday engineering. 01785 / 621710.

Any ideas on cost and wether he could get me some made up and posted:)

when i last rang ferriday shauns gasket pattern was still on file so i would imagine you wouldnt have to send a template if thats still the case

the pair was no more than 15 pounds.give him a bell he'll get you some made and posted.:)

cool do you have some contact details;)

hay adz, lay off that right hand,:D your going blind, i've posted the number;) :D

:o hahah oh yeh

It seems weird that you are getting the gaskets blowing. I've not had any problems with mine.

Have you tried a different manifold? There must be an unmatched surface on either the head or the manifold, it would be better to solve this then getting copper gaskets made up. You'll be pissed if it don't even solve the problem if the mismatch is too bad.

I have a few manifolds so will take a look but im sure i picked the best one i had when i built it all:confused: think the main problem lays within my studs coming loose, im gunna have to helicoil 2 more studs now. I only did 3 when i was building it up as the other 3 were solid.But im gunna use copper gaskets too as there gunna be better than the standard ones.

mine used to melt the top left corner when was being mapped on the RR, but since i've used the copper ones they are fine.

The bottom stud nearest the bulkhead on the manifold became weak as the gasket blew there twice and now its fallen out :ghey dont know why this is such a common problem with these heads. Even after i helicoiled 3 of them and used loctite on the threads i still have to nip them up every few days:(

Just been on the phone to ferriday and im being sent some new gaskets that the guys been testing for a while now. Apparently there 6 mm thick and have been tested to high temps that will stop the heat going back into the cylinder head, so il try them out as there free of charge nad see what happens. If there crap il use the copper ones but i dont mind my manifold being the lab rat for some new and maybe improved gaskets:)

sound job;)

Shaun did the guy mention these new gaskets to you? Or did you just decline the offer of trial?

6mm seems very thick. Hopefully the nuts can go fully onto the studs (sounds very gay that)

i don't think he was doing them when i had my copper ones made, hope they work well matey, if only there where some head bolts out there from ARP, i'd try one of there copper head gaskets and wind the boost up to about 32psi.

I thought this straight away but im sure theres about 5-6mm thread left after the nuts have gone on using the standard gasket so trial and error is all i can do:)

should be very very easy to get ARP's for an ET it's only a standard m10 thread, not like the M11 on the DET

YEP this is true. Arp will have some on the shelf if you specify the thread rather than the car type.

The gaskets sound pretty interesting Adz. Post a few pics and a review up if you can mate. As you say. there thick to reduce heat transfer back to the head from the manifold which eventually weakens the ali. :cool:. Who cares if there thick if they are uprated. I used to blow mine on my et. I guess were just to hardcore for Nissan, :p

Yeah wil lpost pics and feedback when they arrived and are fitted;)

Ok the gaskets have arrived....

They look like there made from cross between mdf and dog biscuits lol, il let you know in a couple of hours how they perform as thats what matters;)

sure is a nice day to be working on the car adz

looks like paxolin:D does anyone know what they are actauly made of tho:confused:

Ok there on an the car is as quiet as a mouse, well besides the the loud exhaust system:D

They fitted great but the only thing i will say is that when doing the nuts up, i think you could continuously tighten them to the point of maybe splitting the gaskets,i certainly dont want to have to be tightening the nuts up every other day:mad: Il see how they go but also because they feel quite britle although there 6mm thick maybe over time they will become too britle with the heat and could cause problems.

But i was told that they can withstand very high temperatures and will keep the heat from travelling back into the head so only time will tell.

Gaskets
 

Adz, i have a set of the new gaskets from Mike at ferriday and they look fab but havn't put them on yet.
The guy is very clever and is up for any advise anybody may need.
I use slightly thinner copper gaskets than shaun at the moment but they work really well.

If you need any allen headed bolts 10 by 1.25 thread ( about 60 mm long) for the manifold feel free to have six f.o.c from me mate.:) :)

Nice one kenny:D Although i have 6 frsh new helicoils in and studs etc, i have a feeling there still gunna come loose:mad: Did you have the same trouble and therefore opted for the allen bolts? How do they hold up compared to the std studs and nuts?

Allan bolts
 

Hello mate, the only reason i used them was cos i made the manifold so i could top mount the t3 but they seem fine. i use a very high grade thread lock fluid and they seem fine. Put a steady bracket on the manifold helps but i reckon you may struggle to do this on a standard one. i have always said its as much the weight and movement on the standard manifold that causes the gaskets to blow but mike at ferridays has a good point when he says the standard gaskets just can't take the heat from pure thrashing:D :D

Like i say mate your welcome to have six.f.o.c. just let me know. i had to cut mine to length but that not a problem.Four of mine are helli-coiled.

Sounds good to me mate , il pm you my adress later and its much appreciated;)

Your spot on about the weight issue playing a big part in the studs stripping the threads, seeing as i wont be opting for a top mount im gunna look into a brace of some sort to help support the turbo and reduce weight pulling on the maifold.

I expect they may harden once they have been up to running temperature a few times

yes i think a lots to do with the extra weight on the studs, with my turbo looking something like the dinosaurs ribs on fred flintstones car, i'am sure if i had not made a big brace that it would have stripped by now,;)

I expect they will mate although that could be a good thing or a bad thing as they may just crumble.

hey adz, you've ad me staffy barkin at those gaskets:D mines sound on the studs mate, i've got an 8mm thick stainless bracket that goes to the block.

OK bottom half of the gasket nearest the bulkhead blew out and caused a massive tractor like bang at 130mph!!!!

I might add that the doctor was driving the car at the time lol

We went to the seafront at brighton and all was going well,i offered a drive of my car to the dr_silvia, he was steadily cruising on the carriageway on the way home at 80mph when i told him to boot it.

So at 130 we heard a mettalic like tin noise then bang:eek: I got greedy earlier in the day and turned the boost up some more:trout think i over cooked it by a turn as we are pretty sure this was det.

Pulled into a layby and the turbo and manifold was pretty much glowing white:eek: and spitting flames out the bottom corner of the blown gasket.

I dont know 100% if the det etc caused the gasket to blow out or not but no doubt the turbo and manifold will be coming off again tomorow aswell as inspecting the plugs etc

Just what the doctor ordered:rolleyes: :ghey

greed:D

:o i wish i had known you hadnt taken it that far before, i thought it was safe:( love the way you preach to me about not using a guage to set boost then tweak your own the next day lol:p :rolleyes: don't think we've done any major damage though so we should be happy for that:) can ye keep hold of the buggered gaskets tho cos i wanna have a butchers at em

You 2 are terrable. Fit bloody boost guages that actually tell you an accurate reading before winding your boost up 'willy nilly' !!!!. :p ;). Going 130mph on your private road with unknown boost and standard fuel pump, larger turbo will most definatly of caused DET.Sorry for nagging or whatever,i dont wish to row. Im just surprised you did that after seeing the state of my mk2s piston from a high speed run at only 14psi. Especially on your freshly fitted new engine.

i've never had any probs, at 26 psi and a quick burst at 30 psi. my copper gaskets are still in one piece, the exhaust manifold was glowing cherry red, but the gaskets are still in one piece.

The reason i turned it up was because it didnt feel like it was running a bar anymore, as ive had boost controllers that have lost boost over time,why would i try and cook my engine lol

Jon didnt you run 20+psi on your old 8v in the black one with a t25 and standard fueling?

Dont be petty

LOL petty? Im asking a question?
