well i'm surprised even with the copper head gasket... did he o-ring the block & the head though???

SMOKEYDUB · « **Reply #32 on:** April 28, 2007, 05:09:13 pm »

yes he did

i wonder how blake was keeping his jetta together at 40psi on a 1.6td. with a 1.6 head. i believe his was fine until he put the 12mm pump on it then he said the headgasket blew out, like literally missing from the head

thsi was more of a post for the 1/4 mile thread lol, i got confused... he ran a 15 something with the 9mm pump.

not sure how he squeezed so much pressure out of that turbo. Pressure is a result of restriction. maybe there was something screwy with his.

:shock: hey wtf did my hg go??? :lol:

what type of head studs were you guys using? think maybe the type has anything to do with it???

and may i also ask what coolant temps you were seeing? maybe running a cooler thermostat may help keep the head temps in check

i just find it hard to believe that the 1.6 will only hold 30 psi... especially with copper HG, o-ringing, and head studs

RabbitJockey · « **Reply #37 on:** April 29, 2007, 09:16:31 am »

i think that 30 psi with the amount of flow his motor had, and all the fuel... it's the cylinder pressures thats killing them haha. cause you gotta remember that what ever hp a diesel makes it has around twice the cylinder pressure of a gasser with the same power

i tried some hardened capsrews and the wouldnt hold it so i went to arp and they felt alot better and it would hold a headgasket for about a week or so.

lol only for a week? have you tried raceware head studs? 190'000 psi tensile strength or something like that...

is it actually the gasket material blowing out??? that would be some pretty serious stuff if it was... time for titanium head gaskets :roll:

i am only using the 1.9 mls headgasket.and you cant really physically see anything wrong with it. the head just temporarily lifts of the gasket pressurizing *** then comes back down. there is alot of flexing going on in these heads.

RabbitJockey · « **Reply #41 on:** April 29, 2007, 05:17:47 pm »

haha we need aftermarket iron heads perhaps... then heat would be less of an issue.

a week? so long? :lol: I've got stock 1.9td goetze hg, stock bolts, egt skyhigh

and it holds longer than week

my setup: 28psi, k24, 10mm pump, really poor ic

The metal HG is not the problem here and probably not even the stock head bolts.Its the head that is the problem as the EGT's go through the roof combined with lots of cylinder pressure the head seems to flex.The IDI with higher cylinder pressures and prechambers taking away from the heads strength and adding higher temps to the head with high EGT's through the prechamber area is a recipe for desaster and lots of cracks.Tdi's don't have to fight most of these problems therefore can make more power with less issues.

Maybe some sort of head bolt girdle would help. Just fitting one under the valve cover? :roll:

Also would using the thinnest gasket help eliminate it?
