Head gasket for 82,5 stroker....

[th.b.w.]

Hi,

where to buy a headgasket for a stroker 82,5-83,0 bore.

PKM seems expensive -300,-€...

Is there an other source ?

Ebay or every other autoparts seller?? It is the same as for the overbore S2/RS2 and i think either Victor Reinz or Elring makes them.

Also 034 motorsport do one but it's 300 dollars.

I looked for an oem solution a while ago with no success

I'm running 82.5 with standard stroke, so need an 83 or 83.5mm gasket.

i have a torque plate made up to over bore the original gasket but these are not cheap after you have put some time in on a mill.

I used a VW Transporter 2.5TDi MML Elring gasket for my old re2500 10v engine, and that had a 83.0mm bore. Im fairly sure it will fit the 20v engine also. About £30 from GSF.

I did exactly this with my two last HG's James, i made a jig and machined out the gasket to 83mm.

The problem with this is the inner (0.1mm) steel layer is folded back on itself to create a fire ring and after machining this ring drops out (well it did on mine) which renders the gasket useless and the gasket wont seal properly.

Thats interesting,

Did you do a compression test to confirm this?

What did you do in the end? standard gasket?

I had a look for this gasket when you mentioned it in a previous thread but had no luck in finding it

My local machine shop had a look too but all the 2.5tdi's they could find had 81x95.5mm bore stroke so the gaskets are 82mm

Yeah i searched Ekta but could find nothing!

So how did they fail Baz?

No, i did about 7 runs up the drag strip with the 1st gasket and about 5 runs with the 2nd gasket.

The 2nd gasket i was using nitrous and it just cant hold the pressure and was blowing water out the expansion bottle every WOT. Still managed a 10.7 :mischeif:

Also det was absent so was not to blame.

I'm still looking for a solution and i may have to strip the engine and machine the pistons to clear a standard gasket

I resent paying £200-300 pounds for a uprated gasket from a tuning company.

Thats classic

I spoke to a gasket company in Brum he could help but it was £250-£300 and copper made in any size. But that was a one off. Maybe he could sort a better price out for a few.

He suggested milling the OEM gasket thats why i went down that route, i mean everything seems to be okay at the moment but like you said your cutting all the multi layers and if there folded and ment to be that way... Well...

[gnutz2]

Everything is ok until you start to give the engine some beans.

I may just take the pistons out and releive them slightly and use a standard gasket.

[repo]

Why am I quite positive the Reinz gasket doesn't have a fold of any kind? Ajusa or Goetz might have, but I think Reinz doesn't..

[Billman]

It's ok if the gasket protrudes in the combustion chamber even if the piston clears it?
