Click on this link now, It's been updated, He's got stainless steel and aluminum head gaskets now, How do I know if I should use a regular Dvorak no blow, or a stainless steel Dvorak no blow or an Aluminum Dvorak no blow?
I've given up on ever getting around to replacing the blown headgasket on my '88 Forsa turbo so I'm paying another Teamswifter to do it for me. So I need to get this Dvorak no blow headgasket now.
Jamal Spelling: Is this Dvorak no blow in this link the one you used in your '87 Sprint Turbo? It says 89 to 00 but if it fits your '87 Sprint turbo then it will fit my '88 Forsa turbo.
I'd call Dvorak myself later today but I can't find my cellphone and the battery's dead so I can't phone it to find out where it is.
Addendum, I just reread the article and I see Jamal Spelling used a Felpro, not a Dvorak no blow. So I'll have to try and find my phone and call Dvorak. But if anyone could tell me whether or not that 89 to 00 Dvorak no blow in the link fits my '88 Suzuki Forsa I would appreciate it. Thanks.
And he makes aluminum head gaskets in any thickness you want. So I wonder if you could TIG one to a head that's been planed too many times and restore it?

I've been saying this for a long time

Nonetheless, if you use any of the aforementioned gaskets and are blowing them, you have another problem. My gasket of choice was the cheapest (topline) $20 gasket I could find, and only ever blew one when I did something wrong. The G10 is not a motor with cylinder head sealing problems.


Don't waste your money on that Dvorak gasket. If you want to spend some money, get a Felpro.

Thanks, I'll get the Felpro then. Much easier and quicker to get too, I can just go down the street and get it for a relatively good price.

The head gasket gave indications of failing after about 8 months,
the motor had developed a slightly rough idle at low rpms.
Cold startups were also a bit off, as it took a few moments for
the high idle to 'kick in' and stabilize.
Initially I attributed it to possibly the headwork and larger valves
that were installed, but eventually I noticed a bit of oil in the
coolant reservoir which was a tell tale sign of a failed headgasket.

She had to wait months in que to be fixed, thank goodness for holiday
weekends.

Perhaps I should have retorqued it somewhere along the way?
Adding a Manual Boost controller helped speed up the failure
as boost was dialed in to just under 10 PSI.

I'm installing Mark's No-Blow gasket this time and will retorque after a few
100 miles and see how long this lasts.

Unfortunately, right after I retorqued the head back on after replacing the
gasket, I noticed something missing.

I found it lodged in an oil drain passage, and being I had replaced them
with stainless steel screws, a magnet was no help. It was a bit tricky
to fish it out. I checked all the other screws, which were loose and tightened
them to specs.

Interesting note, upon reassembly, I discovered the larger valves now makes
this an interference motor. I did not catch this the first time around.

Off and running. Got to do the axles next, that last jaunt earlier this year with
the guys in Ventura Canyon compromised the outer CV boots and made
a nasty mess in the wheelwells. Hope the weekend lasts..

Failed the smog test, had to get a new cat.

Interesting new design, non-directional, looks more efficient with increased
internal surface area.

Will post before and after results whe I get the retest.

Installed one of those a long time ago. Good flow and reduced the important stuff just enough to pass my e-test. I believe they're used as a pre-cat for large engines that need one.
