My Head Gasket went up the Motor has about 10k after the rebuild.
I was using a Lindsey racing wide fire head gasket. My question is that are all the HG the same Lindsey, Powerhous, Guru is one better then the other ?

Thax for the help.

 

I heard the guru headgasket was a great choice, but this isn't the first time the lindsey gasket went out.

 

In my first 951, I never had to replace the head gasket and I ran that car very hard. On my current 951 I have had a total of 3 blown head gaskets, in the last time a guru gasket was installed, the head gasket did not blow anymore, but I got a broken ring and damaged my block. Now I need a new engine.

Just tune your car properly there are guys on this board running 16-18psi on oem or wide fire gaskets and they have no problems, get the right air/fuel ratio and you will be ok.

Hasta la vista baby.

 

read all of this,,,then it's your decision.

I do have a new Guru headgasket for sale, $100 plus shipping.

 

Well thax for the help I am going to pull it out to day and see what prob is why it went up.

 

I think this is best thing I've heard over the last few months on the headgasket topic. If you're blowing headgaskets you need to figure out what the problem is, not put a stronger gasket in. A headgasket is a relatively cheap fuse when compared to heads, valves, pistons, rings, or even worse...........blocks. I've been running 16psi for several years now on and off the track without issue on the original headgasket. If you're not running excessive boost (19+) then a stock or wide fire gasket should be just fine.

I have a friends car sitting at my house with a 3" crack in the #2 cylinder wall because the guy he picked it up from didn't get his A/F ratio's in check and thought a wide fire gasket would solve his problems. BTW.....Anyone have a block they want to part with?

 

For sure the problems are never with the Headgasket. But when replacing the gasket, use a more modern type. If there is ever any problem, these MLS gaskets will help where the solid type will not. The old style gaskets are for those who do not wish to upgrade to a better system. That said, the MLS gasket will NEVER solve other problems.

Doesn't sound like the "fuse" worked in this case.

 

TonyG,

What fuse? He replaced the HG the last time with the guru metal gasket. Instead of that failing, he cracked the block.

The moral of his story was to use a standard or widefire gasket IMO.

 

FYI... the full metal 3 piece gaskets are not new technology. They are factory gaskets on several cars for the last few years now, aren't just for the "performance crowd".

These are the gaskets to use now.

The "safety valve" or "fuse" theory is just that... a theory. The fact is that it won't save you from anything other than letting you run with a slightly blown head gasket for some time, causing all sorts of other problems.


Get the proper head gasket. And there is a difference in the one for an engine with "O" ringed heads and/or blocks and one without.

Sorry Tony, I was thinking of part lart951's post and part Jeremy's
Here is Lart951's so you dont have to scroll up...

Unfortunately, the wide-fire gasket doesn't "cut it" for sustained loads over somewhere around 350RWHP - 370RWHP as even without detonation and perfect a/f ratios & ignition timing, the fire rings deform (elongate and just plain stretch out), which will for sure lead to cylinder leakage.

I've got a few on my work bench to prove it.

 

Yes the MLS gasket is not new, but the application for the 944 is new. These gaskets are used by most race engine builders today and have been for some time. It was PD who decided to do the 944 application after Guru saw them at PD used on one of PD's racing engines. That is what brought PD into the 944 engine world. Just goes to show how current (not)the established 944 Tuners were.

As for those who think these gaskets cause engine failures, keep thinking this way and you will be left way behind. The day of the wide fire ring is gone!
