Blown head gasket questions

[LANDAU LIMITED]

I've had a fuel cell since 88. It still has the original foam in it. I never heard that before?

 

[SCOOBY DOO]

The two cars that had it happen ran race gas. Brand of fuel cell unknown,

Not always .

Liquid, in suspension, subjected to 2G's of force, plus 30psi of air pressure would tend to "blow" the mixture to the rear of the intake.
Maybe why a port injection,{or some other nefarious method}, alky system may help keep things under the head?

The g force effects suspended fuel vapor but not liquid in a tank?

nice!in like how you jumped on it,i never like to let stuff sit myself

Looking at the spark plug for that cylinder, I thought it might have a problem by looking at the spark plug that came out of that hole.

 

[michael evans]

Okay who’s logging alky pressure?

Did before changing to E-85

With that tune up your lucky you have a plug but if you want you can send me the pic

 

[Mr.Spool]

Facts? Why is it always 1 and 2 cylinder that blow?

what fact are you saying that are facts?here is real fact there are a few of us that have and know how to move alot of alky through the up pipe without the issues or walls you speak of.how many gph do you flow that you are seeing issues?let me put it this way if your below 50gph and losing your number 1 i will tell you its not the fuels fault

You blew 1-2 on e85?

 

[Mr.Spool]

" i extended the line coming off the tank several feet to hold more alky= no issues with pressure>
An old Smokey Yunick trick with his NASCAR rides.!

guess im in good company

You blew 1-2 on e85?

No, it was still 93 and Alky when it blew then I changed over.

So now I have two sensors for fuel pressure. One before the injectors and one after.

You were logging alky pressure when headgaskets blew and logs show pressure steady with no drop?

read it on some racing forum site... ...unsure on authenticity...of that which was said...but you have real deal exp...

the xfi had the wrong target afr with the wrong timing.if he wants to post his high recall on the xfi at this point he can i wish he would at this point since many people have bullshit theories but the log doesnt lie

an rjc plate and High Pressure will fill the intake evenly

I did not see a log. So, without seeing a log, I see the 2 front cylinders blown multiple times. He did not say random cylinders. 1 and 2 every time. Your theory would suggest that the afr target and timing was specific to 1 and 2 cylinder only. I am not arguing that the targets were off but it does not appear to be a global issue.

It's been proven that the front cylinders take the hit when alky does not get to them. The reasons for not getting to them are debatable but the end result is very clear.

The coolant overflow tank sucks for alky. That is a fact like no other. It's not "Rocket Surgery" as BB would say. Itt is backwards sir.

Can the backwards alky tank work? Hell to the yeah as long as its kept full and under boiling point.

im not theorizing,consider them collateral damage

mead not planing on a full run as I was rushed by the track personnel to run and did not get set up.
Won’t do that again.

im sure if you saw the log you would see it let i see itICEBERG RIGHT AHEAD

trust me i could blow your front 2 cylinders up if i dont like you or i can can even them out if your on my good side.morals are in between and so are mistakes

 

[michael evans]

It could be worse but is no longer funny. I have paid my dues in that I can now lay out the tools needed to take the engine apart.
For some reason the XFI really made a change. When I get it back together, I will take it to someone that knows this system better. I thought I could fiqure it out myself as four heads gaskets later says otherwise.

Almost makes me want to move on to something else, but I don't want to go slower.
