Sudden loss of compression! only 20miles of hho

[deadcorolla]

I recently had my 4 cell working in my 89 Toyota Corolla and it died last night. I had it towed and check the compression and got 0 0 0 70 and a wet test read 0 0 0 105. This Sucks! The engine has about 30,000 miles on it
The HHO cells were only on there for about 20 miles.

I don't know what happened yet. Maybe water got in the engine? Maybe it skipped the timing belt? I've heard no ill effects of HHO and so much goodness about it. One thing I didn't do was tune the carb for the hho. I just wanted to drive around and feel any difference. I don't think the hho would have washed the oil of the cylinder and caused the rings to be destroyed.
There was no indication of malfunction. It just died on the spot.
Any Advice?

post some pics of your spark plugs..

it's unlikely that HHO caused this.

what all mods do you have on your toyota besides the hho cell??

we need a description of your setup in order to make some educated guesses.

if you lost compression in three of the four cylinders it seems you blew the head gasket

that was my initial thought as well..

how's your antifreeze look?? or your oil ??

these could help tell if it's head gasket related as well...

Did it make any noise ? had a guy drop a washer in his carb took out 4 cylnders of a v8

As said before, sounds like a head gasket. A good indicator would be to check your oil. If the dipstick looks like it has vanilla milshake on it instead of oil, it is most likely a gasket. Or worse, a cracked head or block.

OR... Did your engne eat some mounting hardware for your HHO inlet hose?

Good luck $$$$$$$

[deadcorolla]

yeah all of this sounds good.

The oil looks OK, the antifreeze looks good, and the mounting hardware is in place. I have a 32/36 Weber Carb and all the emission removed, besides that its stock. I hope its the head gasket and not the piston rings!
This engine is pretty fresh and there have been no other problems lately. There was no noise when it happened, it just died. The silent but deadly kind

I would point to the hho because everything was fine until I installed the cells.
Is this a coincidence?

The plugs look fine, and look like normal condition. I will post some pic's soon

The important thing to remember about hho is that not only does it increase the potential power of the combustion explosion it also increases the flame speed, that is the time from ignition spark to completion of the burn, petrol vapour is slow burning that is why ignition timing is set several degrees before top dead centre so that maximum benefit from the burn is received at or just after top dead centre, the addition of hho reduces the burn time considerably which means that max power is delivered Before top dead centre which in turn means the combustion explosion is trying to force the piston back down the way it came this means that combustion pressures are far exceeding design tolerances and set to cause damage to the engine, the weak point is the head gasket and usually the first to go. I am currently working on an old (pre electronics) 2000cc volvo engine to determine the optimum timing adjustment. A similar problem limits the amount of hho you should introduce to a diesel engine, i had a toyota diesel the showed a 30% increase in mpg until i tried putting more hho through and subsequently blew the head gasket (twice) i have also blown the head gasket on a petrol toyota and was then advised that toyotas are inherently weak when it comes to head gaskets.
Adjusting the timing (retarding) will also increase the effectiveness of hho again due to the flame speed, hope this helps.

You do realize you just responded to a thread that has been dead for close to three years now, right?

this is so true, this is why i prefer VVT engines or engines with their version of VVT but when tuning with a AFC i have never faced this problem.
