running too lean
So i just finished watching a few HHO videos on youtube. I watched a series of videos from one user. He had hho and was getting very good results for quite some time. He had a hho generator pushing out quite a bit of hho, enough for his truck. he had an efie set at around 370 mv. His engine completely stopped working. Bearings fried or something... Anyways he said he thinks he was running his engine too lean, but did not feel it running lean when he was driving.

Anyways... I am about to install a dry cell in my car and purchase an efie and put that in.

I am trying to avoid destroying my engine.
Why did he not know his engine was running too lean?
So how do i avoid what happened to him?

RE: running too lean
I suspect he was in denial or didn't know what to look for.

You've gone too lean when one of the following occurs:
CEL
no gain in mileage
loss of power or other driveability issue

RE: running too lean
The best bet would be to run an EGT gauge. Anything over 150-180 degrees F. over normal running would be too hot for the engine.
You water temps won't rise while the engine is burning up until it's too late.

RE: running too lean
150-180 degrees? That's coolant temperature, and it's too low at that. Most engines perform better and get better fuel economy if they are operated in the 190-210 degree range.

As far as EGT's are concerned, normal EGT (Exhaust Gas Temperature) is about 1200 degrees F. Anything over 1600 degrees is causing damage.

Running lean can raise EGT readings, but, if you go TOO lean, EGT's will start to drop. Same goes for too rich.

As far as "can't feel it running lean"...you'd have to be completely numb and oblivious to the world not to notice a lean condition.

Easy signs are surging, poor throttle response, loss of power, and fuel economy going down instead of up.

RE: running too lean
Saltmine: read it again. I said "Anything over 150-180 degrees F. over normal running." This was the suggested limit by an engine research group.

Ok, then we dropped from two to one engine blown, possibly dt too lean.

RE: running too lean
Guys you need to check the plugs. The plugs will tell you everything you need to know in regards to being to rich or to lean.
