Check compression on that cylinder? It will be down if the rod is bent compared to the others. You could have easily bent a rod with a hydro-locked cylinder.

Is it possible to bend one of these stout rods at idle or while cranking the car over?

Probably isnt it but my flywheel just ate my crank sensor, my string of bad luck will not stop...the car would not start, when I got it started I could hear a high speed tapping, it was the sensor teeth hitting the sensor, kind of sounded like a valve, at first I thought valve train... if everything else checked out might be worth pulling it out and looking, dropping my trans out again twice this month haha, getting terribly good at it.

We may be related, I just don't remember having relatives in PA :confused:

That's not possible unless the flywheel is physically loose from the engine and then I doubt it could happen. Sounds like something is in there and got spun around hitting the sensor. Maybe a pressure plate bolt broke or came out?

I looked though the check plate you can see the teeth have wear marks on them and there is a slight gap maybe an 1/8 inch between the ring and the flywheel on one side. Ill know tomorrow for sure.

I'm guessing the trans was not lined up correctly with the dowels, Dowels are missing or the trans was loose.

When you pull the trans take a good look at where the block dowels go into the trans and see if they are damaged or the trans is gouged out around where they are supposed to sit.

they are there I can tell you that. The sensor however is bolted to the engine, not the trans housing, and the flywheel is bolted to the engine, so even it is was hypothetically, I cannot see it moving the flywheel in any way shape or form, but I will let you know what I find, Shane looked at it and suspects the tooth ring crack and shifted, this one is way thinner that the one on the steel flywheel...

You are correct on that, I was evidently thinking DE style on the sensor placement. Curios to know now as well.

So my problems were associated to my injectors. It really sucks spending $700 on high performance aftermarket injectors and they go to hell in 3 years. Chances are it is just one but still really delayed my build and has cost me a lot of time and money.

Put my new set of ID1000's in and it purrs like a kitten now. About time!

I guess not like a kitten since my scavenge pump still sounds like a tractor and drowns out any purring.

Sasha,

How do I get this to stop? Sounds like some of you guys haven't figured it out yet either. I have let my car idle for 15 minutes and revved it up trying to flood the pump so it turns to the "hum" it is supposed to.

Maybe after driving it for a while it will fully flood?

Its just the way that that pump is. However when the car is idling you really cant hear it on my car. When the engine is off however you can hear it over everything else on the car.

Can you hear it over your car idling if your standing by your drivers door? I know I would have to focus on it to really hear it at an idle.

I can hear mine over idle inside the car

:iagree:

It's kind of nice cuz I always know its working. I do have to pull the fuse on the relay if I want to work on the car with ignition on but not having the car started.

I pull the disconnect plug. Depending on how you routed/installed everything it may be easier.
