Did the rpm drop less on any cylinder?

No......same sound with each one removed

[Steve Wood]

And the rpm drop was similar on each cylinder?

Yes

Chris Garrett has a new screen name? Sorry Steve...couldn't resist.

So crank it up, turn out the lights, and look around under the hood to see if you see any sparks jumping to ground

Just checked...blac k as night, no sparks.

Damn....get a stethoscope and try to narrow an area down as was suggested.  It might be lifter, I guess.

Check the front cover to see if the noise is coming out of there as on the tensioner as mentioned

I will get one tomorrow and check around......wo uldnt a lifter, pushrod, bad cam lobe still be easy to hear in park. Seems you need to have a load on motor to get a tick? I dont understand it

[Steve Wood]

well, again, maybe....I thought maybe it was a piston pin, but that usually diminishes when you disconnect the injector on that cylinder.  Assuming the oil pressure is good, ticking lifters often disappear when the rpm comes up.  If the lobe is bad, or the pushrod bent, I would have expected less rpm drop on the cylinder affected.  #3 exhaust is usually the lobe that goes bad, but not always.

what is the oil pressure?

[Shimy87]

Warm its 25ish at idle. 50 when crusing.

[Steve Wood]

You have not been manually shifting the car when you were running it, have you?

[Shimy87]

Nope....and racing I put it in drive, not overdrive

[larrym]

is the sound louder in the car than out? have you inspected the flex plate?
