97 RS 3800 series II got a LOUD knock

well, i bought this car knowing it had a possible rod knocking but the more me and my dad drive it we think that it is not a rod because a rod is more of a thud noise and this noise comes, and goes and is more of a ping and seems to come from on top of the engine. i would really appreciate any ideas as i would love to get this car fixed before summer comes around.
Thanks for your ideas!

Might have a sticky or dirty lifter. Myself to clean, I run Mobil oil and change three times every 1000 miles w/filter.
You also might add a mech oil pressure gauge just to monitor it to make sure it's not low, say below 15 PSI.

Good listening to the both of you.

Re: 97 RS 3800 series II got a LOUD knock

well here is some more information, when i started it after i got out of work last night i put it in gear, and when the rpm droped to 1k the knocking all most went away all together. and would stop for a few seconds and twice while driving the oil pressure droped off to 0 psi and then came back up in seconds...
Any ideas? i don't think the lifters would do that but im not a mechanic so please help
