Please watch my video & please help me with suddenly noisey v8 engine

[bimerguycw]

And are you saying the oil pump bolts loosen-up regularly and cause low power and of course the cranking. The oil is and has been Mobil full synth 0-40W after the initial 20-50W for engine break-in.

Anyway to chck the DME before a replacement/repair? Do you suggest any place to exchange/repair the DME?

Thanks

gaskets are only 1 yr old? Is there a gasket sealant to be used to really seal-off the valve cover to head? It seems to be a re-occurring problem with these cars or is it all in the quality of the valve cover installation.
I have noticed oil in the PCV/Intake flat area and think it's from top timing cover gasket.

Any comments on these items? Maybe I should do a complete top gasket re-install(timing covers, valve covers and PCV plate and assoc. gasket around the PCV plate) with the proper gasket sealer?

do the top gasket reinstall, and also do the intake manifold and throttle to intake gaskets.

[bimerguycw]

Since the top end(PCV plate and up) will be dis-assembled, what else should I include...injectors gaskets or what.

Since the seals/gaskets relatively inexpensive and this is alot of labor to do why not include all gaskets, etc. under that area but what?

Thanks

Have you thought about doing a compression or leak-down test to rule out mechanical problems like a bad lifter or valve ?
The audio on the video is not the greatest, sounds like a valve train problem and a major exhuast leak to me.
What ever it is, it sounds like it could be a serious problem.
I hopes it's something easy to fix. Good luck on it !!

The noise sounded like a blown exhuast manifold gasket, but as I read more you mentioned oil...so I threw that out the window.

It sounds like everytime the piston is up top it is really noisy...hmmm

I dont know the v8s too well. Dual cam?? with vanos??

[BillionPa]

dual cam per cylinder bank, no vanos.

When I bought the car a year ago I did a compression test and all 8 cyl were within spec and within 3-4 psi of each other. This was when the engine was recently rebuilt by the prev. owner.

After having better sound hooked up today my oppinion is: SHUT IT OFF!

NO OIL PRESSURE

It can also be a broken rocker arm and the lifter flew out giving NO OIL PRESSURE (I dont know if this is even possible). Either way it's not a good thing.

Where is the oil leaking from?

Man thats a sick heart pounding sound... FIRST THING I would start by taping an oil pressure guage on it to see where that is at and then go from there. There is too much noise going on to really guess accuratley. The engine sounds real bad man.

my E30 would sound like that when it needed a valve adjustment lol. i sure dont miss that.
