>>>*One thing to check, there are some grommets in the firewall that help to shield noise from the cab.

I drove one of those and thought it was noisy as all getout, but when I got out of it it was..well, as normal as they get?

So I got to snooping and found nothing wrong, even put a remote oil pressure guage on it. That read 12#, oceans, the stock gauge was scarey.

Finally I read a post online about the firewall, I think on the old T4X4pickup.com board, checked and yep. Grommet gone.

Got one, stuck it in, they are split and slotted so that was easy.

Noise all gone....*EB
