Blown Engine, 8.1l

Dave,
Were you by chance in the east Monday around Hagerstown MD on I-81. Reason I ask, was a RV like yours going north with the same paint job & colors, nice looking rig all shined up & I thought it might have been you.

Sad to say that would not look like my rig, as mine is an embarrassing mess. It has sat under an Oak tree that has graced it with excessive crud. I'm hoping I can give it a quick bath before I get on the road.

Since the 8.1L GM engine has hydraulic ROLLER lifters I doubt if you heard any tappet noise at all. What you MAY have had was a more common exhaust manifold gasket leak.
I know several 8.1L engines that are well over 100K miles, mine included in my coach.

I would bet you heard the fuel injectors. They are very noisy. I had to listen to my dad's for some time to determine the noise was the injectors. Yes it sounds a lot like lifters, but its the injectors. The way to verify is to listen when you first hit the key, before you crank the engine. You will hear the same noise.
