Isuzu Engine Specs?

[jking]

I have the Isuzu 6BD1A engine in my AS MH. The engine and chassis date to June 1983. After nearly 200k miles I need to reset the valve tappet clearances. Does anybody know what those clearances should be?
Thanks,
Jamie

.016" both intake and exhaust cold.

Re- torque the rocker shaft nuts before adjusting the valve clearance. 22.4 ft-lb. I'm suprised you have not pulled the head and inspected the valves; it's overdue.

Thank you both for valuable information. I'll proceed with this job when the weather gets a little less frigid.

I can't remember, but it seems the radio console and the doghouse has to come out to get at those front valves. Lube the water pump at the same time.
