Just letting the engine idle with or without the Marvel will allow the
lifter to eventually pump up. The reality here is that you have a bad
lifter. When you have the noise, remove the valve covers. Turn the
engine to TDC for each cylinder and then check the rockers to find the
loose lifter. When found, the lifter can be replaced with along with a
2- piece push rod tube.

Subject: Mixing Marvel and Redline?

Hiya all,

Every now and then, if I let my van sit for a while, she fires up and
clacks
something awful. I've fixed this before by dumping half the oil and
topping
off with Marvel and running until the noise subsided. Then I drained all
the
oil and refilled, replacing the filter at the same time.

My question is this. Is it a bad idea to mix Marvel and Redline? Say
half a
quart. I run Redline 10w30 in the winter and 20x50 in the summer. I've
just
never mixed synthetic oil with Marvel before and I'm wary.

Thanks,
