Lifter Noise

Brew52 · November 20, 2003

I have a lifter that clicks at start up and when its warm. It's quiet when the RPMs are up. Is it just sticking and can I do an engine flush to free it or do I have to replace it. Any ideas?

I should of posted this in the engine section.

Oh my friend...if you even knew...

I don't have time right now to post a long explanation, but look around!

I did a search and have the cold start knock and it's not that. It definitely sounds like a lifter and not the injector tick.

How many miles on it? Did it always do it? Try a good synthetic engine oil and a good filter with an anti-drainback valve. Can't hurt.

I found out with mine that the wrong filter (Poor quality, no drainback valve) makes a HUGE difference.

Can you help me understand what an anti-drainback valve is? Where can you buy them?

JayMan,

It has just over 70,000. My oil change before last ,I ran synthetic and no differance so went bact to regular oil. My oil pressure is good and only happens when idling. It doesn't smoke, burn or leak oil.

Seadoons:

Anti-drainback: a plastic or silicone flapper inside the oil filter that prevents the oil in the main gallery from all draining back through the oil pump into the oil pan. I've found that the K&N filters have a very good anti-drainback feature.

Brew52:

If the truck has that many miles on it, good oil pressure (At least 30-40 at idle), doesn't use more than 1 qt per 4,000 miles or so, maybe you don't have to worry about it? My 1984 Ford F-150 with 302 always made noise and it's still running with +300,000 miles on it.

Also, any good quality oil filter has an anti-drainback on it. The dealer AC Delco PF-59 appears to have one, I know the Mobil 1 Synthetic filter does. K&N brags about their high quality anti-drainback, and I've found their filters to be very high quality, though $$$.
