JH 8v knocks when cold
<html><div style='background-color:'><DIV>
<P>An excellent method for isolating the bad rod/wristpin is to pull the plug wires off on at a time until the offending noise changes or stops. It's probably a good idea to pull the wires with the engine off and lightly set them back on the plugs before start-up.</P>

<DIV></DIV>Knock, wrist pins/piston slap. ticking, lifters/oil pump. i doubt that it is an oil pump. usually this exhibits itself when the engine is warm.

<DIV></DIV>>The knock is just the sound really, it doesn't shake the engine.
<DIV></DIV>>It's not very loud, but definately audible. Maybe my pump is going
<DIV></DIV>>bad? I thought I had my winter oil set-up pretty good; Mobil-1 full
<DIV></DIV>>synthetic 10w-30 and a NAPA Gold oil filter. If this indicates that
<DIV></DIV>>my wrist pins are going bad or something, I'm going to cry-

<DIV></DIV>>saying is that the clattering of valves on a cold engine is normal
<DIV></DIV>>until the oil comes up to the top (your engine is not hydraulic
<DIV></DIV>>valves) yes, but are we talking about KNOCK that shakes the engine,
<DIV></DIV>>then no.. which is it?

<DIV></DIV>>OK so you're telling me my cold morning knock is normal I hope? I'm
<DIV></DIV>>just very anal since I built this engine myself, and in my case that
<DIV></DIV>>does not make me rest easy:)

<DIV></DIV>>Hey all,
<DIV></DIV>>now that temps are dipping well below 20F here, I have noticed in
<DIV></DIV>>the
<DIV></DIV>>morning when I start up my '84(stock 1.8 JH with 8k on rebuild), it
<DIV></DIV>>sounds
<DIV></DIV>>as though it is knocking. Not like an insane erratic knock, but a
<DIV></DIV>>constant
<DIV></DIV>>knock-knock-knock-knock, well you get the idea. What's going on? The
<DIV></DIV>>sound
<DIV></DIV>>goes away once warm. I'm running Mobil-1 synthetic 10w-30 if that
<DIV></DIV>>has
<DIV></DIV>>anything to do with anything. Thanks to any who can provide even the
<DIV></DIV>>slightest info/help on this-
<DIV></DIV>>Rob
