piston slap?

[Vtechno]

are the f22's known for piston slap? i know the neons are and motors with aftermarket pistons. when i start my car it sounds like it knocks a bit, but then goes away. i had a prelude and i kept spinning rod bearing. im super paranoid about knocking motors, lol. that was a long time ago when i didnt know anything.

so what exactly does piston slap mean my man?

[riceraccord]

Piston slap is caused by worn bearings. Its bad

piston slap is caused because there is too much clearance(or just a rather large, not too much) between the pistons wall and the cylinder wall.

The noise becomes less apparent as the engine heats up because the piston starts to expand, decreasing that clearance.

Stock f22's don't have piston slap.

They have loud ass rockers tho.

usually only happens to motors which are overbored too much to run a certain sized piston.

whoa, wtf. Is this THE 98vtec? lol. welcome to the forum.

well if you are referring to 98vtec from honda-tech and preludepower...yes.

[m-tec93accord]

oh shit, i remember this guy, yea, welcome once again

piston slap can also come from a cracked and messed up skirt too

actually stock F22's can and do have piston slap. as a matter of fact there is a bulletin on it @ work, stating that it is common on older 4 cyl engines to have it on cold morning starts where piston-to-cyl clearance is greatest, and almost all of the oil has drained into the pan.

they refer to it as "cold start knock" . but it does go away after 2-3 minutes of driving...

thanks for the info... i did not know this..


Is there like a pre-lubricating system that is available for our engines because I had one installed on the Hummer when it was first purchased because I know it saves the life of the engine since it hardly ever gets drove.

mm never heard of one....just make sure your oil filter got a anti drain back valve...and crack over the key until your motor primes in the morning before starting...works wonders

hows that going to help anything? On colder days, just start the motor and let it warm up a bit before going anywhere.

[spray_bombed]

uh...it lets your fuel pump prime up and get pressure for quicker and easier starting..cars start quicker on cold mornings when you do it....wont do anything for the piston slap though

ok .. that still don't help the initial start up when there is no oil built up already. that is the purpose of a preluber setup !

not be an ass or anything but that has nothing to do with the oil system at all !! that is the issue at hand.... LUBRICATION !!
