V10 piston slap?
Hi all,
I'm new to the v-10 and basiclly any newer ford engine. I have had many 400's, 351's 360's 460's ect. pre 1980. i love my old 1978 f150. any how i have a 05 excursion with the v10, it has a knock at startup last maybe 5-10 seconds. it sounds like a light knock harder then a valve click and softer then a rod. I also had a 2001 chevy silverado with the 5.3 v8 that sounded exsatly the same that has done it for 7 years and never been a issue and chevy claimed it was from the Piston skirts being to short and caused a slap in which i have seen several of those 5.3's go over 200k miles w.o a break down due to piston slap. My question is if any of you know that maybe the v10 has a similar issue and if i should be concerned. i do know it has a exsauste leak tick but other then that it sounds like its in between a rod bearing and lift or valve tick. Any info would help
thanks for your time.

The earlier 5.4's and some v-10's had piston slap issues but not the later ones.
If it was mine I would fix the exhaust leak first.
Depending on your mileage ,then I would look at all the cam followers.there were a few that had them become loose.
Tell us what kind of oil and filters you are using.
After i hear what your using ,we can give some more advice.
Certain filters have crappy anti drain back valves.

The V10 needs a oil filter with a good anti drain back valve to keep the oil up in the motor so it's best to stay with a Motocraft filter. Our V10 has had a tick on start up from day one 9 years without any problems, I think it's a lifter (cam follower) that drains down after sitting. I just makes noise for a couple of seconds and then I never here it again until the next time it sets and I start it up.

my V10 does the same slight tick for about 1-2 secs when its not been started over nite..
but if its shutoff for only a few hours/work day it starts up quiet..

Mine has 137k miles on it. has the motocraft oil filter on it. The tick is happening 24/7 while running, but a difirent one for a few seconds on start-up, only when sitting over night, if u restart it once warm it doesn't do it, its on a fresh oil change at the moment. What i thought was exaust leak tick may be that spark plug issue i have been reading about so im going to check that out today. Thanks for the help and still looking forward to seeing any other ideas

o and using 5w-30 oil. winter soon here tho i am thinking of going to a 10w-30 for high mileage. i used to run 10w-40 in my older ford trucks w/o and issue, is it wise to do that with a newer engine? even tho it has a few miles on it?

If you guys even suspect or know you may have an exhaust leak, fix that first. A tech at a well know Ford Truck dealership around here told me my valves might be sticking. Turns out it was only some leaking manifolds that led me to put on a good Banks header and muffler unit.
