lifter noise. worry?

[fiveoho]

if i really lay into it, around 4500 and above it starts to 'ping'. cant really make a good description of it. not really ping...rattle. i dunno. the car has 108k on it and never been into. doesnt smoke, runs smooth. no funny noises while idling and normal driving. if i mix a few gallons of 110 with a tank of 93, it wont do it. after i fill up several times after that, it starts again ( only done the 110 mix 3 times in 2 years )

this something to worry about? is it my lifters? is this this a problem?


thanks guys

Sounds like you have your timing set too high. What is it set at?

I agree with 04sleeper, sounds like pinging from too far advanced timing.

Pull that Hypertech chip out and I'll bet it goes away.

EDIT: For a better explaination, most aftermarket off-the-shelf chips advance timing to give you increased performance. The chip is probably advancing your timing too far, especially if you have set your base timing above 10*, to say 14* like lots of guys do.

try better fuel[ chevron supreme works best for my 5.0l]

 

[fiveoho]

it made the noise before the hypertech install. timing is stock.

so am i experiencing detonation?



( i dont have a chevron nearby )

 

[fiveoho]

i will have it checked tho just for the sake of argument. whats the stock timing suppose to be set at? how should i compensate for that with that hypertech chip. main question : what optimal timing can i run to where it wont do that??


if not timing, any other ideas?

 

[04sleeper]

The stock timing is 10 degrees with the spout out. Not sure what the Hypertec chip adds to it.

Try bumping it back 2 degrees at a time until it stops.

Are all of the tune up items in good working order?

What plugs are you running? What gap?

the wires 'look' good . they are fms 9mm but i have no idea how long they have been on there. ive had the car going on 3 years and havent changed them. changed the plugs about 2 years ago. put motocraft plugs in.....cant remember what i gapped them tho

time for wires? also, havent dont cap or rotor either

-thank u for your help

if it doesnt do it when i mix 110 in , wouldnt it be octane related?

Not really. It could just be covering up another issue.

I would do a good tune up. Autolite 25's, New wires, cap rotor.

Then go from there.

i already have a set of new fms 9mm wires at home . i can order a cap/rotor for around 20. plugs are prob 20 or less and i may get a coil.

i think i may try that...tune up. you think it may solve my problem? going to check the timing as well

 

[Jaswir]

bet its timing.... get a timing gun.... just got one for 10 bucks on ebay and its worth 80 bucks if i bought it new.... just something for you to check out... or take it to a shop they might do it for free.... takes 5mins

I wouldn't worry about the coil.

Check the timing and see where it is set at.

I had the same thing happen to me. I ran 91 and it stoped so I checked the timing only to find it was at 13* with the spout out

 

[Roland69]

could also be a biuldup of carbon on top of the pistons causing it to have more compression

 

[fiveoho]

i always run high octane.

seafoam a bad idea or a good one? would that even address my problem?

 

[Roland69]

it wont hurt but I would check your timing befor you do anything It only takes 5 minutes to do. I bet you need to retard it a bit.

 

[Roland69]

I used seafoam in my car...didn't do much......didn't even really smoke much but my truck did.

yea, i will def check it. but i havent changed it and it was doing this before the hypertech install.

5 min check tho is def worth it

i was haering a rattling kinda noise and started using better high octane gas[91] and the sound is gone, before spending all kinds of money try better gas mobile, chevron.
