Ticking - hopefully not valves.
Lately I've been getting a tick, tick, tick only when the rpms reach anything over 3k and typically NOT while under load. If I keep it at say 3500 rpm, I get a constant ticking.
I know what you're probably thinking - lifter tick, right? I actually don't think it is. I had lifter tick for months but that went away a few months ago when I had the 2nd gen lifters put in along with a full 120k service (timing belt, accessory belts, oil pump, etc, etc, etc). This ticking is about as loud as lifter tick but sounds slightly different and I think it's strange that it only happens after 3k rpm. Also, if it starts ticking and then I accelerate, the ticking seems to stop until I let off the gas - then it comes right back (assuming I'm still over 3k rpm). I was wondering if this could possibly be some contact between the pistons and the valves. I really hope not... I've got a data logger hooked up and the timing seems okay (I think) but maybe the valves are sticking a little bit? This may have something to do with it: Just the other day I noticed the oil was about a quart and a half low  I hadn't noticed any leaks and the pressure seemed normal so I hadn't thought to check it. I had my oil changed maybe a month ago with some synthetic (or partially synthetic) Mobile 1 5W30.Alright, I could go on and on... If there's some more info I can give you that would be helpful, please let me know. I could take a vid, post logger data, etc. Thanks in advance for your help! |

Re: Ticking - hopefully not valves.
I'm still thinking its just lifter tick, u could bput some rp in there, or sea foam could do the trick,
by 2nd gen lifters I assume you don't mean '99 lifters as those are the 3rd gen. I would've gone with the 99 lifters that have the larger opening (3mm i believe) which would get rid of your ticking. Let me know which you put in there, and maybe its not lifter tick, but i'm leaning toward that

Re: Ticking - hopefully not valves.
Ah, yes, I did mean 99 lifters. I didn't realize they were 3rd gen but they are the ones with the larger (3mm?) opening. They're from the group buy that I found on here.
If there are any relatively easy ways to rule out what the sound could be, that would be good to know too. |

Re: Ticking - hopefully not valves.
i say its probably lifter tick. What kind of oil are you using?
I still get it every once in a great while. I also get it a little more when i drop down a little bit in oil level. (damn rear main seal!)

Re: Ticking - hopefully not valves.
Right now it has Mobile 1 5W30. It's either fully synthetic or the synthetic blend. My mechanic put it in so I'm not sure exactly what it was. When I replace it again I'll probably use Redline 5W30. I had that in there before and liked it.
I know many people on here use heavier oils and say it reduces lifter tick but I read a really good article on here on the subject of motor oil (not sure who exactly) and it recommended "thinner" oils for more flow/lubrication when cold and at operating temp. Also, now that I've topped off the oil, I think the tick is dying down again. It could just be my imagination... I really hope you're right that it's lifter tick. |

Re: Ticking - hopefully not valves.
Evidently they didn't get enough oil put in with the change a month ago, or your losing oil fast from somewhere.

Re: Ticking - hopefully not valves.
In all honesty I think you have nothing to worry about. Personally I have the stock lifters in my '94, they ticked like crap when I got the car, I changed the oil to 10W-30 Mobil1, same thing... month later decided what the hell, i'll see what the royal purple hype is all about, plopped some royal purple 10w-30 in there, week later tick went away and here I am without lifter tick
Very happy =] -Steven |
