when i go racing and at high rpm's my valves tick like a motha f**ker and i dont know what the problem is i thought it was maybe he oil pump no pumping enough oil to the head at high rpms but i just go that replaced still does it i talked to some people they are saying my lifters are floating and thats making my valves tick but i dont know please help!!!!!

 

Took me awile to decipher that. Grammar...live it, love it, learn it....thank you.


Is this a TT or N/A that we're talking about?

Anyways....what oil are you using? I have a feeling it's not your valves or lifters. I'm thinking it's detonation, i.e. pinging? What do you have your timing set at? Just for sh*ts and grins....bump your timing back a couple degrees and see if the problem goes away. You are running premium fuel, right?

 

First off like Mr. 91zxtt ask's is it a N/A or TT. Give as much details as possible. RPM it starts, if in all gears, what fuel your using, if you've checked the timing, what kind of oil your using. Need information to give somewhat of a guess as to what's causing your problem.

 

I think hi's name says it's a N/A "ALLMOTOR300ZX" ring a bell?

 

I figured that. but you never know....
Hey Bardabe, you know Skip Fordice in Riverside? I use to race for him out at ascot park

 

yeah its n/a and i us mobil synthetic and premium fuel always. only when i am runing at high rpm's , once i let the car idle for a whie it stops ticking so i dunno what the problem is? how do i adjust my timing back?

 

Sounds like you have a lifter that is collapsing and when you let the engine idle after a hard run, pumps back up again. What RPM's are you turning it at?
If your problem is in fact the lifter then it could be one of two things. A lifter gone bad and leaking down or a weak oil pump. Most likely the lifter.

 

nop never heard of em.

 

When I raced for him he had a HD, Triumph and Honda dealership.

 

in sometime this week Im gonna be living in riverside for just abotu a year I just moved in last Feb so I'm new.

 

someone told me it might be my lifters floating but also i checked my timing and it was advanced all the way from when i got my motor rebuilt so i adjusted it and i am waiting awhile to see if it stops pinging/ticking but its not the oil pump cause i just got that replaced like 10,000 miles ago

 

Then that answers one question an maybe 2. run it and see if it's corrected the problem.

 

thats what i am going to do someone also told me about my egr could cause that if thats the problem you know how i can plug it

 

Your Z isnt a 1996 is it? And i doubt that removing the EGR would cause this problem but here some information anyways as far as removing the egr.... If you do not have an aftermarket ecu you will get a ECU code if you have removed the EGR; however if you have the EGR installed the Ashspec ECU eliminates it anyways. However if you just compeltely take it out it will remove some clutter from the bay and some hoses which might cause problems later, heres a really nice kit for $45 from 300degree, which is run by some of the members of tt.net...

The ASHSPEC ecu program eliminates the EGR function? How? Where did you read or hear of that?

 

Plus his site states that his ecu's are 50 state emissions legal which means that the egr has to be working.

 

Right on CC, Unless it states, " For off road use Only" then it has the egr installed and working.

 

your right i jsut spoke with ash last night on instant messenger and I stand corrected, sorry someone else had told me it had, but he did add that the disablign the egr will generaly not cause you to fail, my bad though on the egr /ecu info

 

Maybe outside of Cali, but it's almost a sure thing you'll fail here without a properly working egr.

 

I m not sure that the ASHSpec ECu elimintes the EGR? I know that the ECU DOES eliminate the the AIV system however. All I did was disconnect the pipes from the exhaust and fabricate some plugs to stop the exhaust leak.

Back to the subject at hand. My car had the ticking problem too. Come to find out it was a bit of trash I guess. I changed oil, flushed the oiling system. Then refilled it. It hasnt done it since. Whatever it was would cause the oil pressure to suddenly drop slightly. But now everything is fine.

What are the legal/ emissions complecations of removing the EDR system. i know I would be all for deleting some crap from under the hood.

 

Here's one thing on the ticking, motorcycle related, but I believe still related. I know when it's time to change the oil in my bike. I here the valves start to tick. Also it'll start to burn a little oil. I believe this is from the oil losing its lubricity and getting diluted with fuel. When I change the oil, the ticking and smoking is gone. Without a odo, I change the oil after approx. every 20 hours of running the engine.

On the egr (edr), it is technically illegal to modify or remove any emissions equipment on a vehicle certified by the EPA in this country. It is actually a federal crime. Some states check and some states don't.

There was a big hoopla at, or around, the last SEMA show, where some feds actually filed criminal charges against some companies that sell products that requires the removal of safety equipment. The one company that I heard about sells aftermarket steering wheels. Which, of course, requires removal of the air bag.
