You sir are thinking of flat tappet lifters and lifters in the pushrod sense. HLA's (Hydraulic Lash Adjusters) are typically replaced only in a noise complaint or bleed down situation (or to increase RPM range/adjust for ground down camshafts).

I agree that HLA's are a good idea to swap out as they are old, but it is not required.

GSXBoy-
Have you checked your cam followers? It could be a bearing going bad/flat spot on one of the cam followers (or as others would incorrectly call them, "rockers") How are the cam's wearing in? All the head oil flow passages clean?

Re: Cylinder head noise!
 

All that I did was check and see if there was any play in the rockers.. and the head oil flow passages seemed to be clear. I did not notice any flat spots in the rockers...

Like I said this was not there last year when I parked it so something went bad along the lines of installing new cams, timing belt, and arp's

Kyle from map said that when you put mor aggressive cams in that if the lifters are worn in to a certain point and then you put in say, bc 272's then the lifters have to lift more and the spring is not used to that...

Besides, I had lifter tick not this winter because it was parked but the winter before hand the lifters would tick pretty good upon start up so I'm thinking that this was enough to push the lifters over the edge

I agree and or when your just fed up with all the bull shit then let someone else fix it. I just dont like other ppl working on my car... But thats just me.. even though they are pro's

When I come down to this if its the rod baring then 6 bolt swap time!! I just dont know if I can afford the built one at the moment like I want to do... Kevin ( sleepydsm ) is trying to convince me to do a 2.3 stroker.. I was just planing on doing a built 2.0 but we will see what I can do. I might only be able to do a stock rebuild for the time being but I hate to do the swap and not go all out the first time....

Re: Cylinder head noise!
 

Little tidbit for ya: the 4g63 has no cam bearings.

Re: Cylinder head noise!
 

I didn't want to seem stupid but I was gonna say what bearing are you talking about... lol

Re: Cylinder head noise!
 

did you use oil when you put the lifters in?

Re: Cylinder head noise!
 

didnt put lifters in

Re: Cylinder head noise!
 

Sorry, this is what I was thinking of when I said that. I guess I dont always say what I mean sometimes.

Anyway, I understand you not wanting someone else to work on your car. MAP is the only one besides me that has touched my car. I guess I have known the crew there for a really long time and trust them with anything I got if I cant figure it out or have the equipment to do what needs to be done.

Re: Cylinder head noise!
 

Do built 2.0 now.....

Re: Cylinder head noise!
 

Well I just got the call from map and it turns out that my cams have back and forth play when everything is tight!!!... they said either the cams were miss machined or the head is fucked..... :(

Re: Cylinder head noise!
 

Bummer dude! I would be hoping that its a case of the cams being bad. At least then you could maybe get away with some warranty claim stuff. PITA but at least you wouldnt have to end up paying for it...

Re: Cylinder head noise!
 

Pita?

Re: Cylinder head noise!
 

pita = pain in the ass

Have them try some stock cams in there to see if the head is bad, otherwise send those new cams back on warranty. Maybe the caps were put back on in the wrong order?

Hopefully it didn't mess up the cam bearings :) ... err I mean journals haha.

Re: Cylinder head noise!
 

He said there were no scaring and the caps were put into an order af how they came off and thats how they went back on..

They are going to check the cams and if they are bad then obcourse get new one's under warranty considering they have 1 mile on them..

Bought them from map.. but they said mostlikly it will be the head..

Re: Cylinder head noise!
 

Has the head been machined? Who did the machine work?
This started to happen after you swapped the cams? Was the head pre-existing?

By movement do you mean walking side to side in the head or movement as in the cams slide around inside the cam caps?

Weird shit either way.

Re: Cylinder head noise!
 

the whole engine war remaned and its got 40k on it.. all i did was swap the cams and they told me that he could take his hand to it and force it back and forth while it was all clamped down and torqued..

as in twards the back of the car and twards the front of the car side to side play but mostly on the exhaust one

Re: Cylinder head noise!
 

thanks for correcting me. I'm still in school and it's a lot of info to take in and I sometimes get little details mixed up.

Re: Cylinder head noise!
 

Well the noise has pin pointed and I'm going to start a new thread..
