Default Help! Please tell me what this noise is.

I just did the head gasket on my DOHC 2.5 and I had some problems with the valves, when I got the heads back from the machine shop all the buckets and shims were just in a box. I have everything adjusted to tollarance now, except for one which is to the looser side. it's supposed to be .25 and it's .30. Anyways here is how my engine sounds CLICK HERE
Any help would be greatly apprecited.

The buckets and shims are out of order,they are not marked either,when they are disassembled you must mark which goes where.Go back to the shop and bitch slap the idiot that did that.

Default Okay what now

So your saying it's that my vavles are still to much out of adjustment? Or are you saying that you just can't put random buckets in even if it has the proper shim? What do I do? And what is the noise exactly?

All the buckets go into a certain slot,if they are put out of order the valve train will be very noisy,I will check with my techs tommorow and see what you can do aside from trial and error.

You need to re-assemble the head and using a feeler gauge measure the distance between the top of the bucket and the camshaft lobe,I will find the measurement for ya when I go to lunch.but plan on pulling the cams and buckets out several times.


Ben,

Good luck.

Ben,

Good luck.
the buckets shouldn't matter

be prepared to replace all the shims and set new tolerances. there is also a tool you will need so that you do not need to remove the camshaft to do so.

you are going to need a good set of feeler guages, a calculator and a service manual for your car because they list the buckets in there, also pick up a metric micrometer, it will make measuring the bucket thickness(if the numbers have worn off).

no, the SOHC is a rocker/tappet system which uses an adjustable tappet to control valve lash.

That does NOT sound normal to me. Good luck man I wish I knew exactly how to fix it but it sounds like you have some help from your friendly neighborhood Naisoc-ers.

PS I'm sure HOK was joking

Default Input

Thanks for the input guys,
I looked into tracking down that special tool that allows for you to change shims without removing the cams and it's $250. I understand how to adjust the shims and I have used a feeler gauge to adjust all the valves to tollance. Only one exhuast valve is off and it's .30mm instead of the .25 or the max tollarance of .27 Is it possible that small differance is the cause for the noise?
Just to be clear, it doesn't matter which bucket goes where as long as it's accompanied by the correct shim?
Also one person mentioned timing belt, if that was off by say one tooth could that cause it? What if I was given the wrong headgasket? If I was given a SOHC gasket could this cause the noise?
