Default valve tap on a 2.2

I have a '95 legacy 2.2 in it. It has developed a valve tap. This has been a problem intermittently over the past 2 years. It came and went. However, it has been around for over 3 months now and is starting to get annoying. I think it is from the rear drivers side cylinder. Does anyone know of a history of bad lifters on these? Or any other chronic problem that would cause this?
thanks,
Jamie

If anything, it's the hydraulic lash adjusters in the rockers. They are very easy to replace, although sometimes small pieces of silicone can become logded in the oil port for the rockers & cause the same noise.

I don't think that it is silicone. The engine has never had any work that required any silicone. I thought about the lash adjusters as well because it seems to be the rear drivers side cylinder only. If the oil port was blocked, it should be both cylinders. Next question: Are the heads on a 2.2 like the 1.8? I have done extensive work on 1.8's over the years. The two piece heads make cam and lifter removal in the car easy. Do you have to pull the head to get the cam out to change the lash adjusters on the 2.2?
Thanks,
Jamie

You don't even have to remove the timing belt. It's assembled just like the Ej18 heads. I have had great success just bleeding the HLA's and very rarely have had to actually replace one...

Often times it's silicone from the block halves or oil pump during factory assembly. Just make sure to check the oil galleys under the rocker mounts @ the rocker shafts.

are there any solid adjusters that are available to replace the hydraulic ones in the 2.2 heads?

Some of the later models 96 & up had roller tip rockers w/manual adjusters (no hydraulic lash adjusters)

Thanks! I will give it a whirl. The way it sounds is, it is acutally easier than the 1.8. The 1.8, you would have to take the cam belt sprocket off at the minimum. The only thing that is a bit confusing, is the 12 mm socket with the big and small nipple deal. I am sure, once it is in my hands, I can visualize it much better. Thanks again!

The HLA is a small cylinder, with a nipple thing on it. Place the nipple on the ground and the cylinder will be up in the air. A 12mm socket fits over it nicely. Then, the small box part of the socket (where you would attach it to a ratchet) is perfect to fill with a small reservoir of oil. Hope this helps.

I am very familiar with the lash adjuster. pretty much the same as a hydraulic lifter except with a tip instead of a pocket for the pushrod. I just couldn't visualize how the socket was used. thanks for the description! We Got it now. I will be tackling this Saturday afternoon.
Thanks again,
Jamie
