Default Phase I ej22 with phase II head gaskets.....is there a problem?

Hey all, just got done doing a lot of maintenance on my wife's '96 Legacy Outback. One of the things I did was replace the head gaskets. Since I was in there I thought I would drop in phase II head gaskets and get a small CR bump. Upon starting it back up it is extremely noisy. I know that the valve train is loud and will quiet down a little after a few days but when I rev it I think I might hear valves hitting the pistons! This has me worried as I don't want to destroy my motor by driving it around if the valves are contacting the pistons.

When I first put the timing belt back on the car I made sure to do it right. I spun the crank several times and all of the timing marks were still lined up. Upon start up it immediately jumped timing. It ran for about 8 seconds like that at a low idle. I thought maybe I had just timed it wrong and went to do it again but then found out my tensioner was dead. I got a new one and now I need to know if I made a horrible mistake.

Thanks,

Geronimo

If you think the valves have contacted the pistons, don't start the car at all. Remove a spark plug, and look inside the chamber (won't be easy) to see if there are any marks on the piston.

I wouldn't think that using a HG that is about half a thick, on a block that has pistons with valve reliefs in them, would contact the valves. Can you post a sound clip or video to help diagnose?

IIRC, from 97 and up, the motors are interference, before that they weren't, at least, that's what I remember.

Well I know the EJ25D has pistons that clear the deck and you NEED the thicker gaskets and I think the P1 2.2 is the same way. So the piston might be hitting the head.

Well I certainly feel like an ass right now. I know for a fact that the P1 pistons clear the deck as I observed it first hand. I did not even think about that. I will pull a spark plug and take a look inside to see what's up. I had to drive the car about 5 miles last night to get home so I hope it's not a total loss. Sometimes working on your own car can save you money....and then you make a mistake that makes all of your hard work a total waste! If I had the money I might be tempted to buy newer cars that are still under warranty and just sell them everytime the warranty is up. I wasn't raised that way but I can't stand having to do this big of a job more than once in so short a period of time. It wouldn't be a big deal but my wife needs her car.

So if the valves have contacted the pistons what am I looking at for a fix? Replace valves and pistons and I'm good?

Okay, so when I drove it home last night my alternator/ps belt came loose and I ran on battery for the last mile. Long story...a couple of years ago I was on top of a mountain and the bolt for my alternator belt tensioner snapped. I stole one from the ps pump bracket and forgot about it. Last night when I put it back together I stripped the threads out of the alternator (the bolt was too short so it only grabbed the first few threads). So when I got home I didn't get to hear the motor. I just came home for lunch and installed a new longer bolt and decided to start the car and see if anything had changed....

I can't hear the sound at all!!! It must have just been the valve train. I cleaned the heads really well and ended up flushing most of the oil out of them so after driving it home last night everything seems to be great. I will drive it to work and make sure there are no leaks or anything.
