Angry Solid lifters?

My car was in the dealer for a ticking noise on startup. They say as the car has solid lifters, and not hydraulic, the sound is NORMAL and there is no problem.

(ME)Q: Why then, have I just recently started hearing this noise upon cold startup?
(DEALER)A: It's the engine breaking in. You have some miles on it (50,000).

IS THIS BS????

Nevermind, saw your other post. The DOHC EJ25 is indeed solid lifter. There are no lifters in the SOHC EJ25.

Oh, and by the way there is a tolerance limit for valve lash. You could demand that they inspect it and if it's out of tolerance they will shim it back to the minimum lash. Unfortunately if they pull the valve covers and it's within tolerance you're out some bucks for their time.

Exclamation

Here is some news that will blow your socks off. Did you know that Subaru first offered the EJ25 in 1996? Yep. It was an optional engine only available on the Legacy Outback wagon with AWD.

Now for the kicker. The 2.5 that was offered in 1996 was quad-cam and had hydraulic lifters!!!! 1996 was the only year that the 2.5 came with hydraulic lifters. If you could find one of these motors it would be a rare find.

Thanks ColinL

I think i'll skip the tolerance inspection...the noise is only when it's cold on startup for a few minutes. It was just that I'd never heard the noise before, however slight.

Do you agree with the Subaru Rep, that this is normal? Or do you think (like I do) that he just doesn't want to touch it because it has 50K (almost out of warranty)?

Thanks

If it's only on cold startup it is probably NOT valvetrain noise. If it were valvetrain noise, it would probably make that noise when warm and at idle.

Have them look at the belt tensioners.

I've also seen some 2.5's with noise when cold- the cause was piston slap. Not an uncommon problem due to the pistons having very short skirts, thus causing them to rock ever so slightly in the bore until the piston/cylinder heat up and expand.

Yep, the 98 DOHC have solid lifters that make noises when cold. They also use shims to adjust the clearance which adds to the noise as well. I wouldn't worry if it goes away after a few minutes.

As for the piston slap, that's a real problem. I had that happen in my 2.5 DOHC and had the dealer swap out the pistons with "countermeasure" pistons that are supposedly machined to tighter tolerances. The hard "tapping" that was indicative of piston slap was fixed using these different types.

Um, Avoid the 96 EJ-25, as they SUCK. They have the lowest power output of any of the 2.5L motors, require premium, and from what I have heard are just waiting to puke.
