My Ej25 may be done!

[1-3-2-4]

Not sure yet..

For you that follow on facebook you might of saw my message but for those that have not...

Long story short I had a timing belt that stretched and I locked the ties up without clutching in (jay walker with child walked 10 ft in front of my car at 10 MPH) and my car lost power and stalled. Well I got the new belt on and set up right and it still idles very rough, and given how the exhaust note sounds, it sounds like the exhaust valve is not fully closed.. you be the decider.

From the way the exhaust note sounds (cellphone sounds bad) it sounds like the exhaust valve may be bent and not closing fully, now I come at a time I can go with a '95 Automatic EJ22 with the EGr for a later turbo build, or take the EJ25 out and look at the passenger side head... OR get the EJ22 anyways and put it in and look over the EJ25D at a later time. I have 265K on the EJ25 and it ran smoothly until this happened.

Before anyways says check the timing here you go

So besides the obvious .. what CEL codes do you have? Curious ....
...
Would you not want to just send the heads out to be machined and inspected? Gives you a new lease on your motor.. Fresh gaskets,, all new timing components..

Using old HLA 2.2 heads seems like a downgrade..

the heads already were machined 2 years ago when I did the head gaskets, from what I understand doing them twice is iffy..


And what I would be doing is ej22e shortblock with ej25d heads, and I get CEL for misfires 1 & 3, being that the passenger side jumped 11 teeth I expect some decent contact.

I did the 2.5 heads twice in my BD and who knows if it had been resurfaced before that. You can compensate it by using a thicker head gasket (cometic). Ask how much the machine shop take off when they resurface the heads so you can keep track next time.

Cool, I know they stamped the block with the name of the company but I will ask them next time.. Cool guy told him I would be back.

Do you have a compression gauge? That should confirm or deny a bent valve.

Do you have a compression gauge? That should confirm or deny a bent valve.I do but I don't see what's it's going to tell me after lining up the timing marks it still ran very rough.. 11 teeth advanced is going to have a bent valve no matter what.

You said in your initial post that "the exhaust valve may be bent." A quick check with a compression gauge can confirm your prognosis. If your engine is dead then it is dead. Either fix it or drop in another engine. EJ22 will be have much less power and, depending on exactly which EJ22 you have may require some modifications, but it is a better engine overall.
